2016 CHEVROLET MALIBU with 88245.0 miles
Since i bought this car new in 2016 i have had to replace the vcm 4 times. Nothing seemed to fix the problem. The stop/start never worked right. Three times over the last month, after various repairs at the dealership, the car has completely stopped while driving and would not start again. The doors unlocked and locked, vehicle jumped 3 times, all kinds of warning lights and messages on the dash....Then nothing but a dead car in the middle of the road on a sunny dry day. I could've been the cause of accidents while stopped in the roadway and many people could've been seriously injured. The car was fixed the fourth time yesterday and the mechanic took it out to test before returning the vehicle to me. It died on him again and had to be towed back to the service center. Serious safety hazard and the certified gm techs can't figure out what's wrong. P3055 and P3056 are the error codes that come up every time. New battery, new vcm, new wiring harness....Each time the problem got worse until it completely stopped running. No recall and the car is out of warranty so chevy is not willing to help at all.
