2021 Cadillac Escalade Esv

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. GM’s 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. 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.

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).

My 2021 Cadillac Escalade ESV (VIN [XXX]) developed an engine failure after receiving the recall remedy for NHTSA recall 25V-274 (GM 6.2L V8 connecting rod/crankshaft defect). Symptoms: engine misfiring, dashboard warning lights illuminated, engine stalling/misfiring at idle, loss of power on acceleration, and a valve-like knocking noise coming from the engine. The loss of power and stalling while driving put my safety and the safety of others at risk. The vehicle is currently at the Vera Cruz Cadillac dealership, where it has been sitting for almost a month while awaiting the warranty process. The dealer has not confirmed the root cause. This engine failure occurred AFTER the 25V-274 recall remedy was completed on this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Body of what was just sent to GM- this should answer most/all questions: To the GM Executive Resolution Team, I am escalating a critical safety hazard and severe dealer misconduct involving my 2021 Cadillac Escalade (53,700 miles), which is fully covered under the GM Factory Powertrain Warranty and a GM Platinum Extended Warranty. This vehicle is experiencing its third catastrophic top-end valvetrain failure. The component history on this VIN is as follows: First Failure: Lifters replaced at a GM dealership in Miami, FL. The worn camshaft was left in place. Second Failure: Lifters replaced at AutoNation Cadillac West Palm Beach. The worn camshaft was left in place. Third Failure: The engine is actively failing again, knocking and ticking severely on warm restarts due to complete bleed-down. My last attempt to address this issue was to take the vehicle to Wallace Cadillac in Stuart, FL, and physically presented the Service Manager with glitter-filled oil and an oil filter containing metal debris, proving advanced mechanical erosion and engine self-destruction. Instead of initiating a warranty claim, the Service Manager/Senior Technician at Wallace Cadillac explicitly instructed me to continue driving the vehicle until it completely "blows up and have it towed in," claiming GM corporate would otherwise do nothing. As supporting evidence, he recited a recent claim refusal on an XT4’s engine where “I bore-scoped it and knew it was done, returned it to GM and they did not reimburse the warranty claim because we did not follow their tear down procedure”. Advising a customer to operate a 5,500-pound luxury SUV with heavily contaminated oil and a failing valvetrain until a catastrophic engine blowout occurs on a public highway is a profound safety violation and an extreme liability. A sudden engine seizure at highway speeds poses an immediate risk of a high-speed accident to my family.

I was driving down the interstate going 80 miles an hour and my engine completely shut off. I had to cross four lanes of traffic, on an interstate where the speed limit is 75 miles an hour, to get over on the shoulder while my car was able to accelerate. It was traumatizing and extremely dangerous and a miracle that a wreck was not caused. Engine would not start up after that.

On XXX I had been driving my vehicle with no issues. I had drove from [XXX] to [XXX]. My vehicle had no warnings or issues prior and my vehicle has been properly cared for and all oil and maintenance has been done through the Cadillac dealership in [XXX]. On my way to [XXX] I stopped at the local gas station and filled my gas tank fully up, when I started my vehicle there was a horrible sound and my car began to shake and all the electronics began coming up. I went to work less than 5 minutes down the road and the vehicle was horrible acting. I called my husband and began thinking maybe I had put bad gas in the vehicle because like i mentioned earlier there was nothing wrong with my vehicle prior to this. We contacted the dealership in [XXX] and they told us to bring the vehicle in, I had to drive my car back to [XXX] where i was petrified my vehicle was going to blow up or just die in the road. I made it to the dealership and explained what happened and that i thought it was bad gas, they let me know they would look at the vehicle and let us know. They contacted my husband later in the day and let him know the good news was that it was not bad gas, unfortunately my engine blew up. He said my engine has done what the recall engines have been doing, unfortunately my vehicle is not in the recall and that it would be $12,000.00 to fix it. When my husband called me, I had him three way the dealership and explained we have taken very good care of our vehicle with all maintenance and oil changes done there. He explained to me that it was nothing we could have done and i wanted to know why then the engine blew without warning and he continued to explain it was like the other vehicles in a recall. He kindly explained that there was nothing he could do but we could try and contact GM if we could get ahold of them and we could file a complaint reguarding our vehicle.
