Cadillac & Chevrolet EV Loss of Braking Defect Investigation

Current Investigations

General Motors Cadillac & Chevrolet EV Loss of Braking Defect

Scott Hirsch Law Group PLLC is currently investigating General Motors LLC regarding approximately 67,380 luxury and midsize electric vehicles—including 2023–2027 Cadillac LYRIQ, 2025–2026 Cadillac CELESTIQ, 2026–2027 Cadillac VISTIQ, and 2024–2027 Chevrolet Blazer EV models—for critical safety defects in the electronic brake control system. A software defect within the brake system control module can cause an unexpected software fault under specific driving conditions, leading to a sudden loss of hydraulic braking assistance, extended stopping distances, and severe crash hazards.

EV Drivers Face Sudden Loss of Braking Power and Dashboard Fault Warnings

Owners of Cadillac and Chevrolet electric crossovers and sedans rely on advanced electro-hydraulic braking systems for daily driving and regenerative braking integration. However, safety filings submitted to federal regulators reveal that internal software glitches can cause the Electronic Brake Control Module (EBCM) to disable power braking assist without warning. When hydraulic brake power fails, drivers must apply extreme force to the brake pedal to slow the vehicle, resulting in unexpected pedal travel, delayed stopping ability, and heightened risk of rear-end collisions or intersection crashes.

NHTSA Safety Recall Covers Over 67,000 GM Electric Vehicles

General Motors submitted a safety recall report to the National Highway Traffic Safety Administration (NHTSA Recall Campaign No. 26V-717 / GM Recall No. N262570900) covering 67,380 electric vehicles nationwide. While GM has developed a software update—deliverable either via Over-The-Air (OTA) wireless transmission or through an authorized dealership visit—many owners report confusion over update installation status, lingering brake warning messages, and anxiety over sudden braking loss at highway speeds. We are investigating whether General Motors manufactured and distributed these high-end electric vehicles with defective braking control software and whether affected owners are entitled to compensation for safety risks, vehicle downtime, and diminished value.
