Automatic Emergency Braking problems of the 2023 Cadillac Escalade

Roads were dry. Sunny conditions. Driving approximately 55 mph in fast lane. Vehicle brakes locked up for approximately one second. There was no collision warning and no vehicle in front of us. We pulled over to disengage all collision and emergency brake functions. Driver and passengers were all shocked and had pain from tension in neck and back. Had roads been icy this could have led to a multiple vehicle accident with severe injuries or fatalities.

Vehicle was running with the driver side door open and driver out of vehicle. The vehicle slipped out of gear and reversed quickly. Driver went to get back in while moving backwards to try and stop vehicle. The driver got smashed between the garage and vehicle door. The vehicle door hyperextended and caused damage/injury to driver. The emergency brake did not come on until after the accident. Prior to this happening recalls were not preformed due to gm advising us that our vehicle was not next to get it done. Throughout ownership the vehicle has slipped out of gear two other times. We took it in each time and were told it shouldn’t happen again and they could not replicate. Gm did an inspection after and fixed recalls and told us they would not assist us with damage or any compensation.

My 2023 Cadillac Escalade vehicle broke down while I was driving on the highway this past Wednesday. While driving at highway speeds, the transmission unexpectedly shifted from drive (d) to neutral (n), and after that, I was unable to shift back to drive or start the vehicle. The car was then towed to Cadillac of silver spring in maryland for further inspection. I was informed the engine may be locked, but other technicians suggest it could be an ecm or electrical issue. The vehicle is still under warranty and only has 12000miles.

On [xxx] my 2023 Cadillac Escalade super cruise VIN: [xxx] with approximately 9600 miles failed to operate in a safe manner and has malfunctioned. The vehicle has been well maintained and follows all manufacturer specifications. It is a lemon. The engine seized while operating on the highway. The vehicle lost speed, there was a crashing boom sound, followed by extreme shaking as grinded to a halt. It was extremely challenging for the driver to maintain control. The dealership confirmed the engine will not turn over, they removed the oil filter and examined the oil sample from it. The sample showed signs of metal, a clear indication of an internal failure. The procedure now is to order a new engine, radiator, oil cooler lines and all one time use components of the fuel injection rails all seals, gaskets and bolts required by general motors. In addition, the emergency braking system did not engage. The onstar system emailed me the night before a clean bill of health with their diagnostic app. There were also no check engine lights prior to using the vehicle. Our use of the vehicle has been impaired, the market value has dropped, and there are obvious safety concerns in placing my family in this vehicle. My research online indicates this is a known issue, however no safety recall has been issued. Police arrived on scene to assist in tow. Police station was boxford, MA. A report has yet to be completed. I look forward to your prompt response and resolution to this matter. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
