2021 Toyota Highlander: sunroof shattered

Filed Sep 19, 2025 · MT

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.

The sunroof exploded in 75 degree weather. My safety was put at risk by the sunroof exploding and others were put at risk that were following on highway from flying glass. The problem was confirmed by safelite. Toyota refuses to take any responsibility. The sunroof was inspected and repaired by safelite. There was no warning that the sunroof was going to explode. The vehicle maintenance is at the highest level.

We were driving across the Texas panhandle at the posted speed limit of 75 mph. It was about noon, the outside temperature was about 60 fahrenheit & there was a cross wind of about 30 mph. There were no vehicles in front of me & the closest approaching vehicle was a good half mile away. No vehicles had recently driven past us from the approaching lane. There was a sudden explosion above us & through the 1-2" gap in the motorized retractable sunshade of our moonroof, I could see broken glass. Through that gap, some glass fragments fell in on us. I pulled over to stop, got out & inspected the roof, & the front glass panel was completely shattered & 75% gone. Many of the fragments were on the sunshade & I removed those. Going at about 40 mph we went to the closest small town where a mechanic removed some residual loose glass, vacuumed as much off the shade as he could, & patched the hole with cardboard held in place by duct tape so we could get home for a repair. If the shade had not been almost closed, we would have been showered with glass with risk of bodily & eye injury.

Driving back from lunch with a friend we heard a pop and loud shattering sound as my sunroof glass exploded for no apparent reason. I called the dealer where I purchased the car 40 days ago with every extended warranty that I could. Toyota denied the claim stating that there was not any bulletins stating material defect and that the glass was not part of any warranty and I will have to file an insurance claim.

The sunroof on my 2021 Toyota Highlander spontaneously exploded. I was merging onto a highway but just started to accelerate normally - was going approximately 20-30 mph. The entrance ramp was a merge lane, and there was a semi truck with no load, so intentionally accelerated slowly to allow the truck driver easy access to the highway. The temperature outside was approximately 80 degrees, clear skies, no construction around me. No object from the truck in front flew backwards to hit my Highlander. It sounded like a gunshot, but felt no impact to the Highlander. I slightly opened the sunroof liner, because the loud noise seem to come from directly overhead. I saw that the sunroof was shattered, so quickly closed the sunroof liner to prevent any glass from falling down. I exited the first exit and drove to the dealership. Ironically, I already had an appointment for routine maintenance. When I arrived at the dealer - I saw that an approximate 6" x 2" section of glass was missing, and the rest of the sunroof was completely shattered. There is no visible damage to any other part of the Highlander. The service advisor looked and it looked like the glass looked like it was pushed up, in his words "looked like it was pressure induced from the inside". My friend searched - and found this is a common problem in 2020-2021 Toyota Highlanders.

I came to a stop sign in my neighborhood on Windy Drive and I heard what sounded like a gunshot. I immediately put my vehicle into park and got out and noticed that the sunroof glass was shattered. The best description I can give is the glass looked like a volcano where the broken pieces were facing upward. I then proceeded to my local Toyota dealership located in Alexandria, Louisiana. They told me my car was out of warranty and provided me with a quote of $1,450.00. I believe that this occurred due to a defect from the manufacturing process and I don't think the consumer should be responsible for the cost to fix the sunroof. After researching on the internet, I see several complaints from other Toyota owners that have experienced the same incident and I feel this should be a recall on Toyota's part. I am frustrated that I have to pay $1,450.00 for damage that I know was a manufacturing defect after I researched and found hundreds of other consumers with the same experience.

The contact owned a 2021 Toyota Highlander. The contact stated while driving approximately 50 MPH with a passenger in the rear passenger seat, she heard an abnormal popping sound and the sunroof exploded from the inside-out without warning or impact. The shattered pieces of glass were propelled outside the vehicle. The occupant in the rear passenger seat sustained a cut on the finger but did not seek medical assistance. The vehicle was taken to the local dealer where it was diagnosed that the sunroof glass panel needed to be replaced and it was confirmed that the failure was not due to an impact to the sunroof. The vehicle was repaired. The manufacturer was not notified of the failure. The contact stated that she was concerned about a potential reoccurrence of the failure. As a result, she traded the vehicle. The failure mileage was approximately 7,500.

I have a 2021 Toyota Highlander XLE with a panoramic sunroof. on 5/11/2022 I was driving on the road when I heard an extremely loud explosion. I looked around and didn't see any damage, then I pulled off the road to discover that the sunroof had exploded. I called the dealership and they referred me to Safelite. Safelite took my information and called me back 2 days later to inform me that they don't stock the part I have to go to the dealer. I booked an appointment with the dealer (Sheehy), I took the vehicle in, they inspected, and I was told by Sheehy that "they've never heard of such a thing" and they were going to call the manufacturer to see if they will approve my repair under warranty. They called me back about a week later to say my claim for repair costs was denied due to, in their words "outside influences". There were no rocks, debris, etc. found that could have contributed to the moonroof shattering. Fortunately, I had the shades pulled otherwise I would have been covered in broken glass. There was no damage to the shade to indicate an object fell on it. After a quick google search, I saw that other SUV owners had experienced this same phenomenon and were told the same thing- outside influences caused this. Toyota should inform consumers about this issue and fix it no questions asked when this happens rather than try to brush it under the carpet especially when the vehicle is still under warranty. This presents a road safety issue as flying glass could get injure other people.
