NHTSA summary
On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until the vehicle comes to a complete stop. At this point, ABS, brake assist, stability control, and traction control functions are lost. The loss of these functions causes the vehicle to set one of three Diagnostic Trouble Codes (DTCs) based on failed performance criteria for the Electronic Brake Control Module (EBCM). These DTCs, in turn, activate several driver alerts: an audible chime, a visual “Service Brake System” message in the display, and multiple illuminated Malfunction Indicator Lights (MILs) for the ABS, Traction Control, and Brakes informing the driver of loss of functionality. The vehicle speed will also be limited to 70 KPH (43 MPH). Since opening PE24011, ODI has continued to receive reports of loss of brake assist. Some of these reports describe symptoms inconsistent with GM’s description of a spindle failure. These reports allege an immediate loss of brake assist fun

What owners wrote

“Recall was performed on truck about a year ago for the pedestrian collision automatic braking. Today the truck locked up the brakes in traffic and there wasn’t a pedestrian in sight. I believe the recall didnt truly fix the issue, as it has given false alerts before without applying the brakes”

“Radiator inlet hose leaked which caused low coolant. Check light alerted. Replace the hose. Parts are on backorder. Also had a recall on the emergency brake assist. I took this in for the recall however the alert assist still goes off.”

“When driving through an intersection, the vehicle incorrectly applied the automatic emergency braking system. There was no risk of crash, however the application of the hard braking in the intersection put me at risk of a rear collision. I do see that the new recall is supposed to address this issue.”

Filed Apr 12, 2024

“Twice in the first 6000 miles this vehicle has suddenly activated the forward collision avoidance system with emergency breaking although no cars were around. Fortunately a vehicle wasn’t behind me otherwise there may have been a collision. I took the vehicle in for service with this complaint and the dealership simply said they could not reproduce the issue during a test drive. Obviously this wasn’t helpful.”

Should you keep driving it?

This page can't tell you that. 1 of 26 reports involved a crash and 4 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
