I have had this 2011 arcadia for less then a month. The dealer I bought it from assured me that the only issue it had was it needed a new a/c condenser. ( permanent codes, p0008, p0332, p0017 ) (pending codes p0161, p0332, p0017 ) ( stored codes, p0332, p0008 ) severe urgency replace timing chains and related components, t chain x1 t chain x1 t chain x2 timing tensioner x1 x1 x1 x1. I havent even been able to drive it and the sold me the car on false pretenses. They wont help me with fixing it, they wont even fix the a/c condenser. Im going through a divorce and I put the only money I had into this car. I dont know what to do.
I took our 2011 GMC Acadia, mileage 80,637, to the dealership on 12/16/2017 because the display showed "service air bag. " the service technician reported that he found dtc b0022 and b0015 stored in sdm, tested circuits, good. He found excessive resistance in both front seat belt anchor pretensions and recommended replacement of both front anchor pretensioners, cpa connectors with leads and reprogram the sdm. Repair estimate of $1,164. 51. Charged $125 to diagnose. It was explained to me that the pretensioners are connected to and communicate with the air bag. In addition, the service technician found the front engine mount weak. Repair estimate of $447. 85. The seat belt pretensioners and "service air bag" appear to be significant safety issues. I contacted GMC on 04/23/2018 to request repair assistance and to inquire if there was a recall, case # 8-4111443314. I was advised that I would have to pay out of pocket.
