NHTSA Complaint #11693416 — 2017 TOYOTA HIGHLANDER

The transmission is experiencing harsh and sometimes delayed shifting and sometimes reduction of power. This can result in unpredictability when going from a stop and then crossing traffic. If the transmission fails while I am making an unprotected left turn it pups leave me vulnerable to side impact from on coming traffic. The dealer was able to reproduce the issue when I took it in and quoted me $11k for repair. Toyota is an aware of issues with this specific transmission (UA80) and issued a Service Bulletin for it. My transmission fell within the serial number range for replacement but didn’t pass the third gate for coverage related to a speed sensor issue. That said, there is massive back order on this transmission highlighting a much broader problem with the part. To answer the final question, I never saw a warning light.
