Loss of motive power due to engine failure post recall remedy
On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V‑274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V‑274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GMâs recall remedy for Recall 25V‑274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V‑274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V‑274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall.

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.
6.2L Engine blew with less than 6,200 miles. Driving highway speed, started by hearing a slight tick and within 3 miles, the tick got louder, check engine light came on, then the pull over notice, pulled over and wouldn't start. Awaiting install of new motor for a Rear Main Bearing failure according to Service Manager.
Vehicle engine shutdown on routs [XXX] in [XXX] while traveling at 70mph. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
The contact owns a 2026 Cadillac Escalade. The contact stated that while driving 60 MPH, the vehicle failed to maintain automotive power. In addition, after depressing the brake pedal to stop the vehicle, the vehicle suddenly lost automotive power. The vehicle was taken to a local dealer where it was diagnosed; however, cause of the failure was not known. The manufacturer was made aware of the failure. The vehicle was taken back to the same local dealer, where it was diagnosed and determined that there were metal shavings inside the engine, engine oil pan, and the engine oil filter. The vehicle was also diagnosed with rod bearings #1 and #2 failures, and that the engine needed to be replaced. The failure mileage was approximately 7,000.
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.
Engine failior. Engine lost power on highway and lhad to limp to safety in traffic. With my children in the vehicle.
