On Nov 16-17, 2025 we had GM recall work done - it was an manufacturers defect in connecting rod & crankshaft that can cause bearing failure or sudden loss of propulsion. The escalade ran fine since then, other than the HUD not working on the windshield. We had the oil changed on Sept 17, 2026, and they ordered the part for the HUD. On October 10, 2026, with this 2024 escalade, we were heading to SC towing an enclosed trailer with a motorcycle inside. 35 minutes into our drive on an interstate, the escalade started making a loud grinding noise, like the engine was revving up, then the engine cut out. We were able to coast to the shoulder and park it. It would not start back up. We called Onstar and ordered a tow, that took 4+ hours to arrive. The tow dropped it off at the dealership. The service rep said it's probably the engine (and he has 2 other escalades here with the same problem), but they cannot look at it until Monday. We tried to get a loaner through the dealership so we could continue our trip, and they were not able to accommodate us.

We bought my 2022 Cadillac Escalade brand new in mid July from a Cadillac dealership.. fast-forward early September ( I remember because my son was in a wedding at the end of September) and we were shopping for my son dress shoes. My son and I were tired after a long full day of shopping, and walked out to a dark parking lot only to find my brand new car would not start. It was about 9 PM, I do remember the exterior lights would come on, but the engine would not start. And then would not turn off. We waited until midnight (it was very scary)for roadside assistance to pick up my car tow it to the dealership. Then had to call an uber because my husband was out of town. Come to find out they diagnosed my vehicle, in a module had to be replaced.

On 8/25/2026, my 2024 Cadillac Escalade with the 6.2L V8 suffered a sudden loss of propulsion at approximately 49,754 miles. While my husband was driving and preparing to enter the highway, the vehicle went into Neutral and lost propulsion. He heard a loud banging noise, the low-oil warning illuminated, and the check-engine light began flashing. I later looked in the Cadillac app and saw code P0016. The engine then completely seized. The vehicle was towed to Sewell Cadillac. The dealer documented that the engine would not crank or turn manually, found metal/debris in the oil and internal bearing/rod damage, and replaced the complete engine. We picked up the Escalade on 8/29/2026 at approximately 49,779 miles. After only 127 miles, at approximately 49,906 miles, I experienced another loss of propulsion while driving. The vehicle unexpectedly went into Neutral and shut off. I was able to restart it and safely move it, but it shut off again. There were no warning lights after restarting. The vehicle was towed back to the dealership. On the second repair order, the dealer documented the complaint as “vehicle turned off and went to neutral.” They found code U3000, documented “ECM software out of date” and “ECM software malfunction,” and reprogrammed the ECM using GM’s SPS system. The repair order identifies this as a “REPEAT REPAIR” related to the prior engine replacement. As far as I know, my VIN was not included in the applicable 6.2L engine recall, and I was not informed by the dealership about the known 6.2L engine issue. I am reporting this because the vehicle has experienced two sudden loss-of-propulsion events in less than 50,000 miles, including one only 127 miles after complete engine replacement. I am concerned this vehicle is unsafe to drive.

Engine failed while driving down the highway at speed. Just shut off. Very dangerous. No power had to pull over. Vehicle would not start agin. Said low oil pressure. Had it towed to the dealership. Complete engine failure and had to have the motor replaced. After replacement engine still does not feel right and transmission acts up as well. Complete piece of junk for how expensive these vehicles are. Scary, dangerous and do not trust this vehicle anymore. Stuck with an unsafe piece of junk that's unreliable. Please help. New motor is exactly the same as the other one so it's going to fail again. It stays at the dealership instead of my driveway. People are getting screwed. Some kind of compensation needs to be done for us with these issues. Completely unfair.

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.

While driving my 2016 Cadillac Escalade, the vehicle experienced a sudden mechanical failure associated with the engine and charging system. Upon failure, the vehicle displayed warning indicators including a “low battery” warning and emitted a burnt smell. The engine subsequently failed completely. Diagnostic findings stated: engine would not crank, oil contained metal contamination, crankshaft seized, complete engine replacement required. The estimated repair cost is approximately $14,000–$18,000. This failure occurred despite regular maintenance, including an oil change completed on January 18, 2026. This sudden failure created a major safety concern because the vehicle lost reliability while being operated on public roads. A sudden engine This sudden failure created a major safety concern because the vehicle lost reliability while being driven the vehicle it completely quit and shut down in rush hour traffic causing an unsafe situation for me and my family. This sudden failure created a major safety concern because the vehicle lost reliability while being operated on public roads. A sudden engine or charging-system failure at driving speeds could have caused a crash, loss of steering assistance, loss of power, or stranded occupants in traffic. I contacted GM/Cadillac seeking assistance through the goodwill process, but assistance was declined despite the catastrophic nature of the failure. I am filing this complaint because I believe there may be a broader defect involving the engine, crankshaft failure, lubrication system, or charging system components in this vehicle platform. I request investigation into similar failures affecting Cadillac Escalade vehicles with the 6.2L engine.
