NHTSA complaint #11763943

Owner complaint summary

I am reporting a serious safety concern involving the sunroof glass on my 2021 Toyota RAV4 Hybrid Limited AWD. On July 3, 2026, at approximately 37,350 miles, I was driving the vehicle when the entire sunroof glass suddenly and catastrophically shattered. There was no traffic around me, there was no debris in the roadway, I was not traveling under an overpass, and I am not aware of any impact or other event that could have caused the glass to break. The failure was completely unexpected. I heard a very, very loud sound, similar to a gunshot. Immediately afterward, the entire sunroof glass had shattered into small granules. A very small piece of shattered glass also flew off the vehicle. I was able to quickly close the interior sunroof visor, which fortunately prevented the majority of the shattered glass from falling into the passenger compartment and prevented injury. There was nevertheless some glass that fell into the roof liner. I immediately contacted my insurance company and the car was towed to my Toyota dealership. The sunroof was replaced with a Toyota original part and the replacement was paid by my insurance company. This incident created a significant safety hazard because the sunroof glass failed suddenly and violently while the vehicle was being driven. The extremely loud explosion-like sound and the sudden loss of the sunroof glass could cause a driver to lose control of the vehicle or could result in glass striking occupants. In this instance, I was fortunate that the visor was closed quickly and that there was no surrounding traffic. I believe NHTSA should investigate whether there is a defect or other safety-related problem with the sunroof glass or its installation in this vehicle, particularly if similar spontaneous breakage incidents have occurred in other Toyota RAV4 vehicles. I am reporting this incident because the glass appeared to fail spontaneously, without an apparent collision, road debris, overpass, or other external impact.
