What is confirmed

The recall is VIN-specific.

GM submitted Safety Recall 25V-274 on April 24, 2025 for certain 2021–2024 full-size trucks and SUVs with the 6.2L V8 gas engine, RPO L87. A listed model year alone does not establish that a specific vehicle is included. [1]

Best first step: check the exact VIN at GM or NHTSA, then save the result with the date. It is the only reliable way to confirm an open campaign.

The recall report covers certain vehicles, not all vehicles in these model-year ranges. Verify by VIN. [1]

Why the recall was issued

GM identified manufacturing-related engine-component concerns.

GM’s Part 573 report describes potential connecting-rod and crankshaft manufacturing defects, including rod-bearing damage related to sediment and crankshaft dimensions or surface finish outside specification. The stated safety concern is engine damage or failure that can cause loss of propulsion while driving. [1]

Possible warning signs

Reported signs include knocking or banging noise, a check-engine light, hesitation, unusually high RPM, abnormal shifting, reduced propulsion, or a no-start condition.

Dealer inspection

The campaign instructs dealers to inspect the engine. The repair order should identify the inspection result and any campaign action performed.

Records matter

Keep repair orders, invoices, symptom notes, mileage, and dates. The dealer bulletin addresses requests for reimbursement of certain prior related repairs, subject to GM policies.

Symptoms are informational only. Use professional service and the VIN lookup to determine current recall status. [1] [2]

Recall remedy overview

What the campaign bulletin says dealers do

The dealer bulletin directs an engine inspection. If the inspection does not pass, the bulletin moves the vehicle into an engine-repair or replacement procedure. If it passes, the specified remedy includes a 0W-40 oil change, new oil filter, new oil-fill cap, and owner-manual insert. [2]

A P0016 code or audible rod knock is identified in the bulletin as a condition that directs the technician into the engine-replacement procedure. The dealer determines results for the specific vehicle. [2]

2026 investigation update

EA26005 is not a new recall.

NHTSA opened Engineering Analysis EA26005 on August 20, 2026 after reviewing reports of alleged engine failures following the recall remedy and reports involving L87 engines built after the original campaign range. It covers 2021–2026 GM models with L87 engines in NHTSA’s analysis population. [3]

An engineering analysis does not automatically expand recall coverage. Continue checking your VIN for official campaign updates. [3]

Documented timeline

The recall and later reviews are different events.

The original recall, an engineering analysis outside the recall range, a recall-query review, and EA26005 each have a different purpose. Keep that distinction in mind when reading a headline or speaking with a service department.

  1. January 16, 2025

    PE25001 opened

    NHTSA opened its preliminary evaluation into loss of motive power from L87 engine failure. [9]

  2. April 24, 2025

    Recall 25V-274 announced

    GM submitted Safety Recall 25V-274 / N252494000 for certain 2021–2024 L87-equipped full-size trucks and SUVs. [1]

  3. October 23, 2025

    EA25007 opened

    NHTSA opened an engineering analysis after receiving 1,157 L87 bearing-failure reports, including 173 reports outside Recall 25V-274’s scope. [7]

  4. January 16, 2026

    RQ26001 opened

    NHTSA opened a recall query after 36 owner reports alleged a failure after the recall remedy had been completed. [8]

  5. August 20, 2026

    EA26005 opened

    NHTSA opened a separate analysis of reported post-remedy failures and later-production L87 engines. It is an investigation, not a new recall. [3]

After a remedy or outside the recall

Start with the current VIN status, then save your records.

An oil remedy or engine replacement recorded in the past is meaningful history, but it does not answer whether a present concern has an open campaign, special coverage, or any other available path. Ask for the VIN result and a documented repair order. [8]

Open recall by VIN

Ask the dealer to confirm the campaign status and provide the documented inspection and remedy result on the repair order. [2]

Recall already completed

If a later concern occurs, keep the prior remedy date, repair order, and symptom history. RQ26001 and EA26005 concern reported failures after recall remedies; they do not automatically determine coverage for an individual vehicle. [8]

No open recall by VIN

Do not assume recall eligibility from model year or engine size. Ask the dealer what campaigns or coverage apply today and monitor official NHTSA and GM updates. [5]

EA26005: what NHTSA is reviewing

Reported failures after a remedy and in later-production engines.

NHTSA’s August 2026 Engineering Analysis records owner reports and GM-reported complaints. These figures describe the investigation record; they do not establish a new recall or determine coverage for a particular VIN. [3]

499

owner complaints alleging a failure after the recall remedy [3]

473

Separate special coverage

N252494003 is also VIN-specific.

GM released Special Coverage N252494003 in a phased population for certain vehicles that had completed the related recall actions. Its published coverage period is 10 years or 150,000 miles, whichever occurs first, from the original in-service date. [6]

What owners should know

GM’s May 2025 bulletin describes a phased special-coverage population for certain VINs that had completed and closed the related safety-recall actions. It directs the dealer to confirm a VIN in GM’s Investigate Vehicle History before beginning work. [6]

The bulletin lists exclusions and VIN-specific conditions. A listed model or symptom does not establish special-coverage eligibility. [6]

Common questions

Separate the recall from the investigation.

Does every 2021–2024 GM truck or SUV have this recall?+

No. The recall applies to certain listed vehicles equipped with the 6.2L V8 gas engine (RPO L87) within GM’s identified manufacturing window. Confirm the vehicle’s status by VIN through GM or NHTSA. [1]

What does the 25V-274 remedy involve?+

GM’s bulletin directs dealers to inspect the engine. A failed inspection leads to engine repair or replacement. A passing vehicle receives the specified 0W-40 oil, oil filter, oil-fill cap, and owner-manual insert described in the campaign materials. [2]

Is EA26005 a new recall?+

No. EA26005 is an NHTSA Engineering Analysis opened in August 2026. It is an investigation into reported L87 engine failures after the 25V-274 remedy and in engines beyond the original production range; it is not a new recall or an automatic expansion of recall coverage. [3]
