2026 Cadillac Escalade: engine knocking or ticking

Filed Oct 1, 2026 · Electrical, Engine · MA

I purchased a new 2026 Cadillac Escalade equipped with the 6.2L V8 engine and took delivery on XXX. At approximately 9,700 miles, the vehicle developed an engine-related problem and the check engine light illuminated. I brought the vehicle to Cadillac of Norwood in [XXX] on XXX During diagnosis, the dealership identified metal contamination in the engine oil. I was advised that, because metal was found in the oil, further internal diagnosis was stopped and the engine would need to be replaced. The dealership subsequently ordered a complete replacement engine. As of XXX, the vehicle remains at the dealership awaiting the replacement engine and has been out of service continuously since September 16. This is particularly concerning because the vehicle is approximately six months old and has fewer than 10,000 miles. An internal engine failure resulting in metal circulating in the oil at such low mileage raises concerns about premature engine failure and the possibility of loss of engine power if a similar failure occurs while the vehicle is being driven. Prior to this failure, I had also noticed an abnormal ticking noise from the engine. The vehicle has required multiple dealership visits since purchase for other concerns. I am submitting this complaint so the federal safety agency has a record of the premature engine failure and replacement on this 2026 Cadillac Escalade. I believe this should be evaluated for potential similarity to other reported 6.2L V8 engine failures in GM full-size SUVs and trucks.

I purchased a new 2026 Cadillac Escalade on July 27, 2026. Shortly after purchase, the vehicle began experiencing significant engine-related problems, including shaking, rough running, loss of power, knocking-type noises, misfires, and a check-engine light. The vehicle underwent three separate repair attempts for the engine-related concerns. During these visits, the dealer diagnosed and attempted to correct the misfire and related engine issues, including work involving the ignition coil/coil pack. Despite these repair attempts, the problems continued or returned. A fourth visit was then conducted as a final repair attempt. During this visit, a General Motors engineer became involved and attempted to diagnose and correct the vehicle’s continuing engine problems. Despite this additional manufacturer-level repair attempt, the underlying engine concern was not successfully resolved. The vehicle was essentially brand new when these problems began. After three repair attempts and a fourth final repair attempt involving a GM engineer, I remain concerned about the safety, reliability, and long-term condition of the engine because of the repeated shaking, loss of power, misfires, abnormal engine noise, and warning lights.

Started hearing a knocking sound from the engine Saturday. Stopped driving the car the rest of the weekend. Took to the Cadillac dealer today and was just told the car needs a new engine. This is unacceptable on 130k 2026 vehicle. Hopefully, you can apply severe pressure on GM to get this issue fixed once and for all.

The motor started making a ticking noise, then when we came to a stop, the motor died. I was able to get it started and get us home. As we made it home, the noise began to get worse. The next morning I planned to take it to the dealership. The car started and I began to drive. We entered the freeway and as traffic picked up, we came to a stop on the freeway. The engine died again. I was able to start it one more time and cotinued on until we got to the exit the dealership is on. At this point the car died again and we were unable to get it started. It left us stranded on the offramp. Car needed to be towed to dealership where it was discovered the engine had failed. Cadillac replaced the engine with a new one. This happened at 7100 miles.

I purchased a new 2026 Cadillac Escalade from AutoNation Cadillac West Palm Beach on July 27, 2026. At only approximately 375 miles, the vehicle developed serious engine/drivability problems and front/rear bumper alignment defects. The Escalade began shaking/stuttering, hesitating, experiencing inconsistent power, and making an abnormal knocking-type noise. The check-engine light illuminated. I took the vehicle to Delray Cadillac, where technicians found a cylinder 4 misfire and ultimately determined the problem involved the cylinder 4 lifter system. The repair required substantial internal engine work on an essentially brand-new vehicle. Cadillac replaced eight lifters, along with associated gaskets, bolts, guides, and related components. The engine was opened for the repair, and the technician inspected the camshaft/cam lobes and related valvetrain components before reassembly and testing. After receiving the vehicle back, I still notice abnormal power delivery. At approximately 45–55 mph, the engine intermittently hesitates and feels as though it struggles to maintain steady power, even though the check-engine light is currently off. This concerns me because major internal engine work was already required at only about 375 miles. The vehicle also has visible front and rear bumper alignment problems. The rear bumper protrudes outward instead of sitting flush with the body, and the front bumper also appears misaligned. These issues were reported to Cadillac. I am reporting this because a new vehicle requiring major valvetrain/engine repair at approximately 375 miles, followed by continued hesitation and inconsistent power, may present a safety risk during acceleration, merging, or highway driving.

Driving on freeway, engine starting knocking loudly and completely failed. I blew an engine on my 2023 escalade esv as well. Seems like the recall might need to be extended to the 2026 models as well.

My Escalade had just been into the dealer because the battery died at only 4200 miles. I drove away and after 10 minutes, I was getting warning messages that the engine was overheating and to turn the vehicle off immediately. I had to pull over on the freeway while listening to my engine knock and click. I eventually got it back to the dealer where they were unable to turn the car on and unable to determine the issue other than telling me it’s something with the engine.
