The transmission (power train) in this vehicle shows symptoms of a known defect in Toyota's UA80 8-speed. Since approximately (Aug 2026/~70k mileage), it has produced shining/grinding noised at increasing speed. these symptoms match failure patterns described in Toyota's own Tech Service Bulletin for transmission, which have led to documented cases of sudden power loss, gear slippage, and complete failure in other owners of this and related models. I have not yet experienced complete loss of propulsion, but given the documented failure patterns, there is a foreseeable risk this could occur without warning while driving, including traffic or while merging, creating a safety hazard. I took the vehicle to Toyota of Manchester, NH dealership on [XXX] and requested repair given the known TSB coverage. Toyota denied repair assistance, citing lack of dealer service records, despite transmission fluid being a lifetime-fill component unrelated to this failure mode. I am filing this proactively due to the documented risk of sudden failure, and because Toyota denied to address a known, symptomatic defect before it progresses and declined to take responsibility for the repairs or repair assistance for this defect.

My Wife drove to work yesterday with no issues. After her shift she stops at the local gas station by her job, she puts the car in park but the car continues to roll forward( as if it was in neutral). Applies the brake and puts the E-brake on(car is now stationary). Puts in some gas, turn car back on, puts in drive and the car is makes a grinding like noise. We get the car towed home, jack it up, drain the fluid. The color of the fluid was darkish but still had a reddish tone to it, very slight sparkle look to it..didn’t see or feel any metal shavings to it.. highly confused on what failed for the transmission to be like that. Haven’t gotten it to the shop yet but a lot of research is showing something internal. No leaks, maintenance has always been serviced on time.

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.

I have captain seats in the middle. Driver side seat has 4 bolts that secure it to the vehicle floor. The front two bolts were ready to fall out. Caused a squeak that only my wife could hear due to my hearing impairment. I tightened that bolts and the squeak is gone. Pretty serious issue if only 2 of the 4 bolts holding the seat in place are tight.

Faulty transmission with no solution for a fix. Transmission makes grinding noise while driving. Dealership cannot fix the problem knowing that there is an issue with the 8 speed transmission. They recommend replacement with a salvage transmission out of pocket.

There is a “squeak” type noise that sounds like fluid or air is being forced through a crack when the brakes are applied. It is intermittent as brakes remain applied, however it happens every time the brakes are applied and lasts until they are released. The local Toyota dealer diagnosed it as a failed brake master cylinder. After repair, the same noise continues. The dealers “master technician” was able to hear and reproduce the noise, but claim that it is from pressure building to help breaking. The young “master technician” stated that he works feel safe in the vehicle, but they don’t know why it’s making that sound. The sound began 1 year after I purchased the vehicle (I bought it v used in 2022). Warning lamps flashed very briefly indicating something about brakes, although it was difficult to read, as it happened very quickly and has not happened since.

My rear drivers side seat was not properly bolted down. I have been hearing a squeak for the past few years, that only went away when my child was sitting in the seat. We thought it was the car seat squeaking, but recently removed it since our child had grown big enough to no longer need it. I finally inspected the seat and noticed that the seat was moving when I put pressure on it. I took off the covers to the bolts on the front and noticed that I could literally remove them with my had. There was about a 1/16 to 1/8 inch of play in the seat. This is scary that my child has been riding in the unsafe seat for who knows how long. I do have videos of how loose they were, I could spin the washer freely.
