2021 Toyota Highlander

I am reporting a serious safety defect involving the rear brake system of my 2021 Toyota Highlander, purchased from Penn Toyota (Glen Cove, NY). The dealership represented the vehicle as “Toyota Certified” and indicated that it passed all safety inspections. On November 15, 2025, I discovered that the rear brake rotors and pads were in extremely unsafe condition, showing severe corrosion, deep pitting, uneven pad wear, and structural deterioration. This damage clearly developed over a long period of time and indicates that the vehicle could not have passed a legitimate safety inspection at the time of sale. The rear brakes had to be replaced immediately to prevent potential brake failure. After replacing the rear rotors and pads, the vehicle passed the New York State Inspection on the same day, proving that the previous brake condition was unsafe and improperly inspected. This raises concerns of: Brake safety failure Improper or falsified dealership inspection Risk of reduced stopping power Potential loss of vehicle control I am submitting photos, the repair invoice, and the inspection result that confirmed the brakes were unsafe prior to repair.

Started with a transmission whining. Now is setting check engine light and jerking. Toyota knows there is a manufacturing defect in the UA80 transmission in these vehicles, but continued to sell them even after the released TSB# T-SB-0008-21, and refuses to repair this under warranty. Toyota is the only company offering replacement transmissions and therefore can set there own price to scam consumers. Please help us get a resolution.

The rear hatch of the vehicle started malfunctioning right when the three year manufacture's warranty was expiring on 08/2024 (very convenient). It would only open part way, barely or sometimes not open at all. One instance, my dog's tail got stuck in the hatch and it would not open. I had to force it open and thankfully I am able to do that. January of 2025 I took the car into Will's Toyota in Twin Falls, ID (where I purchased it new) and they told me that my option was to replace the hydraulic struts that were $1000 for the service. I took the car in on 10/23/25 due to the issue getting worse to have them replace the hydraulic struts. The dealership said they've had a lot of cars with the same issue. I just do not understand how a company can sell a car and a major part of the car fail conveniently when the warranty is to expire. Oh and I called Toyota customer service to complain and they said they don't keep track of this kind of thing...

Glass in sunroof exploded, loudly, while driving on interstate, at 65 miles an hour, showering passenger and driver in shards of glass. There was no impact to the sunroof. Just a loud explosion. Heavy traffic at high speed while covered in glass had to make emergency stop. Glass could have easily gotten in our eyes. Thank goodness the two of us were wearing a ball cap and a visor. Would gladly have car available for inspection upon request. We will take pictures.

The sunroof glass on our 2021 Highlander unexplainably shattered on our ride home on 7/20/25 at approximately 12:30PM. Sky was overcast, and the temperature was in the mid 80's. We had just entered the highway and were still accelerating to highway speed. We were not near a pedestrian overpass where a rock could have been tossed from above. Broken glass edges are pointing upward. The sunroof was in the fully closed position and not tilted. Safety would have been at extreme risk if we did not have the inner slide closed. The vehicle has not yet been inspected by the Toyota dealership or insurance.
