The probe will also affect the GMC Acadia and the 2025-2026 Cadillac Celestiq and Optiq units. It also affects **Honda Motor Co. Ltd.**‘s (NYSE:HMC) 2024-2026 **Acura** ZDX and the 2024-2026 Honda Prologue EVs. The issue stems from the company’s e-boost brake-by-wire system, which replaces hydraulic systems with electronic sensors and actuators and could suffer from spindle fractures in the eBoost system, the report said. GM, in the report, said 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,” but NHTSA’s ODI says it received reports that “allege an immediate loss of brake assist functionality as opposed to the loss occurring after the vehicle comes to a complete stop.” ## Engine Failure In a separate investigation, NHTSA said it received reports of engine failure post-recall on multiple 2021-2026 GM Models equipped with the L87 engine. The recall, which affected 597,630 trucks and SUVs in the U.S. and warranted an oil viscosity change or engine replacement, was issued in April last year. “ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement,” the NHTSA filing said, while GM received 6,953 complaints related to the recall. **Read Also: Tesla Recalls Nearly 3 Million EVs in China Over Door Releases That Could Trap Occupants** *Check out more of Benzinga’s Future Of Mobility coverage by* following this link. *Photo Courtesy: Jonathan Weiss on Shutterstock* ### Related Stocks - [F.US](https://longbridge.com/en/quote/F.US.md) - [F-B.US](https://longbridge.com/en/quote/F-B.US.md) - [F-D.US](https://longbridge.com/en/quote/F-D.US.md) - [GM.US](https://longbridge.com/en/quote/GM.US.md) - [F-C.US](https://longbridge.com/en/quote/F-C.US.md) - [FRDD.US](https://longbridge.com/en/quote/FRDD.US.md) - [FRDU.US](https://longbridge.com/en/quote/FRDU.US.md) - [HMC.US](https://longbridge.com/en/quote/HMC.US.md) - [TSLA.US](https://longbridge.com/en/quote/TSLA.US.md) ## Related News & Research - [Weekly Recap: 223,472 F‑150 fuel‑tank recall and Ford (F) to own US plants](https://longbridge.com/en/news/298909917.md) - [Ford Recalls More Than 223,000 Trucks Over Fuel-Tank Issues](https://longbridge.com/en/news/298915322.md) - [General Motors (GM) Reaches New Unifor Deals, Is It Still Below Fair Value?](https://longbridge.com/en/news/298944691.md) - [Ford to recall about 223,500 US vehicles over fuel tank issues](https://longbridge.com/en/news/298798512.md) - [GM plans U.S. battery development as Trump's DOT attacks Ford for China ties](https://longbridge.com/en/news/298807463.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
