recklessX Posted September 15 Share Posted September 15 I own a 2021 Model Y. Yesterday, when reversing the vehicle, I struck an object and damaged the left tail light. Today, I was informed at Brooklyn Tesla that I cannot replace simply the left side; I must purchase two and repair both sides due to programming constraints that prevent singular replacement from functioning. What is your opinion? Do you have any suggestions? Thank you. Link to comment Share on other sites More sharing options...
ouzo Posted September 15 Share Posted September 15 The statement is true only if the component has been upgraded, and mismatched taillights are unacceptable. Link to comment Share on other sites More sharing options...
recklessX Posted September 15 Author Share Posted September 15 Does this imply that Tesla should do the upgrade before to sale, or should it occur post-installation? Thank you. Link to comment Share on other sites More sharing options...
MokweleScoop Posted September 15 Share Posted September 15 @ouzo suggests that Tesla may have modified the lights since your vehicle's production, and hence, they no longer own an equivalent light available for purchase. If the new lights interact with the vehicle differently from the originals, the vehicle may be unable to process that information appropriately. Numerous contingencies exist; nevertheless, if the vehicle requires identical versions of the taillights, you might economize by sourcing a pre-owned left light that corresponds to the one you damaged. If a replacement taillight or set of taillights exceeds your deductible, it may be prudent to have insurance cover the expense. Link to comment Share on other sites More sharing options...
ouzo Posted September 15 Share Posted September 15 The probability is equal, at fifty percent for each outcome. Even if it has the newest firmware, there exists a method to update it via Service Mode if it does not. What I intended to convey is that there may have been an upgrade to the hardware inside the light, and the vehicle may not accept two disparate hardware versions (one in each taillight).

recklessX Posted September 15 Author Share Posted September 15 You will not believe it. I have just exited Tesla. They said that both tail lights are necessary (a single unit is insufficient) and the cost for both (left and right) is $3000. I proposed that they repurchase my automobile for the same $3000, but she failed to get my humor. Can somebody provide guidance on what actions to take? Where can I get an aftermarket set (pair) compatible with my car without issues? Thank you. Link to comment Share on other sites More sharing options...
grubscrewster Posted September 15 Share Posted September 15 I own a set of Y rear lights (outer units only) that I had previously placed on my '18 Model 3 because to my aversion to the red turn signals. Significantly below $3000 if you are interested. You will not need the Mdl 3 (3-pin) to Mdl Y (4-pin, if I recall correctly) adaptor harnesses.

recklessX Posted September 15 Author Share Posted September 15 What is the cost of that? What does "3 pin, 4 pin" refer to? I saw tail lights offered on eBay. How can I determine which pin is required? Link to comment Share on other sites More sharing options...
ouzo Posted September 15 Share Posted September 15 Disconnect one of the rear lights and enumerate the pins in the connection. Link to comment Share on other sites More sharing options...
