2021 Cadillac Escalade Esv

The Office of Defects Investigation (ODI) has received 36 Vehicle Owner Questionnaires (VOQs) alleging engine failure in vehicles subject to Recall 25V274. In each VOQ, the engine had the recall remedy completed prior to the reported failure incident. Recall 25V-274 addresses vehicles equipped with a L87 6.2L V8 gas engine that experienced engine damage or failure. Recall 25V-274’s remedy includes an engine inspection.  Based on the results of the inspection the vehicle will receive an oil change to a higher viscosity oil or an engine replacement.  The complaints received allege failures of both remedies. ODI is opening this Recall Query (RQ) to assess the adequacy of the remedy for Recall 25V-274. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001).  GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274.  This presents a potential safety risk that warrants further investigation.  ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024.  GM cited the root cause as a supplier manufacturing and quality issues. GM’s  recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).

On April 9, 2021, the Office of Defects Investigations (ODI) opened PE21-010 to investigate instances of air bag malfunction indicator light (MIL) illumination and potential for frontal air bag non-deployment in several vehicles manufactured by General Motors (GM). The vehicles included model year (MY) 2020 through 2021 CT4 and CT5 passenger cars, Sierra and Silverado trucks (1500/2500/3500 models), XT4 and MY 2021 Escalade, Suburban, Tahoe, Yukon SUVs.Technical Service Bulletin (TSB) 21-NA-005, issued in March 2021, addresses air bag MIL illumination with diagnostic trouble codes (DTCs) B0001-1B or B0012-0D. It cites rust particles in the connection terminal interface of the driver air bag inflator housing as the cause of the air bag MIL illumination. Illumination of the air bag MIL under these circumstances may result in a non-deployment of the frontal driver air bag during a frontal collision and increased risk of injury to the driver.GM stated a correlation exists between production delays due to the pandemic shutdown and premature corrosion initiation on the surface of the air bag inflator housing, which, in some cases, caused rust development during a seven (7) month period of vehicle production. In the rare instance when a rust particle dislodges from the driver air bag inflator housing and enters the air bag connector prior to assembly, an intermittent resistance spike at the air bag connector may result. The condition generates excessive resistance in the air bag electrical system when the steering wheel horn cover is manipulated or the steering wheel is turned. This excessive resistance is momentary. A crash commanding air bag deployment would need to occur exactly when the momentary excessive resistance occurs. Thus, there is a very low likelihood the hazard will present a risk during a crash of sufficient severity to warrant a commanded deployment. This failure mechanism occurs early in life and results in an air bag MIL illumination that corresponds to a DTC warning the driver that the vehicle requires service. The vehicle's air bag remains functional while the MIL is illuminated, and the DTC is present.Once the connection of the driver air bag module to the clockspring is made at the plant, or at the dealership for service, there is no longer an opportunity for rust migration into the connection point. The connector is sealed and has gold terminals, eliminating the expectation of fretting corrosion. All subject vehicles passed standard corrosion validation testing for extensive corrosion with no issue of air bag non-deployment.There is a low rate of occurrence: 1.41 incidents per thousand vehicles (IPTV) for all related occurrences, and 0.04 IPTV for occurrences with a mention of visible rust and/or corrosion on the air bag inflator housing. The average occurrence mileage for the subject vehicles is approximately 2,100. Every occurrence related to the alleged defect experienced an air bag MIL illumination and there are no verified allegations of air bag non-deployment within all data sources.To date, there have been no reported fires, crashes, injuries, or fatalities related to this issue. In view of the low rate, and the nature of early-life failure, the high detectability of failures, and low potential hazard to drivers, this Preliminary Evaluation (PE) is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.Review the ODI reports cited above at nhtsa.gov under the following identification numbers: 11537927, 11528888, 11525020, 11521401, 11506057, 11493107, 11486767, 11441525, 11433146, 11425658, 11423440, 11385267, 11376429, 11373466, 11366995.

2021 Cadillac Escalade ESV equipped with L87 6.2L V8, subject to NHTSA Recall 25V-274 / GM N252494000. The recall inspection was completed and the vehicle passed, so GM performed the 0W-40 higher-viscosity-oil remedy rather than engine replacement. The vehicle has a history of unexplained oil loss with no obvious external leak, including a prior low-oil warning. At a recent oil change after approximately 5,000 miles, no oil registered on the dipstick before service. The engine was then filled to the full mark. Using the same repeatable checking method, the level was approximately 3/4 at 227 miles and approximately 1/2 at 1,300 miles. I am concerned that a progressive internal engine condition may not have been detected by the recall inspection and that the oil-only remedy may be inadequate. NHTSA currently has Recall Query RQ26001 open regarding engine failures after Recall 25V-274 remedies. I am also concerned because GM Special Coverage N252494003 excludes an engine presenting with low/no oil as neglect even if unresolved mechanical oil consumption caused the low level. I am requesting this complaint be associated with Recall 25V-274 and RQ26001. Please advise. I just bought the car less than a year ago and can’t a new engine.

My 2021 Cadillac Escalade ESV with the 6.2L L87 engine received the remedy for Safety Recall 25V-274 (GM recall number N252494001) on July 30, 2025. The dealer inspected the engine, passed it, and performed the higher viscosity oil remedy. The engine was not repaired or replaced. On [DATE], while driving, the vehicle hesitated and lost power under acceleration. Engine noise then increased progressively until I pulled over on the side of the road. The engine stopped running and would not restart. The dash displayed a message to press the start button again. The check engine light illuminated at the time of failure. There were no warning lights prior to that day. My family, including my children, were in the vehicle when it lost power. We were stranded on the roadside until the vehicle could be towed. The battery and electrical system are functioning normally, but the engine would not start. The vehicle was towed to a Cadillac dealership. At the dealership, a start attempt produced a loud knocking noise from the engine along with a fuel/oil odor. I believe the connecting rod bearings have failed. These symptoms — hesitation, loss of power, and knocking noise — are the exact pre-failure indicators GM identified in Recall 25V-274. This was a loss of motive power while driving on a public roadway, creating a serious crash risk for my family and surrounding traffic. The recall remedy performed on this vehicle was inadequate. GM inspected this engine, passed it, and it failed approximately one year later in exactly the manner the recall was intended to prevent. Date of incident: 08/08/2026 Mileage at failure: 66,000 Recall remedy completed: July 30, 2025 Vehicle was towed. No crash, fire, or injury occurred.

I purchased a 2021 Cadillac Escalade ESV and shortly thereafter experienced an engine malfunction. The vehicle developed a misfire, rough idle, loss of power, and produced significant blue/white exhaust smoke. The check engine light illuminated and the vehicle began running abnormally. An independent repair facility inspected the vehicle and reported oil-related issues affecting a cylinder and spark plug. The repair facility also observed excessive exhaust smoke during diagnosis. The condition raises concerns about potential engine failure while driving, which could result in loss of power and create a safety hazard in traffic. The vehicle is currently undergoing diagnostic testing, including a leak-down test, to determine the cause of the failure. The problem has been confirmed by a repair facility and occurred shortly after purchase.

The contact owns a 2021 Cadillac Escalade ESV. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. Several dealers were previously contacted for recall inspection appointments, and the contact was informed that the manufacturer had denied the request to perform the service. A dealer was recently contacted and agreed to schedule the recall repair appointment. The dealer informed the contact that the vehicle would remain with the dealer in the event that the vehicle failed the inspection, and the vehicle would be repaired in 3-4 months because the part was on backorder. The contact was informed that vehicle rental assistance might not be provided. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

Incident

Apr 6, 2026

I purchased a used 2021 Cadillac Escalade in May 2025 with approximately 48,000 miles. While driving on Highway 14 near Acton CA at speeds exceeding 60 mph, the vehicle experienced a catastrophic engine failure (March 28th - 2026). The engine suddenly lost all power and shut off completely while in motion. Only electrical systems remained operational. At the time of the incident, I had my three children in the vehicle. This created a dangerous situation, as I was forced to maneuver across traffic and safely pull over without engine power. The vehicle could not be restarted and had to be towed to the dealership. The dealership replaced the engine with a refurbished unit April 14th - 2026. I was not informed in advance that the replacement engine would be refurbished rather than new. Immediately following the engine replacement, the vehicle began experiencing additional issues, including electrical malfunctions and air suspension problems, which required further repairs. After retrieving the vehicle, it is still not operating as expected. The vehicle is noticeably slow, sluggish, and noisy, raising concerns about reliability and the potential for another failure. Given the sudden loss of engine power at highway speed and the continued performance issues after repair, I have serious concerns about the safety of this vehicle.
