Complaint covers sat oct 9th thru 10-14 2004 radio malfunctioning-1)took vehicle to jonesboro rd GMC dealer and complaint about radio first. Digital display showing one station and playing another. The panel gets very hot . Radio was showing issue at the time. Mark service advisor reached inside vehicle and began to press the buttons. They refused to document my radio problem at the jonesboro dealership. I called back and spoke to mark about documentation. He said he couldn't because the tech didn't see it. I advised him that he did and I asked him why did he push any buttons. At marietta, my truck had radio replaced twice during this week due to malfunction. 2) abs braking failure, normal soft braking, truck will swerve to side and then correct itself, roll forward and then stop. Was told this is normal braking for abs. Was duplicated at dealership but they have tried to minimize problem (team pontiac, GMC jonesboro rd of union city GA) they did document issue 3) emergency brake ) light not working when depressing emergency brake pedal. Illuminated during start of truck however didn't work when depressing pedal . Marietta pontiac GMC repaired issue. Can now depress emergency brake and it will light up . See previous notes, to date, my truck has had since purchase 12/29/2004 1) new battery, headlight bulb , daytime running light bulb , turn signal switch, new radio 1,2,3,4. New O2 sensor, fuel pump, (lost power on interstate) abs issues, my truck just isn't safe. With this consistent abs problem.
Problem-I dont feel safe in my truck-abs brakes is not working properly when coming in contact with a bump in the road or pothole cover at times. On going incident since purchasing the vehicle new with 127 miles. Despite what the dealer service department has told me, this is normal for abs brakes, this is a problem for me. They have either incorrectly documented or did not document at all my complaint. When stopping at a light and the right brake hit a pothole cover or bump in the road, at times, the rt brake will release and the left brake will "brake". The vehicle will jerk on the rt side causing the vehicle to move forward and swerve. As my vehicle comes to a stop, mybrake pedal pushes down to the floor I find myself stopped at an angle. This is as exact as I can get with what happens. This is a persistent problem. I try to avoid objects on the road but cannot see them all. My vehicle has been serviced and they cannot find anything they say except bulletin for cleaning brake sensors. This visit is the only time my problem has been documented. When I picked up my truck the last visit, I advised the service tech I do not want this problem anymore and reexplain the problems. Please be advised on March 20,04, I filed previous complaint at this site and complained about the abs brakes. Please note when I first had my truck oil serviced I complained about the brakes, I was told abs worked this way. The pedal goes down to the floor. I stopped by the dealership 05/24/04 to file a complaint. Tony wrote the problem on scratchpaper, I got a copy I cannot continue to avoid potholes or bumps, especially at night. I will either rearend some one, get injured or lose my life. I dont feel safe in my truck. I had to explain to my daughter about the problem to avoid an accident. She experience the same problem. My vehicle is still under warranty. I need my situation investigated.
