The slip indicator light and alarm comes on sporadically, engaging the ABS suddenly and unexpectedly, when we are on completely dry roads. Happens while driving 40-80 mph. And doesn’t matter if I’m going straight or turning.

The contact owns a 2004 Toyota Sienna. The contact stated while the vehicle was parked, the tailgate inadvertently opened, then closed independently. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the tailgate hydraulic struts needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that she noticed that the failure had reoccurred in 30-degree temperatures on two occasions. The dealer and the manufacturer were not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 140,000.

- Traction control engaged at high speed(70 mph on interstate) causing the vehicle to brake abruptly and pull the vehicle to the right. Had I been traveling in the left hand lane, I could have been forced into the right hand lane causing a collusion with another vehicle. Also occurred at lower speed(30 mph on a windy road) causing the same issue as described above, almost causing the vehicle to leave the paved surface. - Mechanic was able to duplicate the issue - Mechanic diagnosed intermittent traction control activation, scanned computer for codes. Yaw rate/steering angle correlation causing false activation ABS/traction. Replaced hub bearing and spindle. Four wheel alignment, including check castor, camber and adjust toe. Performed zero point calibration and reset ABS memory. - Traction control lights up briefly

About a year ago the Vehicle Stability Control warning light along with an audible alarm started coming on intermittently while turning on highways going uphill or downhill in dry weather and with no risk of any tire slipping. At first this only happened at higher speeds 65+mph. Over time, it has occurred more and more frequently and can occur at speeds down to 25 mph. At times, the Anti-lock Braking System is also activated resulting in jerky braking and loss of throttle. When people have been following me too closely, this has almost caused accidents. When these symptoms occur, it is always on a curve (of any degree, even slight curves) and while driving at least 25 mph, and even happens on flat turns now. The weather has always been dry with no risk of tire slippage.
