That makes a strong case for buying used. However, given this engine’s history with safety campaigns, a “recall completed” status may not be enough to prevent headaches down the road. The used market is cooperating, at least on price. Recent Manheim index data from [Cox Automotive]() shows that wholesale prices for pre-owned pickups and SUVs are down from a year ago. But there’s a catch: in August, Tim Esterdahl [reported]() that the National Highway Traffic Safety Administration (NHTSA) is investigating reports of GM engines failing after the recall repair was already done. A cheap Silverado or Tahoe isn’t much of a bargain if its engine fails later. If you’re shopping for a 2021–2024 GM truck or SUV with the L87, ask for the service records, even if the recall lookup comes back clean. A completed recall could mean the dealer switched to a different oil grade, or it could mean the engine was replaced. The lookup won’t tell you which. ## **Quick Answer: What to Check Before You Buy** - Check the vehicle’s build date and the presence of the L87 engine. - Using the vehicle identification number (VIN), have a GM dealer verify what recall work was completed. - Review the recall repair order for service date, mileage, and inspection results. - Establish whether the engine passed inspection, was replaced, or had a qualifying earlier replacement verified. - Compare the recall paperwork with the oil-fill cap and owner’s manual insert if the engine kept its original block. - Negotiate using comparable trucks and unresolved investigations as a bargaining chip. - Have a GM-experienced mechanic perform a comprehensive pre-purchase inspection. ## **Why a Clean VIN Check Doesn’t Prove the Engine Was Fixed** Using the [NHTSA recall lookup tool]() is always a good idea before buying any vehicle. However, the results only show open recalls. You can’t use this resource to identify completed recall repairs or learn what remedy the dealer performed. These results don’t distinguish between a truck with a completed safety campaign and one that wasn’t part of a recall in the first place. For the L87 engine, the latest GM recall filing lists 597,571 affected vehicles. The problem stems from manufacturing-related debris that can damage crankshafts and internal bearings, leading to engine failure. GM estimates it affects 3% of the recalled population. Before you go any further in the shopping process, it’s a good idea to obtain a [vehicle history report](). This step can help you weed out any pickups or SUVs with a branded title, a reported accident, inconsistent mileage, or unusual ownership activity. ## **Step 1: Check the Build Date Against the Recall Window** The process starts by identifying the GM vehicles affected by [Recall 25V274](), which involves the following vehicles equipped with the L87 engine and built between March 1, 2021, and May 31, 2024: - Cadillac Escalade - Cadillac Escalade ESV - Chevrolet Silverado 1500 - Chevrolet Suburban - Chevrolet Tahoe - GMC Sierra 1500 - GMC Yukon - GMC Yukon XL Notice those production dates. Some vehicles from the 2021 and 2024 model years fall outside that production window and may not be included in the recall. Check the certification label on the driver’s door jamb, and take a photo that captures the VIN and manufacture date. Compare the VIN on the label with any paperwork you review. You can also contact a Chevrolet, GMC, or Cadillac dealer to confirm whether the VIN was included in the safety campaign and if repairs were completed. The engine concerns also extend to vehicles built after the original recall window. [NHTSA opened investigation EA26005]() into reported L87 engine failures involving 997,743 GM pickups and SUVs from the 2021–2026 model years. The agency has almost 200 reports of these incidents. It’s too early to tell whether the recall could be expanded to newer models, but prospective buyers should be aware of the situation. ## **Step 2: Ask for the Recall Repair Order** The best proof of how the recall was handled is the repair order itself. If the seller doesn’t have the documentation, ask them to get a copy from the servicing dealer. The seller can remove any personal information before sharing the records. To ensure you have the correct paperwork, look for the N252494000 designation, GM’s coding for the 25V274 recall campaign. The repair order should detail inspection results and the work performed. The repairs may have included a knock-sensor or PicoScope test rather than basic technician observations. If so, ask for an explanation of the results. If the recall work was closed as an inspection-only procedure, ask why it was closed that way instead of replacing the engine. ## **Step 3: Find Out Which Fix the Truck Got** Your investigation should include asking one simple question: Did the dealer change the oil or replace the engine? Under [GM’s recall instructions](), the dealer replaced an engine that wouldn’t run, had a specific trouble code (P0016), or failed the dealer’s test. For an engine with a knocking noise, GM’s instructions call for a diagnostic test to determine whether it needs to be replaced. If the engine passes, the dealer changes the oil to a 0W-40 formulation, installs a new oil filter and oil-fill cap, and adds the new oil maintenance instructions to the owner’s manual. In these instances, the vehicle keeps its original engine; its internal parts aren’t replaced. If the engine was swapped, find out at what mileage and compare it with the current odometer reading. If the work was recent, there’s not much history about how the new engine is holding up. If the new engine was installed some time ago, keep in mind that you’re still dealing with a vehicle with the same transmission and other systems that can still impact reliability. You’ll also want to confirm the engine’s oil requirements and that the maintenance instructions have been updated in the owner’s manual. Problems have been reported after both fixes. NHTSA received 499 complaints alleging engine failure after recall work: 473 after the oil change and 26 after an engine replacement. GM separately reported 6,953 complaints, which may involve some overlap with the NHTSA reports. ## **Step 4: Look in the Glovebox and Under the Hood** If the recall paperwork indicates that the original engine passed and received the oil-change remedy, look for an oil-fill cap marked 0W-40 and the owner’s manual insert. The recall work may have been completed even if these items are missing, but you’ll need to ask more questions. A new oil cap doesn’t prove that the recall was completed either. The cap could have been changed later. Regardless, a mismatch between the documentation and the physical evidence requires an explanation from the seller. This is also a good time to look at post-recall oil-change receipts and verify that the correct oil grade was used. If a receipt lists a different oil grade, ask a GM dealer whether it was appropriate for the engine in that truck. Have the dealer explain any mismatch before you buy. ## **Step 5: Use the Open Investigation to Lower Your Offer** NHTSA is investigating reports of engine failures after recall repairs and in vehicles built after the original recall window. These unresolved concerns give buyers a reason to negotiate, but there’s no standard discount to apply. Start with an apples-to-apples comparison on models with the same year, trim, powertrain, mileage, and condition. You may need to dig deeper to determine how the L87 recall was handled for each vehicle. Also, you can bring up softening wholesale valuations from the Cox Automotive data. Because used GM vehicles with the affected 6.2-liter V8 are abundant, don’t limit your negotiating efforts to one seller. Some dealers may be more attuned to a changing marketplace and the buyer reluctance that comes from recall campaigns. You should also know that many of these affected models benefit from [GM’s special-coverage bulletin](), which covers eligible vehicles with protection for 10 years or 150,000 miles, whichever comes first, from the original in-service date, regardless of ownership. It isn’t a general warranty extension; it covers only the engine condition connected with the recall. A GM dealer can confirm eligibility, so get it in writing. Before making an offer, confirm the vehicle’s remaining engine coverage and deduct the cost of any needed repairs identified during the inspection. Then compare the total price with similar trucks. Any additional discount for the unresolved engine concerns is negotiable, but weigh the savings against potential engine repair costs that GM won’t cover, repair delays, and time without the vehicle. ## **Step 6: Know When to Bring In a Mechanic** While it’s always a good idea to get a [pre-purchase inspection]() before any used car purchase, it’s especially important for an L87-equipped GM vehicle. Because of the expense involved (typically $200–$300 for a comprehensive exam), save this for the final step before signing any paperwork. Ideally, you want someone experienced with the 6.2-liter engine and GM products, and independent of the seller. The inspection should include a cold start, a warm idle check, and an extended road test (preferably under load). The technician should watch for unusual engine knocking, check fluid levels, and scan for stored and pending diagnostic trouble codes, including P0016. A stored or pending P0016 code, or another code suggesting an engine problem, should be checked before you buy. Because of the time involved, an oil analysis may not always be practical, but it can provide additional insights into engine wear and contamination for a modest investment (under $50). According to [Blackstone Laboratories](), an oil analysis can’t predict how long an engine will last. However, knowing the mileage since the last oil change helps put the wear and contamination readings in context. Remember to inspect the rest of the vehicle, too. Check the transmission, along with the other major systems. If the seller refuses an inspection or the technician identifies engine troubles, it’s time to move on to another vehicle. ## **Green Flags vs. Red Flags at a Glance** | Check | Green Flag | Red Flag or Reason to Pause | | --- | --- | --- | | Repair order | VIN, mileage, and completed work are documented | Only a verbal assurance or generic service entry | | Remedy | Dealer confirms which recall was done and whether the engine was replaced | Seller can’t establish what happened | | Build date | Dealer verifies involvement and relevant engine dates | “Too new for the recall” is the entire explanation | | Oil cap and insert | Evidence matches the documented remedy | Mismatch without a dealer explanation | | Current condition | Independent inspection finds no unresolved symptoms | Knock, unexplained codes, or refused inspection | | Coverage and price | Written eligibility and competitive total price | Promised coverage hasn’t been verified | ## **Frequently Asked Questions** ### **Is a truck with a replacement engine safe to buy?** Not necessarily. An engine replacement alone may not fully address safety concerns, as NHTSA has opened an investigation into post-recall repairs that don’t address problems with GM’s 6.2-liter V8. Before buying, review the replacement records and have an independent mechanic inspect the truck. However, these steps can’t provide a guarantee against future engine failure. ### **Does the recall apply to 2025 or 2026 models?** No. For now, NHTSA Recall 25V274 covers only certain 2021–2024 GM vehicles. NHTSA’s ongoing investigation extends into the 2025 and 2026 model years, but this doesn’t mean the recall will be expanded. ### **Can I check the fix myself?** You can take steps on your own, including reviewing recall repair orders and checking for an oil cap replacement and the owner’s manual insert. However, getting more information about test reports and identifying engine replacements may require professional help, including support from a GM dealer. #### About the author – Patrick Peterson ![]() Patrick has been with GoodCar for 7 years, after previously working as a professional vehicle appraiser.
