2020 Toyota Highlander Problems

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.

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

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 were performed on time by certified Toyota technicians. I was repeatedly assured that the vehicle, including the braking system, was operating normally. I request that NHTSA investigate the possible failure of the PCS, forward collision warning, automatic emergency braking/brake assist, and their integration with the braking system.

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.

The contact owns a 2022 Toyota Corolla. The contact stated that while driving at an undisclosed speed, a passing vehicle suddenly attempted to merge lanes and struck the vehicle on the passenger side door at approximately 45 MPH. No warning lights were illuminated. The contact stated that the air bags did not deploy. The contact stated that she sustained pain in her right chest, head, and left arm, and medical attention was sought. A police report was filed. The vehicle was towed to a local tow lot, where it remained for further investigation. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 89,083.

Taken vehicle at least 6 times to dealer (Corwin Toyota), to enquire about the 23v-865 recall, and each time have been told the repair is not available. Most recently asked December 2025.

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 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.

The Pre-Collision System with Pedestrian Detection is a good thing, but there's a problem. It stops the car too abruptly on the highway, leading to rear-end collisions. When you release the brake pedal, the car remains stationary. To get it moving, you need to press the accelerator pedal. There have been four instances of the Pre-Collision System with Pedestrian Detection being activated in the last 12 months. Two of them ended in rear-end collisions. In the other two cases, there were no cars behind.

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

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 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 the toyota page for the claim as well. Ive repeatedly asked the toyota dealership what is going on and I get we are waiting on corporate. I called toyota corporate again today and was told they would get back to me. I told the dealership. I am under medical care and in severe pain. Yes my safety was put at risk. Police and fire department were here the night it happened. They said they don't do a police report on private property. There is an insurance claim through state farm.

While on the freeway vehicle stalled when accelerating and engine stopped, I had to pull over to the side of the road to avoid accident. Turned vehicle back on and started making a whinning noise. Vehicle was taken in and found out the transmission is no good at 89k. Also found out that a lot of people that purchased this vehicle are having the same issue.

Currently having issues for my active recall with no remedy available

The side view mirrors are very shaky at all speeds-- and worse over bumps/and/or at highway speeds. It causes a distraction in the peripheral vision of the driver, and does not provide a reliable, clear image in the mirror while the car is underway. The problem is worse on the driver (left) side, but it exists on both sides. This creates an unsafe condition where vision is not clear in the side mirrors.

1. Climate control system failure to defrost windows during cold weather/winter conditions caused all windows to fog resulting 0 visibility while driving. 2. Occupants including myself, spouse, adult child and toddler grandchild , surrounding vehicles and their occupants were for 5 to 10 minutes exposed to potential multi-car crash, injuries and loss of life. 3. Online research revealed this climate control failure has been experienced by other Toyota owners and the issue has been resolved however not been reported to NHTSA. Two days after the occurrence the vehicle was taken to Bud Clary Toyota, Moses Lake, WA for inspection and repair. Note-without the detailed information from my online research the issue/repair/resolution wasn't determined by the Toyota service shop. 4. There are no warnings when this failure occurs. It happens only when outside temperatures drop below 40 degrees and severity increases with quick drops in temperature. The first occurrence was during first winter of ownership, 2020/2021 and reported to the next servicing dealership, Peterson Toyota, Boise, ID. 5. The repairing dealership required customer pay and advised to follow up with Toyota customer service to report and request reimbursement. Follow up completed later in December 2022, Toyota denied warranty reimbursement however the customer service agent requested and obtained repair reimbursement and recommended reporting and requesting recall status to NHSTA.

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.

Both front struts and bearing plates failed at 75k miles. They were leaking oil before that mileage. Approximate date of failure was 1/5/24. No parts were available until now. Parts were on back-order for upwards of a year for this model of Highlander in the FWD configuration, with 18” wheels. Prematurely failure causes a lot of bouncing in the car, therefore making the vehicle unresponsive to quick steering maneuvers. The bounce also made it so that typical driving within the city is dangerous as the bounce makes the car difficult to control. This is an issue that is documented on Toyota forums for FWD models. An accident has not been caused by this failure as of yet. Vehicle will be repaired soon. Mechanic was finally able to get two factory struts and bearing plates. Each strut is $200 and mounting plates are about $150 each. Parts + labor are expensive, but at least now it will be fixed.

It’s been a known issue that Toyota Highlander has transmission problems under 100k miles from 2016-2021 or later (social media sites confirmed such). My vehicle require a trans axle replacement as well as the struts are leaking oil and my vehicle has less than 62k miles and is only 5 years old. This is being covered under my extended warranty but parts are on back order After doing research many owners complain about a whining noise showing acceleration of vehicle . If left unfixed this leads to transmission gears slipping and eventually needing an entire replacement Some owners also complain about leaky struts. My car has an issue with leaky struts and is being fixed under warranty Some owners say they need an entire new transmission and after that is replaced the rear transaxle goes and needs replacement Toyota is not putting a recall on this but it’s a known issue. Owners are asking to have this put out as a recall by toy. All parts are on back order and takes several months before transmission can be repaired or replaced. This tells me there are hundreds if not thousands of Highlander’s having the same issue This is a Toyota problem and is related to building transmission in the factory..recall the older vehicles and do better in the factory

The rear hatch door will not close or open and just sit there.And dings, you have to manually close it and open it most times and it never fully sucks up and latches fully and it doesnt notify you on the hood display of the car , so when we were driving down the road, we heard loud hissing and road noise coming from the rear and come to find out the rear hatch had never fully closed or latched itself fully.And it hangs up constantly.
