Transmission was slipping and hesitating from 50,000 miles up until it went completely out at 96,956. The day it went out, I pulled out onto the highway and there was no acceleration, it wouldn't move.

Toyota said my vin wasn't covered under the TSB, so my extended warranty paid for most, but not all, of the transmis

TANSMISSION DIED AT 102,000 MILES, 2,000 MILES OVER THE WARRANTY. Toyota said it will pay $6,000 for parts. I HAVE TO PAY TAX AND LABOR. I have been waiting over a MONTH for the parts, while my HIGHLANDER SITS ON THE Toyota DEALER'S LOT IN RIVERHEAD, NY. My wife took the car there, since the "check engine" light had turned on.

The transmission has started making a whining sound just like the cars/transmissions effected buy the TSB from Toyota related to 8-speed auto transmission failures. My dealer said they have seen a lot of them and mine sounds like it, but they claim I'm not part of the TSB allowing for replacement. Toyota has a real problem with the transmissions in 2018 highlanders but they refuse to fix the problem.

Transaxle (Transmission) failure. Whining noise then failed while driving freeway. Towed to dealer/mechanic and confirm failure. There was a whining sound but no engine light warnings prior to complete failure. Toyota put out a TSB for this but was never informed - POL19-04. Toyota needs to expand CSP ZJC coverage to all UA80F/UA80E-equipped vehicles exhibiting symptoms, regardless of VIN range.

On 11/22/2025, We were done shopping and when we tried to open the trunk it made weird squeaky sounds and we tried to close it but it suddenly self destructed. There was a loud noise and it shattered instantly and there was glass everywhere.

Vehicle’s 8 speed transmission started a low pitch whine when pressing the accelerator around 90,000 miles. Transmission has begun shifting roughly since 105,000 miles. Vehicle is outside of Toyota’s manufacture date deadline for T-SB-0008-21 but this issue sounds exactly like what is described in Toyota’s TSB.
