2024 Cadillac Lyriq Steering Problems

While slowly turning into a parking space at approximately 1 mph (?) the vehicle unexpectedly accelerated. The vehicle mounted the curb, and struck a a parked car and hit a brick retaining wall, causing damage to both. This all happened within a few seconds and there were no warning lights or messages before or during the accident. I was not injured and there were no other people present. The police were called and inspected the damages. The insurance company was contacted due to damages. No one was in the parking lot at the time. The manufacturer was notified and will inspect the car for cause/failure.

- Software failure resulted in loss of steering control, speed control, and brakes became unavailable. I was on highway car was at 65 mph and then I got a bunch of error messages mentioned below- 1) Steering assist not available 2) AWD is disabled 3) Headlamps not available 4)Service brake assist And then I was not able to brake the car, and steering became highly unresponsive. I took my foot of gas and let the car roll for 1 mile before stopping safely on shoulder, from where I called Cadillac for support (they towed the car back), since error didn't resolve after stopping or rebooting the car. I took screenshot of these errors after stopping and attached them in this email. - Yes it put safety of me, my passenger, and other vehicles at risk, loss speed and steering control you have cause me to hit any other car. - Yes problem is reported to manufacturer, car is in service. - Vehicle is with Service, since no one got hurt, we didn't involve police. - No prior message or warnings we recieved, all errors come as soon as the issues appear.

The steering wheels sometimes don’t control the wheel and it is wobble.
