This Problem Across All Years
While driving about 60–65 mph westbound on NY Route 17 near Exit 125, a warning message appeared on the dashboard reading “Restart Engine.” Within seconds the vehicle lost all propulsion, steering assist, and braking power. Pressing the accelerator did nothing and the car began rapidly decelerating in live highway traffic at night. I struggled to steer into the shoulder with great effort because the steering and brakes had become extremely heavy. Once stopped, the engine would not restart — there was no crank and no response when pressing the start button. The vehicle was later towed to the dealership for inspection. This failure occurred without any prior warning other than the single “Restart Engine” message that flashed moments before the loss of power. There were no check-engine lights, alerts, or performance issues beforehand. Unity Chevrolet Cadillac confirmed that the engine had seized and replaced the entire engine assembly, starter, and battery under warranty. The vehicle remained out of service from August 7 to August 22 2025. This sudden failure created a severe safety hazard — a complete loss of propulsion, steering assist, and braking at highway speed could easily have resulted in a high-speed collision.
On Friday, September 5, 2025, while driving with my family, the vehicle suddenly stalled while in motion. There were no warning lights or error messages before the failure occurred. While traveling at normal road speed, the vehicle instantly lost propulsion, steering assist, and braking power, leaving me without control in live traffic. For several seconds I was unable to steer or slow down normally — it was an extremely dangerous situation. The vehicle briefly restarted twice, then completely died and could not restart again. I had to pull over to the shoulder and call for assistance. This repeated sudden loss of power while driving, without any prior warning lamps or messages, creates a severe risk of collision or injury to occupants and others on the road. The vehicle’s unpredictable failure to maintain propulsion or braking control is unsafe and unacceptable.
On Wednesday, September 3, 2025, while driving in regular city traffic, the vehicle suddenly lost propulsion without any warning or dashboard alerts. There were no warning lights, messages, or abnormal sounds before the failure occurred. The vehicle instantly shut down while in motion, causing a total loss of acceleration power and leaving me stranded in the middle of traffic. This occurred the second time I was driving the car after prior service, and the vehicle again stopped completely, forcing me to pull over and contact OnStar roadside assistance. This was the second major propulsion failure in a short period, each time occurring unexpectedly while driving. The repeated sudden shutdowns without warning present a serious safety risk and indicate an unresolved defect in the vehicle’s electrical and propulsion systems.
On Sunday, September 14, 2025, while driving northbound on the Palisades Parkway at approximately 11:30 PM, the vehicle suddenly lost all propulsion without any prior warning. I was traveling around 45– 50 mph when the dashboard lights began flashing, and the vehicle shut down completely in active highway traffic. All systems—including power and acceleration—dropped instantly. I was unable to maintain speed and was not even able to brake, and had to fight to steer the vehicle safely onto the shoulder as it slowed down. There were no warning lamps, messages, or irregular behavior prior to the failure. The shutdown occurred instantly and without cause, creating an extremely dangerous situation on a dark highway late at night.

I was in car. I just stepped out of the car its stop working car couldn't start. I need to get started to start the car. It happens a lot. I went to caddilac dealer service they everything good. This car for work not luxury. I drive Uber and always on road. So I afraid something will happen. I want to change this car for new without recalls. Thank you

All cadillac dealerships are refusing to inspect the vehicle to ensure engine is safe despite specific instruction in recall that dealership will and determine if vehicle is affected. If not affected they will change oil viscosity. Dealerships are refusing to perform this test and change oil.

I was driving to work at 45 miles/hour and the car's engine cut out. My life was at risk because the car cut out without warning while I was driving. When the car stopped working, I called the dealership, and they came to take the car away. The car didn't give any warning or display any warning messages beforehand. The car has been at the dealership for a month and they still haven't repaired it.

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.
