Problems with 2010 Acura TL ENGINE AND ENGINE COOLING

Upon keyless ignition, engine continues to race even though gas pedal is not depressed. when applying brakes, engine continues to accelerate, and gas pedal seems to stick even after foot is removed from gas pedal and placed on brake pedal. this happens intermittently without any warning, and speed doesn't seem to come into play. i am afraid to drive this car with this condition. it has happened when i have other people in the car, and now they refuse to drive with me for fear that i am not going to be able to stop. it happened 4 times last thursday evening 9/1/11 on the nj turnpike going north after the toll at 16w going west to route 3, past the meadowlands. traffic was heavy because of an nfl game, and was moving very slowly (no more than 20 miles an hour). when gas pedal was released to reduce speed, the engine was still accelerating, even after the brake was depressed. i drove defensively making sure that i stood well behind the car in front of me to allow enough of distance between it and me to stop. i have owned other acura vehicles and have never experienced this problem. it is hazardous to drive this car - both to the driver and other cars on the road. i had it towed to the dealership where it will soon be checked by the manufacturer. i had recorded this situation when i brought the car in for service on 6/20/11, and the manufacturer could not find anything wrong. in retrospect, it seems that sometime when i was going from one speed to another, the transition to the higher speed was not smooth. note, i never use cruise control, nor the manual shifting. updated 11/17/11 *tr

Engine consumes one (1) quart of oil approximately every 4,000 miles. vehicle was purchased new. if you follow the oil life minder (per the owner's manual) and change the oil when the indicator lights up (typically around 7,000 miles) the engine oil is well below the normal dipstick operating range. *tr
