Vehicle Information Make: Cadillac Model: CT5 Model Year: 2025 VIN: [XXX] Odometer: 30905 Incident Information: Date of Incident: [XXX] Vehicle Speed: Approximately 54 mph Component Involved: Front Sunroof Glass Assembly Description of Safety Defect On [XXX], at approximately [XXX] hours, I was driving my 2025 Cadillac CT5 at approximately 54 mph when the front sunroof glass suddenly exploded without warning. The event was accompanied by an extremely loud explosive noise, which initially made it difficult to identify the source of the incident while operating the vehicle. Upon inspection, I discovered that the front sunroof glass had shattered. The glass appeared to have fractured and displaced outward, which is inconsistent with damage typically caused by road debris striking the exterior surface. I reviewed my vehicle's video recording from the time of the incident and found no evidence of any object impacting the sunroof immediately before the glass shattered. The sudden failure of the sunroof created a significant distraction while driving and presented a potential safety hazard to vehicle occupants and nearby motorists. The unexpected explosive sound could have caused a loss of vehicle control or led to a traffic accident. Dealer Response: Immediately after the incident, I brought the vehicle to an authorized Cadillac dealership for evaluation and warranty consideration. The dealership declined to process the repair as a vehicle defect or warranty claim and advised that the damage should instead be addressed through my automobile insurance carrier, Progressive Insurance. No evidence of an external impact was identified during my initial review of the incident, and the dealership did not accept the failure as a manufacturing or component defect. Insurance Claim: Following the dealership visit, a claim was immediately submitted to Progressive Insurance regarding the incident Claim number [XXX].

The car was parked for 4 to 5 hours. The keys were with me and the car was unoccupied. It proceeded to unlock from being parked, the alarm went off, and the vehicle rolled down a hill, hit a person and another parked vehicle. The incident occurred on August 8th, 2026. Case No. 26054085 Clayton County Police Department 770-477-3747. The car is being repaired and has been inspected by Cadillac. They were unable to determine the cause. We have video of the incident. With the car being unoccupied we have no idea what the dashboard said or any warnings. While the car was moving it pinched a man in between the car and another car. EMS was called and he was taken to hospital for observation.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I put up a rubber stop to test the emergency stop feature the car is equipped with. With car moving either forward in drive or backwards in reverse the car would not automatically stop before hitting this two foot high aid. A warning vibration is felt just before the car struck the device but the way I understand it in the owners manual the car should come to a complete emergency stop. This could endanger anyone or anything that the driver did not see while moving the car, i.e., a child on a tricycle for example.

VISIBILITY/WIPER
I went to test drive this car on Saturday 9/27, and noticed that the rear view mirror--the actual mirror, not the video screen inside it--was vibrating/shaking immensely as I drove it. I told them I'd buy the car, but they have to fix the mirror. Tuesday 9/30 I bought the car, with the assurance that the mirror had been fixed. Apparently there's a screw that was loose. Upon leaving the dealership, I discovered that the shaking/vibrating hadn't gone away--it was merely diminished. I took the car back. We discovered another identical model and year of the car on the lot, and it exhibited the exact same problems. Initially the same screw was loose, but after fixing it that mirror also gave the same shaking/vibrating. We determined that this looks like an overall problem with this model and year, at the least, and the dealership didn't know what to do. I declined the car. This is a serious issue with rear visibility. The rear view mirror is almost unusable, and it's almost illness-inducing to see in action.

ENGINE
I just bought a new car 5 days ago, and after running 378 miles, it started to pull the cylinder. The after-sales service is still delaying the time. I don't know what to do, and Cadillac still doesn't give me a mobility scooter.

This vehicle VIN has a feature called Traffic Sign Assistant, which will provide a readout of the legal posted speed limit for the road being traveled. That information is being provided by a third party source being google maps, the internet is showing increased concerns of this such as below links demonstrate from other consumer drivers using google maps displaying incorrect speed limits on highways or back roads with no resolution. [XXX] [XXX] We also tested another vehicle in a known problem area which is near [XXX] [XXX] in Nashua NH ,the legal posted speed is 55mph and google maps displays 65 mph while waze app displays correct legal speed of 55mph. We drove with the flow of traffic, seeing other people using phones and mapping on this route. Customer states ,Back roads in town of Henniker NH with posted speeds of 25-35 mph on [XXX] or [XXX] or [XXX] near [XXX] in Concord NH display in the car of 55mph. This is an Unsafe condition as watching the flow of traffic in Nashua NH moves at 70 MPH or more since google mapping is saying 65mph with posted legal speed of 55 mph confirmed 55 speed limit is correct from troop G NHSP [XXX] Department of Safety. If google mapping cant display a correct legal speed limit on a highway or back road, they should display either (--) or nothing at all in vehicles , especially if the vehicle has any type of auto speed control being controlled from this source.
