2024 Cadillac Escalade engine problems

“I am reporting a 2024 Cadillac Escalade ESV equipped with the L87 6.2L V8 for review in connection with NHTSA Engineering Analysis EA26005 and Recall 25V-274 / GM N252494000. The recall remedy was completed on November 13, 2025 after the vehicle passed the L87 PicoScope test. The dealer performed the prescribed oil and filter change and installed the revised oil-fill cap. At that same visit, I reported vibration at 70-80 mph and unusually loud engine noise. Subsequent service records document continuing harsh vibration and loud engine operation, along with other drivability concerns. On May 9, 2026, after completion of the recall remedy, the engine shut off twice during the same trip: once while stopped at a red light and again while traveling at slow speed during a turn. No crash, fire or injury occurred. I reported the shutdowns and continuing symptoms to the dealer. The vehicle continues to experience worsening vibration, rough driving/operation and a grinding sensation. EA26005 was opened August 20, 2026 to investigate allegations of loss of motive power due to L87 engine failure after Recall 25V-274 remedies and also covers later-production L87 engines. I…”

“I was driving the vehicle into a XXX parking lot in [XXX] on Thursday XXX at around 7:00pm, and as I slowed to park, the vehicle completely died and the dash screens went dark. The vehicle would not restart. I was able to rule out quick fixes such as a battery or fuse issue and then had the vehicle towed to the closest Chevrolet/GMC dealership. The vehicle has been at the dealership since the XXX. On Monday, XXX the dealership informed me that the engine had seized and that this is the same known defect as recall NHTSA Campaign 25V274000. The dealership said the engine must be replaced for the vehicle to be operational.”

“I was traveling in the middle lane at the normal rate of speed approximately 70 mph. All of a sudden I see a message to press start engine button again. I pressed the button and nothing happened. We started loosing speed and I notice that the car had downshifted into neutral. We were unable to navigate safely to the side of the road before coming to a complete stop in the middle of a busy highway with cars travelling at a high rate of speed. I had two small children in the back seat. When the police arrived, they tried unsuccessfully to determine how to move the car into neutral to push it to the side of the road. There was no safe way to exit the vehicle OR move it. We contacted OnStar and they dispatched roadside assistance and ran diagnostic. No known issues were noted. I contacted corporate and they said there are NO KNOWN ISSUES with this make or model despite there being numerous reports of other drivers experiencing the exact same thing. This could have been a tragedy. This car is well maintained, low miles, and was purchased new. The vehicle is now at the dealership with undetermined issues. The police noted that this is a known issue that they have…”

“Engine has a subtle but noticeable squeaking and chirp sound from the engine when cold and it is noticeable when decelerating, you can hear it then as well. The engine also runs fairly rough for a Cadillac and when decelerating to a stop, the engine RPM will drop significantly run rough and then it will recover. It's been Cadillac and Cadillac says this is working as designed.”

“On August 17, 2026, at approximately 96,685 miles, my 2024 Cadillac Escalade ESV equipped with the 6.2L L87 V8 engine lost motive power while I was driving on Highway 101 in California. The vehicle stalled, I pulled over, and I was unable to restart it. The vehicle was towed to the dealer. The dealer diagnosed a seized engine that would not rotate, with metal contamination in the oil system and internal engine damage caused by a failed bearing. During teardown, the dealer specifically documented that the rod bearing failed and caused the engine seizure. This vehicle had previously received the GM L87 engine recall remedy on August 11, 2025, at approximately 47,987 miles. The dealer documented that the required PicoScope test passed and that the vehicle was operating normally at that time. The engine failure occurred approximately 48,698 miles after the recall remedy. GM subsequently replaced the engine under warranty. I am reporting this as a safety-related loss-of-motive-power event because the engine failed while the vehicle was traveling on a major highway and could not be restarted. I request that NHTSA consider this incident in connection with Recall…”

“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,…”
