When driving over bumps such as small potholes or railroad tracks, sometimes the ABS and low traction lights come on. Usually they go off. Sometimes they don't. only method to turn the lights off are to pull of the road or highway and turn the engine off. Additonally, sometimes when braking over potholes / railroad tracks, the ABS engage and the clicking starts. Fortunately, due to my careful driving, I give myself plenty of room and don't need to press harder to prevent a collision. Also, sometimes with the low traction light coming on, the engine / transmission will rev up and engage the other front tire, which is completely useless when conditions are dry and normal.

While driving 35-40 mph ABS/traction control light came on, slowed down vehicle to 10 mph. At that time vehicle sped up, wheels screeching. With foot on brake, and vehicle spun around and landed in ditch. Consumer tried to get out of ditch, vehicle accelerated again opposite way. Consumer realized he had a flat tire, drove 100-150 feet to find a flat spot to change tire. Vehicle lurched forward, and landed in ditch, had to be towed. Reported this to Pontiac, no response.
