My Highlander started making a whining noise while accelerating. Took it to my local dealership and was told I need a new transmission. I have 87,000 miles on it! Total cost = $8,000.

Develop a high-pitched whine, shuddering, or harsh shifting between 25 and 45 mph, which can lead to premature wear or complete failure. Also, On/ Off from no where and stopped in the middle of the road

I was traveling on hwy US1 South about 56-58 mph when I heard what sounded like a gunshot. I immediately slowed down and pulled off the road. As I drove off road on grass/gravel I heard crumbling of glass above on sunroof. The sunroof glass exploded. I called the nonemergency 911 for a police officer to come to the scene. I explained what happened and that there was no rock or large debris. He inspected and suggested I contact my insurance and if they needed a police report it would be in the system.

At 51,000 mile the transmission started making a whining noise. Took it to the dealer and they stated the transmission needs replacement.

My 2020 Toyota Highlander XLE AWD developed a high-pitched whining noise from the drivetrain/transmission area while accelerating. The noise increases under acceleration and stops when the accelerator is released. The noise is not present when the vehicle is in neutral. I brought the vehicle to an authorized Toyota dealership for diagnosis. The dealership confirmed the condition and determined that the transmission requires replacement. The vehicle had only recently exceeded 60,000 miles when the problem was diagnosed. My safety concern is that this appears to be an internal transmission failure occurring at relatively low mileage. Because the transmission is a major drivetrain component necessary to maintain propulsion, I am concerned that continued deterioration could result in loss of propulsion or a more serious transmission failure while the vehicle is being driven. Toyota has reviewed the dealership's diagnosis and has approved supplying a replacement transmission through goodwill assistance. The original transmission has not yet been removed and remains installed in the vehicle. I am reporting this condition because I have identified other complaints involving Toyota Highlanders with similar transmission whining under acceleration and subsequent transmission replacement. I am concerned that this may represent a recurring transmission defect rather than an isolated failure. Because the original transmission is still installed, the vehicle and transmission should current

The transmission started making a whining noise around 69,000 miles that a mechanic said was due to transmission failure. There were no warning lights or messages. I took it to the Toytota dealer who sold it to me new. They inspected it and confirmed that the transmission needed replaced which they did. Online research said these symptoms meant the transmission could fail at any time while driving it which could put passengers and others at risk.

The transmission had a catastrophic failure at 73,000 miles and six years after purchase. There has been a service bulletin issued with known defects on this transmission yet Toyota corporate failed to acknowledge that they installed faulty transmissions in the 2020 Toyota Highlander. The diagnosis was a failed pinion bearing which the dealer diagnosed to replace the transmission at nearly $10,000

Incident: [XXX] Conditions: Clear daylight, dry pavement, normal highway conditions Crash/Injuries: Allstate Claim #[XXX]; several people injured At approximately [XXX], I was driving my 2020 Toyota Highlander Hybrid at about 55 mph in the slow/right lane. The vehicle ahead suddenly made a hard stop. I immediately and forcefully applied the brakes for an emergency stop. My front-seat passenger, [XXX], also saw the danger and yelled for me to stop at the same time. Based on our recollection, approximately five seconds elapsed between his warning and the collision. Despite the rapidly closing distance, the Toyota Pre-Collision System (PCS) did not appear to activate. There was no audible warning/beeping, no flashing red warning, and no “BRAKE!” indicator on the dashboard. This was also observed by [XXX] and [XXX], who was seated in the second row and is particularly attentive to warning signals. The vehicle also did not appear to provide any automatic emergency braking or brake-assist intervention. Despite my immediate and forceful braking, the vehicle did not stop in time and collided with the vehicle ahead, causing significant damage and injuries. The forward-facing sensors and windshield were clean and unobstructed. There were no dashboard warning lights or known system malfunction indicators before the crash. I purchased the Toyota Plus service package after completing the required maintenance during the initial coverage period. All scheduled maintenance and inspections wer

The contact owns a 2020 Toyota Highlander. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed; however, the vehicle failed to stop as intended. The contact stated that the vehicle failed to stop, and the vehicle jerked abnormally. No warning lights were illuminated. The failure was a persistent failure. The vehicle was taken to the dealer. The contact was informed of a software update. The contact was informed that an unknown software update was needed to repair the vehicle. The vehicle was repaired. The contact researched Technical Service Bulletin: 005923, which had a similar failure description. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 15,000.

Coming to a stop or slowing down the vehicle has a spot where it feels like the brakes fail then come back on. Especially if going down a grade. This happens around 15 to 20 mph. Started off a slight moment when you are sure the brakes quit working for just a second. As the vehicle gets older it has brown to be more noticeable.

I was told by oxmoor dealership I had to talk to toyota corporate before I could get my car touched and that I did not need to talk to a lawyer. I called. Prior to the accident, the vehicle had been exhibiting multiple symptoms: an intermittent airbag warning light had illuminated briefly on the dashboard on a few occasions, and the vehicle had begun requiring noticeably longer physical distances to come to a complete stop at traffic signs and lights when not using cruise control. The vehicle was experiencing regular phantom seatbelt warnings—dinging as if a passenger was unbuckled when the seat was completely empty. The phantom seatbelt warnings i didnt think we're a big deal were occurring across multiple seating rows simultaneously in front and back. Directly preceding the crash, while making a turn, the vehicle swerved slightly. When I applied the physical brake pedal, the vehicle did not decelerate normally; instead, it experienced a sudden, abrupt forward acceleration surge into the building. I still haven't gotten my vehicle back or any information on what has been done or when I am getting my car back. I was also charged for an extra day for my rental when I was told to return it on the 16th. I haven't had a rental since then. I keep contacting oxmoor toyota and they said they were waiting on toyota corporate. I haven't had my car for a month. I tried to email. It was returned. My mailbox on my phone has been full of drs and other calls non stop. I texted online on th

I am having fuel pump issues and my VIN was excluded from the recall from Toyota for similar issues. Toyota’s low-pressure fuel pump recall (originally announced Jan 2020, expanded multiple times through Jan 2025) covers vehicles across several model years, where a defective impeller made from inadequate resin material could swell and cause fuel starvation and sudden stalling. Highlander is mentioned as included for selected model years in some recall summaries

We have a 2020 Toyota Highlander with 89K miles that we have owned since it was new. I was informed today to not drive it any long distances from the dealer due to an impending failure of the transmission, creating a large safety issue for me and my family. I understand there are related recalls of the UA80 transmission but none for this particular model; there are countless internet reports of failure. I implore the NHTSA to investigate and protect the motoring public.

I am submitting this complaint regarding a serious braking safety issue with my 2020 Toyota Highlander Hybrid Limited, which currently has approximately 70,000 miles. I brought my vehicle to Victory Toyota of Canton (46352 Michigan Ave, Canton, MI 48188) and reported to Service Manager John Maddison that, at low speeds, the vehicle briefly surges or feels as though it accelerates when I press the brake pedal before it actually begins to slow down. This behavior is alarming and creates the impression that the vehicle is moving forward when I am attempting to stop. This is a serious safety concern that could increase the risk of a crash, particularly in parking lots, stop-and-go traffic, or around pedestrians. The issue has become so concerning that my daughter refuses to drive the vehicle because she no longer feels confident that it will stop properly when she applies the brakes. A driver should never have to question whether a vehicle will respond correctly during normal braking. After researching the problem, I discovered that Toyota has already acknowledged this exact condition by issuing Technical Service Bulletin (TSB) TSB-0059-23. The symptoms described in the TSB closely match the behavior my vehicle is experiencing. I therefore requested that the dealership inspect the vehicle and perform the repair outlined in the bulletin. Instead of addressing what appears to be a known braking-related issue, the dealership informed me that I must first pay a $190 diagnostic fee be

While driving on a 75 MPH highway, the lower bumper cover, windscreen, and interior wheel well components spontaneously detached from the vehicle and got stuck under the car. There were no warming lamps, messages, or other symptoms; the vehicle was driving fine before the detachment. The vehicle has never been in a collision and had no visible damage to the bumper prior to the incident. The detachment was very quick and could have caused an accident, as it was quite physically jarring; additionally, the components got between the vehicle and the highway which caused them to smoke/burn as I tried to quickly slow and pull into the shoulder. A prior recall (#23TB12 / 23TA12) was for a very similar situation. The dealership had allegedly performed the recall fix in March 2025. When I took the vehicle back to the dealership, they said this was independent of the recall. The dealership is unwilling to cover the repair, as they have said that the bumper shows signs of impact. The vehicle bumper has never been impacted. The dealer said there were very minor stress cracks in the paint; when I asked if these could have been from the bumper cover rapidly detaching, they said it was possible but would still not cover the repair.

I pushed the brake and swerved and the car kept going and a greater speed and surged into a house.

Toyota Highlander UA-80 transmission failed prematurely at 63,017 miles (just beyond warranty) due to KNOWN CRITICAL manufacturing defect as per technical advisory T-SB-0160-18 putting me and my family at risk for sudden catastrophic failure on the highway.

The transmission can suddenly fail even at very early mileages. This is almost certainly related to T-SB-0008-21 that has defined a narrow number of transmissions though it appears to affect many more than outlined. This could cause sudden failure while operating the vehicle at any point in time and potentially lead to a crash without much if any warning. Toyota Brand Engagement is denying any assistance due to external service history from a prior owner rather than addressing the failed part outlined in the TSB. Failure reasoning cannot be provided from the dealership as Toyota does not allow the dealer technicians to open the transmission and instead mandate a full replacement.

Transmission stalls in situations where speed is needed. For example when merging into traffic all of a sudden no power then when gear finally engages there a huge thump and feels like being hit from behind.

I know there is a recall for my 2020 Highlander. My VIN isn't listed. The front bumper is coming off and can't be pushed back in.
