Manufacturer Telematics Problems of Buick Enclave

The contact owns a 2025 Buick Enclave. The contact stated that while driving 10 mph, the brakes suddenly failed with the "brake assist failure" and "service esc" warning lights illuminated. After restarting the vehicle, the contact received a secondary message that the vehicle would be limited to 45 mph, with an instruction to press the brake pedal very hard. The contact stated that the brake pedal felt extremely squishy and unsafe to operate because it failed to operate properly. On a separate occasion, the vehicle shut off without warning, with a very loud clicking sound coming from the vehicle. After several attempts, the vehicle was restarted, and the audio and electronics functioned as needed for minutes of driving. The vehicle was taken to the dealer for the electrical failure, and the technicians attempted a telematics control module reprogramming. The dealer stated that the module was already updated but discovered that the module was no longer communicating, which created several issues. After restarting the module, the vehicle was temporarily repaired. The vehicle was taken back to a local dealer but was not yet diagnosed or repaired. The failure mileage was 38,000.
