2020 Toyota Highlander complaints

This is in reference to a 2020 Toyota Highlander. The Air Conditioner is not functional. Upon inspection by a mechanic, and $300 of freon wasted, it was determined that the lines that carry the AC to the rear of the vehicle are defective. Freon immediately drains. We have a case open with Toyota. The Toytota Case Manager acknowledged that the lines are a known issue, however at this time there is no replacement part available to fix the issue. The initial exchange with Toyota in early June resulted in a response that the part ETA was expected for early July. They have delayed twice since, to Late July, and now the status is pending with an ETA of late August but "subject to change." The vehicle is not drivable with the heat of Summer months; at times the internal temperature of the car is well over 100 degrees. I would anticipate people that live in southern year round hot climates with this issue can't drive it at all. My primary concern is having no AC is a safety issue for passengers, including children and an elderly family member [XXX]) for which I am a caretaker, and pets. Toyota did not respond to a request to provide a rental vehicle until the part is available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN

The transmission has gone out. We noticed a whining noise which prompted getting the vehicle inspected which led to the diagnosis. The vehicle is at the dealership and cannot be driven as driving it will void the warranty. The were no warning messages just the whining noise at about 30-40 mph. We were told it was good that we caught it as the car could have broken down at any time which could have been a safety risk if it had all of a sudden stopped in traffic. We have researched and found that others have had the same issue. The transmission is on back order with no set arrival date.

This vehicle was purchased new. Early in our ownership we ( my wife and I ) occasionally notice that the brakes momentarily release when they are applied for just a second causing us to increase braking which results in the brakes working again. This usually happens when slowing to make a turn at slow speeds. It doesn’t happen all the time but has persisted throughout the four years we have owned the car. We have continued to document this issue with the dealers service department in hopes a service bulletin would be issued with a fix. They have driven the car and done computer diagnostic checks to no avail. Just wonder if anyone else has had this issue and whether anything can be done to fix it ?

On numerous occasions when applying the brakes on my vehicle there is a very noticeable "surge" when the vehicle slows to a near stop. It feels like there is a momentary loss of braking before the brakes re-engage. I have had the vehicle since new and it seems like the problem has become more noticeable over time. I have lost some confidence in the safety performance of the vehicle due to this dangerous issue.

The vehicle continues to place excessive wear on the right rear tire despite the auto dealership service department stating there is nothing wrong with the vehicle. My tires have been replaced 4 times with 89,000 miles on the vehicle. The dealership service department is not willing to look into it any further and states everything is normal despite something clearly wearing this particular tire every 20-25,000 miles.

We were driving at around 70 mph on lane #3 on [XXX] near Auburn CA at around [XXX] on [XXX] with 2 passengers and some baggage in the trunk. No baggage were on the roof rack. Traffic was light and no vehicle was directly ahead of us at the time. Weather was cloudy. Suddenly we heard a loud bang above us, like a gun going off. I opened the sunroof cover and found the sunroof glass shattered. After exiting the freeway and parking, we found only the sunroof glass was damaged. The glass was shattered but still intact. There was no damage to the roof or roof racks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

My 2020 Highlander LTD hit 70K and 3yr mark; all of a sudden my Nav won't search while driving and I cannot dictate a response to a msg. Other forums suggest, reset the DCM by disconnecting the battery for a minimum of 30 minutes. This can be problematic. NO hands free driving capability.

The car is barely 3 years old with 74000 miles to it. The is a humming noise coming from the transmission which the dealer said I may want to replace it. It’s not cheap to do so and I don’t expect it to happen to a new car.

On more than 50 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/stop light 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 took it to the dealership on 9/2023 and was told it was not a problem that could be replicated and it has happened several times since then.

See attached document from complainant

Was following a truck that was pulling a utility trailer. We had just stopped and started moving again when when he suddenly stopped. I had just sped up maybe going 10 to 15 mph when I applied my brake, the brakes did not engage until after I hit the trailer in front of me and jammed it into truck it was being pulled by.I had front end damage and radiator damage and the car was not drivable. I had noticed previous to this that at times at low speeds the brakes would not engage and would need to be double tapped to get them to engage. Could go weeks without it happening or could happen multiple times in a day. No consistency to the issue.

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.

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.

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.

Random loss of braking feeling and jolting forward when stopping due to regenerative braking letting off. Happened randomly since purchase. Happens around 20mph mark

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

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.

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.

The manufacturer was made aware of the failure. The approximate failure mileage is 36,009.

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.

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.

Front strut leaking fluid. Needs replacement. Seals worn out below 36,000 miles.

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.
