General Motors, LLC is recalling certain 2024-2025 Buick Envista, 2024-2026 Buick Encore GX, Chevrolet Trailblazer, and 2025 Chevrolet Trax vehicles. The rearview camera screen may display a distorted or blank image.
While driving my 2025 Buick Encore GX Avenir, I experienced a sudden, catastrophic electronic and mechanical failure. Without warning, the brake pedal became extremely stiff, requiring massive physical effort to slow the vehicle down. Simultaneously, the dashboard displayed warning lights indicating that both the StabiliTrak system and the Power Steering system were disabled, causing a sudden loss of steering assist.The vehicle was towed via Buick Roadside Assistance to Ewing Buick in [XXX]. This simultaneous failure of braking, steering, and stability control represents an extreme safety hazard. The vehicle is currently at Ewing Buick, who is the dealership that sold me the vehicle in October 2024. The failure was accompanied by the warning lights on the dashboard at the same time of brake failure. I am a liver transplant and I bought this car so that I would have a safe vehicle I am now concerned because of possible blunt trauma to my abdomen if I have an accident.

The contact owned a 2025 Buick Encore GX. The contact stated that while driving at an undisclosed speed, the GPS failed to operate properly. Additionally, the air conditioning system was inoperable. The contact stated that while driving in the heat, the contact to briefly became unconscious. Due to the failure, OnStar was contacted to providing GPS assistance. After arriving to the destination, the navigation system started operating as designed. The dealer was contacted and diagnosed the vehicle with engine under-boost failure, loss in communication with the telematics communication interface control module, an open ethernet bus, an auxiliary heater command low voltage, lost communication with the inflatable restraint sensing and diagnostic module, and loss of communication with the direction camera control module. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 20,000.

Sealed transmission found "bone dry" at approximately 13,000 miles. No consumer-accessible dipstick. Complete transmission failure January 2, 2026. Second complete powertrain failure March 14, 2026, nine days after first repair completed. Symptoms on second failure (loss of power, hollow tumbling sound) consistent with engine bearing/connecting rod failure matching Cook et al. v. General Motors (Case No. 1:26-cv-00229, D. Del.) covering 1.2L/1.3L turbo engines. Dealer diagnosed "battery issue" on second failure and provided indefinite loaner. Vehicle purchased June 2025. Two failures within 9 months and 13,000 miles on a sealed powertrain system the consumer cannot inspect.

nStar remote diagnostic system returned five false-negative results across two confirmed mechanical failures. January 2, 2026: two diagnostics at 5:50 PM and 5:53 PM returned "No Error Code Found" while the transmission was actively failing. At 8:39 PM, the system identified P0700 and P2714 (Transmission System Failure, "Service within 1 day"). March 14, 2026: two diagnostics at 11:14 AM and 11:17 AM returned "No Error Code Found" while the vehicle could not exceed 20 mph on a highway. OnStar agent instructed a permanently disabled driver with a [XXX] passenger to continue driving during the first failure. GM issued a September 2025 TSB for "Loss of OnStar Connectivity" affecting all makes. FTC entered a 20-year consent order against GM/OnStar in January 2026. The Muhammad v. General Motors class action (E.D. Mich.) documents identical OnStar false negatives before engine seizures on the 6.2L platform. OnStar's diagnostic system appears unable to detect powertrain failures in sealed components across multiple engine platforms.

Second complete powertrain failure on March 14, 2026 at 13,993 miles, nine days after first repair (complete transmission replacement for bone-dry sealed transmission). Symptoms: sudden loss of power on highway (unable to exceed 20 mph with accelerator fully depressed), hollow sound, noise described as "like a rock tumbling around inside." OnStar diagnostics returned "No Error Code Found" twice (11:14 AM and 11:17 AM) during active failure. Dealer (Loveland Buick GMC) diagnosed "battery issue" but provided indefinite loaner with no return date. Symptoms are consistent with engine bearing or connecting rod failure matching Cook et al. v. General Motors (Case No. 1:26-cv-00229, D. Del., filed March 4, 2026) covering 1.2L/1.3L turbo engines in the Buick Encore platform. Complaint alleges GM knew about defect "since 2022, if not earlier" and instructed dealers to tell consumers vehicles are "operating normally." First failure involved sealed transmission running with zero fluid. Skipped oil change after transmission repair (documented in GM Executive Resolution emails) may have allowed metal contamination to damage engine components. Requesting investigation into whether dealer's "battery" diagnosis was accurate or whether actual diagnostic codes indicate engine failure consistent with Cook v. GM class pattern.
