General Motors (GM) has issued a recall for over 20,000 Cadillac Lyriq electric SUVs, fearing a software bug could trigger an inadvertent activation of the anti-lock braking system, hence increasing the probability of accidents. The recall was announced subsequent to National Highway Traffic Safety Administration submissions.
Primarily, the recall affects 2023 and 2024 models, totaling 21,469 vehicles in the U.S, and an estimated 24,200 across North America. A large portion, 87%, are 2024 models crafted at GM’s Spring Hill assembly line in Tennessee. GM discovered a fault in the software governing the vehicles’ electronic braking systems, which could render the brakes inoperative. GM urges affected owners to park their vehicles outside and away from structures until a dealer updates the software.
The software bug occurs primarily when the driver brakes on dry surfaces at low speeds, under 25 mph. Braking efficiency subsequently deteriorates, and in extreme cases, the braking system could become nonfunctional entirely, thus increasing crash risks. It is, therefore, paramount that this issue be rectified promptly. All users need the requisite software patch and comprehensive update instructions, to mitigate risks.
Cadillac Lyriq SUVs recalled for software bug
A review of the software development process should also be initiated to forestall similar future problems.
GM plans to correct the defect by overhauling the Electronic Brake Control Module software in the recalled vehicles. Owners in compliance with GM’s terms of service can receive the software updates wirelessly. Additionally, appointments for manual application may be scheduled at GM dealerships.
In a press release, GM spokesperson, Bill Grotz, stated that an effective solution had been agreed upon. The new software will be wirelessly sent to most of the recalled vehicles within the month. GM further assured customers that the Lyriq’s production had not been hampered by the recall and that solutions were already being administered at dealerships.
The software bug was found after GM observed minor incidents potentially linked to brake failure. The company’s attention was drawn to the issue further by a car owner’s complaint in October 2023. This recall is among several software-related problems new GM electric vehicles have encountered lately, including Cadillac Lyriq and GMC Hummer EV models. Importantly, no injuries or fatal incidents related to the defect have been reported to date.
