Tesla Model S Door Handle Repair

The Tesla Model S had a recurring issue with the door handle especially on the earlier cars which are now increasingly out of warranty. One of two faults typically occur, the first is the handle is not presenting, it stays flush to the door, maybe slightly raised, and maybe you can hear a clunking noise. The second issue is the door handle presents fine, but when you pull the handle it is not unlocking the door.

This guide explains those problems a little more, tells you what parts you need if you want to attempt the repair yourself, point you to some detailed videos on how to do the repairs, and explains the costs v Tesla for a replacement door handle.

Door handle fails to present

The Model S door handles are sprung to close and a small motor with a geared paddle pushes the handle out to present them. The version 1 paddle gear waas unfortunately fairly brittle and could fail with the round part which sit on the spindle breaking resulting in he cog or paddle becoming loose. Depending exactly how it fails it can sometime twist and jam leaving the door handle slightly proud of the bodywork, or it just falls inside the handle mechanism.

Tesla have since revised he part and the revised part number is 1042845-00-B. This part is super cheap from Tesla, less than $2/£2/€2. Before it was understood that Tesla had revised the part, and some still think the Tesla part is too weak, 3rd parties set about creating this part in a stronger form, milling it from stronger metal. They charge up to 40x the price of the Tesla part and while these may indeed be stronger than the Tesla part, the revised part which is in use today rarely fails and so we find it hard to justify spending that much money. One on-line seller is quoting $80 for the part as their version is made out os stainless steel, we just don't believe this is warranted.

As an aside, because the door handle is sprung, you can leave your fingers in the door handle when it starts to close. Your fingers will get lightly pinched but no real harm should occur as its a spring and not motorised mechanism thats pulling the handle shut. People tend to panic when the handle starts to close and pull their fingers out quickly which can pinch the tips and the shock is more than the actual pain.

Door fails to unlock

Tesla Model S doors, in fact all Tesla doors, are opened electro-mechanically. When you pull the door handle to unlock the door you are not mechanically releasing the door, you are actually making the door handle close a micro-switch which then triggers an electronic component to release the door. What can happen is one of the microswitches (highlighted on the picture) or the wiring coming out of it can fail and the signal either doesn't get created or doesn't get transmitted to where its needed.

You can buy a replacement mini replacement wiring loom including microswitches, part 1016009-00-x. The latest version is thought to be E although its worth checking with Tesla service if buying from them to match it with your particular age of door handle as Tesla have revised the mechanism a number of times. Online 3rd party sellers claim the ones they sell are cross compatible as they include an option to splice into the wiring loom if necessary. The wiring loom from Tesla is approx $40/£40/€40 with 3rd party looms costing around $50-$80

As mentioned the doors on Tesla open though an electo-mechanical process. In the even of a complete power failure in the car some doors can not be easily opened. The front doors are generally ok using the interior door handle, but the doors in the rear of the MS require the use of a emergency door release under the seat. The Model X has the emergency release behind a speaker grill and access is not easy. The Model 3 has no emergency release mechanism for the rear doors at the time of writing. Its worth familiarising yourself with how to exit the rear of the car in an emergency.

To repair or to replace?

A repair is not a trivial process as the door needs to be stripped down and the components replaced. There are plenty of videos on youtube talking through the process for this and we'd recommend the Rich Rebuilds videos.

If, having watched the video, you feel its a DIY task you can take on, then take your time. Even if not, you can consider sourcing the components and asking a friendly garage to do the work for you, expect an hour or so labour charge but the total cost should still be less than $300.

Some typical things to remember:

Tesla will charge around $500/£500/€500 for the part and a little under an hour to replace the door handle if you are out of warranty, probably reasonable for a whole new unit but not environmentally friendly. Because of the number of failures some have tried and been successful at forcing Tesla to do this as warranty work even when out of warranty as the part has a design flaw. The success of this depends on how lawyered up you are prepared to get and the consumer law where you are.
