What is the most common reason for check engine light on a 2023 Jeep Wrangler 4xe?

  • Common causes include oxygen sensor faults, catalytic converter issues, loose gas caps, or misfires related to ignition or fuel delivery.
  • Because the 2023 Jeep Wrangler 4xe is a hybrid plug-in system, charging and battery-related codes can also trigger the light; our technicians are trained on hybrid diagnostics and OEM procedures.

  • We recommend you schedule service promptly if the light appears and review current service specials to save on maintenance.

What is the first thing to check when the check engine light comes on?

  • Start with the simple checks: ensure the gas cap is tightened properly; in many cases, a loose cap triggers a code that clears after driving.
  • If the light remains, book a diagnostic with our certified technicians; an accurate scan at the dealership identifies the code and recommended fix without guesswork.
