| Description of the problem | The vehicle is an optima 2006. 5 model year. When slowing (braking) and then resuming (accelerating) in stop and go traffic, the car frequently goes into a 'neutral' state where it doesn't go forward on acceleration. When the gas pedal is pressed the engine revs up, but the transmission doesn't engage to drive forward. Once the car coasts down to a speed of about 30 mph or less then the transmission will re-engage - at least so far that has been the case. As this is happening i have to keep depressing the gas pedal to know when the drive gear engages. I have been unable to determine exactly what steps need to happen to replicate the problem, although it does occur frequently now. The current mileage is ~55,000 miles. The situation is very frightening and extremely dangerous when in heavy traffic. It's terrifying to be coasting down to a low speed waiting on the transmission to re-engage when vehicles are quickly approaching from the rear. If the transmission doesn't re-engage, the result is likely to be deadly for all passengers in the car. The vehicle has been returned to the dealer for this problem several times and they are unable to replicate it. |
