2021 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.

ODI will close this RQ and continue to investigate complaints of post-remedy engine failure for Recall 25V-274 as part of an Engineering Analysis (EA26005).

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).

Incident

Jun 5, 2026

I own a 2021 Cadillac Escalade Premium Luxury with approximately 47,000 miles. On Oct 11, 2026, after stopping for gas, I noticed shortly after driving away that my entire digital instrument cluster was black. I had no speedometer, fuel gauge, mileage display, or dashboard warning indicators, although the center infotainment screen worked. I do not know whether the display went black when I restarted the vehicle or while driving; I discovered it while driving. The display worked again after I shut off and restarted the vehicle after a few hours. I scheduled an appointment with Cadillac of Calabasas on Oct 11, but the earliest available appointment was Oct 21, 10 days later. Around Oct 13, my vehicle also displayed a “Service Driver Assist System” warning, which returned on Oct 22. When I brought my vehicle to Cadillac of Calabasas on Oct 20 (trying to drop off a day early), the advisor checked for open recalls and said there were none. He incorrectly stated my warranty expired in July 2025; Cadillac corporate later confirmed my CPO warranty expired July 11, 2026. I was told the dealership was backed up at least another week and everything would be paid out of pocket. No diagnosis or repair was completed as I could not leave my car for a week. Despite multiple contacts with Cadillac Customer Assistance (case 116067222), these problems remain unresolved. I have photographs and video documenting the instrument cluster blackout and driver-assistance warning and can provide them upon request. I am concerned about losing critical driving information and the reliability of my vehicle’s driver-assistance systems. I am requesting NHTSA investigate these potential safety defects.

There is internal engine failure. Yes it is available for inspection. My safety as well as others were at risk when the engine started to fail, without warning, causing my car to jolt and briefly lose control of steering. If complete engine failure happened while driving, I would not have control over my car. My life and other's lives would severely be at risk. Car has been inspected and confirmed engine failure. Car is unable to be driven as we do not want to put anyone else at risk or make the problem worse. Car will be towed on Monday. There was absolutely no warning of this occurring. The symptoms first appeared while driving and the incident happened shortly after. There was a loud noise followed by my car being jerked traffic. I immediately pulled over until I could get my car safely home. When inspected the car was ticking with brief knocking noises. The ticking continued while the knocking noise became more abrupt and frequent.

After soft-close, left-side passenger door won't open. Not form the outside, not from the inside. Happened before about a year ago. logged into dealer system but the were unable to identify (and correct) the issue. This presents a big hazard in case of an accident, roll-over etc - unable to exit the vehicle swiftly.

While driving in a heavy rainstorm on October 15, 2026, the vehicle hydroplaned and every brake warning light came on at once, and the dashboard displayed a message that the brake system had failed and the brakes did not work. I believed I had no brakes while crossing a river bridge and thought I was going to die. The brakes actually worked and I got home, but a vehicle should never tell a driver its brakes have failed when they have not, especially in an emergency. All brake warning lights stayed on after I parked. The vehicle has not yet been inspected for this failure.

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.

With just over four years of service, backup camera driver assistance system began to fail, with it working intermittently and eventually going completely dark. This being a safety feature, the warranty ought to cover it but manufacturer argues not. We understand many other Cadillacs have the same problem.
