  "account": "General Motors (GM) electric vehicles, including those produced in collaboration with Honda, are now under greater scrutiny from the U.S. auto safety regulator following hundreds of incidents, over 20 crashes or fires, and at least six injuries. The brake issues also affect some non-EV models, such as the Chevy Colorado, GMC Canyon, Buick Enclave, and Envision. More than 1 million vehicles may be impacted. The National Highway Traffic Safety Administration (NHTSA) began its investigation in April 2024 after receiving reports from 2023 Cadillac Lyriq owners. The Office of Defects Investigation (ODI) of NHTSA upgraded the probe to an \"engineering analysis,\" the highest level, indicating the agency is likely to demand a recall.\n\nInitially, owners reported a \"Brake System Failure\" message during start-up or when stopping. GM conducted internal investigations and concluded the problem stemmed from fractures in the spindle of its \"eBoost\" brake-by-wire system. However, ODI now states it has continued receiving reports of \"immediate loss of brake assist\" during braking, which could lead to longer braking distances and potentially increase crash risks.\n\nThe eBoost system, introduced in 2019 and gradually incorporated into more models, replaces the traditional mechanical link between the brake pedal and braking system with an electronic one. This design allows GM to adjust brake \"feel\" in various driving modes. GM has implemented the eBoost system in its popular EVs, including the Blazer EV, Equinox EV, Cadillac Lyriq, and Honda Prologue and Acura ZDX (made jointly with Honda). The Cruise Origin, an all-electric autonomous vehicle that GM discontinued in 2024, also utilized the eBoost system.\n\nOne reported crash involved a 2025 Lyriq driver who lost their brakes while attempting to park, causing the vehicle to over the curb, crash through a storefront, and come to rest amidst furniture and the store structure. Another incident involved a 2024 Blazer EV driver who had to deliberately steer the vehicle into a concrete curb to avoid a collision at an intersection.",
