On 6/16/24 While driving on I95 the car started making a flapping noise and the car started to lurch and buck. No warning lights were on at the time. I pulled over and turned the car off and could not get it to restart right away. After a few tries it did turn on and the engine light stayed on but the car would not shift into gear. The car had to be towed and we were told there was a total engine failure.

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)

INCIDENT: I was driving on the highway when I heard a strange "whistling noise." Thinking the noise originated from an old van in front of me, I passed it. The noise grew louder; the vehicle slowed very suddenly and, I pulled to the side of the road. The "low oil pressure" light came on just as the engine entirely blew. There were NO OTHER WARNING LAMPS, MESSAGES or OTHER SYMPTOMS. On-Star did not send roadside assistance for six hours and the battery died from extended use of the emergency lights. DANGERS: Experiencing catastrophic engine failure while driving on a highway presents obvious dangers as does sitting roadside for six hours (with a dead battery and no emergency flashers). INSPECTION: The G.M. Dealer (manufacturer representative) inspected the engine and confirmed that it was a catastrophic engine failure, requiring a new engine. The issue was also reported directly to G.M. The engine core, if need of further inspection, is likely either at the dealer, G.M., or a GM remanufacturing facility.
