2023 Cadillac Escalade

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).

The motor is making lots of weird noises and idling weird. This motor was replaced due to the L87 motor recall and sounds like it’s going to fail again.

The contact owns a 2023 Cadillac Escalade. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the repair failed to prevent a failure from occurring. The contact stated that while driving at higher speeds, the vehicle suddenly lost automotive power. The vehicle was towed to the same local dealer where the engine was replaced twice, and the engine failure was confirmed. The manufacturer was made aware of the failure by telephone, and a case was filed. The failure mileage was approximately 60,000.

I am reporting a catastrophic engine failure on my 2023 Cadillac Escalade with the 6.2L L87 V8 engine (currently at 106,000 miles). The engine suffered sudden engine failure while driving / stalling, creating an immediate traffic hazard. The vehicle was towed to an authorized Cadillac dealership in Louisiana, where it has remained completely unrepaired for 60 consecutive days. The dealership claims they cannot repair the safety defect because they are "short-staffed." This vehicle’s failure directly matches the systemic manufacturing defects currently under investigation by the Office of Defects Investigation in Engineering Analysis EA26005. The manufacturer's inability to provide a timely repair through its dealer network leaves a known safety hazard unresolved.

Incident

Oct 15, 2026

Around May 2025; we noticed a ticking/knocking noise coming from our engine. We popped the hood, confirmed the noise was coming from somewhere in the engine. Shut the vehicle off, noticed that the drive belt was significantly damaged/frayed. Brought it to the dealership - they we were informed that our engine had failed related to the GM 2025 recall. Engine was replaced at 68,500 miles with new engine. October 2026, around approximately 103,000 miles, we heard the same ticking/knocking noise coming from the engine. Again, popped the hood & found the drive belt to once again be destroyed, this time even worse from our perspective. Cracked in several places, frayed edges along several sections. Had the vehicle towed back to the same dealership the following day (Monday). Service advisor let us know the next day that the engine had "internal failure." Per the technician, "crankshaft bearing failure - premature wear, oil pressure collapse, and destruction of the main and rod bearings."

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
