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.
