While traveling at a slow speed on a wet road, the driver had difficulty shifting gears. the vehicle began to shake violently and lunged hard to the right (the driver was unable to correct or control). for unknown reasons, the vehicle then accelerated to a high speed and crashed into two trees. the accident might have been initiated by a malfunctioning electronic stability control (esc) system, causing unexpected braking action and pulling to the right. other malfunctioning electronic sensors and/or associated vehicle control modules, known transmission problems (harsh or unexpected transmission shifts: tsb 02-07-30-013e), or suspension components problems (rear axel or wheel hop: tsb 05-04-114-001a) could have been contributing factors. *tr
