2023 Cadillac Escalade Fuel system Problems

I was driving and the vehicle stopped accelerating and the gear was in neutral. I pulled over and turned the car off then attempted to turn it on, but it would not turn over. All electrical was on, but the car would not start. This same thing happened two days prior twice within 10 min. of each other, but I was able to start the car those times. Due to the speed suddenly declining and being unable to accelerate on a two lane road with cars behind me; it could have caused a serious accident. It has not yet been confirmed by a dealer, but this is a known recall for this vehicle that was listed as complete prior. There was no warning lamps or messages prior to the failure. The first noted incident happened on 8/10/26.

My vehicle lost full engine propulsion going 70mph on the highway. We were blocking lanes of traffic and lost speed at a very rapid pace. No engine or warning light came on before the car lost engine and shifted into neutral. We called 911 and the California Highway Patrol had to assist in us not getting hit from behind as our car was disabled and would not restart to move off of lanes of traffic.

Sudden loss of propulsion at highway speeds - 2023 Escalade. We easily could have been killed. I drive a 2023 Cadillac Escalade that I purchased from Motor Werks Cadillac in [XXX] . It was very expensive. The car has under 33k miles on it, off memory.I informed the dealer I would be taking the car on a family vacation road trip from [XXX] to [XXX] (for spring break), and requested they perform any necessary preventative service on it to ensure it was in perfect shape to make the trip. They performed the service (basic air filter change etc) and returned the car to me two days before I packed my family [XXX] and [XXX] daughters and wife) into the car and began the journey. After driving less than three hours, the engine completely and suddenly died, without warning, while we were traveling at 75 miles an hour on the highway in the left lane in the middle of rural [XXX] . At the same time all of the electronics in the vehicle died as well. It was an extremely dangerous situation because the road is heavily trafficked by semi trucks, which I was barely able to avoid as I attempted to coast across all the lanes of traffic to get onto the shoulder of the road on the right hand side. Because the car was without propulsion, I was not able to get fully onto the shoulder, but mostly. This left the car in a precarious position because the semi's that we're driving by could easily have hit the car had they not been careful and veered slightly to the left. We easily could have been killed. There's more to the story, like the dealer telling me Cadillac is aware that catastrophic engine failure at highway speeds is a known issue impacting Escalades around the country, and including significant mental trauma that my children experienced by being stranded on the side of the road for several hours in the dark in a car that had no engine, no electronics and no heat.

Vehicle: 2023 Cadillac Escalade (VIN: [XXX] ) Dealer: Cadillac Pasadena Case Number (GM Corporate): XXX Refusal to perform a mandatory Federal Safety Recall remedy. Details: 1. My vehicle is currently under Safety Recall XXX(L87 Engine Loss of Propulsion). I experienced a loss of propulsion and brought the vehicle to Cadillac Pasadena. 2 The dealership technician confirmed the engine is exhibiting "abnormal noise (lifter clatter on both banks) and active misfires." 3 The dealership claims they cannot complete the mandatory PicoScope diagnostic test for the recall because the engine condition (misfires/noise) interferes with the equipment. 4 Under GM Special Coverage XXX, if the engine cannot be safely tested due to internal mechanical failure within the recall population, GM is mandated to cover the diagnostic teardown and full engine assembly replacement at no cost to the consumer. 5 The dealership is refusing to authorize the teardown under the GM Special Coverage code and is instead pressuring me to pay myself. 6 The dealership has stopped responding to my written inquiries (sent March 18th and 19th) and refuses to provide a loaner vehicle, despite the vehicle being officially "unsafe to drive" due to the open safety recall. I am asking you to requre Immediate authorization of engine teardown and full engine assembly replacement under GM Special Coverage XXXat $0 cost to me, and provision of a loaner vehicle as required for safety recall grounding.

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.

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 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.

Sep 5, 2025

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.

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.
