I am reporting a sudden, complete failure of the vehicle braking system. I was operating a black 2026 Buick Enclave (an Enterprise rental car which my husband, [XXX], rented from the Tucson International Airport fleet, Vehicle Fleet #XXX) with my two children in the backseat. We were traveling at the posted speed limit of 45 mph in the fast lane on [XXX], heading toward Costco. Without warning, the braking system completely malfunctioned. Half a dozen red warning lights illuminated and alarmed on the dashboard, including the primary "BRAKE" indicator. When I pressed the brake pedal, it completely stopped working and went dead. The electronic parking brake failed to engage as well. Fortunately, the vehicle immediately ahead of me cleared a green light at the intersection, allowing me to coast through before the light turned red. I safely steered across the slow lane onto the shoulder and pressed "Park," but the vehicle continued to roll. The vehicle only came to a complete stop when I turned the engine ignition completely off. This vehicle has an Iowa license plate (PYR149) and failed at around 28,128 miles. This matches the exact profile of the ongoing master brake cylinder cartridge seal failures documented in active federal litigation against General Motors (such as XXX v. General Motors LLC). This defect poses an immediate public safety risk across GM's 2025-2026 shared-platform vehicles (Enclave, Traverse, Acadia, Colorado, Canyon) and needs to be formally investigated for a 2026 fleet safety recall. I have contacted GM Corporate (Case Number XXX) and William Withington at Enterprise Corporate regarding this incident.

Driving home from work on interstate, 2 month old 2026 Buick enclave jolted and shut off completely while going 65mph. Barely pulled over safely to the left side (Oklahoma drivers). Restarted car, check engine light illuminated with messages of reduced engine power (limp mode up to 35mph) while stuck on highway, traction control and esc disabled. Was able to get off highway and limp to nearest GM dealer. They performed diagnostics 3 days later and replaced the fuel rail pressure sensor. It did not fix it. More codes according to dealer and they are involving engineers. Moving next week on military orders and car is still being worked on with no estimate of time to complete. Insanely concerning safety hazard for a brand new car to shut off on the highway. Could have died or killed others in accident. Unable to invoke lemon law yet but not comfortable driving the car again especially across the country on limited time.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
