NHTSA Complaint #11712131 — 2019 TOYOTA HIGHLANDER

In early January 2026 there was rough/delayed shifting, whining noises, and fluid leaks. Probably linked to the faulty UA80E/F transmission type. The check engine light came on 1/15/26, I took it into a local repair shop. The mechanic flushed and changed the transmission fluid, replaced all of the spark plugs and the serpentine belt. I picked it up on 1/16/26. There was still shuddering, strange sounds (whining/grinding), and hesitation. On 1/20/26 I drove it and the rough/delayed shifting, whining noises, hesitation and burning smell started happening. The car completely broke down on the freeway and wouldn't drive at all. I had to slowly pull over to the shoulder of the freeway and have the car towed to the repair shop. They inspected it and said I need a new transmission, and it cannot be fixed. I believe the next steps are to have it towed to the toyota dealership to have it looked at.
