2025 Cadillac Optiq problems

POWER TRAIN

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found that the body control module, image processing module, short-range radar, and forward-range radar all contained outdated calibrations.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April 2026) and the visit after that (RO# [XXX], May–June 2026), the vehicle's modules were again found to contain outdated calibrations requiring full vehicle-wide reprogramming.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].

TIRES:TREAD/BELT

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.

WHEELS

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.

SERVICE BRAKES

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.

UNKNOWN OR OTHER

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.

The dealership inspected the vehicle and confirmed that the telematics module had failed. We left the vehicle at the dealership,. There were no warning lights, error messages, or other indications before the failure occurred. After the failure, several critical safety and driver-assistance systems became inoperable or severely impaired.

My GPS, OnStar and all other cruise control features have stopped functioning. The telematics module has failed within the onstar system. It is preventative by me from getting from place to place safely due to the gps not tracking correctly. The part has been on back order for over a month for me already. And I have no timeline to get a new one.

ELECTRICAL SYSTEM

Hi, For example, Audio would cut completely throughout the vehicle not allowing me to access any sources such as the On star board system in the event of a crash, music sources etc. In addition, when this happens all my safety features turn off on the car along with the screen going blank etc. This continued to happen on multiple occasions including with my kids and family in car on a 1 hour trip to Miami. I immediately one morning after experiencing the issue multiple times on my way to work texted my sales advisor. I made an appointment and dropped it off the same day. The service advisor, sat in the car with me and confirmed the issue at hand without me saying anything. After, I was told it would take about two weeks to fix my car because of the lack of EV specialist available. I contacted EV concierge the following day and all of a sudden I got a call back from the dealer saying they ran updates and that my issue was resolved. Here I am a couple weeks later having the same issue. This time now it happens on EVERY drive. To the point I had to call On star on my way home just to have someone on the line with me incase something happened. The safety features turn off. Audio cuts off and on and at this rate I can't trust the car safety wise for my kids/family and individual safety any longer. It's unacceptable that we can't trust this vehicle to keep us safe and sound. Buyback is being requested. Thank Y

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.

STRUCTURE:BODY

The Optiq daytime display brightness cannot be adjusted. It is set to automatically adjust brightness to the light conditions but in some situations it is too dim and this is distracting. The adjustment knob only works during nighttime and according to GM this is by design. The automatic daytime setting has one level of brightness regardless of the driver visual comfort.
