| Description of the problem | When on a curve the traction control engages affecting the brakes and steering of the vehicle. Speed does not seem to matter, it has engaged at 10mph and at 65 mph. Last straw was when it engaged on the straight away on the highway at 65mph in the high speed lane dropping the speed down to 35mph almost causing a serious accident. It's been happening for a couple of months and two independent mechanics were not able to figure out the problem even after running a moving vehicle diagnostic. It went off a total of 18 times in a aproximate 15 minute, three mile drive with the mechanic. After watching many videos, and complaints online, why hasn't something been done on this issue that has been going on for over eight years now? I'm afraid to take this vehicle on the highway anymore!!! |
