Front lower and upper bumper covers. While driving the covers become detached from each other placing the vehicle at risk and other drivers at risk as the components will separate from the car potentially causing damage to the vehicle/tires/etc. or other vehicles in proximity to the car. The dealer has acknowledged this is a known issue but indicates they have no solution. The vehicle was purchase from Pat Lobb Toyota of McKinney Texas on 1/22/2024 and delivery taken on 1/23/2024. They indicate that they inspected the vehicle and found no risk. There are no warnings when this is happening.

The sunroof on my 2021 Toyota Highlander spontaneously exploded. I was merging onto a highway but just started to accelerate normally - was going approximately 20-30 mph. The entrance ramp was a merge lane, and there was a semi truck with no load, so intentionally accelerated slowly to allow the truck driver easy access to the highway. The temperature outside was approximately 80 degrees, clear skies, no construction around me. No object from the truck in front flew backwards to hit my Highlander. It sounded like a gunshot, but felt no impact to the Highlander. I slightly opened the sunroof liner, because the loud noise seem to come from directly overhead. I saw that the sunroof was shattered, so quickly closed the sunroof liner to prevent any glass from falling down. I exited the first exit and drove to the dealership. Ironically, I already had an appointment for routine maintenance. When I arrived at the dealer - I saw that an approximate 6" x 2" section of glass was missing, and the rest of the sunroof was completely shattered. There is no visible damage to any other part of the Highlander. The service advisor looked and it looked like the glass looked like it was pushed up, in his words "looked like it was pressure induced from the inside". My friend searched - and found this is a common problem in 2020-2021 Toyota Highlanders.

We purchased 2021 highlander in March 2021. Since the day we experienced some vibration in the driver side mirror and we first notice bad vibrations when we drove above 40 to 50 mph. We never bought this up with Toyota or the dealer untill May 5th 2023. When we created a case with Toyota, they directed us to the dealer. Once we scheduled the service they confirmed the vibration and replaced Part Number:?879400E351. After the replacement we noticed that the vibrations are getting bad even during lower speeds now. The mirror is vibrating during idle and any speed higher than 30/ 40mph. We scheduled another appointment with the dealer and the manager did test drive another highlander 2022 model and confirmed that it is also vibrating. It was surprising to see that all the highlanders have these mirror vibrations. They said eventhough theres is vibration, it'd be considered normal. I rive mostly during night. The driver side mirror is blurry, vibrating and is extremly difficult to drive the car and is scary that the image on the mirror is not steady and create confusions to the driver. Changing lanes or entering to highway is really challenging as the mirros are vibrating too much and extremely hard to concentrate. This may even can cause major accidents as the image is not clear. The vibrations (humps, dips, rumble strips) are even translated to driver side vibrations and is very hard to see. The dealer even agreed to it but said that it-??s a Toyota flaw in design because all Highlanders have this-?? and after talking to them, they said the only way Toyota would even look at this issue or have an engineer take a look in to it is if they get enough complaints or see a pattern. This is why I am reporting this to NHTSA. I want to keep Americans road safe and sound to all my fellow humans. They also said Toyota RAV4 also had these issue and Toyota issued a TSB however there is nothing on Highlander. I humbly request NHTSA to seriously look in to this and assist us.

On Saturday Jan 21, 2023 while driving 70 mph on I75 between Naples and Ft. Lauderdale Florida the lower bumper fell off. We didn't hit anything on the road. I was driving and my wife was in the car and witnessed the incident. We pulled off onto the shoulder of the highway. Our quick response saved not only the lower front bumper from going under the front tires but also avoided a major accident. We had to tie the bumper to the grill and went to the nearest Toyota dealer. He put it up on the lift, showed us how Plastic plugs securing the lower bumper had failed. He secured the bumper with zip ties so we could proceed on our journey.

Recently purchased this Highlander on August 2021. On 11/29/21 at around 8:00 AM, the Check Engine light illuminated resting stop at a red light. Engine still running. Took the vehicle to the dealership at 9:45AM. Vehicle was found to have had misfires as a result of bad gasoline. I have been pumping at the same gas station ever since I bought the vehicle. If it was the bad gas, this issue should have happened sooner. Now, the dealership is telling me to pay for the diagnostic fee which they claimed it was my fault. The vehicle is under warranty. Another non-power/fuel issue that came with the vehicle was a loud wind noise when reaching 40 MPH. The noise is very annoying, like someone whistling into your ear. The dealership is ordering a part to fix this issue. The vehicle is still at the dealership.

About 15 minutes prior to the incident, the interior shade cover was closed beneath the moonroof. Mostly sunny day about 85? F, about 55mph, the moonroof exploded. The sound was that of a shotgun, followed by wind noise and tinkling noises of shattered glass just beyond the shade cover. Upon external examination, 100% of the glass sliding moonroof was shattered, approximately 30% of the glass had departed the vehicle from a forward and central portion of the glass area. The remaining glass was bowed outward. The roof aft of the moonroof displayed 1-3 millimeter length flags of clear coat paint where the glass shards had etched the painted surface and the rear spoiler fairing panel over the aft hatch had gouges in the plastic composition along the upper surface of said fairing. All components on the vehicle were factory installed. Vehicle had 10,000 miles and was in service just over 5 months. There were no indications of an impeding problem. The moonroof was secured with tape and cardboard to prevent shards of glass from departing the vehicle. The dealership body shop estimates repairs at $4319. Safety threat: If shade were open at the time of explosive incident, shards of glass would fall onto driver and passengers, which might create a loss of control from panic (explosion was very loud and disconcerting) glass in facial area (between eyes and sunglasses) or falling into clothing at the neck area and creating a painful bloody situation at highway speeds. Shards of glass departing incident vehicle might reach a following vehicle (motorcyclist) depending upon upward trajectory of glass and forward speed. Might affect vehicles traveling in opposite direction. Driver following incident with window down might be exposed to shards of glass slip streaming into that vehicle.

Vehicle has had excessive wind noise since new. This was brought to the dealership's attention at the 5,000 mile service, and again at the 10,000 mile service. At the 5,000 mile service nothing was checked or done. At the 10,000 mile service the noise level was measured with a decibel meter and was at 79db at 55mph. The service tech then drove another 2021 Toyota Highlander that was on the lot and it registered the same decibel level at the same speed. The service tech said that he heard excessive wind noise, but since it was the same on both cars, there is no defect in our car. According to the CDC, noise above 70db over a prolonged period of time may start to damage hearing. The Toyota service manager said that Toyota's acceptable noise limit is 100db, therefore there is no problem, he is not going to attempt to fix the issue. According to CDC 100db is equivalent to a car horn at 16 feet, and cause hearing loss after 15 minutes. This is a dangerous noise level for the inside of a vehicle with the windows up and radio off.

After leaving my hotel in San Diego in the early dense foggy morning. I pulled over to help a kid who looked like he was just hit by a car or something. I put my 2021 less than 1500 miles at the time Highlander in park. The kid walked up to my rig, I being a single female, cracked down the window, and asked if he was ok. At that point he just opened my driver's door and I started to panic as I thought the door was still locked. I grabbed the door a closed it and tried to lock it but not before he was able to open the back passenger door and get in. I really freaked out. Without thinking I got out of my rig and as he was closing the door I grabbed it and told him no get out. I have NEVER felt so unsafe in my own vehicle before because even in park while I was still in the car the door's were all locked and no stranger's could just walk up an get in. This is a serious life threatening situation. I made a video right after but, this doesn't take videos. Also, there were 3 other witnesses or more and the SDP of CA didn't even come a ask us any information. But, the fire and rescue, and ambulance came for the kid age 16-21, whom I tried to help and was only wearing his underwear. And was bleeding from head to toe. But, he scared the heck out of me as he 2as also at least 5'9-6'. Big kid I know. But, still a kid. And I was still in danger because my door's were not locked and I could not access the SOS. The cover would not open, or I was so scared I couldn't get it to open. Nonetheless, a new system is needed for emergencies just like that. Not all emergencies are about a crash.
