2026 Toyota Grand Highlander

Moon roof exploded while driving on highway. This is most likely due the to temperate glass used for the moon roof. No collision happened, no debris flying from somewhere else hit the glass, there was no cause for it shatter, the glass just exploded almost causing my family to get injured from glass shards falling down. Thankfully the cover was there and the moon roof wasn’t open.

While driving at approximately 20-25 mph, the panoramic sunroof glass of my vehicle suddenly shattered without any warning. There was no impact from road debris, no visible chip, and no prior damage to the glass. The glass appeared to explode outward, creating a loud noise and causing shattered glass to fall inside the vehicle. This created a dangerous situation that could have led to driver distraction or injury. Safety Concern: This incident poses a serious safety risk. Sudden shattering of the sunroof while driving can: Distract the driver and lead to loss of control Cause injury from falling or flying glass Create hazardous driving conditions, especially at highway speeds Dealer Response: I reported the issue to a Toyota dealership, but they denied warranty coverage, stating it was not covered without providing evidence of impact damage. Additional Notes: There was no visible point of impact, which suggests a possible stress fracture or manufacturing defect rather than external damage. Request: I request that NHTSA investigate this issue as a potential defect, as spontaneous sunroof glass failure while driving presents a significant safety hazard.

I purchased this vehicle new from Toyota of madison in Indiana on 3/26/2026. It had 300+ miles on it. Had it for just a week before this warning light came on while idling or driving very slowly..… High Coolant Temp. Pull over in a safe area immediately. My temperature gauge was in the red. I pulled over. Called closest dealership who stated closed for Easter. After several hours of personal researching on the internet of a potential cause , I examined the engine only to find that my Radiator Fan had been UNPLUGGED!! No wonder the engine was overheating. I currently own 4 corollas, one 2025 tundra, and one sienna. I have never had this issue with Toyota. Why was the radiator fan unplugging and Who unplugged this radiator fan and forgot to plug it back?????

When I went to turn the car on last Tuesday (3/24.2026), the entire digital dashboard was black. I tried restarting the car a few times with no resolution. Thankfully, the infotainment screen and heads up display (HUD) were on and working fine. If it was not for the HUD, I would of had no idea what my speed was driving home. However, I was unable to see my gas level or other safety features which is concerning. Once I got the car home about 15 minutes later, we turned the car off and back on and everything was fine. So far, everything has been working normally ever since. I did take a picture of the black screen as you can see for proof. Please reach out if you need more information.

Front windshield cracked on its own. Car was parked in driveway and there was nothing affecting the crack. It cracked on its own. This is brand new car Grand Highlander 2026 and owned for only 1 month. The front windshield shod not crack like that on its own out of nowhere. I read many other reviews from other owners facing the same issues. Most of them mentioning that this has happened because of the poor installation and some mentioning that even after replacing the windshield it has cracked again. Toyota should address this as a recall asap. For a car that costs $60,000.00 and not being able to install a proper front windshield is very sad to hear it from Toyota. That was number one reason I went to buy the Grand Highlander Limited 2026 thinking that there wont be any issues but the stress started already to accumulate. What could be next?

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.
