While driving and attempting top accelerate up to speed, the vehicle began to slow and hesitate. It would not properly accelerate. After going a short distance at reduced speed, the vehicle began to shake and hesitate. I was able to make it home (luckily not too far). The wrench symbol on the dash illuminated during this episode as wheel. I checked theowners manual and then called my local dealer who recommended the care be towed to dealer and not driven. This was done the next dayand after a full day of checking the vehicle, the dealer advised they had no idea what the problems was. They released the care to me. The next week the same situation happened several more time and finally, while on the way to dealer, it happened again with the service engine light coming on as well. This time the dealer identified the problem as the throttle body and replaced it at a cost inexcess of $500.
