• 12/31/2025· 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.

  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.

  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.

  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.

  NHTSA, I mentioned to the service tech that I did have an error code appeared in my front dashboard display area momentarily and disappeared several times within the last 10 months. I was told that this would be address at this inspection of OCS (Occupant Classification System) sensor appointment. Doesn't this equate to a faulty OCS sensor and requires a replacement regardless of the testing of the sensor results today. If the error code was displayed in the past logically the sensor is failing and should be replaced. Does this make sense!!!!

  The contact's wife owns a 2020 Toyota Highlander. The contact stated while the vehicle was parked, his wife noticed that the front passenger's side carpeting was extremely wet. Upon investigating the failure, both the contact and his wife noticed that the carpeting underneath was extremely soaked. The contact stated that both he and his wife used towels to soak up the water. The vehicle was taken to an independent mechanic where it was diagnosed that the HVAC evaporator drain hose was clogged, which caused water to leak into the front passenger's side of the vehicle. The independent mechanic informed the contact that the failure was related to Toyota Technical Service Bulletin Number: 0080-19 (HVAC Evaporator Drain Hose Clogged Due to Insect Intrusion) and referred the contact to the dealer for the repair. The dealer and the manufacturer were notified of the failure and informed the contact that the repair could not be covered under warranty. The vehicle was not repaired.

I went to hit the gas to move and the car said “maintenance required” and then flashed other warning lights “low power steering fluid and engine light.” Then the car turned off and screens were flashing. I tried to restart the car but the steering column was locked and brake pedal was locked. I checked all fluids and they were full. I had someone jump the car and it turned back on. I figured maybe a bad battery. Had AAA come look at the car and all diagnostic testing was normal. Next day, car does it again in the middle of an intersection.

  When coming to a stop the vehicle will often lurch forward. The lurch is powerful and could easily cause a collision. This problem occurs both when stopping in traffic and pulling into parking spaces. We were told by the dealer that the problem is caused by hybrid cars but we've had hybrid cars before that did not exhibit this behavior. It sounds like the dealership is aware of the problem but Toyota is not addressing it. This issue certainly poses a safety issue, especially for vehicles in front of the affected vehicle when attempting to stop.

  While driving on the freeway in the evening about 10 minutes into the drive, a loud bang was heard like a shotgun and the front portion of the panoramic sunroof had shattered. Small shards of glass entered the cabin but fortunately no one was injured inside the vehicle. No sign of a rock hitting the vehicle or defect in the panoramic had occurred prior to this incidence. It appears to have occurred spontaneously. There was a large hole in the glass with an outward projection like the pressure inside the vehicle somehow blew out the sunroof. The passengers in the vehicle were at risk of being covered in small shards of glass including a small child in a rear facing carseat who was sitting behind the driver's side. The driver and front passenger would have been impacted as well if the glass gave away. This occurred at high speeds on a freeway where if the glass would have fallen inside the cabin could have caused the driver to be covered in glass, injured while driving at high speeds and caused a wreck. The incident was reported to the highway patrol who could not place a formal report because they said it was not a mechanic defect and the Toyota corporate office said that they could not report because it was a glass issue. Insurance has not been informed yet as we are waiting from the local dealership to see if they can assist. There were no warning messenger prior to this problem and it occurred spontaneously.

  Since purchasing this vehicle I began to notice that the fuel gauge is inaccurate. This issue is sporadic. Often after filling the gas tank completely, the gauge will only register as 3/4 full. Like wise, it is inaccurate when the tank gets low, showing that there is 1/4 tank, when in fact it is nearly empty. The "remaining miles" indicator that displays is likewise inaccurate and often the low fuel indicator light comes on when it shouldn't, and doesn't display when it should. I have had it to the deal 4 times now for repair. Initially they told me nothing was wrong, then indicated that a software update was necessary. When that didn't fix it, I returned the vehicle and they indicated an instrument panel sensor chip needed to be replaced. I waited a month for that to happen and it didn't fix the issue. I then opened a trouble incident with Toyota USA and after several weeks received a call back from the dealer indicating this is a known (presumably still developing) issue and has something to do with a faulty gas tank that causes the readings to be inaccurate. The dealer indicated that they know this will require the gas tank to be replaced but that they don't have parts to do this and will contact me at some point in the future. This is a serious safety issue, as it could lead to the vehicle running out of gas while driving, without any indication that the fuel is low. The only way to have any certainty regarding the fuel level is to do a calculation each time you drive based on the estimated fuel economy and # of miles driven since the last fill up.

• 11/13/2025· SERVICE BRAKES

  When braking, and decelerating through 25 to 20 MPH, the brakes temporarily stop functioning. There is a noticeable change in deceleration that can be felt by the driver AND passengers. This almost feels like an acceleration, but we believe it's the brakes briefly stop functioning. The same problem occurs with different drivers so we are confident the problem is mechanical and not operator dependent. We believe this is a brake actuator issue and there may have been a similar problem in earlier model Toyotas.

  Transmission whining around 38mph when accelerator is pressed. Goes away when foot is off pedal. No warning lights are on. I test drove 3 other 2020 - 2021 Highlanders in May before I purchased this one. All 3 of those had a very noticable transmission whine over 20mph. I opted for this Highlander because there were no noticeable issues/sounds. Just this month, I am noticing a more pronounced high pitch whine during acceleration. This certainly sounds like a much wider issue, especially calling around to multiple dealerships confirming they have other 2020-2021 Highlanders in getting transmission replacements (on 3+ months wait times for parts) This is absolutely a safety issue if a transmission fails while driving. There was a technical bulletin for this same issue with certain VINs, but I was told that my VIN fell outside of that range. To answer rest of questions: No confirmation from dealer on the whine, they are all charging $180 to diagnose the issue and I am not paying that. No further inspections by the above groups listed.

  At around 45,000 miles, my 2020 Toyota Highlander started making a whining noise on acceleration. This condition seemed to get worse (whining got louder) I took it to a Toyota dealership and they said there are no codes left by the vehicle but the repair technician knows that this whine is related to a total transmission failure so the recommendation is to replace the transmission at a cost of approximately $8000, Toyota said the vehicle is out of warranty (by 4 months) so they will offer nothing to assist with the repair. Looking on the internet and this website, it is very clear that this is a common issue with this model of vehicle. Dealer said I can drive it but eventually the transmission will fail, leaving me stranded on the roadside.
