General Motors is recalling 21,469 model yeasr 2023-2024 Cadillac LYRIQ all-wheel-drive vehicles (AWD). The anti-lock brake system (ABS) may activate unexpectedly and release brake pressure in the vehicle’s service brake system. GM provides the software involved with this recall. Rear-wheel drive vehicles are not affected.
According to documents made public this morning in the required safety recall filing, “In rare circumstances, during certain braking events on dry surfaces at speeds below 25 mph, the vehicle may exhibit overly sensitive anti-lock braking system (ABS) control. In these conditions, if ABS falsely activates and a specific sequence of wheel movements occurs, the vehicle’s ABS system will continue to release the braking pressure in the vehicle’s service brake system. A release of braking pressure can cause the service brakes to have reduced stopping performance or become inoperative, increasing the risk of a crash.” GM said it is not aware of any injuries or fatalities associated with this condition.
The electronic brake control module software will be updated through an over-the-air (OTA) update or by a dealer, free of charge as required by U.S. safety regulations. Owner notification letters are expected to be mailed 23 September 2024. Owners may contact Cadillac’s customer service at 1-800-458-8006 or EV Concierge at 1-844-EV-CADILLAC (1-844-382-2345). GM’s number for this recall is N242453471. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov about NHTSA 24V589 or 24V-589.
Chronology
- On 31 May 2024 GM opened a product investigation into the subject condition after extensive engineering analysis and testing determined that two reports of minor accidents resulting from an alleged loss of braking may have been attributable to a software issue in the vehicles’ ABS.
- Reports relating to these vehicles were received by GM on 15 February 2024 and 12 March 2024.
- GM was also made aware of a separate potentially related field complaint, not involved in an accident, on 14 October 14, 2023.GM’s investigator retrieved and reviewed potentially related field data and identified no additional reports that may be related to the condition. GM’s investigation confirmed that the condition can only occur under very rare circumstances: during a false ABS event on a dry road surface at a speed below 25 mph, a specific series of wheel movements causes the vehicle’s ABS system to continue to command the release of brake pressure in the vehicle’s service brake system.
- On 1 August 2024, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall.
