2024 Cadillac Lyriq lights problems

Filed Jan 29, 2026 · Electrical, Lights · CA · fire

My 2024 Cadillac EV is only 9900 miles. I was driving the car on Sunday Jan 11, 2026 with my family when we noticed smoke filled inside the cabin. My 3 children (a [XXX] , a [XXX] old, and a new-born who is [XXX] old) were in the car; they inhaled the smoke. We evacuated the car and called onstar for assistance - who towed the car. The smoke originated from the tailgate of the car. Alarmingly, just 3 days before this incident (Jan 8, 2026), I took the car to the local Cadillac dealership to complain about water intrusion in the left taillight that is in the liftgate. The service advisor created a repair order and sent me back saying it would take 10 days to arrive. Upon my specific inquiry, the advisor stated the car was safe to drive and assured me that I would not get a ticket. Since the event (5 days later) it was confirmed by the service advisor that the same water intrusion event lead to the electrical fire that burned a connector, a module, and multiple wiring components causing the fire.

The back up lights when in reverse at night are inadequate to safely back the vehicle up. This is true whether one is using the rear window and rearview mirrors or one is using the back up camera. No more than 10 feet of area behind the vehicle can be seen by using these lights.

Inside display dims inappropriately, even in daylight making it impossible to see navigation. Hazard when trying to drive on road. Could cause accident. Needs option to manually brighten/dim. Auto dim feature in this vehicle is terrible.

The bigger issue is the car will prematurely dim the display and dusk/dawn - making it very hard to see at those times - even with max dimmer setting. Took it to the dealer multiple times they say it’s working as expected but it’s a known issue for all lyriq owners that GM ignores

Unable to get display lighting bright enough to adequately read instrumentation when coming out of garage into low atmospheric lighting. Have instrument display lighting rheostat turned up to maximum but sensors don't allow the display to brighten. The vehicle lighting sensor is not blocked. The rheostat should be able to turn the display to full bright, but isn't designed that way. Definitely a safety issue. Cadillac dealership says there is nothing they can do about this situation, but acknowledge it's a widely reported complaint. The manual rheostat should be able to turn the display to full bright by selecting the maximum setting. Unfortunately it's not designed that way.

During dusk/dawn exterior lighting conditions, the informant screen is too dim to use. i.e. can't change drive mode to snow/ice, or locate any other controls.

Right rear taillight and brake light fail to light intermittently. This is a known defect on many other Lyriqs. When this failure occurs, the vehicle is not compliant with state laws regarding having working taillights and brake lights, and could result in a moving violation ticket. Cadillac should be required to recall and repair/replace these lights.
