General Motors, LLC (GM) is recalling certain 2023 – 2024 model year Cadillac Lyriq vehicles. The driver video display may go blank while driving.

Risk: A blank video display can result in a loss of critical safety information, such as the speedometer, warning lights, and rearview camera image, increasing the risk of a crash.

SUSPENSION:FRONT:STABILIZER BAR

General Motors LLC (GM) is recalling certain 2023-2025 Cadillac LYRIQ vehicles. The left or right front stabilizer bar bracket bolts may have been improperly tightened, which can allow the bolts to loosen and separate from the vehicle frame. A detached stabilizer bar or bracket can damage the vehicle's high voltage cables or EV battery coolant lines.

Risk: Damaged cables or coolant lines can result in a vehicle shutdown, causing a loss of drive power and increasing the risk of a crash.

EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL

General Motors, LLC (GM) is recalling certain 2025 Cadillac LYRIQ vehicles. The owner's manual inaccurately describes the rear outboard head restraints. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 202, "Head Restraints."

Risk: Incorrect head restraint information may lead to improperly adjusted head restraints, increasing the risk of injury in a crash.

ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY

General Motors (GM) is recalling certain 2026 Cadillac VISTIQ vehicles and 2025 Cadillac LYRIQ vehicles. The bolts attaching the high voltage battery to the interior floor may be missing or loose.

ELECTRICAL SYSTEM:WIRING

General Motors, LLC (GM) is recalling certain 2024 Cadillac Lyriq, Chevrolet Blazer EV, Chevrolet Silverado EV, GMC Hummer EV SUV, and GMC Sierra EV vehicles. The electric motors in the rear drive units may have insufficiently insulated wires that can contact each other, resulting in a loss of drive power.

Risk: A loss of drive power increases the risk of a crash.

ELECTRICAL SYSTEM:BODY CONTROL MODULE:SOFTWARE

General Motors, LLC (GM) is recalling certain 2023 Cadillac LYRIQ vehicles. The body control module (BCM) may have been updated with incorrectly calibrated software and fail to make the pedestrian warning sounds.

Risk: Without external warning sounds, pedestrians may be unaware of an approaching vehicle, increasing the risk of a crash.

SEAT BELTS:REAR/OTHER:ANCHORAGE

General Motors, LLC (GM) is recalling certain 2023-2024 LYRIQ vehicles. The bracket that anchors the left-rear and center-rear seat belts may have been improperly welded to the seat frame.

Risk: An improperly welded seat belt bracket may not restrain an occupant as intended, increasing their risk of injury during a crash.

ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY

General Motors, LLC (GM) is recalling certain 2022 GMC Hummer EV and 2023 Cadillac Lyriq vehicles. Certain connections within the high-voltage battery pack may be out of position or incorrectly welded, which can cause a loss of drive power.

SERVICE BRAKES

I was driving on Saturday September 3 at 5 pm over the Chain Bridge entering Washington DC. Traffic was heavy and the auto brake went on when I was about 15 feet from the car in front of me. I was using one-pedal driving and when I pushed on the gas slowly we started slowly moving forward. I was traveling around 3 or 4 miles an hour and the car would not slow down when I took my foot over the pedal. One pedal driving apparently stopped working. I then applied the brakes gently and the brakes did not work. I then pushed the brakes hard and still no brakes worked. I tried pumping the brakes and nothing worked. The car gently ran into the car in front of me causing no damage to the car in front and he kept on his way. My front grill was cracked and bumper was slightly damaged. The signal on the dashboard said parking brake engaged which it was not. While the auto safety brake engaged minutes earlier when it was not needed it did not work when the car was drifting uncontrollably into the car in front of me.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING

Backing out of driveway and screen went black and a collision occurred a second or two later. We have had the Lyriq in the shop multiple times for glitchy screens and screen going black but never has been fully resolved. I did recieve a recall letter (unfortunately I threw it away) but now it shows no recalls (strange). This black screen issue has been a problem since day 1 but now it has resulted in a collision. I have been unable to even back my car out of the garage when raining due to the sensitivity of the collision detect so there is NO excuse that it didn't alert. Cadillac has had the car since the accident and claim nothing is wrong with it and they are not responsible. I do not believe that. I have met with dealership GM who is looking into this further. I wanted to bring to the NTSB as this is 100% a safety concern. Thank God there wasn't a child on a bike or a baby in a stroller behind us. This didn't result in any human harm but the vehicle sustained damage that I believe was the direct result of malfunctioning technology on the car to prevent it.

SERVICE BRAKES

While driving in one-pedal driving mode at the high setting, an error message appeared and one-pedal driving suddenly shut off and switched to a more standard drive mode where engine braking is disengaged. This happened while drive was engaged and stopped at a red light. The car briefly lurched forward and the car engaged an emergency brake to prevent the car from rolling into the vehicle in front of me. This incident was unpredictable and resulted in an unexpected change to the drive mode I had selected which could have lead to a collision.
