Cadillac Escalade Engine Failure: The L87 V8 Recall and California Lemon Law

An engine that can lose power while you are driving is one of the most serious defects a vehicle can have, and in 2025 General Motors acknowledged exactly that risk in its 6.2L V8. If you own a Cadillac Escalade built in the affected window, it is worth understanding what the recall covers, what the repair actually does, and where California's Lemon Law fits in. This is general information, not advice about your specific vehicle.

What recall 25V274 covers

In 2025, GM opened safety recall 25V274 for vehicles equipped with the 6.2L V8 gas engine known internally by the RPO code L87. The campaign covers 2021-2024 model year vehicles across the GM lineup, including the Cadillac Escalade and Escalade ESV, along with the Chevrolet Silverado 1500, Tahoe and Suburban and the GMC Sierra 1500, Yukon and Yukon XL. For the Escalade specifically, the affected production window runs from March 2021 through May 2024.

According to GM's filing, the connecting rod and crankshaft components in these engines may contain manufacturing defects, traced to supplier quality issues such as sediment left on connecting rods and out-of-specification crankshaft dimensions and surface finish. The concern grew out of NHTSA investigation PE25001 into loss-of-propulsion complaints.

Why an engine defect is a serious safety issue

The reason this recall matters is not just the cost of repair. GM's own filing states that if the engine fails during operation, the vehicle loses propulsion, which increases the risk of a crash. A full-size SUV that suddenly loses power in traffic is a safety hazard for the driver, the passengers and everyone nearby. Defects that affect the safe operation of the vehicle are treated very differently from cosmetic problems under California law.

The remedy, and its limits

The recall provides for two different outcomes depending on what a dealer inspection finds:

• If the engine passes inspection, the dealer installs a higher-viscosity oil, a new oil fill cap and a new oil filter, and adds an insert to the owner's manual.
• If the engine fails inspection, the dealer replaces the engine as necessary.

An oil change is a reasonable first step for an engine that has not yet been damaged, but it does not undo damage that has already started, and it does not guarantee the problem will not return. If your Escalade has already shown symptoms such as knocking, metallic noise, warning lights, power loss or a stall, or if it needs a full engine replacement, that is a substantial repair to the most important system in the vehicle. When a major defect keeps requiring attention, the question shifts from whether it can be patched to whether the manufacturer has had a fair chance to fix it.

How California's Lemon Law treats an engine that fails

Under California's Song-Beverly Consumer Warranty Act, a vehicle may qualify as a lemon if a substantial, warranty-covered defect cannot be repaired after a reasonable number of attempts, or if the vehicle has been out of service for 30 or more cumulative days for warranty repairs. An engine that loses propulsion is close to the center of what the law was written to address, because it goes directly to safety and to the core function of the vehicle.

A recall is not automatically a lemon, and a defect does not have to be recalled to support a claim. But a recall like 25V274 can help in two ways: it is the manufacturer acknowledging a defect exists, and the days your vehicle spends waiting for inspection, parts or an engine replacement count toward the out-of-service total that owners routinely undercount.

Cadillac and the AB 1755 filing deadline

Cadillac's parent, General Motors, has opted into California's AB 1755 procedures, which can mean a shorter filing window than many owners expect: generally within one year of your warranty's expiration, and no later than six years from the vehicle's original delivery date. If your Escalade's warranty has lapsed or is close to it, the deadline is the first thing to check, not the last.

What to do if your Escalade is affected

• Enter your VIN at NHTSA.gov to confirm whether 25V274 or any other campaign is open on your exact vehicle.
• Keep every repair order, including visits where you were told the behavior was normal.
• Write down every day the vehicle is out of service waiting for inspection, parts or an engine.
• Save your purchase or lease agreement and any recall letters from Cadillac or GM.
• Talk to a California lemon law attorney before agreeing to another repair attempt if the problem keeps coming back.
