Upon acceleration, the vehicle hesitates for 2-3 seconds. this happens on starting off, driving down the road, pulling into traffic. i have had it to the dealer 15-20 times and they can't find the cause. they said it had to fail for at least 5 seconds for it to register on the computer module. it never lasts more than 2-3 seconds and, i consider it 'very dangerous'. dates above are appx. it does it every day. *tr
