EXTERIOR LIGHTING
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.

EXTERIOR LIGHTING
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

Vancouver, WA
EXTERIOR LIGHTING
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.

EXTERIOR LIGHTING
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.

Simpsonville, SC
EXTERIOR LIGHTING
We encountered consistent loss of or erratic headlight operation. The behavior was that lighting would simply fail on one or both sides of the car, often along two-lane roads with curves in the road where it is critical to judge distance to oncoming traffic. Other times the lights would dim and wash out the ability to clearly see the road ahead. The dealer has replaced the headlights three times already. An associated lighting module was also replaced more than once. Note that this issue is still present so we are unable to use the vehicle now after dark.

There is a problem with the dashboard lighting. It is very dim and hard to read the dash to choose and view options and screen in general. I noticed this the day I picked up the new car. The dealer said there was nothing he could do. I contacted Cadillac and was told to go back to dealer and have him make a TAC call with GM for adjustment. They did this and said it met there specs. This is a very dangerous safety issue as when you are driving you spend to much time trying to see dashboard for adjustments and you can’t keep your eye on the road. I filed a complaint with Cadillac Customer Assistance, case # [XXX] and nothing is getting done about the problem. I’ve talked with several Lyric owners with the same problem and I see online a lot of customers complaining. I’m hoping you can get involved and get Cadillac to resolve this problem for myself and many other owners. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
