Cadillac Escalade check engine light comes on

Filed Nov 4, 2026 · Acceleration, Electrical · UT

We purchased this '27 Escalade on Thursday 22nd of October. We had it for 6 days or about 200 miles when we received a check engine light that turned on along with a message "Reduced acceleration drive with care". We took it to the dealership in which they've had it for a week now with no answers. They tried to replace one module but that didn't work as another module then failed. This is extremely disappointing as we just paid for a very expensive vehicle, and still have to pay the insurance, while not being able to drive it. GM needs to make this right, but the federal safety agency should know of these issues that persist.

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.

The contact owns a 2021 Cadillac Escalade. The contact stated that while driving at 35 MPH, the vehicle completely stalled. The check engine warning light was flashing, and the Stability, Parking, and Collision warning lights were illuminated alongside several other unknown alerts. The vehicle was towed to a dealer, where two failed lifters were initially replaced. However, due to an abnormal sound, the vehicle was returned to the dealer, where the engine was replaced with a remanufactured engine. The manufacturer was notified of the failure by phone. The failure mileage was approximately 67,300.

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 received a recall notice for catastrophic engine failure on my 2023 Cadillac Escalade sport platinum. I took it into Cable Dahmer Caddy Sales. They ran a test and added a thicker oil. My check engine light turns on roughly every 40 to 60 days and I take it to get service and it usually comes back with no error but why is the check engine light keep popping on and flashing. I’ve been reading about this catastrophic engine failure on the 6.2 V8 engine that’s in my vehicle and adding the thicker zero40 oil and running premium which nothing lower than 91 goes in my vehicle is just buying me time until I’m outside of my factory warranty. And on this website it says that no recalls have been repaired but is adding thick oil repair or as it’s being stated just a fix and draws out the eventual catastrophic engine failure. I’m just assuming that that’s going to happen as soon as my car is out of Warranty is there anyway we can get this tracked correctly on the website that shows that my vehicle does not have that particular engine that ceases up and fails and could I get a better explanation why my check engine light continues to come on and the dealership says there’s no issue they couldn’t get it to misfire again thanks

This is a POST-REMEDY FAILURE. Please associate with EA26005. The replacement engine installed in July 2025 under recall 25V‑274 has now failed at approximately 16,000 miles. In August 2026 at 70,606 miles the check engine light illuminated and the vehicle ran roughly and felt like it would stall. The dealer performed GM campaign N252510321 (ECM software update), found nothing further, charged $325 in diagnostics and returned the vehicle after a factory reset. The light returned within a week with additional faults. On the second visit (RO 198718, 71,355 miles) the dealer found codes P0300 and P0304, swapped coil, wire and plug to known-good cylinders with the misfire following cylinder 4, and measured 0 PSI compression. Diagnosis: lifter failure. Right-bank lifters, pushrods and oil valve solenoids were replaced. 15 days out of service. Days after pickup the vehicle developed a whining noise in reverse, then illuminated traction control, collision system and check engine warnings simultaneously during a short drive. The vehicle is currently not safe to drive. The dealer instructed me to drive it 35 miles to the dealership and declined both a tow and a loaner. Stalling in traffic and simultaneous loss of traction control and collision avoidance present a crash risk.

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.
