Component: TIRES
Southeast Toyota Distributors, LLC (SET) is recalling certain 2021-2024 Highlander vehicles. The 20-inch accessory tires with an insufficient load rating for the vehicle's Gross Axle Weight Rating (GAWR) were installed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims."
Rear lift gate doesn't fully open or close sometimes. I have to manually assist in opening or closing after trying the key fob, inside push button and rear switch above the license plate. I have attempted to reset the height adjustment thinking it would fix it, with no success. I have made sure that the gasket is in place, lubricated the struts and tried opening a closing with the car running and again without success. I'm asking this be investigated due to my concern that this is going to be a safety issue if it doesn't open after an accident, to exit the vehicle if needed. Thank you.
The vehicle experienced a transmission failure at approximately 62,000 miles, which required a transmission replacement. Toyota replaced the transmission with a rebuilt transmission. Immediately after the repair, the vehicle began experiencing multiple issues that were not present prior to the repair. The vehicle initially would not reverse, and the battery was drained shortly after the repair was completed. Following the repair, the vehicle has continued to experience ongoing electrical malfunctions, including dashboard warning lights, system alerts, and dash lights flashing during remote start. The vehicle has also developed a rattling noise underneath the vehicle. The exact failed component has not been clearly identified. The dealership has provided changing diagnoses and has not provided written diagnostic documentation despite requests. The vehicle has been inspected by the dealership multiple times; however, the issues have not been resolved. During a recent diagnostic, the dealership stated that the catalytic converter is now the issue, but this does not address the ongoing electrical problems. These issues raise safety concerns due to unpredictable vehicle behavior and potential failure of critical systems while driving. Warning lights and system errors began appearing after the transmission repair and have continued since that time. The vehicle is available for inspection upon request.

A whining noise was observed at around 78k miles. Brought to the dealer and they indicated parts in the transmission are failing and it requires replacement. They said this has been happening more frequently on 2021 Highlanders (also see T-SB-0008-21). It's also a well-documented issue online. My contact with Toyota was that they did not intend to cover any repairs as the vehicle is out of warranty, even though it's not an isolated issue. They would not disclose how many vehicles have reported this issue. I believe it has reached safety recall-level.
The contact owns a 2021 Toyota Highlander. The contact stated that the vehicle experienced transmission failure while driving. There was an abnormal whining sound coming from the vehicle while accelerating, and the sound increased in volume while driving. There was no warning light illuminated. The vehicle was taken to the local dealer, where it was diagnosed with an internal transmission failure. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 55,803.
The vehicle experiences intermittent power steering malfunction while driving. Warning messages including “Power Steering Malfunction” and “Low Voltage Abnormality” appear, and the steering wheel becomes stiff and difficult to turn. This has occurred multiple times during normal driving conditions, including at low speeds and while turning. When the issue occurs, it requires increased effort to steer, creating a risk of loss of control. Additional warning messages have included AWD malfunction, pre-collision system malfunction, and lane tracing assist malfunction. These alerts appear simultaneously with the steering issue. The problem began shortly after purchase and has continued intermittently. The vehicle has been inspected, but the issue has not been resolved. This condition creates a safety risk, especially when driving with passengers.
Transmission has started to whine, my understanding is this is common for the transmission I have. I have had this verified by 2 different garages. There are no engine lights showing. The noise started around 90K.
My 2021 Toyota Highlander was my first car I purchased that I saved up for and has had a sudden issue accrue with a winning sound out of now where. I took it to the dealer ship and they told me I need a new transmission. My vechile only has 73k miles and I noticed this sound is getting worst and worst. I don’t know what to do so I turned to the internet and I was blow away to see how many people have this same issue with the same year and it’s been happing to so many people. I am a father of a special needs child and I sport my family on my own I can not afford to replace this and they won’t do anything for me. I beg anyone that reads this to please help us out cause this is not fair they we pay our hard earned money to get hit with this unexpected issues that they obviously know about but want do anything cause it will ruin there rep.
Upon inspection at my local Toyota dealership, the UA80F 8-speed transmission on my 2021 Toyota Highlander has a known whining noise attributed to a failed transmission pump. The whining noise occurs when the car accelerates from 0 to around 50 miles per hour. When it gets to highway speeds, there is no noise. Anyone in the car can be put at risk if the transmission stops functioning on the roadways, and we're left stranded or we're suddenly blocking traffic. This issue is a known issue according to T-SB-0008-21, and there are many people online who seemed to have encountered this issue even beyond the warranty limits of 5 years/60,000 miles. Even my local AAMCO tells me that this is a dreaded and known issue of past customers. This issue first appeared around the 60,000 miles of distance traveled. There is no warning for this problem. You just have to be fortunate enough to discover the noise before the warranty deadlines. I discovered the noise at around 58,000 miles around June 2025, but I didn't know it was an issue back then. Had I known about this, I would've still qualified for the warranty. This noise has been reproduced and confirmed by my local Toyota dealership, and they're quoting me $11,506.53 to fix this issue. Other 3rd party transmission shops are quoting me ~$6,000. I'm frankly frustrated that Toyota did not issue a recall for this known issue that I did not cause. I wanted to drive this car for life, but I'm unsure what to do now. Either pay an exorbitant amount of money or sell it.
Transmission failure @110,000miles and a $9000.00 replacement cost. Service advisor at Toyota Dealership indicated they have seen other similar failures on this Highlander Platinum Model at their dealership but unit is out of warranty by a few thousand miles
My 2021 Toyota Highlander is experiencing a transmission issue causing a high pitched whining. It has the problematic UA80F. Toyota has declined to remedy the problem even with it being a known issue.
2021 Toyota Highlander xse all-wheel drive model. Transmission failure: unusual sounds started just after 60,000 miles. Transmission began to whine mid-70,000 miles. Repair costs $8,000. Transmission business recommends rebuilding the Transmissions due to poor design and known issues.
During acceleration above 25 mph a noticeable whining sound is heard from the transmission. When not acceleration the sound goes away. The vehicle only has 72300 miles
When slowing down to stop and the brake is depressed, multiple occasions where the brakes don’t catch. The car jerks forward and I am unable to engage the brakes. I have ended up in the middle of an intersection due to this. It happens frequently, and Toyota continues to brush me off.
The transmission began making a wheezing sound. The dealership looked at the vehicle and determined it needed a new transmission. This is a known problem. Toyota issued a service bulletin on the issue in February 2021. I purchased the vehicle a few months after that. T-SB-0008-21
