The hid headlights have been blinking together on and off for no reason. started, stopped, moving, sitting in the driveway after shut off waiting for delay lighting to turn off. the loss is momentary. it is more critical on unlit highways and side streets. they blink on and off together. the dealer was unable to repair in a 4 month window. on dry roads, from a stop, starting out at 5-20 mph active traction control turns on and the vehicle stalls. as most stops occur directly prior to intersection this is a very dangerous position to place the driver with a gas peddle that is basically inoperative because the car is in active traction mode and taking over the drive train. dealer was unable to repair over a 4 month period. it might have been related to speed sensors in front wheels but they didn't want to replace them. they made me drive for 2 weeks with a code recorder in order to get them to do any service. *tr
