I was driving on nj parkway south at approximately 55mph in the left lane. suddenly the car had no traction and went out of control. i applied brakes to slow it down and tried to bring it under control. the car swerved to the right into the next lane, then turned left onto the shoulder , back onto the highway (second lane from the left) and eventually stopped facing traffic coming south. it had been raining since the previous night, but the rain was light. i took the car to my usually repair shop. they did a system computer scan, resulting in several pages of output which i took to toyota service station. they were not able to interpret the printed scan. they performed their own scan and told me the output did not show anything wrong with the car. the only explanation they could give me was an oil slick or a pebble on the road and emphasized that the traction control works only at less than 5mph. i contacted toyota corporate customer relations desk. they arranged for me to take the car back to the local dealership for further inspection. *tr
