The weather seal on the moonroof is coming off the moon roof surround and this is causing water and air to leak inside the passenger cabin.

I was driving down [XXX] at approximately [XXX] this morning and heard a loud bang, then an air sound like window not fully closed, then heard crumbling glass falling into Sunroof shade. Initially I thought I had a tire blowout or someone on the access road fired a pistol. When I stopped and took a picture of the sunroof I saw the front sunroof glass bulging upward and the whole window was cracked with glass lying in the sunroof shade. If I had the sunroof shade open the glass would have been all over my head. I reported the incident to Orr Toyota in Hot Springs, ar. and they informed me that Toyota claims that something impacted the window. There was no impact to the window as it would have caused the window to bulge inward if that occurred. They evidently ignored my original picture so I don't see how they could make a determination of impact after I'd driven the vehicle more than 50 miles to get to their location (The event occurred in Bryant, ar).

Bought the vehicle in October 2025 everything was going fine. I went away for a few days came back and the A/C was not working. I took it to the dealership where I purchased it and was told outside influence and they refused to repair unless I pay $1900. I have bumper to bumper coverage for 5 years, My point is for a SUV that is costing over $50,000. If the condenser is such a sensitive piece of equipment it shouldn't not be placed in front of the vehicle unprotected. This is a design flaw because the SUV is made to be driven on the highway.

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.

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?

I recently purchased a Toyota Grand Highlander just two days ago, and I’m experiencing a serious issue that is affecting my ability to drive the vehicle safely. At speeds between 25–40 mph, there is a significant cabin boom and echo inside the vehicle. This creates a pressure sensation in my ears, causing nausea, disorientation, and physical discomfort. I’ve only driven about 50 miles, and the symptoms are severe enough that I cannot continue driving the vehicle.
