2015 Cadillac Escalade engine problems

“My 2015 Cadillac Escalade 6.2L V8 with Active Fuel Management has had repeated lifter/valvetrain failures. On 10/2/2025 at approximately 109,536 miles, an independent repair shop confirmed a failed lifter on cylinder 3. The driver-side cylinder head was removed and all eight lifters on that bank were replaced along with a pushrod. On 9/9/2026 at approximately 116,689 miles, only about 7,153 miles later, the vehicle again developed severe shaking while driving. A different independent repair shop documented diagnostic code P0300, cylinder 1 low compression and misfiring, and noted that the lifters on that side had recently been replaced. Additional lifter-related parts, including lifters, a pushrod, guide and VLOM plate, were replaced. The shaking and misfire occurred while the vehicle was being driven, which concerned me because a sudden engine misfire or loss of normal engine performance could reduce power and affect safe control of the vehicle in traffic. Both failures were confirmed and repaired by independent automotive repair facilities. After the most recent repair, I returned the vehicle to the mechanic because it still felt different and had some…”

“The engine in my 2015 Cadillac Escalade failed unexpectedly at approximately 53,000 miles. Immediately prior to the failure, the engine developed a noticeable knocking noise, indicating a potential internal issue. While attempting to park in a public parking garage, the vehicle suddenly lost power and the engine shut down without any warning lights or alerts. This created a hazardous situation in a confined area with other vehicles and pedestrians, as I was unable to properly control or maneuver the vehicle. The sudden loss of power and complete engine shutdown significantly increased the risk of a collision or injury. The engine would not restart after the failure, leaving the vehicle disabled in the garage. Due to the confined space, the vehicle had to be removed using specialized towing equipment. The vehicle has been dealer-maintained since purchase, and I am the original owner. There were no prior major engine issues before this incident. The vehicle was towed to a dealership, where it was confirmed that the engine had seized and failed internally. I was quoted approximately $20,000 for a rebuilt engine replacement. This type of catastrophic engine failure…”

“Mileage: 90,406 2015 Cadillac Escalade Engine: 6.2L V8 EcoTec3 has experienced lifter and camshaft failure, and the vehicle is now stalling while driving, creating a serious safety risk. I transport my disabled child daily, and the stalls are unpredictable, putting us and other drivers at risk. This issue is consistent with the pending class action Harrison v. General Motors LLC, which alleges that 2014–present Cadillac Escalades with 6.2L AFM/DFM lifters can fail, causing engine noise, stalling, and catastrophic engine failure. The vehicle was service on 3/02/2026 at Riverview Chevrolet GMC for these issues and a complaint was summit to GM for these problems. Since after having the vehicles services I have had issues with the vehicle stalling while in progress and while driving causing me to be very scary that the vehicle will completely stall out or shut down on me while on the road driving causing an accident. Please help me resolve this unsafe matter. Thank You!”

“Within the last 20,000 miles this car has, and is now, been at the dealership 3xs for sudden lifter/camshaft failure. This last time almost caused an accident. One time the check engine light never even came on, two other times it came on as the car started slowing and shaking, so no notice as to what was about to happen.”

“Cadillac and GM have a know issue in the Escalade for faulty susp3nsion, with their MagRide system, and bad lifters. They use AFM/DOD to reduce the engine down to 4 cylinders and it causes the lifters to get stuck and damage the cam. I am one of thousands to experience these issues. GM need to be held responsible. Why. Are you putting this junk in 100k trucks? Why are we having to foot the bill to get rid of it? My car only has 112,000 miles. This is ridiculous. Please help.”

“The contact owns a 2015 Cadillac Escalade. The contact stated that while driving approximately 70 MPH, the vehicle experienced a temporary loss of automotive power. No warning light was illuminated. The contact was able to pull over to the shoulder of the roadway; however, the vehicle failed to restart as intended. The vehicle was towed to the residence and was then towed to a local dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was made aware of the failure. The failure mileage was approximately 170,000. The VIN was not available.”
