    Door handle failures have been an issue for as long as Model S has been in production. There have been several revisions over the years but ultimately they still fail for a number of reasons.

    Gen 1 used a pressure sensor to "sense" when you pulled on the handle grip and these were the first thing to fail.

    Part #'s
    1007372-00-A-G RF Gen 1
    1007373-00-A-G LF Gen 1
    1007374-00-A-G RR Gen 1
    1007375-00-A-G LR Gen 1

    ***Most Gen 1 Handles do not have any part number tags/stickers on them.***** Ribbon cable coming out of module and lack of 3rd microswitch is best way to identify these.



    Gen 2 changed to an additional microswitch instead of pressure sensor. Because the switches are on the moving linkage the stiff wire and brittle insulation tend to break or crack allowing in moisture and breaking the circuit. The Paddle Gear is also made of cast metal and the ears of the gear break off of the shaft and the door handle no longer presents.

    1007372-00-H-L RF New
    1007373-00-H-L LF New
    1007374-00-H-L RR New
    1007375-00-H-L LR New

    1030273-S0-A/B LF Reman
    1030274-S0-A/B RF Reman
    1030275-S0-A/B LR Reman
    1030276-SO-A/B RR Reman


    Gen 2.5 saw a new handle "chassis" but the same design for the microswitches and paddle gear. The only benefit is the handles "chassis" were no longer specific to front or rear doors just specific to Left or Right however modules were still location specific. The door shells themselves physically changed to accommodate the new style handle. (ex. LF handle couldn't be used as a LR even though it would physically bolt up)

    1071881-S0-A RF New
    1071880-S0-A LF New
    1071884-S0-A LR New
    1071885-S0-A RR New

    Gen 3 Cars were made after 7/24/17 deleted the microswitches in favor of a hall effect sensor, separate module, plastic vapor barrier and updated paddle gear design (still cast metal). The module seems to be the weakest link with this design but hasn't been out there long enough to say otherwise.

    1100299-S0-A LF/RR New
    1100300-S0-A RF/RR New

    The overwhelming majority of people fall in the Gen 2.0-2.5 category. For these door handles we have designed a Stainless Steel Machined Paddle Gear replacement and a plug and play replacement microswitch harness. The harness uses a combination of OE Panasonic Switches and Connector/Terminals with a softer more flexible braided wire and silicone insulation.

    The parts are available as individual pieces or as part of a complete kit including, upgraded gear, upgraded switches, door panel clips, vapor barrier retainers, and e-clip to secure the gear on the shaft.

    Provided you have a Version 2 or 2.5 Handle, We also can rebuild your door handle for you if you feel confident enough to remove it from the car but don't want to take it apart any further.

    You can also watch a good video on how to repair the door handle switches with Rich Rebuilds.

    Yes I will get the different part numbers for each generation either later tonight or tomorrow.

    Here is an additional video that shows first hand some of the different revisions of door handles, what goes wrong, and how we designed things not to fail again.

    I just used the EVTuning $149 kit to rebuild my LR door handle assembly with a replacement gear and microswitch assembly. Removing and reinstalling the door handle assembly was a bit frustrating and tedious (I'm not a fan of working on cars, in general) but the rebuild kit was perfect and everything works now. I do have one question for the collective, though: It appears that there's a Tesla part number on the entire door handle assembly (1007375-00-L). Is that assembly available as a single part from Tesla so that the entire assembly can be replaced, eliminating the need to rebuild it?

    Yes the part number you listed is for the complete door handle. However you'll be paying roughly 600$ for that part and you're still going to have the weak gear design and poorly designed microswitch harness. So while the remove and replace might be easier, you'll A) need firmware which you can't do on your own and Tesla won't do for you if you're installing your own part typically and B) you'll end up having a failure at another point in the future. The purpose of the rebuild is to eliminate the failure prone components and ensure you're not going back inside the door again for these issues.

    Ah, good points. After rebuilding the assembly this weekend with your rebuild kit I can honestly say that your components are higher quality than Tesla's. The other three door handles will break before the rebuilt one will, I'm sure.

    Thank you! That's the plan. I just did all 4 as an upgrade of the original Model S that Consumer Reports reviewed back in 2013! Pretty cool to work on a piece of history. Also a nightmare to work on something so old nothing wanted to fit properly... shims everywhere!

    Which category would a 2014 pre-autopilot fall into?

    2.0 door handles. Switches and gears will work on them.
