NHTSA Complaint #11502777 — 2021 TESLA MODEL Y

Heatpump failed which caused a lack of cabin heat and in warmer weather would have caused charging issues due to lack of cooling possibly leaving me stranded. This had a warning on screen about loss of cabin conditioning. This happened over a mountain pass and caused the cabin temp to drop to 25F with two kids in car seats. This could be a really bad situation, luckily we had blankets and such to keep warm for the last few hours of the drive. I believe this was caused by an earlier TSB with sensor replacements and a software change done earlier in the life of my car for heatpump issues. This most likely caused wear on the pump and caused it to fail prematurely just out of warranty. The system was replaced by Tesla at significant cost and confirmed metal shavings in the system from the heatpump. I requested to keep the parts and still have them if further investigation is necessary.
