| Description of the problem | When driving on a back road under dry conditions, the traction control light will illuminate as well as an auditory warning. The brakes are also applied. This has happened several times now. Many others have had this problem and have been unable to resolve it. This could be dangerous if vehicles are following behind as the brakes are applied forcefully. This usually happens between 30-40 mph on back roads, only on curves. However, the vehicle is going an appropriate speed for the corner, and there is no reason for this system to engage. The vsc warning light had been on, but had turned off as if the problem had fixed itself. The vsc light turned on on december 24th 2015 and turned off on december 26th, 2015. |
