There has been a high incidence of this model of Toyota Highlander having faulty transmissions. My vehicle had 129,000 when the transmission failed. It was metal shavings in the fluid. I-??m hoping you will put pressure on Toyota to recall or help replace these transmissions. Thank you.

Hello, it seems that my vehicle is having a whirling noise when accelerating at different RPMs. When I researched, it isn-??t an isolated incident because many others online are experiencing the same issue with most of them being told that the transmission must be replaced. And further investigation, I found that the issue could be the trans axle assembly component which can cause issues if not replaced.

Upon acceleration, the engine revved high and a whine sound started once the car (2019 Highlander XLE) approached 25-40 miles per hour. It appears that this is a transmission issue that Toyota was aware about years before selling the 2019 (and later) Highlander and other models (according to consumer complaints online). The car has 92,700 miles on it and is thus out of warranty. It had a recall in 2020 though I do not know exactly what was allegedly fixed. Had Toyota disclosed these serious transmission issues, I would not have purchased the car. My local mechanic has advised that the transmission will need to be replaced at a high cost.

At approximately 85K miles my 2019 Highlander began to exhibit a high pitched -??whirring-?? sound upon accelerating. The noise stops once you take your foot off the gas. I brought the vehicle to my local Toyota dealership to investigate the noise. They concluded that it is the transmission and I would need to replace the entire transmission. There are no warning lights or other indications aside from the sound. Transmission fluid is clear of any shavings or other indicators of an issue. Toyota service stated they could not tell me if or when the transmission might fail, just that it should be replaced. There are multiple reports of similar occurrences on online Toyota forums. There are also recalls for the exact same sound for the 2018 Highlander. I opened a case with Toyota customer service and was told there was nothing they could do to assist.

Transmission failed while driving down the highway almost causing an incident. These transmissions are very unsafe and should be recalled. Toyota refuses to take responsibility for this year Highlander although it is the same 80ua transmission that was recalled in the 2017 and 2018. While Toyota has said this problem has been remedied in the later years it is very false. Please do an investigation on this before people get hurt from accidents if they haven-??t already.
