I was driving with my children in tow. My ‘reduced acceleration light’ came on as well as my check engine light. Within minutes of these turning on, my car went into Limp mode (shifted in neutral) and would not accelerate and steering felt locked up. I quickly got off to the side of the road and turned off the vehicle. When I restarted, the vehicle would not go into reverse or any gear other than park. This was terrifying. Thankfully, the road I was on had a speed limit of 40; however, had I been on the GA 400 or I-285, my family could have been easily involved in an accident. I had the vehicle towed to the local Cadillac dealership. After a week, I am told it is a faulty Control Valve Body and that there is no ETA on when this part with be available. The tow truck driver stated I was the 3rd Escalade driver in the last two weeks that the same issue had occurred. I will be reaching out to a lemon law attorney as well. This vehicle is still under warranty.
