The contact owns a 2004 GMC Yukon. While the vehicle was stationary, water entered the hvac system and caused the blower resister module to corrode. As a result, the wiring harness heated up, which could have potentially caused a fire in the vehicle. The vehicle was not repaired. The manufacturer was not made aware of the issue. The failure mileage was 145,000.
I purchased a 2004 Yukon xl on 10-19-04 and I have had problems with the vehicles air bag system ever since. I have taken my vehicle in on at least 12 occasions, with repeat visits for same problem usually the same day. My car has given off numerous codes which include but are not limited to the following: b0026, b0040, b0041, b0043, b2470, b0229, b3770. I have taken my car to 3 separate dealerships where they have replaced harnesses, wires, connectors etc. None of this seems to have worked. I have for the last 6 months also have had NY horn blowing intermittently. I have called onstar to perform diagnostics on my vehicle and they have told me that the car has numerous codes coming up, and that I should not drive my vehicle until corrected, because the air bag may deploy on its own or it may not deploy if my car is wrecked. This is a very dangerous situation and I do not feel safe in my car, but I do not have any other choice but to drive it because I do not have an extra $40,000 to buy a new one. I have explained all of this to GMC's arbitration department, but they have sent me several letters stating that they are not willing to buy my car back. My family's lives are not replaceable, and I worry every time I get in the vehicle that something will happen, and this is horrible feeling for a mother, whose job is to protect her children. I would also like to say that I feel very sorry for the individual dealerships, because they have all gone out of their way to try and fix these problems, but all have been unsuccessful. It is not the dealerships fault, it is the manufacturer of the vehicle. I truly believe as my kids have said that this vehicle is truly possessed, and in my opinion not fixable.
