What 87 owners told NHTSA about the 2024 Hyundai Tucson Fuel Cell

On Wednesday, May 13, 2026, I turned off the highway and came to a stoplight. While preparing to accelerate as the stoplight turned green, I heard what sounded like a gunshot and saw that my entire rear window had spontaneously shattered. There was no external impact which caused this to occur. I have photos of the incident. Although my one year old son was not in his rear facing car seat at the time, if he had been, he would have been at risk of injury due to glass fragments. I was at risk as the sound startled me into breaking when I should have been accelerating with the rest of traffic and it left my interior exposed to the elements. I am scheduled with Safelite repairs through my insurance company to repair the window on Monday, May 18th. There were absolutely no messages or any symptoms prior to the spontaneous shattering of my window. After researching, according to Chimicles Schwartz Kriner & Donaldson-Smith LLP, there is currently an investigation for a potential class action lawsuit regarding an alleged defect of my make and model causing spontaneous rear window shattering.

My car was parked, without any trees or other objects that could possibly damage my car near by, and the glass on my front windshield cracked for absolutely no reason. It starts where the glass attached to the car and spreads to the middle of my windshield. I believe there is an installation defect because this car is only 2 years old and has never had any damage to it. I also read that this is a common problem with other Hyundai models.

The panoramic sunroof in my 2024 Hyundai Tucson Limited shattered while driving on the interstate. It sounded like an explosion and frightened me while driving. I was able to maintain control of my vehicle, and fortunately, my headliner was closed, preventing glass from falling on me. The flying debris created a hazard for other drivers. I took my vehicle to the Hyundai dealership where I purchased it, and I am awaiting a response from the Service Manager for repair. The vehicle is less than a year old and has less than 9,000 miles on it.

While driving my 2024 Hyundai Tucson at highway speeds on a clear day with no surrounding traffic, I was startled by an extremely loud bang that sounded like an explosion. Pieces of shattered glass rained down inside the passenger cabin, creating a potentially hazardous situation. This incident was a traumatic experience. The sudden and unexpected event had the potential to cause serious injury to the driver, as well as increase the risk of a collision due to the shock and distraction it caused. Additionally, other pieces of shattered glass were propelled from the vehicle, posing a risk of injury or damage to other drivers on the road. Upon physical inspection, it was noted that the glass from the panoramic sunroof was bowed upwards, which suggests the explosion originated from within the sunroof and NOT an external factor such as road debris or a rock. The vehicle, which is less than a year old, is currently at the Hyundai dealership pending an investigation. Given the severity of the incident and the potential risks to driver and passenger safety, I strongly recommend that a recall be issued or a comprehensive investigation be initiated by the NHTSA to prevent further occurrences of such dangerous incidents. Safety must be a priority, and swift action is necessary to ensure that no other drivers or passengers are at risk of similar events.
