while traveling at highway speed on the interstate in Alabama, the panoramic roof glass on my 2025 Ram 1500 spontaneously shattered and expelled outward from the vehicle. There was no prior impact, road debris strike, or warning of any kind. No injuries occurred, but the sudden loud explosion of glass was an extreme distraction and created a serious safety hazard for myself, child in the back seat and other motorists on the interstate. The failure is consistent with a known manufacturing defect in tempered glass — spontaneous shattering caused by internal stress or contaminants such as nickel sulfide inclusions — and is not consistent with road hazard damage. Glass that fails due to external impact typically breaks inward; this glass blew outward under pressure. I took the vehicle to my Ram dealership, who denied my warranty claim by citing a 1-year/12,000-mile limitation for glass. However, the FCA US LLC Basic Limited Warranty documentation lists specific components subject to that limitation — windshield and rear window among them — and does not include panoramic roof glass. The dealer’s denial appears inconsistent with the plain language of the warranty. I am requesting that NHTSA: 1.Open or add this complaint to any existing investigation into panoramic roof glass failures on Ram 1500 or other FCA/Stellantis vehicles; 2.Investigate whether a defect exists that warrants a safety recall; and 3.Record this complaint for use in any future enforcement or recall determination. This incident posed a serious safety risk at highway speeds and I believe other Ram 1500 owners may be at risk of the same failure.

While driving on the highway, I first noticed the vehicle becoming difficult to steer. The steering felt unusually heavy and sluggish, as if power steering assistance was reduced or failing. Shortly after this began, multiple warning lights illuminated across the dashboard. At that point, braking performance also became severely compromised. The brake pedal felt soft and traveled nearly to the floor with very limited stopping power. The vehicle required significantly increased distance to slow and stop, creating a serious safety hazard in active highway traffic. The combination of reduced steering assist and severely degraded braking performance made the vehicle difficult to control and presented a significant safety risk. I was able to bring the vehicle to a stop and it was later towed to a dealership. At the time of inspection, the battery was found to be dead. I had recently returned from a 5-day trip and the vehicle required a jump start before this driving event. The dealership replaced the battery and stated the vehicle was operating normally after repair. However, the incident involved progressive loss of steering assist followed by significant loss of braking performance at highway speed. I am reporting this as a serious safety concern because multiple critical vehicle control systems were affected while driving. I am concerned about potential recurrence of this issue and the risk it presents to driver and public safety. The vehicle is available for inspection.
