2024 Cadillac Lyriq

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.

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.

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 computers — fixed the problem by cycling the ON / OFF switch. Unfortunately, doing this when driving at 75 mph is less than ideal, and is a real potential safety problem.

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. After it appeared safe, I reentered the car and determined the brakes (parking brakes) were fully engaged and the car would not move. We contacted OnStar for assistance and waited. After a significant time (it seemed like quite a while) I suddenly heard the sound of the parking brakes electrically releasing. Shortly after that I started and tested the car again and it would move so we slowly drove it off the busy interstate to the next exit a short distance away and continued working with OnStar to obtain a tow to a Cadillac dealership. After working with OnStar for several hours and determining that there would most likely be no tow truck coming, we decided to test drive the car around the area now that the brakes had cooled off. We ended up renting a 'safety' car that my wife would drive, and I would try to drive the car back to Minnesota to our dealer. The car operated normally for the drive home, but we did not use any cruise control just in case. It was my belief that a system communication issue told the brakes to engage and that since the Super Cruise was engage the motors just added more power to over-come the drag on the brakes until they over heated.
