2023 Cadillac Escalade

Prior to purchasing my 2023 Cadillac Escalade, I was informed the vehicle had been subject to an engine recall. The dealership told me the corrective action was changing the oil from 0W-20 to 0W-40, replacing the filter, and updating the oil cap. I was assured this resolved the issue and that I should not experience future problems. Based on those assurances, I purchased the vehicle in October 2025 with approximately 25,000 miles. About nine months later, the engine shut off while I was stopped at a traffic light. The vehicle automatically shifted into neutral and turned off. I restarted it and continued driving. The exact same incident occurred again a few days later. I brought the vehicle to a Cadillac dealership for inspection. After several hours of diagnostics, I was told they could not find any issues and that the vehicle appeared to be operating normally. Two days later, while traveling approximately 75 mph on the highway with my family, including two young children, a warning message appeared instructing me to restart the vehicle. At the same time, the vehicle shifted into neutral and lost propulsion. I pulled to the shoulder and restarted the engine, which struggled to start and ran very rough. After resuming travel, the exact same failure occurred again within minutes at highway speed, forcing me to pull over a second time. Concerned for my family's safety, I exited the highway and drove local roads. The vehicle was returned to the dealership. An oil sample was sent to a GM-approved laboratory, and I was later informed that elevated levels of metal contamination were found in the oil. GM subsequently authorized a complete engine replacement. I am submitting this complaint because the recall remedy I was told would resolve the issue did not prevent a major engine failure. The vehicle shut off twice at stoplights, passed a dealership inspection, and then lost propulsion twice at highway speeds. This presented a significant safety risk to my family and

The engine/powertrain malfunctioned on my 2023 Cadillac Escalade at approximately 29,434 miles, ultimately requiring complete engine replacement. During the engine repair, the Cadillac technician also discovered that the transmission cooler lines were leaking fluid. The dealership replaced all of the affected transmission cooler lines as part of the repair.The original failed engine was removed by the Cadillac dealership, so I do not know whether GM/Cadillac retained it. The failure involved the vehicle’s engine and created concern about the possibility of sudden loss of propulsion or engine failure while driving. Because this is a large vehicle routinely operated on public roads and highways, an unexpected loss of engine power could significantly reduce my ability to safely accelerate, merge, or move the vehicle out of traffic. Fortunately, I brought the vehicle in for service after noticing the abnormal engine noise before a complete failure occurred while driving. Yes. Heritage Cadillac inspected and diagnosed the vehicle. The dealership documented my complaint of a “weird noise on start up” that continued until approximately 10 MPH. The technician removed the valve covers and inspected the rocker arms and pushrods. The dealership ultimately determined that an engine replacement was necessary and replaced the engine under warranty. Yes. The vehicle was inspected and repaired by Heritage Cadillac, an authorized Cadillac dealership. The dealership diagnosed the engine issue and replaced the complete engine. During the repair process, the technician also discovered leaking transmission cooler lines. I did not receive a warning lamp or dashboard message alerting me to an engine problem. The primary symptom was an abnormal engine noise shortly after startup that continued during initial acceleration to approximately 10 MPH. This prompted me to bring the vehicle to Heritage Cadillac for inspection. The dealer documented this symptom on the repair order.

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.

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.

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.
