What 162 owners told NHTSA about the 2023 Toyota Highlander

The driver’s seat lower cushion in my 2023 Toyota Highlander provided inadequate support during normal driving, particularly on the left side of the seat cushion where support for my left leg and hip area appeared insufficient. This caused uneven seating posture, increased discomfort, pressure, and difficulty maintaining a proper driving position during extended periods of driving. The seat became increasingly uncomfortable during prolonged use and caused pain, numbness, and difficulty maintaining a proper driving position. I am a professional driver and spend many hours operating the vehicle. Over time, the lack of support contributed to left-sided sciatica symptoms that required medical evaluation and physical therapy. Medical records document that prolonged sitting in the vehicle aggravated my condition and limited my ability to sit and drive comfortably. An independent upholstery specialist inspected the seat and determined that additional foam had to be added to the driver’s seat lower cushion to improve support and comfort. After the modification, the seat became significantly more comfortable. This indicates that the original seat cushion support may be inadequate. I believe this condition may affect other vehicles of the same model and should be investigated as a potential safety concern because it can affect driver posture, comfort, concentration, and safe vehicle operation during extended driving.

I was involved in a vehicle crash on 7-1-25. I had just pulled out of the gas station and was coming up to a stop sign so I was only going about 8mph I put my foot on the brake and nothing happened. I had my foot all the way down on the brake pedal because I saw a car coming and they were traveling at about 40mph. No automatic braking nothing worked. I had no control. I just prayed that I hope this doesn’t hurt. None of my airbags deployed. My car is now totaled and of course I got the ticket because I did not have control of my vehicle. I strongly believe this has to do with the brakes and how it switches from electric to gas in my hybrid vehicle. Toyota has recalled prior years 2020 to 2022 hybrids for this exact issue. This is a huge safety issue and thankfully I am alive to make this complaint. My husband went to my Toyota dealership where I get all my service and the service manager said yes he has noticed this as a problem that he himself pulled in a Toyota Highlander Hybrid into the garage and had the same thing happen. We have been reading online about others complaining of this same issue.

weather conditions were severe due to a snowstorm, causing ice buildup on the road, low visibility, and slippery pavement. Despite driving cautiously, I lost control of the vehicle, which resulted in going off the road, down an embankment, and crashing into a tree. Immediately after the impact, I called 911 emergency services for assistance. I attempted to exit the vehicle, but the driver’s door was blocked due to the position of the tree. I remained inside the vehicle until a passerby stopped and helped me get out. As a result of the impact, my vehicle sustained significant damage The shocking thing about it all is that the vehicle did not activate the airbags and that is worrying to me because it could have been unfortunate.
