10 Engines That DIE Before 50,000 Miles (Because They Are JUNK)

some manufacturers go out of their way to make sure that car will last the lifetime and yet other manufacturers just can't get it right we're going to talk about today 10 of the worst car engines that won't last 50 000 miles no matter what you do let's get into it now Life's too short to drive boring cars let's just get right to it the first engine that's one of the worst not necessarily in this order is what's in this vehicle behind me everybody said get the V8 you need lots of power the V8 has power to pull the V8 sounds great it's amazing well let's talk about it because it's not quite so amazing in this particular generation of a BMW the engine you find in this vehicle obviously isn't more than enough to get it going along obviously BMW and the traditional trademark grills as well as those Angel Eyes make this car very desirable in a lot of circles unfortunately the engine that you find when you're associating it with the X5 50i is where you have some of the issues because when we're talking about that that generally means and regions that are identified within the 2008 to 2012 model years that have that 50i designation and don't begin and end with just the X5 you can alsify them in 5 series and 7 Series cars and that is the wonderful BMW n63 one of the early Generations now they have gotten a lot better but this first generation of that V8 is absolutely breathtakingly ruthless and why is that and what's actually going on with that type of engine let me explain first of all we won't even talk about that generation of vehicle anyway with some of the other problems with electrics air ride suspension that drops because the airbags start to let air out most of the issues are related to that engine when we're talking about the 50 Series it's that hot V because it's a V8 in the channel they've decided to put two turbos in there and those two turbos generate a lot of heat because exhaust temperatures make excessive heat it gets glowing hot and that glowing hot heat actually starts to melt out Parts within that via the engine of course it takes a toll on gaskets so you get leaks both coolant oil oil leaks wiring Plastics all of the other parts great some of that's cosmetic some of its coolant leaks of course you do get coolant leaks because that's one of the problems water pumps thermostats the other issue is because those leaks you end up with a situation the results in excessive oil consumption because you end up with the valve guide seals that guide the valves and keep the oil below the engine those start to melt too unfortunately because of all that exhaust damp heat and then you wind up eating lots of oil these are oil eater 9 thousands unfortunately so then you have a heavy oil consumption coupled with the fact that BMW said BMW care they're going to try to take care of some of the customers allegedly that was really just moving people along to try to coach them and basically say hey look we'll try to take care of it as best we can it does ultimately often mean new rebuilds or engine top ends but there's a lot of problems with that there's also excessive battery draw just has to do with that vehicle in general but related to the engine you do also have other big issues for example fuel injectors they say leaking injectors are one of the big problems here with that engine as well and because of that what ends up having the fuel winds up going down into the cylinders leaking down it doesn't necessarily leak externally it leaks internally and then you wind up with washing of the cylinders if you wash your cylinders that takes away the oil film no oil film move that cylinder it starts to scratch the internals you get the rest right so the engine becomes toast in a very short period of time if you end up losing injectors another big issue is the timing chains timing chains on these vehicles that keeps the Pistons and the valves in synchronization so you bring in fuel exhaust and Spark and all that good stuff if that synchronization goes out of whack you basically can wind up with piston and valve connection and catastrophic boom and then your engine's toast again so that's another big issue because those timing Chains would stretch or sometimes the ramps would break and let go and then you'd skip a cog so clearly it was a bad design right from the get-go I guess fundamentally it was a great design in practice and execution not so much instead if you really have to have this generation of BMW also doesn't come without its issues but for example or you go with one of these particular vehicles it's the 35d yes you can have still some of the airbag issues and you do have their own sets of problems but the engine fundamentally is very solid on one condition you do the full EGR DPF delete on that vehicle then you have a fundamental engine that's strong good for a lot of miles I had one and the only place that kept dying was on the DPF heater system EGR and all of that plugging off get rid of all of that do a full delete and that engine is good for a lot of miles ours was at 140 000 Miles when I sold it and the gentleman who took it before was going full delete and now he's good probably for another 200 000 miles so if you need to have that generation go deleted X5 diesel and another one is the engine that's tucked in this beautiful little car and when I say beautiful I mean it they're fun they're great looking vehicles and with the right engine they can be a blast as well as the right transmission but unfortunately there is an engine configuration you want to avoid like the plague but let's take a look and I'll show you even this one here I saw being towed in the other day and I'll show you some something why I'm just confirmed in saying what I'm saying I mean clearly this is a mini which is also built by effectively BMW but the engine in that under that hood is a collaboration between BMW Peugeot and Citroen that's right this one obviously was towed in there beautiful headlights look at the plastic finish on there this is Baker Street style in the house obviously look at those great little retro mirrors and lots of sun coming in through the massive sunroof right there hot little exhaust tip there and look at these beautiful wheels absolutely gorgeous little car retro styling all the way around but look what I found on this vehicle they literally say do not start the engine probably because there's something catastrophic about to happen there or just did so the engine I'm talking about is the 1.6 liter they call it the prince engine and it started from back at about 2006 till present and it literally has problems Galore now again as I say there's engines that you'd probably want to ramp up to this isn't necessarily one of them fuel system related issues as well as poor running can contribute to this car's problematic areas and other issues are the timing chain that coordinates the timing of the valves and the Pistons can actually slack off and become loose with time and when that happens you basically got a condition where the vehicle runs poorly sloppy and you never quite really know why and you end up chasing problems like fuel injectors and Spark but yet it relates more to timing that's off that far EGR valves exhaust gas recirculation is a problem with almost every model diesel or gas as well as the fuel injectors are known to have bad seals that let fuel fumes waft into the engine and even into the cabin which makes it very uncomfortable annoying and potentially dangerous right if you have open fuel Open Flame all mixing together it sounds like a recipe for a disaster so clearly not a great situation if you need to have one of these vehicles go with the turbocharged four-cylinder or Cooper S some of the later generations past 2014 stick with maybe a 15 or newer model year and you could get yourself an fun frivolous little Driving Experience in the BMW Cooper the next dumpster fire engine that wouldn't make it up to 50 000 miles without doing some major intervention is what's behind or under the hood of a vehicle like this well what exactly are we looking at here well clearly a big domestic boat but what is it well this is the Palm Springs special as you can tell yeah because it's a Cadillac and look at all the quality on that trim beautiful headlights but back in 2000 s is where things really went wrong for this brand yeah they wanted to use that big powerful V8 engine yeah they've got some great touches no sunroof on this tank but they do have the chrome rims which again is great for Palm Springs here big beautiful tail lights and you got a set of quad exhaust tips and what we're talking about here is the V8 North Star engine what we're looking at here is a DHS but realistically DTS is what we're talking about here so many problems where should we start and where do we end I could talk about this all day but actually let's take it from the top you can get valve cover gasket seal leaks carbon buildup in the engine which is easy to fix you just got to do some low-cost maintenance but it's a problem compression was also altered because of some of that carbon buildup but piston rings here as well were a common failure point and led to massive oil consumption so you actually had heavy oil carbon buildup leaking coolant water pumps would fail the rear main seal that goes out to the drive to the transmission would known to a leak as well so you'd wind up with a puddle of oil underneath and this thing leaked consumed burned oil coolant Every Which Way from inside out part of that was also because the infamous valve cover gasket you'd blow a valve cover and then you'd essentially internally start eating some coolant that's a bad scene because you start gobbling up coolant you misfire you also introduce moisture into the combustion chamber which is never good and you wind up with black exhaust smoke coming out the tailpipe it wasn't also uncommon to experience oil pump and hey if your oil pump lets go you don't put oil into the engine where you need it and then you basically go boom also water pumps were notorious for these vehicles so not only did you leak cool it externally or through the blown heads but you also had water pumps that often would give up the go so it was just a poorly built engine nobody who ever owned one of those Cadillac engines ever was very satisfied with it and they guaranteed did not last over 50 000 miles the next engine that's horrible that'll clearly you'll find in one of these you'll find in many other vehicles like Volkswagen passats as well but we're looking at the Audi A6 97 to about 2005 and there's a series of turbo diesel engines a two and a half liter V6 lots of problems yeah it had a lot of good performance but it had a lot of negative attributes and you could tell this older generation of Audi A6 just by simply looking at some of the headlights you could tell that's the older generation and this older generation here too The Grille the headlights clearly older style Audis this one here has been rode hard put away wet and a little bit of crust around the edges a vehicle that's seen some of its better days but it's not about the exterior it's not about the paint or the scratch or the rust or any of that it's what you'll find in some of these vehicles like the Passat or this Audi A6 including the all-road are some of the engine codes like afbakn Ayn BC Zed BDO a BFC AKA BAU and bdh that was a mouthful but yes you can also find them in skoda's like I said within the vag group that engine was quite prevalent now it had great performance and it was actually quite economical but there was an inherent issue and some of it was a contributory because the brand actually advised on extended oil service intervals and that led to a catastrophic issue which you'd find in a lot of these engines preventing them from running all that long and 50 000 miles would be a stretch to say the least which is ridiculous because most diesel engines are inherently designed and should be designed to run hundreds of thousands of miles but not that one one major issue that contributed to actually having to rebuild engines and them not lasting at all that long or the camshafts would wear up way prematurely the camshafts essentially are those that are connected to the ends of the valves and drive your valve train allow fuel in exhaust out and those camshafts the lobes would wear down and then you'd find yourself with poor running conditions and situations where that vehicle just wouldn't run properly at all check engine lights and just a host of other issues other unfortunate problems with some of these are the thermostat that would actually plug off and the thermostat's what opens and closes and allow the engine to evacuate heat or not but and sometimes the thermostat we jam up you overheat that engine water pumps another problem they leak and they'd fail as well as oil pumps turbochargers as well a big problem turbochargers blow you're dealing with a three or four thousand dollar repair so whether it's turbos water pumps thermostats even O2 sensors and leaks intake manifolds unlike there are way too many issues in that two and a half liter turbo diesel engine even to assume that this thing will go any significant miles another major engine problem is related to the specific brand here not this Forester per se with the 3.6 but there's other issues and the ej20 engines Subaru is actually known for a high level of reliability a lot of their engines will run a long long time so this isn't a knock at the whole brand because the brand in general is quite durable however there are some problems with specific engines and they definitely won't last or they'll cost you a lot of money out of your hard-earned paychecks I mean if you're talking about the ej205 207 and 20g engines they have a lot of issues related to the intercoolers for the air conditioning you all also have stuck piston rings which is a bad scene because if your piston rings stick up in the cylinder basically a seized engine so that is a problem that's common and it's related to the treatment of that piston ring and clearly would need some sort of an engine rebuilt to unlock that engine then we talk about the ej20 as you'd find over in other cars for example like the Forester Legacy and the Impreza which this is a WRX but essentially the base model imprezas carry the 125 all the way up to 140 horsepower any versions and that basically you wind up with a knock and cylinder number four they are four cylinders so you end up with a knocking noise knock knock knock knock knock knock knock knock and they're also quite prone to seal leaks and leaking oil all over the place through various seals and gaskets so not a great engine again not necessarily the WRX STI versions but certainly the bass imprezas there's also very specific number of these Subaru engines that actually have blown head gaskets they comes on very very quickly and easily I as a matter of fact had a friend that had a slightly older generation of Subaru Forester the old school the old boxy style as it were and he actually had an engine that car was treated immaculately oil services way before their time took care of it to the T and still wound up with an engine having to be replaced he took a trip up to the mountains at a little bit of an acceleration up the mountains and all of a sudden blowing smoke hearing the knocking noise and it needed an engine so a sad State of Affairs there are some weaknesses within the brand generally as a whole they're pretty solid but the EJ series 2025 are ones to look out for so what does this vehicle this one an Optima Forte and a Sorrento all have in common while it's the engine that you can find in some of those vehicles that goes back several years and there's been so many recalls because of one key issue well let's not get silly there's actually many recalls 60 recalls in fact because of engine issues and the engine in question that has caused lots of Heartache are the Theta 2 engines the GDI engines and the gamma GDI engines now what's so bad about those engines well other than the fact over 3 000 fires have occurred and over a hundred people have been injured and even worse in one case means that the national highway Transportation safety administration is all up in their business over some of these engine issues yeah well what's causing those engine issues well a lot of times you don't even know check engine light Booth car stops other cases knock knock you're hearing a knocking noise and all of a sudden lo and behold the engine just boof makes a loud noise and clunking stops other cases it blows up in flames and you have Flames billowing out from under the hood let's not fool anyone here this is a scary situation and the recalls have been there to actually Supply support for people who are on the wrong end of that Spectrum It ultimately means many replaced engines on behalf of key and Hyundai which is their sister company who also have the same issue because they share the same engines and quite frankly it's more than an inconvenience and allegedly the companies were very very slow in reacting with the first cases started coming in then hundreds of K cases came in then thousands of cases came in and it could not be denied because engines were getting replaced left right and Center a lot of people were struggling getting those engines replaced or getting rental cars to replace what they were offset by it was an ugly situation and now key and Hyundai are having to pick up all the pieces that fell on the ground or the smoke that billowed into the sky the reality is it doesn't take very long to look around to find vehicles that are subject to that recall there's also been other recalls recently with Kia related to piston rings and bad treatment and issues with them locking up or air conditioning system problems and abs modules failing and blowing so the bottom line is it's a problematic engine configuration and while you'll find hundreds and thousands of people who are very satisfied with the latest generation from this brand the reality remains those two engines are ones you definitely want to stay away from they won't last 50 000 miles at least without rebuilding or replacing the engine the next engine 4gr FSE V6 yeah that's the engine I actually what's tucked under that hood and for those of you who don't necessarily recognize the nilman clature let me spell that I can make it a little simpler here for you every manufacturer that even the best Toyota has a misstep once in a while we know sudden acceleration they had porous engines they had little problems here and there and this is one of those missteps and this is a Lexus which is clearly a Toyota product but let's take a look and I'll explain some of the key issues that they've had here it is a gorgeous looking car look they do have that big mouth grill that they came out with in this particular brand you do have the check mark and beautiful Wheels this one's the F Sport Plain Jane little mirrors Simple Touch access getting in and of course there's no sunroof on this unit here beautiful tail lights as you circle around and look exhaust tips right there all carboned up and that's the point because this is an is-250 now don't beat me up too badly I know a lot of people will say oh just use a catch can and do all these things in regular servicing Life's good but the reality is that engine wasn't all that great it was a bit of a misstep and try to quickly figure it out carbonization is the big one they're sluggish they're weak and they're not necessarily built for longevity like you would expect from the other version of the three and a half liter V6 is clearly the engine you want this is not this is one that they just sort of missed the boat again if you do extra maintenance above and beyond you might get some miles out of it but this car and this engine isn't necessarily built for the lifespan Now 50 000 miles might be a stretch you could probably do some decent miles if you do the maintenance if you totally neglect it this car will fall apart this car is the one that I have to use with a bit of a caveat if you do the maintenance so it's a great car in general Lexus Toyota almost unbeatable but this is one of those little specs on the mark of the brand and here's one that really pains me to talk about this way because it is such a magnificent vehicle to drive and it's this car in front of me here and it actually carries an engine that's ruthlessly unreliable actually to the point where you probably won't get 40 50 000 miles at least not without doing some major engine work and when I mean major if you have to tear apart the bottom and change out rod bearings of potentially connecting rods that's pretty major I would say that usually means pulling subframe dropping a whole bunch of Hardware suspension parts bottom end and getting a real expert mechanic to actually repair that for you but what is this and the kind of car we're talking about well there's really only one type of car that that engine carried in and in this BMW world but let's take a look of course you do have the angel eyes with the traditional kidney grills but look snarling nostrils this here is a specific three series car but what kind yeah you do have the aggressive front spoiler beautiful Wheels in BMW's fashion look it's an M3 and look beautiful mirror of course they have that cool little break right there and this one here is a convertible as you can see it splits into multiple pieces the interior is quite attractive and it wears very very well that's one thing BMW does well of course one touch access in circle around and of course this is the generational tail lights from that time you do have a set of quad tips it's a gorgeous car in many many ways this particular one is in convertible format but you can also get this in a second down it's from a generation when they didn't have m4s and they didn't call an N4 or two-door this was either in a two-door or four-door version you could get the E90 e92 and at the engine that we're talking what is the S65 right the S65 which is a smaller version of the s85 which the infamous F1 derived V10 engine from the M5 in the same generation but this engine lots of problems water pumps thermostats it eats that water cooling lines everywhere this will lose oil this will lose coolant and more importantly this will eat rod bearings after 40 50 000 60 000 miles is a stretch and you're having to tear into it to actually make sure you replace them on time because these are catastrophic time bombs we also can't forget about the throttle actuators when they go Bing check engine light limp mode and there's a whole host of other knickknacks and tallywacks in there that cause this thing a problem so sadly the S65 by BMW beautiful car sad display of failure ship many of you are very well aware and well versed in this BMW 3 series 2007-2012 but it's not just restricted to that there's an engine under this hood that is known for Mass amounts of Heartache heartbreak vomit sickness and just a downright disappointment with the brand well I mean a lot of the three series cars are very fun to drive and let's take a close look and understand why and I'll talk to you about the engine that's tucked under this hood here here we have a later version you can see the update it's a facelift version of the E90 e92 generation from 07012 this is the later version of course you do have these interesting little eyebrows there and they have the smaller Wheels here this one's X drive that means it is all-wheel drive and of course small mirrors of course we also have a sunroof there which is good and easy touch access around we circle around we see this style generation of tail lights it's a beautiful car if you look down the sight lines it's absolutely wonderful the interior is looking great too but if you look under here somebody's gone and ordered some parts from World pack there's a box of parts and goodies for this vehicle it looks like based on that part it might be something some kind of a sensor could be a group of plugs it just could be something catastrophic but it can't be plugs actually in this case because the engine we're talking about that is a beast of burden in 2007 to 2012 has to do with a diesel engine that's right it's called the n47 it was ruthless the same thing as the N20 which was the gas jobby the n47 that we have here is the turbo diesel and it was ruthless now typical BMW fashion you anticipate electric issues and all those types of fun and frivolity but the big issue is the turbo diesel engine other than the carbon issues that you would expect here there's no spark plugs because it is ignition compression and yeah it's diesel so it's a diesel engine that's known for timing chains so you start the engine up and you hear a little rally rattly but not your typical diesel rattle more of like a dragging noise a noise that's out of sync it often gets worse and it often even gets to the point where it just catastrophically just boom and then the timing chain lets go because that's from the same generation as the the N20 the gas jobby where they had plastic timing chain ramps that were actually the guides that break and crumble and then they'd come apart and then you'd have slack in your timing chain and of course if you have too much slack you could skip a cog and you have a piston and a valve deciding to be best friends and giving each other a great big hug but that's a reality with the n47 one that likely would not have made 50 000 miles particularly in the earlier generation because of the imminent failures and before we get into the last one right there be sure if you want to support the channel right there hats shirts jackets you name it just click above there it takes you into the store it's just a great way to Port as well as show that you are actually part of the Exotic Car Play Place experience but now let's get into number 10 and we're talking about an engine that you'll find buried under these vehicles now what do we look here this here is a Volkswagen Jetta you can find in golf Audis a3s A4 skoda's you name it the vag group special that's right there's an engine associated with this that have lots of issues now it's specific I'll mention it's a diesel and diesels in these vehicles were also very very popular I mean these cars came with great alloy wheels simple little mirrors of course you can't recognize the mark IV front end on these vehicles you do have these style of headlights which is a bit of the transition to the newer design theme of course this one's Volkswagen as you can see that's sort of the giveaway on this design lots of people carry stuff on the roof because these are very versatile vehicles for the people but what specific Arcana issues before we actually tell you what the engine code is Volkswagen's used a couple of different fuel injection processor systems Siemens and Bosch it was a Siemens system that seemed to be a little more problematic in the way the vehicle would operate and so Bosch was clearly the favorite the Dual cam systems in these vehicles had problems with turbochargers the Dual Mass flywheels and many of the other electronics that I already mentioned because Siemens was actually a more problematic system but unfortunately it was the balance shaft was the large part of the engine problems here now we also know Porsche to struggle with a lot of intermediate shaft issues and very similarly we have a problem here and more vag products like we're seeing in this car again in theory turbo diesel engines are made to run a long time and sadly this one was one of those rare exceptions where there was just way too many problems with it and so what kind of engine code can you expect to avoid right now well you really want to avoid this engine which is called the ea188 and it's specifically the one with the Piezo injectors those Piezo injectors are huge money we're talking about 1800 to 2 000 each if they blow and they're commonly fail points so definitely one of those vehicles with the problematic engines you definitely want to avoid like the plague because it won't make 50 000 miles and with all of that said check it out right there that is some of the most reliable engines on the market today hope to see each and every one of you on the next one we'll see you real soon bye-bye
