I one pedal drive and concurrently regenerative breaking is on since November of 2018. Having reversed out of the garage and then closing the garage door and before I reversed on to the street the OptiQ roughly lurched forward while stationary. While slowly entering the home garage to park, the OptiQ performed a forward lurching over a wooden barrier touching the wall (5/31/25). The front grill has indentations. Cavender Cadillac advisor has not returned my call.

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.

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 reprogramming was performed as the repair. At the very next service visit (RO# [XXX], April 2026) and the visit after that (RO# [XXX], May–June 2026), the vehicle's modules were again found to contain outdated calibrations requiring full vehicle-wide reprogramming. The root cause of the recurring calibration failure has not been identified or permanently resolved by the dealer as of the most recent service visit on June 11, 2026. This vehicle has been out of service for approximately 74 cumulative days across 9 service visits since delivery on [XXX].

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.
