Three concerns: (1) the engine light is on. mechanics cannot determine why. (2) the car has trouble starting. When I park indoors, the car dsn’t start. The engine turns over several times and the RPM gs all the way up, but the car will not start until the 3rd or 4th try. mechanics cannot determine why. (3) when I pump gas, the fuel pump automatically shuts off even though the gas tank is not full. So I have to hold the pump in place and use the gas gauge to determine when the tank is full. mechanics have seen this problem in other jeeps but haven’t given me a reason why.
