turbo reliability for the new Cruze

dean1 · 10-14-2009, 03:48 PM

I am sending this thread directly to GM engineers. Frankly, I am worried about the determination of GM, to install the 1.4 litre turbo gasoline engine in the new Cruze. It is a well known fact the turbo engines do not have the long term reliability of a conventional engine. Nobody seem to be addressing this issue in any of the threads. My question is whether this engine will be as reliable as a conventional engine? Will it be as reliable as the ecotec 2.2? If so, what steps are GM taking to ascertain this?

They'll do the same QA (or more) as any other vehicle they release. For it's time, the 2.2L wasn't the be-all, end-all of reliability.

In most cases the engine is fine its the turbo that fails. I thought they were going to make the Cruze with a few engines if you want performance get the turbo engine if you want it to last get option 2. Lets face it most people that get the turbo cars get them to run them so they will wear out faster.

Modern turbo engines are a far cry from engines of the past. Most of them have very small turbos to give nice low-end torque without any of the dreaded turbo lag. Also with electronically controlled boost the manufacturers all pull boost as the rpms rise so you will never get full boost at redline which adds a lot of cylinder pressure/heat.

Certainly turbo engines will have a little more maintenance than the average NA engine due to higher cylinder pressures and more heat but most of this will simply come as more consistent oil changes. The under hood heat also tends to make belts and hoses age at twice the normal rate but other than that you should expect a long engine life when properly maintained.

As far as turbos failing that mostly happens when people run them hard and immediately shut them off without a slow cool down period. The heat then tends to "coke" and kills bearings when restarted.

There are plenty of reliable turbo motors. technology has come a long way so they shouldn't eat head gaskets and such. Turbochargers themselves from my experience last well pass 100k miles if they haven't been abused

When you get the bill for GM's backwards timing belt replacement technology, turbo reliability will be the last thing on your mind.

Sorry to jump subject, but

what is "GM's backwards timing belt replacement technology"?

first off, Your GMC does not have a Turbo, and what is this GM's backwards timing belt replacement technology? sound like labor to me.

it is not a problem unless you let some "tuner" play with the ECM

It's coming out with a new car with technology (timing belt) that almost every other manufacturer has gotten away from several years ago.

It's being under a microscope because you were the largest company in the world, and you were mismanaged into bankruptcy. Now you come out with a new car not only with ancient technology that domestic buyers haven't been used to paying for since Opel was here.

So your service advisor gets to inform Mr. Customer who's giving GM one final chance, "Let me tell you the service convenience built into your Cruze! There's 100,000 mile coolant, lifetime transmission fluid, no more of those pesky 3000 mile oil changes but....I almost forgot about that 100k timing belt change that will set you back about a grand. Have a nice day!"

I was thinking the Ecotec line all had timing chains

Only the Family II Ecotecs have a chain.
