jeep runs rough in gear not in park or nuetral and when at a stop sign or light, the motor has a shake. the P540 code is on
Patriot shut off while driveing. Restarted after six attempts. Lucky was at low speed. Dealer updated software. No prior warning. No idiot lights came on. Very dangerous!
When i stop it doesn't want to move. If i shut it off for a few minutes and start it back up its ok for a short while, then it happens again.
