Jeep Renegade check engine and transmission lights on after jump start, unable to shift out of park on Jeep Renegade

Some Jeep Renegade owners report experiencing issues such as check engine and transmission lights illuminating after a jump start, along with being unable to shift out of park. These problems may arise due to low battery voltage, which can affect various vehicle systems and trigger warning lights. Additionally, while jump-starting a dead battery can initiate the vehicle, it may not sustain the necessary voltage levels for the ECU/CANBUS network, leading to ongoing complications. Several users have noted similar experiences, including service transmission warnings and difficulties shifting out of park post-jump start. The transmission warning light may also appear intermittently, signaling potential transmission issues that require prompt attention. It is recommended that owners check battery voltage and seek professional help to diagnose any persistent warning lights and underlying problems. Following proper jump-starting procedures is crucial to avoid further complications, and if issues persist, consulting a qualified mechanic or Jeep dealership for assistance is advisable.
