Transmission whining, hard shifting on 1 and 2 and 3 JP Pauley toyota claim my 2018 Highlander is not part or TBD and neew transmission is required to fix issue quote $7300. to repair current mileage 156K

My 2018 Toyota Highlander with 143k miles has poor acceleration shift lag and a whining noise from transmission. Dealer diagnosed and found transmission is failing and in need of replacement. They quoted $9624.00 to replace and the part is on backorder and could take months to get. Toyota customer assistance has declined any assistance with the repair even though they have a extended warranty program and a customer support program for the same year vehicle and with the exact same symptoms offering complete repair coverage regardless of mileage but declined my saying I'm not eligible due to the production date of my vehicle. I feel this vehicle is now unsafe to drive due to the possibility of complete transmission failure possibly at any time on the roadway.

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. It was flashing "traction control turned off" "check engine visit dealer" "check awd system" and the check engine light was on as well as the orange triangle with explanation point. Toyota said my vin wasn't covered under the TSB, so my extended warranty paid for most, but not all, of the transmisson and parts. They put in a new transmission but the new one does the same thing. It hesitates and slips with currently only 10,000 miles on the new one.

Transmission starting making a wining noise, and was told it will fail. Toyota is well aware of this issue.

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. After the inspection, We were afraid to take it out of the parking lot. Code P275614 torque converter presure control solenoid; faulty transmission problem. Recommended a new transmision for $11,303 plus tax. Many class action suits are being filed about TRANSMISSION PROBLEMS in HIGHLANDERS!

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.

This occurred at 11:45 PM and we were stranded for 1.5 hours waiting for a tow truck. 3)

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.
