2025 Cadillac Optiq owner complaints

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.

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.

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 avai

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.

We brought the car into the dealership on November 26th. The car was "fixeed" and we picked it up on December 2nd. Before we were able to leave the lot, the telematic system broke again. 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 se

Horrible glare from the dashboard on the windshield. Makes it difficult to see when driving during the day.

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.

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 “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 bee

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.
