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.

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

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.

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 havin

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.

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.
