NHTSA Complaint #11699018 — 2026 CADILLAC LYRIQ

**2026 - Cadillac Lyriq One-Pedal Driving and Brake Defect** On November 4, 2026, at approximately 9:30 AM, I was driving my 2026 Cadillac Lyriq using the one-pedal driving feature while going below 20 miles per hour. Suddenly, the vehicle accelerated unexpectedly. I lifted my foot off the accelerator, but the car did not slow down despite the one-pedal driving being enabled. Within a few seconds, various warning lights appeared on the dashboard, including messages such as "One-Pedal Driving Unavailable," "Brake Assist Off," "Auto-Hold Unavailable," and "Steering Assist is Reduced - Drive with Care." Additionally, warnings for "Service Headlamps," as well as red or yellow indicators for "Parking Setting," "ABS," and "Ready," were activated. I made several attempts to apply the brakes, but they did not respond. I even tried to engage the parking brake, which also failed. Fortunately, I was lucky enough not to hit anyone or run over any curbs during this incident. The 2026 Lyriq that I purchased has fewer than 500 miles on it and has been at the dealer service center for over two weeks. This is a significant safety concern, and I believe Cadillac should take immediate action to address this issue.
