Filed Oct 31, 2026 · Brakes, Engine · MI

On October 30, 2026, at approximately 3:10 PM, my 2009 Cadillac CTS experienced an apparent engine and brake system failure while I was operating the vehicle. The vehicle lost power, and I was unable to stop despite applying the brakes. The exact component or components that failed have not yet been identified. The vehicle is currently available for inspection by insurance representatives, mechanics, manufacturer representatives, or other authorized investigators upon request. The apparent engine and brake failure created an immediate safety hazard because I was unable to maintain control of the vehicle's speed or bring it to a safe stop. As a result, the vehicle struck utility power equipment near my residence. The incident placed me, nearby residents, pedestrians, and motorists at risk of injury. The collision also caused a power outage affecting homes in the surrounding neighborhood. At this time, the cause of the engine and brake failure has not been reproduced or confirmed by a Cadillac dealer or independent repair facility. The matter remains under investigation pending inspection of the vehicle and its components. The incident was reported to 911, and a police report was generated. The vehicle has been reported to my insurance carrier, USAA. As of the date of this statement, the vehicle has not yet been inspected by General Motors or a Cadillac dealer for purposes of determining the cause of the failure. Additional inspections may be conducted by insurance representatives, repair specialists, or other qualified parties. Prior to the incident, I did not observe any warning lamps, brake system alerts, engine warnings, or other messages that would have indicated an imminent loss of braking capability or engine failure. The failure occurred suddenly on October 30, 2026, at approximately 3:10 PM. The vehicle had recently undergone a 120,000-mile service inspection, and no issues were identified that would have suggested an imminent catastrophic failure.

The all wheel drive link is not working. This causes the stabilitrac and abs to go out leaving only rear wheel drive. With very little weight in the rear of the car, it is very difficult to drive in snow or rain conditions as the car slides very easily. This is the 2nd time it's happened.

Cadillac cts was rented, oct 1, 2009, at 9:00 pm, at charlotte airport. My husband was driving the cts home on josh birmingham parkway. I was behind him in our car. We were both on the right-hand side of the road, near the old dowd road overpass. My husband signaled me that he was moving to the shoulder to stop. I was right behind him, on the shoulder. He slowed to less than 5mph. I saw his brake lights. But, his car didn't stop. It continued to roll forward at a weirdly slow speed. Brakes? Then slowly, at a very slight angle, the right tire rolled off the shoulder. The rear tires followed. Steering? Off-road, it crosses the ditch to the right. His left front tire hits an aluminum barricade. The end is buried into the ground. The cts turned violently to the left. Wheels straddled the railing, "riding" it. It lurched as the undercarriage hit each post. Sparks showered down. Once all the tires were off the ground, the cts came to a stop. The wheels were still turning, as I walked up to his door. My husband was slumped over and unresponsive. His seatbelt was on. Airbags? They had not deployed. I called 911. 10 minutes later fire, emt and police arrived. I was in shock, so the police report had major errors. It claims the car "rolled-over." no! Claims the car left the road at 45mph and hit the barricade. No! That his death was caused by an unrelated medical condition. No! The coroner's official report clearly states the cause of death was due to "blunt force trauma from the accident".) the police officer who wrote the official report went on vacation for weeks. Report was never corrected by me. Gm analyzed sdm data (dec 2009). Their date for the accident was wrong, nov 1, 2009. They claim the sdm exonerates the cadillac cts. They blamed the accident on operator error. I know my husband was an exceptionally safe driver, expert mechanic and avid car enthusiast for 50 years.

At first, the car wasn't running straight. When I drove straight on an interstate, the steering wheel was about five degrees clockwise. Therefore, I went to the local cadillac dealer, [xxx], for a wheel alignment. After the alignment, the car ran pretty good, until it ran over a small bump on the road. When I ran over the bump, the car suddenly ran toward the right. I tried to turn left, but it didn't work for about half a second. After half a second, I controlled the car, and it worked fine. I made an u turn, and went to that place again, and it happened again. I went home, grab my meter and my thermometer, and went back to that place. The road temperature was 33.1 degrees, and there was no ice on the road. The bump was about 4 inches over the road. I took the car to the dealer next day, and they checked almost everything. However, they're unable to identify the problem. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
