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.
