When I was under warranty I was pretty vigilant about having any issue I read about or identified fixed since I knew it would be covered. However, if I had to pay out of pocket for the repairs, I would pass on many of the repairs I had done. Ultimately, none of the issues I had prevented me from driving the vehicle but a lot of them decreased my enjoyment of the vehicle.
I had a 2018 LR RWD and the repairs done under warranty that I can remember included:
- Replaced front headlights due to moisture
- Replace taillights due to moisture
- Resealed trunk lid when it filled with water after a rainstorm
- Replaced glovebox after it would open randomly while driving
- Front upper control arms squeaking while driving - replace 3X times!
- Replace charge port door due to getting stuck
- Frunk latch replaced due to not working correctly (required multiple attempts to close)
- Replaced both front door check hinges for clicking when opening door
- Replaced side mirror triangles due to them sticking out causing lots of wind noise
- Replaced temperature sensors that caused heat to not work effectively
- Many, many, many rattles and creaks (front dash, seatbelt adjusters, rear seat, rear deck, wheel wells)
Again, I spent a lot of time at the service center getting these annoying issues fixed but it was an early model and none of these things caused me to be stranded.
On my 2022 Model Y, I have one small rattle from the rear that I need to fix but it feels WAY more solid and I don't feel compelled to take it into the SC.
If you care about having a perfect car, warranty coverage might be really important. If you're less particular than me then maybe it won't matter very much unless you have an expensive HVAC or CPU repair that are more critical to your use of the vehicle.
