| Description of the problem | On numerous occasions, (the first incident occurring november 2013 and most recent 6/23/2014), the stability//traction control system suddenly engaged. Most of the incidents occurred while on the freeway with speeds between 50-55 mph, usually on straightaway sections, sometimes during a gentle bank usually toward the right. On all occasions, the roads were dry and the driver was not applying the brakes at the time. Without warning, the brakes suddenly engage causing the van to feel like it was lunging forward and making it difficult to control the vehicle. A series of rapid beeps would occur and the traction sensor would illuminate. The entire episode would last for several seconds. During these episodes, the vehicle is difficult to control and passengers/other drivers are in danger. |
