Frequently Asked Questions

What is the first thing to check when the check engine light comes on for a 2024 Jeep Wrangler?

• Check the gas cap — a loose or damaged cap often triggers an EVAP code and is an easy, immediate fix.
• Look for obvious fluid leaks, smoking, or unusual noises; these signs require immediate professional inspection.
• Note any drivability changes (stalling, misfire, reduced power) and avoid driving if the vehicle behaves abnormally.
• If covered by warranty, remember repairs must be performed at a certified dealership to preserve coverage and ensure proper documentation.
