Here’s what you can do if you suspect an issue with the shifter bezel:

Stay Calm and Pull Over

Find a safe spot to pull over if you notice any warning lights or messages on your dashboard. Inspect your gear shifter for visible faults.

Look For Recalls and Technical Service Bulletins (TSBs)

Look for TSBs related to your vehicle’s year, make, and model on the National Highway Traffic Administration (NHTSA) website. 

TSBs provide information on known issues and possible solutions. Check if your Jeep is part of any recalls.

Verify Warranty Coverage

If your vehicle is still under factory warranty, contact your dealership to confirm whether the repairs needed for the shifter bezel issue are covered.

Follow Jeep’s Recommendations

Jeep’s service bulletin says replacing the shifter bezel and wiring can resolve the problem. 

If your vehicle is under recall for specific fault codes (U1465-00 and P1C86-1D), contacting a local dealer may lead to a free fix.

Get the Right Parts

Auxiliary Battery Failure

If you’re facing strange issues with your Jeep, such as the “Service Shifter” warning, it may be due to a dead auxiliary battery. This can lead to various electrical malfunctions.

If faced with persistent issues, request a comprehensive check of connectors and grounding points.

Dealerships should perform thorough troubleshooting and diagnostics to identify and rectify connector or grounding-related problems.

Can Bus Connection Block

The green can bus connection block behind the glove box has been known to cause CEL multiple warning lights and power steering loss.

Check this connection block for any signs of wear or poor connection. Replace it if necessary, as it’s a quick and affordable fix that can prevent recurring issues.

Electrical problems can be complicated, and a systematic approach is crucial. Work closely with authorized dealerships and mechanics to address each concern identified in your Jeep.
