Toyota Avalon sunroof shattered problems

Filed Jun 13, 2026 · TX

I am submitting this complaint to report a safety-related incident involving the moonroof glass on my 2013 Toyota Avalon. Vehicle Information: - Make: Toyota Avalon, 2013 - VIN: [XXX] - Mileage at time of incident: Approximately 120,000 miles While driving under normal road conditions, the moonroof glass on my 2013 Toyota Avalon suddenly shattered without warning and collapsed downward into the passenger compartment. There was no known impact from road debris, rocks, or any other external object. The incident startled me and created a potential safety hazard due to the sudden failure of the glass while the vehicle was in motion. Immediately after the incident, I documented the damage by taking photographs of the shattered moonroof. The photographs do not show an obvious impact point, bullseye fracture, or other visible indication typically associated with a rock strike. I contacted Toyota's Brand Engagement Center and opened Case Number XXX. At Toyota's request, I presented the vehicle to an authorized Toyota dealership, Group 1 Toyota Southwest Houston, for inspection. The dealership repair order documented my concern as follows: "SUNROOF SHATTERED ON ITS OWN CHECK AND ADVISE." The dealership did not identify a specific impact point, road debris strike, customer-caused damage, or provide a technical explanation for the failure. Toyota subsequently declined goodwill assistance based on the age and mileage of the vehicle but did not provide an explanation regarding the cause of the moonroof failure. I understand that my vehicle is outside of its warranty period. However, my purpose in filing this complaint is to report what I believe to be a potential safety issue involving the sudden failure of a vehicle component while driving. I respectfully request that the federal safety agency document this incident and review it along with any similar complaints involving the sudden failure of vehicle component.

While driving on a highway, the glass sunroof suddenly exploded. Fortunately the shade was closed, because the glass broke into large shards. The repair was done by a local toyota dealer and was paid in full by my insurance. My reason for this report is to call a manufacturing default to your attention.

Driving from pa to nc.on rt13 in seaford, de, driving speed limit heard loud bang. Sunroof exploded & cracked from inside.drove to 1st auto garage, they said we were 2nd toyota this week with cracked sunroof. They gave us a roll of duct tape, to get us through the monsoon. Toyota corp recommended going to dealer for evaluation as to how this happened. Have to wait 2 days for appointment. My old avalon has made many long trips without any problem. This new car has definitely not been made well. I am very disappointed.
