| Description of the problem | Continuous issues with traction control system almost daily. Any time vehicle veers towards the right anti-slip indicator light, alarm sounds and abs system activates. This happens almost daily, on dry roads, going downhill or on a curve, even while switching lanes now. This happens above 20 mph. Driving becomes stressful and worry-some when alarm begins to sound and dash light come on. Fear of losing control becomes great, fear for your passengers safety as well as other drivers safety becomes real. During the past 3 months there have been 5 separate incidents in which the vehicle has lost acceleration, pulls steering in one direction and sudden break lock occurs. 2 of which took place on the freeway on ramp at a speed of 35mph, 1 driving downhill, slightly towards the right, at a speed if 20mph and the last 2 while switching lanes, 35 mph. Vehicle began losing power and slowing instead of increasing speed. There are many complaints regarding this issue with many drivers in many areas. Why isn't this being investigated? |
