My check engine light came on, I took my vehicle to Ken Ganley Chevrolet because that is where I purchased it. They claim they have no record I bought it there and at first refused service. I provided my loan documents that state I purchased it. Tim was in the service department, I brought the car in and he had it looked at. He said the issue is the turbocharger, which is a known issue with this year/make/model that GM knows about. The repair was under warranty, completed and the car returned to me. Less than 2 weeks later the check engine light came on and the diagnostic gave the same error. I took it back to the dealership and I got 3 different answers. One person told me it was an exhaust issue that was causing the turbo to overheat (the car is kicking out excessive amounts of carbon monoxide), the second person told me there was no issue and they weren't sure why the check engine light went off, the third person said it seemed like the exhaust and the overheating was a safety issue and it shouldn't be driven. They ultimately refused the repair and said bring it back if it gets worse. I called GM corporate to report the dealership and ask for an actual repair. They told me to take it to another dealership to be looked at. Multiple other dealerships have refused because the case is open with the original dealership. That Ken Ganley Chevrolet dealer is refusing to acknowledge a repair is needed. The car is continuing to kick out excessive carbon monoxide and smells like burning when driving. The engine chugs and doesn't get up to full speed. I requested goodwill reimbursement for part of the car from GM for failure to service and an unsafe vehicle and they have offered no solution because other dealers won't give a second opinion. The car is not safe to drive and is not being repaired.

Car smoking under the hood not even a month after getting repairs done to it for the same issue of coolant loss. Replaced engine oil cooler, coolant housing, and turbo. Car started smoking again less than a month later and mechanic baffled at what it may be this time for there is no warning lights illuminated to point to the problem. The vehicle has had its regular maintenance on time.

Engine oil cooler leaking with no dash lights causing burning plastic fumes only when sitting at an idle to enter car cabin causing passengers to feel unwell at times. With no warning lights for specific leaks or overheating warnings caused high repair bills at the shop. Also, probably causing engines to malfunction earlier than normal since the only sign is the smell of something burning when at an idle and no other warning signs that would be cause of concern to a mechanic or owner. This would only happen if the recirculating outdoor air.

The indicator for the vehicle overheating illuminated as I checked. I noticed that the engine coolant was low so I brought a bottle to top it off however, I noticed once parking in front of my home that I had a puddle of the fluid on the ground.

Car was overheating and the temperature light never came on. There is no dashboard temperature gauge. I first noticed my driver side AC was blowing hot. I was told it needed Freon it was refilled but kept happening. It wasn’t until I was driving and my car said “engine overheating going into idle” that I pulled over and discovered I was out of coolant, which was just topped off a few days before. I ended up having to replace the entire cooling system, radiator, hoses, turbo hoses, fan, and was told I needed to replace the header. I replaced all that and then the turbo went out and a piston snapped off inside the engine and had to replace the entire engine. I feel like this could have all been prevented had there been a dashboard temperature gauge or had the temperature light come on sooner. I had no clue the car was running hot beyond my AC blowing hot and by then it was too late.
