2024 Cadillac Lyriq owner complaints

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

The instrument cluster display is too dim to see, making it unsafe to drive

Lyriq display not bright enough prematurely dim the display and dusk/dawn - making it very hard to see at those times - even with max dimmer setting

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.

Rear right light not working, then works, then it randomly stops working, complained to Cadillac but they keep saying nothing is wrong. I feel unsafe so to my light constantly going off especially dangerous driving at night or changing lanes on the road.

At multiple times when raining, the Automatic emergency braking system activated for no apparent reason as no hazard could be determined.

While we're driving the vehicle the adaptive cruse control was on. As we approached a vehicle ours started to slow down from 55mph to where it almost braked all the way about 2mph. The vehicle in front of us braked completely and was stopped. As soon as they were stopped, Our vehicle tried to rapidly accelerate into the back of it where we had to intervene and slam on the brakes. If we didn't do this there would have been an accident due to our adaptive cruise control failing. This has happend twice to us. Taken the vehicle to the dealership and they cant replicate the problem so there is nothing to fix. This is something that needs to be Investigated before an accident occurs.

The contact owns a 2024 Cadillac Lyriq. The contact stated while driving approximately 35 MPH, the Forward Collision Avoidance: Automatic Emergency Braking system unintentionally engaged. No warning light was illuminated. The vehicle was taken to a dealer to be diagnosed; however, the dealer stated that the cause of the failure could not be determined. The dealer was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 3,400.

On or about 11/14/24 Car found completely dead and won't start in garage. Car had about 50% charge in main battery pack and 12V completely dead. Called OnStar service and they had vehicle taken to dealership on flatbed. GM app reports Vehicle Issues: "Electric Drive Unit, Lithium Ion Battery, Electric Drive Unit, and 12V battery require your attention now." Vehicle purchased on or about 8/18/24 and at time of failure car had about 385 miles. Car kept garaged when not in use in pristine condition. Dealer reports as of 11/23/24 they do not know the problem with the car. I have been without use of my only car since 11/14/24.

This is an issue that has been under recall since june 2025. We have had the dealer do the recall, had over the air updates and it still causes all the advanced driver assistance system screen to go black and disables them. Dealer msyates all recalls have been completed.

While driving through Wisconsin on [XXX] with Super Cruise activated in 70MPH traffic the car provided me with driver's side collision warning failure notice and then a forward collision warning failure notice, but the car continued to be operating normally. A short time later a brakes overheating warning came on while the car still seemed to be operating normally and maintaining speed. I immediately disengaged the cruise control to check out the situation and the car instantly locked on the brakes, and we could see smoke and smell the burning brakes. I pulled to car to the side of the road, and we exited the car concerned there might be a fire coming from one of the 4 smoking wheels. The rotors were red hot. We remained a safe distance from the car until the brakes stopped smoking. Af

Vehicle dash won't activate beyond the welcome screen thereby preventing me from seeing the speedometer, fuel gage, lane sensors, navigation, etc. I had to drive it on side streets to the closest dealer without aid of any standard dash meters.

The vehicle's instrument panel automatically dims excessively at dusk and dawn. When it does this, the speedometer and other information in the dashboard are not visible. There is no way to adjust the brightness any higher and no way to disable this auto dim feature. This is, to my knowledge, a known software bug that has persisted for close to two years without any effort by GM to rectify this safety issue.

When approaching sunset, or when travelling under bridges, the dash dims excessively and is barely readable. I have to take my eyes off the road for extended periods of time to be able to see the information. The excessive dim does not reset itself, when the ambient lighting returns to normal, for a prolonged period of time. Complaints to the dealer service department, GM EV Concierge, and OnStar have not had any effect on resolving this. Tnis is an ongoing problem since delivery of the vehicle.

I am submitting this follow-up to document new information and continuing concerns regarding my 2024 Cadillac Lyriq EV, which experienced sudden unintended acceleration during a parking maneuver. GM and its claims administrator (ESIS) have now completed their review and issued a denial letter on October 31 2025, stating “no defects were found.” However, the denial included no supporting technical findings, analysis, or data explaining how that conclusion was reached. Despite multiple written requests, GM has not provided the following key event-data modules: – Brake System Control Module (EBCM/iBooster) export (brake pressure, pedal position, brake override flags) – Propulsion/Drive Control Module data (torque request vs actual torque and accelerator input) – Front Camera Module metadata

While driving northbound on [XXX], south of Oklahoma City, at normal highway speed, at night, in the rain (on [XXX]), this EV lost all power to the wheels and the regenerative braking ceased to function. It appears that all flow of electrons from the batteries to the drive motors, and from the regenerative brakes to the batteries stopped. I still had dashboard lights, steering, and conventional brakes. I was able to safely coast to a stop on the highway shoulder. I set the parking brakes, put the “transmission” into “park”, and turned off the power button. I then restarted the car, and all was normal again. I continued my drive from Austin, TX, to Evergreen, CO with no additional incidents, arriving on [XXX]. This is reminiscent of the “blue screen of death” in old Microsoft desktop

I am writing to report an issue with the windshield durability on my 2024 Cadillac LYRIQ. Over the past three weeks, I’ve experienced three separate instances where small rocks struck the windshield while I was driving, each impact resulting in a crack or chip. In my experience with previous vehicles, similar impacts would rarely, if ever, result in such immediate damage, which raises concerns about the material or design of this particular windshield. This frequent damage has quickly become costly and frustrating. Windshields should withstand small impacts to a reasonable extent, and this does not seem to be the case here. I am also reaching out to Cadillac to address my concerns, but I wanted to report this issue to NHTSA in case other drivers are experiencing similar problems. Please
