Owners have filed 50 complaints
about the 2024 Cadillac Redundant Lyriq with NHTSA between 2023 and 2025.
The largest single group is the driver assist & collision avoidance.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

A spike years after the car went on sale usually means a part wearing

NHTSA investigations into the 2024 Cadillac Redundant Lyriq
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Electronic Brake Module Component Failure
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 th...

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 (timestamps and event record IDs) Additionally, several data discrepancies remain unresolved — including mismatched timestamps between the ASCM and FCM reports and camera images that do not correspond to the actual crash scene. On October 29 2025, GM publicly announced Customer Satisfaction Program N252521980, covering certain 2023–24 Cadillac Lyriq and 2024 Chevy Blazer EV vehicles for a Brake System Control Module software update due to possible brake-control performance issues. Because my incident involved loss of braking response, this recall appears directly relevant. I have requested confirmation whether my vehicle is affected and whether this module was analyzed in GM’s investigation, but have not received a reply. I am requesting that NHTSA review GM’s handling of this case to determine whether the engineering review was complete and whether the vehicle’s BSCM or related systems could be implicated in unintended acceleration or brake override failures. GM Case #1092995 – Submitted to ESIS/GM Product Investigations Group. Thank you for your attention and for documenting this matter in the defect database.

The contact owns a 2024 Cadillac Lyriq. The contact stated while driving at approximately 3 MPH as she was entering her garage to park the vehicle, she depressed the brake pedal, however, the vehicle continued forward and crashed into a tool chest located at the back of the garage wall. The contact stated that the front of the grill and the front bumper were damaged and had to be replaced. The contact stated no warning light was illuminated. The contact stated that failure reoccurred when she was parking the vehicle in a parking lot. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the ABS system had failed and caused a loss of braking ability. The contact was advised by the dealer that the failure was related to NHTSA Campaign Number: 24V589000 (Service Brakes, Hydraulic). The contact had the recall completed at that time. The manufacturer was informed of the failure. The failure mileage was 3,000.

EXTERIOR LIGHTING
The auto leveling lights drift during driving. On staff up, the headlights will point up and down, then self level. However, for the past week, the right headlight drifts down towards the road and the left headlight will drift upwards after about 20-30 minutes of driving. The downward drifting headlight only illuminates about 1 car length ahead while the upward drifting headlight will point towards overhead street signs. This causes reduced visibility with increased flare and reduced headlight throw at the same time. It also is dangerous to incoming traffic since the left headlight ends up drifting upward to produce a throw similar to a high beam, even though the high beams are off. The only way to get the lights to re-level is to shut off the vehicle and restart. Even after this, the lights will only be at the correct level for about 20-30 minutes as they start to drift in opposite vertical directions while driving. There have been multiple reports of similar cases on forums discussing the Cadillac Lyriq. Since the problem only occurs noticeably after 20-30 of night driving, the dealer has stated they can not reproduce it while in their possession. There are no warning messages or codes displayed.

While driving the 12V battery system failed as well as the high voltage charging system. The vehicle lost traction control in the rain and was slipping on the road. The forward collision detection also intermittently goes out. If you are in one pedal driving mode and using adaptive cruise control when the forward collision detection goes out it will deactivate adaptive cruise control and apply enough regenerative breaking to rapidly slow the car. If the driver does not have their foot on the accelerator when this happens and you are in traffic it could cause an accident. The vehicle is not saving any diagnostic information regarding these failures and dealerships will not work the failures without diagnostic codes.
