2021 Toyota Highlander owner complaints (15)

• ELECTRICAL SYSTEM,STRUCTURE,UNKNOWN OR OTHER

  The back hatch of the car has issues closing regularly. Nearly half of the time you push the button to shut the back hatch when it is open it will not close and has to be shut manually. Typically, it shuts an inch or two and then beeps at you and when you push the button again nothing happens but beeping. This is an issue because it is very difficult to close. Even as a 6' 200+ lb man who does strength training regularly, shutting the back hatch is difficult to do manually let alone for my much smaller wife. This has let to her having to ask for help from strangers in a parking lot to help close the door which is unsafe, particularly since we have small children. Toyota has acknowledged that this is a known issue and have stated that there is nothing that they can do to fix it. This acknowledgement came when the car was very new and my father was the owner and again just a few months ago when we brought up the issue again with Toyota.

• POWER TRAIN

  Vehicle started making a high pitched noise when accelerating at around 98,000mi. I took the vehicle in for the 100,000mi service at 100,854mi and had them also look at this issue. I was told that there was a failure in the front carrier pinion shafts and they recommended replacing the transaxle assembly and rear main seal for $8,354. The vehicle was certified with a 100,000mi power train warranty, but it was just out of warranty. I discovered that there is a class action lawsuit against Toyota for knowingly installing transmissions in 2017 to present vehicles that were known to fail prematurely.

• POWER TRAIN

  My 2021 Toyota Highlander is experiencing the documented transmission issue impacting vehicles with the UA80E transmission. Our transmission whines and experiences a hesitation or jerks the vehicle. Especially under acceleration. My vehicle was purchased brand new from Toyota. Serviced at a Toyota dealership since purchase.

• UNKNOWN OR OTHER

  Have been having issues with my 2021 highlander power liftgate strut failure. It will not open at times unless you have to repeat pressing the button. It makes a noise that you know it is definitely not working right. This has been going on for three years and the service department keeps telling me it is working fine for right now...

• FORWARD COLLISION AVOIDANCE,LANE DEPARTURE

  2021 Toyota Highlander UA80 transmission failed at 100,000 miles. Codes P2808, P0741. Matches Toyota TSB-0160-18 and T-SB-0008-21. Dealer Alexander Toyota and TMS Brand Engagement denied goodwill. TMS rep stated "TSBs don't matter" despite pending class action Pallaya v Toyota, Case 2:25-cv-10458, which cites these TSBs as proof Toyota knew of defect. Toyota refusing to honor documented defect. Transmission slip/loss of power is safety issue. Request investigation.

• POWER TRAIN

  The transmission is in the whining stage of transmission failure. It has been confirmed by Cumberland Toyota in Cookeville, TN. There were no warning lamps, etc. however Toyota did post a Technical Service Bulletin (TSB) on February 09, 2021 that my vehicle would have transmission issues. My warranty expired the last of April 2026 and I am over the mileage warranty by 800 miles. I recognized the whining on June 21, 2026 and reported to Toyota on June 22, 2026. Toyota knew this transmission was going to fail and most are being reported just outside the 60,000 mile warranty. I have asked for help and assistance from the local dealership as well as corporate, but both have declined to assist.

• POWER TRAIN

  Transmission started to whine and act erratically during driving. These effects put safety of those in the vehicle at risk by causing distractions to whomever was driving the vehicle, taking their focus off driving. The vehicle was taken to the dealer who confirmed the transmission needed to be replaced due to an internal failure. They said they were able to quickly diagnose this problem because "they saw it a lot." There were no warning lamps or messages from the vehicle.

• POWER TRAIN

  After just passing 100K miles, there is now a whirling noise upon acceleration. After taking to an auto repair shop, they narrowed it down to the transmission and said it was a known problem (referenced T-SB-0008-21) and suggested I take it to the dealership. I took to the dealership where a service manager offered to ride with me to confirm and he confirmed the issue was in fact the known problem noted from the technical service bulletin. The Toyota dealership assistant service manager stated that the noise (which he said was coming from a final drive gear bearing) would continue to get progressively worse and that despite being a known issue, there was no remediation available aside from replacing the transmission completely. He said that he saw no reason that I could not continue to drive the car without complications and without the transmission going completely out for at least a couple more years, but that the noise would get progressively louder until you could no longer tolerate the noise level and would need a new transmission at that point (despite it just beginning last week (or my just noticing it), you can hear it over the the radio when at a low to moderate volume). If this is a "known issue," (ie: a defect that is only in some of the cars per the T-SB-0008-21 notice) this does not seem like a reasonable answer to 'just wait until you can't stand the noise level with acceleration and then completely replace your transmission as there is nothing we can do for you' but it was suggested that I could take it to a body shop that would rebuild transmissions and they may could replace that part.

• POWER TRAIN

  Transmission needed! 76,000 miles and Toyota will not address the issue! We have owned Toyotas for 30 some years! Sienna, Avalon, RAV4, Sequoia, and now the Highlander!!!!! There is a massive issue with the transmission across the board in the 2021 and 2022 Highlander and Toyota will not replace.

• POWER TRAIN,ENGINE

  I own a 2021 Toyota Highlander with approximately 127k miles. The vehicle has developed a noticeable whining/whirring noise during acceleration. The noise appears to originate from the drivetrain/transmission area and has become increasingly noticeable over time. The condition occurs every-time during acceleration and is present under normal driving conditions. I am concerned that this may indicate a transmission or drivetrain-related issue that could affect vehicle reliability and safety. I have found reports from other 2021 Toyota Highlander owners describing similar symptoms involving whining noises during acceleration. The vehicle has been inspected by a Toyota dealership. And is certified through Toyota. The vehicles was bought new from the Toyota dealership and has had all service done through Toyota. I am submitting this complaint so NHTSA can evaluate whether this condition is part of a broader pattern affecting similar vehicles as a defect in the original transmission built in the SUV.

• POWER TRAIN

  I own a 2021 Toyota Highlander with approximately 93,000 miles. The vehicle developed transmission symptoms including whining noise. A Toyota dealer diagnosed internal transmission failure and recommended complete transmission replacement at a cost of approximately $9786.31. Toyota declined repair assistance. I am concerned because a transmission failure at this mileage is unexpected and appears similar to other owner complaints involving the 2021 Toyota Highlander transmission.

• POWER TRAIN

  Transmission makes a metallic whining sound when you accelerate. Associated and confirmed to be transmission failure. Vehicle has 65,000 miles on it and failure is considered premature. The specific transmission, UA80, is known to have manufacturing defects that cause this problem

• STRUCTURE

  The front lower bumper detached while driving on the PA turnpike. The vehicle was traveling in the left lane approximately 75 MPH and was bumping on the road until we were able to pull over all the way to the right lane for approximately 1-2 miles. This hanging bumper dragging on the floor causing some damage to upper bumper as well. This was extremely unsafe for everyone in our vehicle and put the safety of all other driver around us at risk of accidents. No warning lights were present before bumper detached. Toyota dealership looked at it and refused to do anything about it, saying that they see damage to upper bumper and that is not part of recall. I told them the damage to upper bumper was caused by lower bumper falling off and being dragged at speeds of 75MPH until we could safely pull over. They stated that the recal only offered a repair kit to lower bumper. I will include a picture of bumper after lower bumper detached and upper bumper still firmly attached. I had no option and had the bumper repaired by a auto body repair shop. This should have been fixed by toyota and i would like to be reimbursed by toyota. There should be punishment to toyota corp for endagering the public and not keeping their word to correct recalls when they are known about. On June 8, 2026 i received a text message from toyota informing me that there was a recall on my vehicle for front bumper detaching. I responded that is exactly what happened to my vehicle. Needless to say they did not respond to that.

• POWER TRAIN

  The transmission in my 2021 Toyota Highlander began producing a whining noise during acceleration between approximately 15-50 mph at around 80,000 miles. The noise stops when the accelerator is released and has progressively become louder. The vehicle was inspected by a Toyota dealership. I was informed that the condition is a known issue affecting some Toyota vehicles, but no repair was offered because the vehicle is outside the 5-year/60,000-mile powertrain warranty. There are currently no warning lights or diagnostic trouble codes. I am concerned that the transmission may fail while driving, resulting in loss of power or propulsion and creating a safety risk for myself and other motorists. The vehicle remains available for inspection.

• POWER TRAIN

  The vehicle transmission has a distinct whine noise as previous models have had. This is a known issue with these transmissions.
