I have numerous problems with the engine light coming on. This has been going on for some months now. I have taken the vehicle to the dealership for this problem at least three different times. My engine comes on and stays on for days at a time. The dealership was unable to diagnose the problem. Than for last few months, while I am driving all the gears on my dashboard light up and wont allow me to give the car any gas, and makes a sound like the engine is reving up. This can happen two to five times a day. Now, when I put the car from park to reverse it is a making a long banging noise and jerking the car.
