Sudden Acceleration. -I was driving on a highway. I accelerated to pass a truck and when I took my foot off the accelerator the car continued to gain acceleration. The gas pedal had returned to a normal position but the car was still accelerating. I had to put full force on the brakes to get the car to stop. One of my passengers noted that there were flames around one of the brakes. I turned the car off and we waited approximately 45 minutes for the brakes to cool enough to proceed without further incident.

Steering, suspension, wheels

I purchased the 2025 Lyriq new on May 11, 2025. On May 30th with 5400 miles on the car, the front right wheel tie rod snapped off while driving causing the wheel to turn sideways. I was making a turn on a secondary sheet when it happened and was able to pull to the side of the road. Had I been driving on the highway at the time, I could have been killed or hurt another driver. I had the car towed to MacMulkin Cadillac on June 1. The dealership noted that it was bad welding and the car showed rust and rot in that area. It will be 30 days this Monday and no one from GM has been out to investigate.

Electrical System, visibility/wiper
04/28/2025
The infotainment screen automatically adjusts its brightness based on readings from the ambient light sensor. However, during dusk and dawn, while conditions still appear relatively bright to the human eye, the sensor interprets the light levels as low and significantly dims the screen. As a result, the display can become so dark that it is nearly unreadable. This issue occurs even when the brightness control wheel is set to its maximum setting. The light sensor overrides the manual brightness adjustment, and the control wheel can only further reduce the brightness, not increase it. GM should provide an option to disable automatic brightness adjustment, or update the auto-brightness algorithm to prevent the screen from dimming excessively under such conditions.

Unknown Or Other

I am writing to report a series of alarming incidents involving my 2025 Cadillac, purchased on December 2, 2024. Within three months of ownership, I have experienced three separate occurrences that have caused me significant concern and physical distress. 1 Approximately two weeks after purchasing the vehicle, I was stopped at a red light. When the light turned green, I pressed the Pedal. Within three- 4 seconds, I felt a sudden impact from the rear, as if I had been rear-ended. However, upon inspection, there was no visible damage to my car, and the vehicle behind me was approximately 10 feet away. This incident was both confusing and distressing. 2 On a separate occasion, under similar circumstances, I was stationary at a red light. Upon the light turning green, I began to accelerate and once again experienced a sudden, forceful jolt from the rear. No vehicle was in close proximity behind me, yet the sensation was akin to a severe rear-end collision. The jolt was signific...
