Operating the vehicle as instructed and used the Super Cruise feature (GM's hands-free cruise control driving assist) as it should be, by paying complete attention while not having to keep my hands on the steering wheel. As Super Cruise was activated, as it was for the majority of the roadtrip from [XXX] to [XXX], and once in the [XXX] area of [XXX], as the vehicle was driving straight ahead into a construction zone, the Super Cruise/Vehicle detected it was going through a construction zone and the Super Cruise remained activated and working and then in a literal blink of an eye, it automatically disengaged without any "Take Control" notice or warning and immediately hit into a construction…

On or around [XXX], while driving at approximately 40 mph, the automatic emergency braking / auto collision assist system on my 2025 Cadillac OPTIQ (VIN: [XXX]) activated without warning and brought the vehicle to a sudden stop. There was no obstacle, pedestrian, or hazard present in the roadway ahead of the vehicle at the time of activation. The vehicle was brought to Moore Cadillac, Chantilly, Virginia (RO# [XXX], check-in January 9, 2026). The dealership technician was unable to duplicate the concern on a diagnostic road test but found that the body control module, image processing module, short-range radar, and forward-range radar all contained outdated calibrations. Vehicle-wide module…

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 didnât 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 âunusualâ. There was no warning lamps, messages, etc. I was lucky that I wasnât on a highway traveling ay high speeds. There was only about 2,500 miles on the tire.

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.

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 âABS Activeâ 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…

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…
