|---|---|---|---|---|
| Jan 2026 | POWER TRAIN | THE TRANSMISSION FAILED SUDDENLY. | Crash: No Fire: No | Unknown |
| Jan 2026 | UNKNOWN OR OTHER | Premature transmission failure. Vehicle had less than 100K miles. Took the vehicle in for an oil change before a long trip. Mentioned a "whine" during acceleration. Told us that the entire transmission would need to be replaced immediately at a cost of over $10,000. Made an appeal to Toyota to help with the cost of replacement and we were denied. | Crash: No Fire: No | Unknown |
| Jan 2026 | POWER TRAIN | Our 2020 Highlander with 45,000 miles started making a whining noise when accelerating. After the Toyota garage looked at it we were told that we needed a full transmission replacement. No warning lights came on alerting of us of problem. We were also told by the service depart that they are not surprised there hasn’t been a recall due to how many transmissions they have replaced on these vehicles and especially this type of transmission. Upon researching this particular issue, It is a wide known issue with class action lawsuits. New transmissions are also only carrying a 1 year warranty. That is hardly a warranty on a costly repair. It will cost us out of pocket $8,000 for a vehicle that is meticulously maintained and with only 44,000 miles. These vehicles are still being sold putting myself, my family and many more Americans as risk. | Crash: No Fire: No | Unknown |
| Jan 2026 | POWER TRAIN | I have experienced ongoing transmission problems, including but not limited to rough shifting, delayed acceleration, jerking while driving, and abnormal noises.

| Dec 2025 | POWER TRAIN | The contact's wife owns a 2020 Toyota Highlander. The contact stated that soon after purchasing a new set of tires, the vehicle made an abnormal rattling sound upon acceleration. The vehicle was taken to a dealer for an oil change and tire rotation, and the contact was informed that no defect was found on the vehicle. As the failure persisted, the vehicle was taken back to the shop, where the tires were purchased. The contact was informed that there was no defect in the tires, and the failure might be related to the differentials of the vehicle.

The failure mileage was approximately 55,000. | Crash: No Fire: No | 55,000 |
| Dec 2025 | SERVICE BRAKES | My 2020 Toyota Highlander Hybrid has a braking issue identified in Toyota Service Bulletin T-SB-0059-23, Hybrid Regenerative Brake Transition Feeling Improvement. When going downhill and applying the brake, the vehicle lurches forward temporarily as the braking system transitions from regenerative to hydraulic braking. The first time my vehicle did this, it was very alarming and I had to take additional measures to slow my vehicle as I was driving downhill. My vehicle frequently demonstrates this problem, however, I did not report it to my local Toyota dealer because I read in an online chat group that it was a characteristic of this vehicle. Although the TSB recommends a Reprogram of the Brake Actuator Assembly Control Module, the repair is only covered under the Toyota Basic Warranty which is in effect for 36 months or 36k miles, whichever occurs first. My vehicle is past the warranty limit, and because I did not report it to my dealer previously, this repair is not covered under the TSB or the Toyota Basic Warranty. Toyota Highlander Hybrid model years 2020-2022 are affected. The Technical Service Bulletin was issued August 29, 2023, so if a 2020 model Highlander Hybrid has this problem, 2020 models would have already passed the warranty limit by the time the TSB was issued and thus would not be covered. This is a safety risk as drivers can lose control of the vehicle when braking, particularly when going downhill. The Warranty should be extended, or this problem should be elevated to a RECALL so that older affected vehicles, or those with higher mileage can be covered under warranty. Drivers should not have to pay for a recognized problem that affects the safety of this vehicle and has been identified in a Technical Service Bulletin. This problem puts drivers at risk of losing control of the vehicle and the problem can be mediated with a software reprogram. T-SB-0059.23 should be elevated to a RECALL, or extended regardless of age or mileage. | Crash: No Fire: No | Unknown |
| Dec 2025 | POWER TRAIN | My 2020 Highlander developed a whining or grinding noise consistent with the Technical Service Bulletin. I took it to a Toyota Dealership for diagnostic and they confirmed the whining and hissing sound. They said it would cost $9,000 to repair. I called Toyota to request a goodwill repair and they denied me. Toyota case number: 251229000423. The car does not feel safe to drive. We worry that at any moment the car could break down with our children inside. The problem was reproduced at a dealer and inspected. There were no warning lamps or messages, just the obvious sound coming from the transmission. | Crash: No Fire: No | Unknown |
| Dec 2025 | POWER TRAIN | Shortly after the powertrain warranty expired, the automatic transmission in my 2020 Toyota Highlander began producing a loud whining/howling noise during normal driving. The noise appears to come from the transmission area and increases with vehicle speed. The issue was not present during the warranty period and began unexpectedly soon after expiration. The abnormal noise raises concerns about internal transmission failure and potential loss of drivability. This condition could pose a safety risk if the transmission were to fail while driving, especially at highway speeds or when merging into traffic. No warning lights or messages were displayed prior to or during the issue. The vehicle was inspected by a Toyota dealer, and the problem was confirmed to be related to the transmission. | Crash: No Fire: No | Unknown |

| Dec 2025 | POWER TRAIN | The vehicle’s automatic transmission (power train) has developed a loud whining/whirring noise under acceleration. This noise increases with engine load and indicates internal mechanical failure. The transmission is still installed in the vehicle and is available for inspection upon request. This issue poses a safety risk because it causes hesitation and unpredictable acceleration behavior while merging or crossing traffic. There is also concern that the transmission could suddenly fail while driving, resulting in loss of propulsion and potentially causing an accident. The problem has been inspected and confirmed by a Toyota dealership, which advised that the entire transmission needs to be replaced at a cost of over $8,000, despite the vehicle having only approximately 77,000 miles. The vehicle has been inspected by a Toyota manufacturer service center. They identified the transmission failure but stated there are no current recall programs covering this specific VIN. No warning lights or error messages were displayed at any time before or during the failure. The first noticeable symptom was the transmission whining/whirring noise during acceleration, which began around 77,000 miles and continues to worsen. | Crash: No Fire: No | Unknown |
| Dec 2025 | POWER TRAIN | Road noise was very loud. I thought it was a bearing and I took it to the shop and found out that the 'transfer box' on the side of the transmission had to be replaced. I was told that not replacing it could lead to major transmission failure. This cost $6000. Mechanic said it's unusual. Upon reading the internet I'm learning that I'm not the only one this and similar problems. | Crash: No Fire: No | Unknown |
