I have a Veloster R-Spec with a little 1.6 Turbo (Tuned to 250 Whp) Smartest thing I ever did was to put a dual catch can system in place to minimize blow-by. I have caught A LOT of contaminants before they made it back into the engine. Also, with these little GDI turbo motors, you're getting a lot of LSPI issues. People crusing at 45-50 MPH floor it and the load on these tiny engines is IMMENSE. Cracked rods, pistons and windows in the block. Thankfully with a manual, I make sure to always down shift to get the RPMs up and I'm good to go. Manufacturers have done a poor job educating people how these new more efficient engines work. They aren't like the V6 motors back in the day.
All of the people hating on GM have a valid point, but I've had a Mopar warp a head in 30K miles and two Fords shatter pistons. All were driven lightly and had regular maintenance performed at factory intervals. That's what finally drove me and my family to Japanese cars.
I've also seen Mazda and Mitsubishi motors blow rods out the block, and I have a GM with 300k miles on it. I think shit just happens sometimes, not every part comes out correctly.
Koshunae yeah but every manufacturer has had design problems. My point was more that anecdotal early failures are not reason to condemn an entire manufacturer. Especially since Chevys are more often manufactured outside of the US and most US Toyotas are made in the US now, saying 'American cars are the problem' doesn't make any sense. Have to judge each specific model by itself, everything changes every year when it comes to which car from which manufacturer is most reliable - and then you have to consider maintenance.
thats the "mark of excellence" 19 thousand miles and already needing a rebuild you couldn't give me a NEW GM vehicle. i laugh every time i hear GM has cleaned up their act and i see videos like this......same SHITTY company that sells a car that once you finish paying it off its time to junk it and buy another one they have followed this business model for over 50 years......
Given this is part of a rental fleet (sticker on driver's window gives it away) there's probably no warranty, but the rental company will have to butt heads with Chevy.
SavageSalad so you wanted to put hard working. Americans out on the street cause if GM didn't take that bailout that's what would have happen next time think before you shoot off your man come on I'm just sayin
problem is that its a form of socialism, real capitalism (the freedom you americans always go on about) allows bad business to fail without exception, the true solution is not a handout to bad policies but a tariff on imports to prevent non American products from dominating the market
Actually the Cruze was a better handling better riding car as well as better looking but since it's her first car I wanted something reliable. Some GM models are scary when comes to reliability.
DustinB855 whyy fix something that isn't broken.. seems as though car companies like to rush things out expecially when they come out with something new.
Yes, i agree, in a rush. I just can't believe that the piston problem didn't show up during testing. The Samsung phone catching fire is another one. Trying to beat Apple with a new model. I like Samsung but it looks good on them.
Thanks for saving me a lot of grief, Daniel. This video is one of the reasons I just traded the 2016 Malibu I bought less than a year ago for a 2015 Camry. It was doing the exact same shit. GM said it wasn't "out of spec" (classic sidestep) and it still ran decent, but I wasn't taking any chances. No plans to buy GM or any of the Big 3 in the near future.
@@joshuarivera428 They weren't always. But they started going down the tubes the moment they started diminishing brand identity around the late 70s. Then they took it a step further by canceling all their best engines. Their dumbest move ever was canceling the 3800 engine. The POS 3.6 that 'replaced' it is a throwaway at 90-100k miles.
@@anonymousinc6330 even '80s and '90s GM cars were infinitely better than the bullshit they make nowadays with the excuses the lies the deception the government bailouts doing everything they possibly can to dodge blame and make someone else responsible for their faults it's absolutely disgusting
@@anonymousinc6330 around here in BC I see tons of older GM cars still running from 90s to early 2000s Malibus and Impalas and GM era Saturns and an impressive amount of sunfires and Cavaliers occasionally very early '90s and late '80s GM cars popping about here and there
@@silasmcgee3647 Oh yeah, GM built some of their best cars from about 1985 to about 2003, there's no question of that. But since 2006, everything has been junk.
fuckin auto manufacturers shit gets more expensive and less reliable each and every year. pisses me offi always buy low miles used vehicles from early 2000s 90s and 80s
Such a shame seeing so many newer cars have issues. My 2007 Cobalt LS with the 2.2L ecotec is running like a champ at 150k miles. Only issue is a bad anti-roll bar end link. Mechanically it runs great.
My Cobalt sitting at around the same. 'cept the engine was swapped at 80k miles so I'm doing things like fuel pump n throttle body, those parts are all somewhere around 240k and still most are still kicking like a champ😂
The Tool Guy no,he's just stating a fact. GM sucks ass,they've been making cars for a hundred fucking years and they still can't get it right,not quite as bad as Chrysler but close. And I used to drive GM products but had way too much shit go wrong so I bought a more reliable brand and haven't had one thing go wrong in 20 years with any of these cars,and I drive them hard and put a lot of miles on them. 😎
I always thought it was hilarious when people claim that one American brand of car is better than another. It's the same thing as saying Natty Light is better than Milwaukee's Best Light---it's the same low quality shit, engineered to the same low standards. No doubt someone will write in about how their full size American truck has a gazillion miles on it---that's because the quality of American trucks has always been far better than their cars.
The Tool Guy you must be one of those libteral people calling everyone names... Assuming that someone is a die hard fan for another company is the same thing as stating that somebody who doesn't like Hillary is a Trump supporter... Grow up!
+Thee Tool Guy-You GM fanboys need to start being honest and admit your brand has been low quality and unreliable for decades. There is absolutely no excuse for an engine failure at 19k miles, none whatsoever.
TheLuckyDawg24 It has nothing to do with that, GM is the only brand completely incompetent at making a half decent 4 cylinders. The Ford 2.0 EcoBoost is just as reliable as any other properly built 4 Cylinder, and that's because Ford actually spent the time necessary to engineer and build them properly. Factory Turbocharged Engines need to be overbuilt, as in be prepared to make much more power than they actually do in order to remain reliable for it's entire lifespan. All this engine is is a Turbo thrown onto a tiny little sewing machine that clearly wasn't made to handle Boost.
MaxTheKanuck Ford Ecoboost, reliable? Yeah, the EcoBoost is very reliable, if you look passed the severe carbon build up on the backside of the valves that causes premature valve and valve seat destruction, or the injectors taking a shit under 20,000 miles, or the turbos exploding under 40,000 miles. Look past all that, and yeah. The EcoBoost is extremely reliable!
MaxTheKanuck I know you weren't asking me, but the valve issues are cause by it being direct injected. There isn't fuel being sprayed on the back side of the valves and that causes them to build up carbon. If bits of carbon break off and make it down stream it can screw up the turbo. The newest truck ecoboost engines have 2 injectors per cylinder, one is direct and the other is port. That's what toyota does and it's supposed to fix it. At least that's my understanding.
First off ecoboost engines are turbo gas direct injection engines like a diesel engine but running on gas. Instead of spraying fuel before the valves it is injected directly into the cylinder during compression stroke. So the gas does not clean the valve stem or seat at all. Gases, oil and carbon from the positive crankcase ventilation system will tend to coat the inner runner, valve stem, and valve seat. Oil from a diesel will actually clean the above areas. So a much better PCV system with a catch can is needed or an all aluminum intake with an extra injector. Second many vehicles seem to not have fuel filters anymore but diesel style injectors need very clean fuel so a sub micronic fuel filter is needed. Also not a bad idea for a sub micronic bypass oil filter as well. Third turbo are a high precision device that need to be very well designed, have proper QA/QC and have to treated properly. No running an engine stop (which stops the lubrication and cooling of a 20000 rpm turbo) 10 times a mile in bumper to bumper traffic only to crank boost up to 20 psi.
Poor quality pistons made by the lowest bidder who is required to continue to cut costs year after year. It's the GM way! GM is hard on in their suppliers and unfortunately quality suffers. I bought my wife a new CTS back in 2010 and that car had close to 8k in warranty repair before we even hit 50k miles. Traded that GM shxt box in for a Lexus and haven't had a single issue as of yet.
Austin Dillard Nah, German designers behind them. Only issues on KIA's are lack of craftsmanship (loose plastics, spoilers, etc) and minor mechanical design issues.. Backed by warranty.
The biggest problems were the earlier Kia's. Their name was literally their biggest joke for the longest time (Killed In Action) and it left a sour taste in most Kia owner's mouths. They were extremely un-safe and suffered from tons of mechanical problems. These days they're MUCH better as they're not specifically designed by Kia anymore. Hyundai is in the same boat, they've been getting better but are still not on par with Kia. GM on the other hand is absolutely horrible, GM's were 80% of the vehicles my dad saw in his shop and he specializes in German and Japanese but knows every car like the back of his hand, GM's are hard to work on, always fail and their parts are always extremely expensive. He hates having to ever touch a GM because of how stupid their designs are and how difficult they make everything to replace, they also lose fuel pumps like crazy, no matter the car. The plastic they use in the fuel pumps gets eaten away by the fuel. How Chevy gets away with their commercials saying they've won awards as most reliable car and bashing on other manufaturers is beyond me. Edit: It also doesn't help that most of their technology is stolen and badly ripped off at that. Their original Eco motors were of SAAB and Opel design, the block was all SAAB, extremely solid and well built and then they took the fuel system and electrical designs from Opel. After they co-owned SAAB, they were forcing their shit onto SAAB and taking SAAB's designs, they wanted their cars to be equal and because of this most new SAAB's are terrible for only two reasons, transmission issues and turbo issues especially. After they had what they wanted they forced SAAB into bankruptcy and they were purchased by a Chinese company. The only good thing that came out of the entire ordeal was the Saabaru, a 50/50 mix of SAAB and Subaru engineering that wasn't soiled by GM. So yeah, fuck GM.
What's the point of moving to smaller, high tech engines if they are prone to catastrophic failures like this? Not only is this a blow to the consumer, it is a huge black mark on the brand, and erodes confidence in the technology.
simply because they have no choice. the EPA is making stricter and stricter requirements for fuel efficiency and emissions, and it hit a point of where it's increasing so fast that companies have to half-ass the engineering to get it out on time to try to meet the updated standards. i think it's sitting at 30 MPG combined right about now for minimum (trucks/SUV's get weighted differently, i don't quite understand exactly how though, all i know is they don't really count as much) and in 2025, it has to be 54.5 MPG. i can only imagine the trash that those engines will be :/ we have a 2006 trailblazer going on 200K, still going very strong, we're going to hopefully run it until the wheels come off, as now even 2006 levels of older is becoming better than the modern stuff
Justin Noker Are you seriously blaming the EPA and not the company for using substandard parts and materials? All the other auto companies aren't having these kinds of problems. American cars are terrible because American companies put profit before quality. Next time you go to the gas station look around and see how many American cars vs for foreign car getting gas.
Austin French it was mainly an educated guess as it's the primary reason they're selling the smaller turbo engines here. Other companies (ill use a European one like VW for example) over in Europe, they had strict legislation for a looooong time, some places before the invention of the turbo. As a result, there was no rapidly changing efficiency and emissions requirements we're seeing now in the US under various CAFE and CARB legislation. So for European manufacturers, they have engines that already conform to new standards, so all they have to do is shop them over (main reason a lot of new Chrysler cars are using Fiat engines) while American companies, like Chevy for example, are well known for N/A large displacement motors, like not even any of their I4's were really under 2.0L until CAFE and CARB legislation changed, and as a result they're trying to have the guys used to designing N/A V8's trying to instead design a 1.5L economy turbo motor (which might explain the dumb choice of cast pistons) However, I do get your point, if I were an engineer, even I know the second I hear "turbo" I have to think "Forged" though only the higher ups would allow that decision, as another plausible argument I see towards them using cast is they just have to adapt old equipment meant for casting the pistons, instead of having to completely retool a production line to make the Forged Pistons, which are a slight bit pricier and harder to produce, though we now see how terrible a choice the cast was, so in my mind at least, the retooling would have been worth it.
Well put, sir. That's one of the great things about foreign cars, they all have forged internals even if they are naturally aspirated. They learned that lesson a long time ago. And what sucks regarding American cars is that it's not just because of the turbos, their quality sucks across-the-board. They use so much plastic these days it's ridiculous.
Neighbor has one with 100k dead miss on #1 with 50-60 psi, piston 2 was good, 3/4 160/170 only when giving throttle once you let off compression drops off. Didn't even bother pulling the head told her she needs an engine. Didn't see no damage to top of piston on #1 with my scope so I know it's the ringlands. Sadly I own a 2018 cruze. I'm considering dropping aftermarket pistons in it for this reason. Really isn't that bad of a job. I'm a VW tech 😎
Sick of the obsession with Eco-wank. Governments are making things very difficult, some manufacturers probably don't care as long as it sells. Great videos Daniel.
Zachary Courtois The new Tacoma hasn't exactly lived up to that claim. CR's reliability survey ranked it last and there are a lot of issues being reported on the tacoma forums.
Thank you for this video! It's nice that Chevrolet is standing behind their product and taking the proper precautions in fixing this issue even if it's the entire engine. I will make a mental note on that when I'm in the market for a new car.
Guys, gals n inbetweens, this isn't blow by, this is GM's new line of product in cars called "blow by nos". Its revolutionary it even turns off when your nos blows by the pistons!
Turbo charging, relatively high compression, low octane fuel and poor quality internal parts. The things manufacturers will do to improve their EPA rating by 2 MPG and keep costs down...
Well my Toyota Camry has a bulletproof naturally aspirated 2.5 liter 4 cylinder. It averages 38 on the highway and 28 in the city. The law of deminishing returns for the gasoline engine holds really true. A turbocharged and downsized engine looks good on paper but in reality it an epic fail. What we should’ve done instead of forcing automakers into making needlessly complex internal combustion engines is to have a mandatory road map to phase out brand new cars that run in fossil fuels. Starting with high end and midrange luxury vehicles and trickling as battery technology improves.
More of today's modern "Walmart" grade disposable crap. Sad for Chevy to ruin their reputation putting out absolute junk like this. In the 1970s, the Malibu gained the reputation of being a reliable, bulletproof car. Even the downsized late 70s / early 80s RWD Malibus were reliable little cars, with exception of two years '79 and '80 with some 305 V8s which had poor camshaft metallurgy, but this was still a minor problem compared with this, and didn't show up until much later than 100,000 miles. But get an "Iraqi Taxi" with the 231 V6 and drive it forever, and spend next to nothing on maintenance!
yeah, i was actually looking into GM a bit, and it turns out that there are now quite a few things that weren't GM. back around 2006-2008, they were in a partnership with Fiat, and some signs of this are left (the duramax 2.4L in some cars is actually a fiat design they still hold the rights to) and even the Pontiac Vibe, that was just a redesigned Toyota from when they were in a partnership. then when 2009 happened, all of GM went out of business. what seems to be unknown, is that there are two different GM's. the "old" GM and the "new" GM. the old GM is the GM that was making cars from the company's founding until the crisis of 2009. after 2009, the US government actually gained control of all assets and formed the "new" GM, and the US government owns 60% of the company, Canadian government 20%, and the remaining 20% is divided among shareholders. so basically, the GM that made those great cars and engines, it now ceases to exist.
297,000k miles on 2.4 Honda Accord 2012,you found the right answer. Mine got so bad that I cannot fill the oil more than half because the oil would wet the spark plugs and cause the car to go unto limp mode not past 3k rpm. Time for a new engine I guess 🙁
You wouldn't buy a car built in China, why should you buy an engine designed there? Wikipedia: "The small gasoline engine (SGE) is a family of small-displacement three- and four-cylinder gasoline engines ranging from 1.0 L to 1.5 L, developed by Adam Opel AG, Shanghai Automotive Industry Corporation (SAIC), MG Motor (MG), Shanghai GM (SGM) and the Pan-Asia Technical Automotive Center (PATAC)."
I have a 2007 malibu with a 3.5 v6 and 146k miles on it that I picked up as a work beater car and it runs smooth, I just did a tuneup on it and regular maintenance and have had zero problems. 1.5 is just way too small for a 3400 lb car
G'day Dan that's absolutely discussing considering it's a fairly new car. Blow by I put a catch can on a diesel and it helped stop it. It's no wonder people are buying other makes instead of local, it's the same in Australia that's why Ford and Holden ( GM ) ceased production John
This thing was probably driven like a old person slow and boring like the car itself yet it still blew before the warranty usually cars dont go till after warranty then your screwed
A car will last as long as you maintain it... I've heard from shops they build an engine from scratch and throw it on the dyno right away and do pulls and tune it... I think an engine takes 1-2k miles to Truely Wear all the parts to what they will be at for the life of the engine.
To fix a locked up engine get a sludge hammer and a block of wood and put the wood on the pistons and bang them all the way down then try and starts and make sure no rods or broke and if they are replace them.
My 2015 Ford Focus has oil coming out of the oil fill cap like this Chevy, no lights and it isn't misfiring; and no the cap isn't loose. Idk if it's normal but my old mustang that had 92k miles didn't do it or my new 2016 Fiesta. All of my families Fords have lasted a long time, our family Expedition has 100k with just fluids done and it runs excellent. My uncle has a 2000 Ford F.150 with over 600k miles, a few suspension and exhaust parts but the engine and transmission are original. The only other American vehicle we have owned was a 2012 Jeep Liberty Limited Jet, talk about a piece of crap; transmission was worn out at 40k, piston rings at 49k, and electrical issues at 49k. I gave my sister the Focus to get rid of that awful suv. The Wranglers are good. At least the Pistons didn't melt like the shitty Chevy. :D
Garrett McKie change the O ring on the cap or get a new cap. The engine on the 2012+ focus is extremely reliable. Only been blown by too much boost and lack of oil.
Garrett McKie I'm a Chrysler guy and all of us agree that the patriot/compass is a pile of shit. Very big disgrace and shows a bad reputation to the jeep brand.
I am going to stay away from any of these new small engines with turbo's.Ford is doing it too.I am not convinced of the overall reliability and longevity.I will stick with naturally aspirated.Ford has timing chain issue's with their ecoboost line too.
pontiachotshot I think the reason their pushing these out is because Volkswagen, which have almost always been reliable turbo diesels, cars are forced out of the market. I think Government Motors has something to do with it. Don't say that's the only diesel I had/have, 1999 ford f350 powerstroke, tractors, and cat engines, and cummins. Oh I forgot to mention also that I try to get 03 older vehicles.
Zachary Solomon VW makes a good turbo 4cyl gas or diesel.They have many years of practice under their belt.Ford and GM just cant seem to get their shit together with turbo motors.Newer vehicles are so tempting because they look nice but i call it pretty trash lol.
the reasoning behind the the new turbo small motors is efficiency more power and torque less fuel consumption. lighter car and cooler running motors saves money on both ends of the spectrum for the dealer and the buyer
I got a Subaru legacy with a 3.6 liter Flat 6 and its fast than most turbo charged 1.5 liters on the road. it pushes 275 HP and if I wanted to, I could push 300 HP with a simple Intake and exhaust switch and a recode.
@UCe5fpQpW-aPOW4ZZgbNxOqA No shit, really? You have more than double the displacement and produce more power therefore being faster? Who would have ever guessed? Idiot
That's crazy it's on the new malibu's, I haven't seen that yet, I've done piston sets in cruze's because of chipped ring lands. But it was on the 1.4l turbo.
Being a lube tech at a chevy dealer place, seeing all the new and older chevys i have gotten to see first hand how difficult and cheaply made they are plus the rate at which they have problems from brand new to down the line later on problems. We have 5 or 7 new 2017 malibu cars mostly from rental cars of miss firing and idling rough not even past 10K miles on them. All the problems are the piston heads breaking apart. Not small chips of a good chunk of the edges broken off and slamming against the valves. Still waiting on back order for new engines and it's been 3 months of waiting and still no engines have been shipped to us. The answer GM gave the certifying instructors is that the customers are using cheap gases and it causes the pistons to break apart. But when we asked the master tech the real cause, it's just simply cheap material made to the engine builds. And everything on that shitty 1.5L motor is difficult to remove and install. the turbo itself had me helping a tech aligning it in place just to put 4 bolts on took 45mins because the visibility seeing the holes is 0. everything is cramped together and not much room to work with so everything takes longer to get done.
Junk engine, a mistake during production most likely. At 20,000 miles it shouldn't be happening no matter what. Cold starting really doesn't affect modern engines with modern oil in the slightest yet the internet continues to freak out about it constantly.
In this case, it's said to be a 'melted piston'. The piston crown got so hot it deformed and developed a crack/hole. Because it was driven hard and the engine internals weren't up to it, and/or the engine management system failed to adequately control the combustion conditions.
This isn't just a GM thing, it's the trend towards low displacement turbo engines across the board that is adding stress and complexity to the engines. That all has to do with CAFE standards for MPG, and it's costing consumers. Obvious thing, a lot of "expert" reviewers haven't called this out because they are beholden to the car companies (to get a car for review, they have to be in good with them). It's now becoming quite obvious, Honda recently went to turbos and has a lot of problems. FCA (Dodge/Chrysler) and Toyota have not embraced this trend and are now some of the most reliable cars on the road. Used car resale on turbos is taking a big hit. A V6 Ford Edge for example, has resale 2-3k higher than the turbo 4. As long as you have a warranty (new or certified) it's probably OK, but unless you have a lot of cash sitting around buying a used turbo out of warranty and/or with close to or over 100k miles is very risky IMO.
The more I hear about the engine problems from these high-strung MPG wonders...the more I like my Ford 4.9 inline-6. Stone-age technology, but good for 300K mi.
Leemur2335 the 2.0 and 2.3 ecoboost are based on the Mazda L engines, yes. But to be more specific, Ford is manufacturing these L engines now. Mazda has completely moved on from the old L engine to the new skyactiv engine.
I was talking to a gm technician and he told me he has not seen a single one of these cars come in with that problem. I also have a class mate that works at the service center of a dealership and said he hasn't seen any either
