Reduced Engine Power - Diesel problems

waxahachiejoe

I have a 14 Diesel Cruz. I bought used with 10K miles on it. It has 20K now. The "reduced engine power" warning came on and the turbo stopped working. I took it to the dealer. They said the diesel particulate filter was clogged because the car never completed a "regen" to clean it. The car is supposed to do this on it's own, but never did. Now they are telling me I owe $320 since they had to do a manual regen and couldn't find a problem. Obviously there was a problem, or the car would have regen'ed on it's own. I'm under full warranty and have to pay $320 to have my car fixed. This is crazy. I would understand if I shut off the car while it was trying to do a regen, but I've never had any messages about a regen pop up.

Should have known not to buy a Chevrolet diesel.

You may want to open a case with GM and ask them to look into it.

2017 & 2018 gen2 cruze diesel will do similar things if the emissions system malfunctions or if DEF is not refilled or is degraded. 2017 reduces max speed incrementally over an hour or so from 65, 55, 45... down to 4mph if DEF is not refilled. We all know it's not because of general motors that such excessive software is required on diesel cars now (thanks VW).

Also for gen2 chevy cruze diesel they thankfully added stickshift and heated steering wheel, two crucial features for winter in new england.
So I had to buy one, at least to forestall my inevitable future corvette purchase by a few more years.

so far so good, less than 1000 miles and no 'regens' yet on 2017, and plenty of engine power and TORQUE . 57 mpg on the 120 miles back from dealership... between 45 and 50 in suburban driving since then. not counting a mandatory subtraction of about 2 mpg due to the DEF consumption - i consider DEF to meet the definition of a fuel since the car will mostly stop without it (max speed 4 mph!) . All diesel vehicles need to factor DEF consumption into the mPG numbers, imho.
