Incident: Apr 2025
Crash: No Fire: No Unknown
Apr 2025 POWER TRAIN There is a whining noise coming from the power train/transmission. It only happens when the accelerator pedal is pressed. We had a couple of mechanics look at it. The transmission oil was changed twice, with the vehicle less than 78,000 miles. Neither mechanic can find any issue with any other item, including the engine. The noise still persists. There are no warning lights on. We have researched the web. Toyota is aware of the problem and has replaced some transmissions still under warranty. They have issues a TSB (TSB008-21) in February 2021, but did not issue a recall or notify owners of a potential problem.
Incident: Mar 2024
Crash: No Fire: No Unknown
Apr 2025 POWER TRAIN The transmission is making a whining noise at 104;368 miles. We own another 2020 Toyota Highlander and it had to have the transmission replaced for the same reason. It is available for inspection. It’s a safety hazard because it’s a bearings in the transmission that’s failing. The transmission will eventually stop working. The issue was confirmed by a Toyota dealer and one of our transmissions has already had to be replaced. Toyota has a service bulletin out for this known problem. There were no warning signs for the transmission noise.

Apr 2025 POWER TRAIN Around 92k miles my transmission started makining a whining noise while driving. Dealership diagnosed a transmission problem and it needed to be replaced. They said eventually the transmission will go bad and stop working, potentially leaving me stranded or causing an accident. Spoke with Toyota HQ who would not offer financial assistance or assist with getting a part. UA80F transmissions are on a nationwide backorder. They also would not acknowledge that there is a problem.

Mar 2025 POWER TRAIN Transmission going out afraid it will come apart or lose power while driving. Toyota dealership told me that we could put new transmission in but it will be the same as the one that is in it and that problem with them has not been corrected and it probably won't hold up long either. Our vehicle only has 71000 miles and we bought it new.

Mar 2025 AIR BAGS There was a safety recall for this airbag issue, and Toyota estimated the remedy can be available in Quarter 3, 2024, however, till date nothing was completed. Toyota failed to resolve this matter in a timely manner. Every time I ask the dealer, they say no remedy yet! This is very unacceptable. This is affecting my personal finance. I need this to be resolved ASAP. Thank you.

Feb 2025 POWER TRAIN Complete transmission and transfer assembly failure at 72,000. Just outside manufacturer warranty. Toyota Dealership and Corporate refused to acknowledge responsibility, stating that the transmission and transfer assembly met warranty requirements, and that they would not entertain assistance.

Crash: No Fire: No Unknown
Feb 2025 POWER TRAIN,ENGINE At 76000 miles my 2020 Highlander water pump began to fail. 20 days after the water pump was replaced at Kings Toyota dealership, the transmission is now failing at 79000 miles. The warranty only covers repairs on each up to 60000 miles. This car has been maintained by the dealership and no engine light ever came on. The water pump was $1200 to repair and I’m being quoted $10K to repair the transmission. I also don’t trust that dealership didn’t accidentally cause the transmission to fail bc they surprisingly have a new transmission in stock the day I came in. If it truly failed today, then Toyota needs to recall this car for safety reasons. It went from fine to not fine in just a few days of driving.
Incident: Feb 2025
Crash: No Fire: No Unknown
Feb 2025 POWER TRAIN The transmission is starting to whine at 108,000 miles. Toyota service told me the only fix is a replacement and they have seen two failures within the same week. They also said this is a known issue with this model year. A Reddit thread shows many owners in the US and Canada with the same issue. If this is resulting in failures of the transmission in operation this is a safety issue and a reasonable recall being a known defect for this line of transmissions. The recommendation from the service department since this vehicle is paid off is to run it to failure.

Feb 2025 SERVICE BRAKES Sensation of loss of braking, especially at low/crawling speeds, when braking on a downhill, or when braking on bumpy road surfaces. Dealer described it as "INCONSISTENT APPLICATION OF BRAKES WITH CONSISTENT PRESSURE ON PEDAL ON LOW SPEEDS". A very noticeable moment between regenerative braking disengaging and traditional brakes engaging. It was a very unsettling feeling when pulling into a garage or parking space, or making a hard stop at highway speeds. Dealer reprogrammed braking computer per Toyota T-SB-0059-23 ("Hybrid Regenerative Brake Transition Feeling Improvement"). It is improved but not perfect and I still notice this unsettling sensation from time to time.

Jan 2025 AIR BAGS Toyota sent a letter in mid-2024 that there was a safety recall for airbag issue with 2020 Toyota Highlander. The letter stated that a remedy would be available by the third quarter of 2024. As of January 21, 2025, they still have not provided a remedy for the serious safety issue. I would like to file a complaint against Toyota for failing to remedy the defect within a reasonable time.

Jan 2025 POWER TRAIN Before hitting 100,000 miles the car started making a whirring/whine noise when accelerating. We mentioned it to the service advisor when taking the car in for an oil change. Initially the advisor said the service technicians took it for a drive and didn’t notice any noise; when we picked up the vehicle asked the advisor to sit in with us to point out the noise to him, he heard and acknowledged there in fact was a whining/whirring noise and said he would inquire about it to the shop foreman. The next day the advisor called me and said the shop foreman stated that noise is a transmission issue.
Incident: May 2024
Crash: No Fire: No Unknown
Jan 2025 POWER TRAIN The transmission started slipping without any warning and then went into neutral while driving and I am not able to drive it anymore. The dealership said the transmission is bad. I see many complaints online about 2020 Toyota Highlander transmissions going bad for no reason. This is a new car only 4.5 years of normal driving and the transmission goes, this is not normal for such a high rated vehicle.

Jan 2025 AIR BAGS I am not reporting any specific incident related to this defect. I am simply complaining to NHTSA that Toyota is taking far too long to provide a remedy for the OCS sensor issue, NHTSA recall number 23V865 (Manufacturer recall number 23TB15). This issue has been ongoing since late in 2023 and it seems that Toyota should have provided a remedy by now.

Jan 2025 STRUCTURE While driving on a highway, with little traffic around, our sunroof exploded, sending shards of glass down. It produced a sound of a gunshot and quite possibly could have resulted in such a distraction to cause a wreck. The vehicle has not been inspected but insurance agents has been contacted. There were no warnings at all.
