2024 Cadillac Lyriq problems

“My Cadillac Lyriq slams the brakes on when driving forward or in reverse with nothing in its path. This makes me very nervous to drive the vehicle as it is unpredictable as to when it happens. It scares me and affects my confidence in driving the vehicle. The entire vehicle also without warning goes completely dark meaning the screen and the entire vehicle just shut off.”

“While driving, my brakes suddenly grabbed so hard that it felt as though we were hit from behind or hit a large pot hole. There was no hole, we were not hit from behind and the brakes released immediately. We were fortunate that there was no vehicle behind us as it could have caused a collision. We were not going more than 20 mph. This has happened three times in the last 4 months. Our dealership claims there is no recall or knowledge of this happening to others.”

“I was parking in the garage and only tapped on the gas to move a little bit forward and the car accelerated on its own into a racking system and that racking system went through the wall of our home. I was only trying to move further up and barley touched the gas and then the car accelerated into the storage racking system”

“The infotainment screen in my car plus the menu control went completely dead. With the screen dead completely this mean you cannot see the speedomoter, rear camera feeds, warning symbols on the dash. You cannot see current speed, you cannot hear any sound so all alerting systems are down. You are completely blind in a vehicle built around this screen. Dealership has already confirmed faulty computer module. However was told it would have been originally resolved under N252500680. It has only been inspected by the manufacture. No warnings, no nothing, just dead screen out of nowhere that requires new part to bring online. Meaning dead dead; part is currently on back order and design changes were made after this exact model year showing knowledge of the fault.”

“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.”

“COMPONENT: Vehicle Speed Control — Automatic Emergency Braking / Anti-Lock Braking System (ABS) COMPLAINT: I am filing this complaint to report a POST-REMEDY FAILURE of the repair performed under NHTSA Safety Recall 24V589 (GM Program #N242453471) on my 2024 Cadillac Lyriq AWD. RECALL REMEDY COMPLETED: My vehicle received the Electronic Brake Control Module (EBCM) software update on August 13, 2024, under GM Program #N242453471. The recall was marked "Complete" by the servicing dealership on that date. FAILURE INCIDENT: On March 15, 2026, at low speed (under 25 mph) on a dry surface, my Lyriq failed to activate its Automatic Emergency Braking system while approaching a stationary object. The vehicle did not decelerate or stop as designed. The ABS system appeared to release braking pressure rather than maintain it, allowing the vehicle to continue forward and strike the object. The front grille assembly sustained significant physical damage as a direct result. This failure is identical in nature to the defect described in Recall 24V589 — specifically, the ABS falsely activating and releasing braking pressure during low-speed operation on a dry surface — despite…”
