The engine malfunctioned. On October 19, 2026, the dealership advised by telephone that the engine would need to be replaced. The specific internal component or cause of failure has not been provided. The vehicle is available for inspection upon request. 1. During highway driving, the vehicle hesitated while accelerating and did not respond as expected. The driver backed off the accelerator and observed a flashing check-engine light. Unpredictable acceleration created concern about safely keeping pace with traffic. Additional noises and an unusual odor later developed. The vehicle was parked safely. 2. Yes. The dealership evaluated the reported problems and advised on October 19 that engine replacement was necessary. Written diagnostic findings have not yet been provided. 3. The dealership evaluated the vehicle. No separate inspection by the manufacturer, police, insurance representatives, or an independent service center is known. According to the records available to us, the vehicle was driven only TWO miles in connection with the dealership’s Certified Pre-Owned (CPO) inspection. This raises concern about whether the inspection adequately identified the engine problem before sale. 4. Symptoms began October 13, 2026, during the initial drive home after purchase: black exhaust smoke during hard acceleration. On October 14, hesitation and an unusual whooshing/rushing-air noise occurred during highway acceleration. The check-engine light flashed intermittently, then went out when exiting the highway. On October 16, additional squeaking noises and an unusual odor developed while driving to work. Mileage was 12,599 at delivery on October 13 and 12,671 by October 17—only 72 miles driven since purchase. Symptoms began on delivery day and worsened within three days. Engine replacement was deemed necessary six days after delivery.

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.

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.

On August 25, 2026, while driving my 2026 Cadillac Escalade, the vehicle experienced a sudden and catastrophic engine failure. The engine lost power and the vehicle became inoperable while I was on the road. There was no meaningful advance warning that would have allowed me to safely anticipate the failure. The sudden loss of engine power created a serious safety concern because the vehicle could no longer be driven normally or moved under its own power. The vehicle ultimately had to be transported by a specialty tow service to an authorized Cadillac dealership. The Cadillac dealership inspected the vehicle and advised me that there was a major internal engine failure involving the bottom end of the engine, including the crankshaft/rod-bearing area, and that the engine requires replacement. The vehicle was purchased brand new on December 31, 2025 with approximately 15 miles and suffered this major engine failure less than eight months after purchase. The vehicle had approximately 12,000 miles at the time of the failure. The vehicle is currently at the authorized Cadillac dealership and is available for inspection. Cadillac/GM has been notified of the failure, and a case has been opened with the manufacturer. My primary safety concern is that a major engine failure occurred suddenly while the vehicle was being driven. A sudden loss of propulsion in traffic could create a significant risk of a collision, particularly at highway speeds or in circumstances where the driver needs engine power to safely maneuver the vehicle.
