How to address door handle malfunctions in the 2014 Tesla Model S?

Identify the Issue
 

• Check if the door handle is not extending or retracting properly.
• Observe any unusual sounds when the handle attempts to deploy or retract.
• Try opening and closing the door using both the exterior and interior handles.

Reset the Door Handles
 

• Soft reset the car by holding down both scroll buttons on the steering wheel until the touchscreen turns off and the Tesla "T" logo reappears.
• Test the door handles again after the reset.

Lubricate the Mechanism
 

• If the handle is physically extending but feels stiff, it may require lubrication.
• Use a silicone-based lubricant to lightly spray the moving parts of the handle.
• Operate the handle several times to ensure the lubricant is evenly distributed.

Check for Software Updates
 

• Ensure your Tesla is connected to Wi-Fi.
• Go to 'Controls' → 'Software' to see if there are any pending updates.
• If an update is available, install it and check if it resolves the handle issue.

Examine the Electrical Components
 

• Check the wiring harness connected to the door handle for any visible damage.
• Inspect the door handle’s electrical connector for signs of corrosion or loose connections.
• If you're comfortable doing so, use a multimeter to check for continuity in the wiring.

Replace the Door Handle Module
 

• If the handle mechanism or motor is faulty, you may need to replace the door handle module.
• Purchase the correct replacement part from Tesla or an authorized dealer.
• Remove the interior door panel following a detailed guide or workshop manual.
• Disconnect the old handle module and install the new one, ensuring all connectors are secure.
• Reassemble the door panel and test the new handle.

Consult a Professional
 

• If troubleshooting steps don’t resolve the issue, book an appointment with a Tesla service center.
• Describe the issue in detail so the service technician can diagnose and fix the problem efficiently.
• Consider utilizing Tesla’s mobile service if a visit to the service center is inconvenient.
