| Dec 2024 | POWER TRAIN | The transmission in my 2020 Highlander XLE needs replacement at 64,000 miles. | Crash: No Fire: No | Unknown |
| Dec 2024 | AIR BAGS | The contact owns a 2020 Toyota Highlander. The contact received notification of NHTSA Campaign Number: 23V865000 (Air Bags); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

| Dec 2024 | AIR BAGS | 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!!!! | Crash: No Fire: No | Unknown |
| Dec 2024 | VEHICLE SPEED CONTROL,BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE | my wife was pulling into a driveway slowly approximately 5 mph when she went to stop the Toyota Highlander sped up to full speed and smash the tree while my wife was depressing the brake. All airbags were deployed and it looks like they are going to total the Toyota Highlander that has all the maintenance records Very lucky to not have somebody seriously injured. | Crash: Yes Fire: No Injuries: 1 Towed Medical attention | Unknown |
| Nov 2024 | STEERING,ELECTRICAL SYSTEM,ENGINE | I was in a school line waiting for my children. 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. | Crash: No Fire: No | Unknown |
| Nov 2024 | VEHICLE SPEED CONTROL,SERVICE BRAKES | 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. | Crash: No Fire: No | Unknown |
| Nov 2024 | STRUCTURE | The contact owns a 2020 Toyota Highlander. The contact stated while driving at approximately 65 MPH, the front lower bumper cover detached from the vehicle, causing debris to scatter onto the highway, while the damaged bumper cover was dragged underneath the vehicle. During the failure, the vehicle sustained excessive front-end damage, and damages to the undercarriage and fender liners. The vehicle was taken to the local dealer who confirmed that the failure was related to NHTSA Campaign Number: 23V720000 (Structure). The contact stated that the vehicle had experienced the failure listed in the recall. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 51,260. | Crash: No Fire: No | 51,260 |
| Nov 2024 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Nov 2024 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |

| Oct 2024 | POWER TRAIN | I own a 2020 Toyota highlander and the car mileage is 68,000 and the dealer told me my transmission is dead and needs to replacement. The cost for replacement is $13,000.00! I’m the first owner of the car and how could a new Toyota car transmission fail at 68,000 miles and the warranty is 5 yrs or 60,000 miles. This issue have to be Toyota manufacture problems and they should have a recall on this and I researched online and a lot of highlander owners have the same problems as me!

| Sep 2024 | POWER TRAIN | With 55k miles on a 2020 Toyota Highlander, we began hearing a whine. On various on-line sources it appears that this is not unusual among late teens to early '20s Highlanders. I brought the vehicle to the dealer (with close to 56k miles) and the dealer decided the transmission needs to be replaced. Even though the dealer service center acknowledges this is an ongoing issue w/the Highlander of this (late teens/early '20s) vintage I'm told its a 1-2mo wait for a transmission repair/replacement. Warranty is 60k miles... I was told be safe and don't go over 60k miles or its possible the warranty might not be honored. While currently operable, a quick internet search indicates, transmission failure often occurs unexpectedly, leaving drivers stranded on the side of the road. This situation can be not only inconvenient but also dangerous. | Crash: No Fire: No | Unknown |
| Sep 2024 | POWER TRAIN | My vehicle is started making a loud whining noise at around 78K miles whenever you accelerate between about 25-60mph. The dealer said that a new transmission is the only thing that would fix it. The cost of the transmission is 8K. The dealer said that Toyota ought to cover it, but I called and their initial answer is that they will not. This part should be recalled, there are multiple people online saying they are experiencing the same exact issue. This is a very expensive problem for this car, and not one that consumers should shoulder at low mileages.

| Aug 2024 | UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | There is an open recall which has not been addressed in a timely manner. The below has been open since OCT 26, 2023. I have been advised that I would be notified when a remedy was available but it's been ten months with no solution. My front bumper detached while I was on the interstate causing damage to the front end of my vehicle. The subject vehicles are equipped with a resin front lower bumper cover assembly, connected with mounting tabs. If there is minor impact to the lower front bumper cover assembly that causes the mounting tabs to detach from the vehicle during normal operation, one or more parts of this assembly could detach, which could become a road hazard, increasing the risk of a crash or injury for other road users. | Crash: No Fire: No | Unknown |
