| Sep 2023 | VISIBILITY/WIPER | 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. | Crash: No Fire: No | Unknown |
| Sep 2023 | STRUCTURE,ENGINE | About once or twice a week as I'm slowly braking to make a turn or stop, the car will surge forward. I have to depress the brake harder, and it does stop or keep slowing. I'm very concerned that if this happens as I'm stopping at a cross walk, someone could be hurt. I took it to the dealer who couldn't replicate it, so said it wasn't a safety issue. There are lots of forums that describe this with highlanders. My partner can feel it happen too. I'm not sure if it's the braking system or engine. My guess is engine because it seems to be a power surge. It's inconsistent, and happens in all kinds of weather, hot/cold, dry/wet. No warning lights, or messages. Happens a lot, but I'm using the example of earlier this week. You're welcome to inspect if you want. It is a hybrid and one of my friends said it might be switching systems, but our other car is also a hybrid and doesn't have anything like this happening. | Crash: No Fire: No | Unknown |
| Sep 2023 | SERVICE BRAKES | On several occasions while coming to a stop or slowing down I have experienced a surge forward while applying the brakes. It has happened at stop signs, stop lights, going downhill. I cannot duplicate on demand. Several times it has surged me past a stop sign while I still had my foot on the brake. Also, when the surge happens, I have to push harder on the brake pedal to stop the vehicle. I have had the hub replaced as well as the wheel censer and I still have the problem. I took it to the dealership on 8/15/22 and it has happened several times since then. | Crash: No Fire: No | Unknown |
| Sep 2023 | UNKNOWN OR OTHER,SERVICE BRAKES | Random loss of braking feeling and jolting forward when stopping due to regenerative braking letting off. Happened randomly since purchase. Happens around 20mph mark | Crash: No Fire: No | Unknown |
| Aug 2023 | SERVICE BRAKES | it does occasionally when coming to a complete stop sign to seems to jolt forward . I have taken it to the local Toyota dealer as a safety concern and was told after they analyized the computer data couldn’t find any problem . Yet it seems to keep happening | Crash: No Fire: No | Unknown |
| Aug 2023 | STRUCTURE | Driving at highway speeds of 75 mph (posted speed), front bumper fell off of car. Outside temperature was 107 degrees. Bumper was lodged under car and all insulation peeled off of wheels. Had to pull all parts from under car and around wheel openings and was able to continue to destination. No accident occurred as the result of this as I was able to safely pull over to side of road. | Crash: No Fire: No | Unknown |
| Jul 2023 | VISIBILITY/WIPER | A rock hit my windshield and it got a crack in it several feet long. A few days later a rock hit the other side of my windshield and it cracked there about six inches. | Crash: No Fire: No | Unknown |
| May 2023 | VEHICLE SPEED CONTROL | The contact owns a 2020 Toyota Highlander. The contact stated that after slowing down to come to a stop, the vehicle would inadvertently surged forward. There were no warning lights illuminated. The vehicle was taken to the dealer who was unable to determine the cause of the failure. The vehicle had not been repaired. The failure had since become more frequent. The manufacturer was made aware of the failure. The approximate failure mileage is 36,009. | Crash: No Fire: No | 36,009 |
| May 2023 | SERVICE BRAKES | UNKNOWN. Brakes have temporary failure midway through braking. The pedal feels like it drops and the car ceases to brake. You press down hard quickly, and it takes a second for the car to then brake again. Naturally the car jerks, at time throwing people forward and locking seatbelts. This happens most frequently going downhill, and happens at a variety of different speeds. Dealership says there is no issue. It happens multiple times a week, if not multiple times a day. While I typically drive with adequate space for this failure, I cannot control other drivers. I almost rear ended a person who cut in front of me from the right lane when the braking failure occurred. | Crash: No Fire: No | Unknown |
| May 2023 | SERVICE BRAKES | My car frequently accelerates suddenly when I am actively braking. I will begin braking, start to slow down, then the car will accelerate, jolt forward, then start braking again. This puts me at risk for having an accident at stop lights and any time I should be braking. I have an appointment to take it to the dealer. It does not happen every time I am braking and it is not easily reproducible, however it has started happening more often. I have no warnings. An independent auto shop has looked at it and they believe there is a problem when my car is switching from regenerative to hydraulic braking. | Crash: No Fire: No | Unknown |
| Apr 2023 | SUSPENSION | Front strut leaking fluid. Needs replacement. Seals worn out below 36,000 miles. | Crash: No Fire: No | Unknown |
| Mar 2023 | UNKNOWN OR OTHER | On March 20th while on the freeway my 2020 Toyota Highlander sunroof exploded. Related or not, I had just rolled up my driver's window immediately preceding the explosion. The sound from this was loud and surprising. Thankfully I was able to get to the right lane and exit the freeway. Upon stopping and viewing the sunroof I was surprised to see the remaining glass pushed UP out of the car. I had no warning nor was I in a situation that I would have expected there to be a problem. I have an appointment 3 days after the explosion at the dealer for them to check it out. | Crash: No Fire: No | Unknown |
| Mar 2023 | SERVICE BRAKES,LANE DEPARTURE | When I am using the brakes an a medium rate the vehicle will loose its brakes for a second causing a loss of control on the vehicle. This happens randomly and caused us to almost go off a culvert of a driveway once. It has scared us many times to thinking we were going to hit the car in front of us. It makes my wife sick every time it happens. Smart motors and regional techs from Toyota have looked into this issue and determined this to be a “feeling” and not a safety hazard. This is not the case and needs to be fixed before someone gets hurt. Lane Keeping assist is unusable. When it is turned on it fights with the driver. It will swerve back in forth in its lane and sometimes so bad it feels like the car would roll if it was not turned off and got worse. Every once in a while it will try to take an exit on the highway by itself. Date of incident in questionnaire is approx to the last time it happened. It has happened too many times to count. Vehicle mileage is when we first started really having issues with the brakes. Lane assist is an always thing. | Crash: No Fire: No | Unknown |
| Mar 2023 | SERVICE BRAKES | We purchased the highlander a few days ago from a Toyota dealership. There are currently no recalls that have not been addressed and the car seemed to be in great condition. Driving the last few days there have been times that the brakes just don't function properly. I went online to see if this was an issue that had been reported. I found this description below and it is exactly my experience as well. This site has the other complaints that match my experience. Feeling like you don't have brakes for a few seconds is going to lead to accidents. I have a 2005 Highlander and I am sad I spent so much money and would feel safer driving my old car. It has not been confirmed by a dealer, or inspected, and there are no lights on the vehicle. I don't know where to go for an honest assessment. https://m.carcomplaints.com/Toyota/Highlander/2020/brakes/service_brakes.shtml I have experienced brake issues, on any slight decline where the braking system will let up as if the braking is not working for a moment, and also, a jerk forward once stopped. This will lead to an accident and potentially, a pedestrian getting hurt if not addressed. I took it to the dealer and they stated they could not replicate the issue, therefore, did not run diagnostics on the vehicle and will do nothing else for me. I have great concern this will lead to an accident and after 30 years of driving, I'm having to constantly think of leaving enough room between myself and other cars to avoid an accident, and adequate room for a brake malfunction. I have another 2020 hybrid Toyota that does not have this issue. So, it is not an issue with all hybrids. - Berkley, MI, USA | Crash: No Fire: No | Unknown |
| Feb 2023 | UNKNOWN OR OTHER | The driver side mirror shakes and vibrates while driving. This is distracting and makes it difficult to concentrate on surroundings. This happens at all speeds. My dealership said that it is normal, but I see many other people on forums have similar complaints. The passenger side mirror does not rattle. | Crash: No Fire: No | Unknown |
| Feb 2023 | POWER TRAIN | I pulled my vehicle into the driveway and stopped outside of the garage. I stepped out to fold my mirrors on both sides of the vehicle as the garage is very narrow. I also need to unload my belongings from the rear hatch. I walked around to the Right side mirror, folded it and headed to unload the hatch when the vehicle PULLED ITSELF INTO THE GARAGE; literally! I could not open the doors as they lock and the space is so narrow. The vehicle stopped when it hit the back wall of the garage. I immediately opened the door and turned the vehicle off. The Vehicle sounds an alarm and shows the message "Shift to park" if not in Park. This did not happen. I sat in the car putting my sunglasses away and unplugging my phone before exiting. If I had not put the vehicle in Park, I would have heard and seen the warnings immediately and the car would have moved immediately; not 30-60 seconds after exiting. Note: our driveway is flat | Crash: Yes Fire: No Towed | Unknown |

| Oct 2022 | SERVICE BRAKES | On several occasions the brakes will get very weak and you have to apply normal than normal pressure. There’s a second where it feels like the brakes have failed. All occasions have been on dry flat roads. This last occasion I was turning into a grocery store driveway and in the turn the brakes failed and I had to press hard and turn harder or I would have ran into the car leaving the driveway. It’s not the hybrid system. I’ve owned prior Toyota hybrid and the brakes don’t give out like this. Sometimes it’s less that 5MPh but it’s also done it at 10-15mph. Both times the batteries are not fully charged so there isn’t any reason why the regenerative breaking should be suddenly shutting off causing the breaks to feel soft. | Crash: No Fire: No | Unknown |
