I just took delivery of my 2014 Cruze Diesel today, and was digging through the service records he provided me. During the test drive, he mentioned something about a problem with the turbo that was dealt with under warranty, and I found this entry (I'm guessing he just got the terminology confused... didn't seem too keen on the technical aspects of his Cruze- the dealership had him going at $85 every 3 months for an oil change!):

Customer states that vehicle made loud rattle noise on startup at idle, seemed to try to accelerate... could not get vehicle to turn off.

Found excessive oil in charge air cooler causing engine over rev condition. Glow plugs high resistance.


So they replaced 2 glow plugs at 18,xxx miles, and cleaned out the CAC and radiator, and that seemed to fix the issue. Any thoughts on this incident? I don't expect to see any further issues regarding this matter, but being brand new to this motor, I wanted to get your opinion(s).

I am on my original glow plugs at 165K miles and never had any issues like what you mention. I second the notion that the engine oil was overfilled. If it was truly a case of a runaway diesel, I would be a little scared since what basically happens is that the engine will run on its own oil until it has none left. Maybe they found a way to stop it in time. If it's running fine now, you are probably OK but keep an eye on oil consumption. Mine doesn't use any oil in between my 15K mile changes. Also, I suggest going with 4.5 quarts of oil. I never had any issues using 4.75, but it always was a little high on the dipstick when I used 4.75.

How does it run and drive? Any check engine light?

Welcome to the forum and may you have many happy miles in your diesel!

Thanks for the info guys. I hadn't thought of an overfill, but that makes perfect sense. I plan on taking over all the maintenance for this car, and only letting them touch the car if I need warranty work done.

Car runs great- smooth idle, smooth power, great MPG (50+ MPG on a 3 hour loop yesterday), and I even got it up to 110 MPH on the TX backroads. No CEL or anything, either. I'll try to get the oil changed in a few weeks- none of that crappy dealership crap for me, AMSOIL or Mobil 1 are my oils of choice.
