| Description of the problem | This has been happening regularly for at least two years: traction control seizes control of car when traveling anywhere from 35-65mph, but it happens most frequently on freeway at about 60mph. The car is usually on a gradual curve but it also happens when the vehicle is traveling on a straightaway. Vehicle becomes difficult to control, steer, accelerate, lights on the dash light up and a terrible noise ensues. One independent mechanic and two toyota dealers have attempted to troubleshoot the problem and have been unsuccessful. When traction control is manually turned off at engine power-on, the lights still light up showing it is attempting to seize control, and in one instance, control was seized despite the system supposedly being shut down. It is terrifying for the driver as well as any passengers. |
