“We were going down the highway in our brand new Grand Highlander yesterday (3500 miles, 3 months old) and it was like a bomb had gone off. The panoramic sunroof exploded up and out. Glass started falling on my daughter whom was in the middle seat. My husband had to quickly pull off the highway to safety. I have never experienced anything like this and it was extremely scary. Obviously there is a defect that needs to be addressed.”
NHTSA complaint #11718364, filed 2026-02“My 2026 Toyota Grand Highlander exhibits abnormal fluttering/vibration of the hood at speeds above approximately 25 mph. I have identified that this is the same defect documented in Toyota's own Technical Service Bulletin T-SB-0111-24 (issued December 4, 2024), which addresses this condition on 2024 model year Grand Highlander and Grand Highlander Hybrid vehicles, with the same complaint widely reported by 2025 model year owners as well. …”
NHTSA complaint #11752112, filed 2026-07“About two months after purchasing my new 2026 Toyota Grand Highlander Hybrid, I noticed the air conditioning had stopped cooling. I did not notice any impact, so I do not know exactly when the damage occurred. I drive normally on public roads and do not go off road. The vehicle had approximately 7000 miles when the problem was found. There were no warning lights or messages. The only symptom was the AC blowing warm air, which I first noticed around September 25, 2026. …”

NHTSA complaint #11736903, filed 2026-05“My 2026 Toyota Grand Highlander Platinum has an issue that is commonly referred to as cabin boom . It occurs at approximately 30mph going over bumps or rough patches in the road. When it occurs it creates a droning noise that amplifies the bump or rough surface you drove over and also creates a cabin pressure similar to flying on an airplane. This issue has caused significant ear pressure and headaches from driving my brand new vehicle. As a chronic migraine sufferer, this is unacceptable when you commute 25 miles to and from work. …”
