Car was t- boned at Intersection on right side. Front passenger sustained bruising but did not require hospitalization. Side airbag did not deploy.

Continental Cross Contact RX, 245/50 R20, M&S I was driving my 2025 Cadillac Optiq. I was about 1 mile from my home driving at 35 mph or less when the rear passenger side tire blew out. There was a fist size hole in the track (bottom of tire) . I definitely didn’t run over anything. The car was towed to a Cadillac dealer who put on a new tire at my expense. At the dealers they said it was “unusual”. There was no warning lamps, messages, etc. I was lucky that I wasn’t on a highway traveling ay high speeds. There was only about 2,500 miles on the tire.

I am filing this safety complaint regarding my 2025 Cadillac Optiq with approximately 6,500 miles. On May 25, 2026, during rainy/wet road conditions, the vehicle failed to stop normally on two separate occasions while I was approaching stop signs at low speed. I was driving cautiously and was not speeding due to the rain. During the braking events, the vehicle displayed an “ABS Active” message/indicator, but the vehicle did not decelerate or stop as expected. I had to continue attempting to brake, and the vehicle traveled farther than it should have before stopping. This happened twice in the same day under wet conditions. Fortunately, there were no other vehicles or pedestrians in the intersection at the time, so no crash or injury occurred. However, if another vehicle or person had been present, this could have resulted in a serious collision or injury. I checked the NHTSA and Cadillac/GM VIN recall lookup and did not see an active recall listed for my VIN. However, I am aware of public information regarding a GM/Cadillac service update involving the Brake System Control Module and reduced deceleration during low-speed ABS braking events. I am concerned that my vehicle may have a braking/ABS defect or brake control module software issue. I do not currently feel safe driving the vehicle until it is inspected. I am requesting that this issue be investigated because the vehicle displayed ABS activity but did not stop normally during low-speed braking in wet conditions.

Vehicle experienced a sudden tire blowout and loss of control matching recall 25V704000. Rear driver side Tire ruptured while driving, bounced car to the left , hit car mirror off of a mailbox, then car bounced off to the right of road. When I described this incident to my friend who works at GM quality, he believes this description fits perfectly the tire failure/ recall GM had on continental tires in 2025. However, my VIN shows 0 active recalls. The manufacturer's recall boundary is too narrow and must be expanded to include this vehicle block. The dealer charged me $1,100 for consequential wheel damage.

On or about December 2, 2025, I discovered that multiple connected and safety-related systems on my 2025 Cadillac Optiq had stopped functioning. We believe a GM over-the-air software update was installed the weekend prior, and the dealer has inferred that the update may have caused the failure. We brought the car into the dealership on December 16th. The car was "fixed" and I picked up later that evening. i was told that the OnStar module is broken and is on national backorder. The OnStar module is connected to, several critical safety and driver-assistance systems which are inoperable. These include, but are not limited to: OnStar emergency services driver-assist systems, GPS and navigation functions Bluetooth, Wi-Fi, and vehicle internet connectivity. Although the vehicle is technically drivable, the loss of these systems poses a significant safety risk to occupants and others on the road. The vehicle cannot contact emergency services in a collision, cannot send diagnostic data, and lacks essential driver-assistance and navigation capabilities. The dealer has confirmed the problem, but the replacement telematics module is currently backordered with no clear timeline, and they stated the delay could last weeks or longer. Because the failure appears to have been caused by a GM-issued OTA update, and because essential safety systems are offline, I am concerned about both the defect itself and the extended inability to repair it due to unavailable parts. UNKNOWN whether GM has conducted a broader inspection or analysis of this update or component, but the failure has been reproduced and confirmed by the dealer’s service department.
