Catastrophic engine and power train failure

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.

Catastrophic engine and power train failure

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.

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 NHTSA 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.

Engine failure and replaced. Received vehicle back and placed under 2k miles on the new engine and 3 times now it has shut off while in motion and required a restart.

On February 12, 2026, while driving my 2026 Cadillac Escalade from Corpus Christi to Portland, Texas, I encountered a severe safety issue. While driving on the bridge, the engine started making a loud knocking noise and then abruptly stopped working, causing the vehicle to turn off in the middle of traffic. I have only had my vehicle for a total of 55 days, and the mileage on my vehicle is 2,455 miles. This incident highlights a critical motor failure that poses a significant safety risk.

ON FEBRUARY 16, 2026, AROUND 4:30 P.M. WE WERE DRIVING OUR NEW CADILLAC ESCALADE SPORT V-SERIES WITH ONLY 900 MILES ON THE ODOMETER AT AROUND 50 MILES PER HOUR ON HIGHWAY T IN FRANKLIN COUNTY TO OUR HOME FROM THE DOG GROOMER WITH OUR 2 LARGE BREED NEWFOUNDLAND DOGS WHO WEIGH 130 POUNDS EACH NAMED [XXX] AND SQUIGGY WHO WERE LAYING DOWN IN THE REAR CARGO AREA WITH THE 3RD ROW SEAT FOLDED DOWN WHEN I NOTICED THE VEHICLE WAS SLOWING DOWN EVEN THOUGH I HAD MY RIGHT FOOT ON THE ACCELERATOR AND THAT'S WHEN I NOTICED THAT THE TRANSMISSION HAD UNEXPECTEDLY AND WITHOUT WARNING SHIFTED FROM DRIVE TO NEUTRAL WITHOUT ANY ALERTS OR WARNING MESSAGES. THEN, SUDDENLY AGAIN WITHOUT ANY ALERTS OR WARNING THE BRAKES LOCKED UP ON THE HIGHWAY THROWING US FORWARD INCLUDING [XXX] AND [XXX] INTO THE BACK SIDES OF OUR DRIVER AND PASSENGER SIDE SEATBACKS. IF ANY OTHER MOTORISTS HAD BEEN FOLLOWING US CLOSELY THEY WOULD HAVE RISK COLLIDING WITH THE REAR BUMPER AREAS OF OUR VEHICLE. I IMMEDIATELY SHUT THE VEHICLE OFF CHECKED TO MAKE SURE NO OTHER MOTORISTS WERE APPROACHING US WHILE STOPPED ON THE HIGHWAY AND RESTARTED THE VEHICLE AND DROVE LESS THAN 1 MILE TO OUR HOME. WE UNLOADED [XXX] AND SQUIGGY WHO WERE LUCKILY NOT INJURED AFTER BEING THOWN FORWARD WHEN THE BRAKES UNEXPECTLY LOCKED UP AND CALLED ELCO CADILLAC SERVICE DEPARTMENT AND NOTIFIED THEM OF THE SAFETY CONCERNS WE HAD ABOUT THE ENGINE SHIFTING INTO NEUTRAL AND THE SUDDEN UNEXPECTED HARD BRAKING EVENT WE JUST EXPERIENCED AND THAT WE'D BE DRIVING TO THE DEALERSHIP ABOUT 10 MILES FROM OUR HOME TO DROP OFF THE ESCALADE TO DETRERMINE IF THERE WERE ANY CODES IN THE COMPUTER IDENTIFYING THE ISSUES WE ENCOUNTERED. WHEN WE ARRIVED ABOUT 5:45 THE TRANSMISSION WAS NOT SHIFTING PROPERLY AND THE ENGINE WAS MAKING A RATTLING NOISE. AS WE PULLED UP TO THE AUTOMATIC GARAGE DOOR SERVICE ENTRY THE TRANSMISSION AGAIN SHIFTED INTO NEUTRAL AND THE ENGINE SHUT OFF COMPLETELY AS WE ROLLED INSIDE SERVICE ENTRANCE.

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.
