Chevrolet Tahoe and Suburban 6.2L Engine Failure: Lemon-Law Options
If the 6.2L L87 V8 in your Chevrolet Tahoe or Suburban failed or keeps having problems after the recall inspection, oil change, or engine replacement, the recall work counts as a repair attempt and you may have a lemon-law or Magnuson-Moss Warranty Act claim. The recall does not waive those rights. A 2025 or 2026 Tahoe or Suburban with an engine failure can have a warranty claim too. In the recall or out of it, we help GM 6.2L L87 owners nationwide under the federal Magnuson-Moss Warranty Act.

The Tahoe and the longer Suburban share the L87 and are listed separately in GM's recall report: 44,814 Tahoe and 22,169 Suburban SUVs with L87 engines built between March 1, 2021 and May 31, 2024. NHTSA's investigation covers every 2021 to 2026 Tahoe and Suburban with the L87.
| Model | Recall 25V274 model years | NHTSA investigation EA26005 model years |
|---|---|---|
| Chevrolet Tahoe | 2021, 2022, 2023, 2024 (44,814 vehicles in recall 25V274) | 2021, 2022, 2023, 2024, 2025, 2026 |
| Chevrolet Suburban | 2021, 2022, 2023, 2024 (22,169 vehicles in recall 25V274) | 2021, 2022, 2023, 2024, 2025, 2026 |
- Chevrolet Tahoe: 2021, 2022, 2023, 2024 (recall 25V274); 2025, 2026 (under NHTSA investigation EA26005)
- Chevrolet Suburban: 2021, 2022, 2023, 2024 (recall 25V274); 2025, 2026 (under NHTSA investigation EA26005)
Only the 6.2L L87 is included. Tahoe and Suburban models with the 5.3L V8 or the 3.0L diesel are not part of the recall or the investigation.
What the recall and the NHTSA investigation say about the Tahoe and Suburban
For both SUVs, the recall remedy is the same: dealer inspection, then dexos 0W-40 oil, a new filter, a new oil fill cap, and an owner's manual insert, or a replacement engine if the engine fails inspection. NHTSA opened EA26005 on August 20, 2026 after hundreds of post-remedy failure complaints, and expanded the scope to L87 engines built after the recall window, which brings 2025 and 2026 Tahoe and Suburban SUVs in.
A family vehicle that loses power
Tahoe and Suburban owners often carry a full load of passengers. GM's own recall report says an engine failure while driving means loss of propulsion and a higher crash risk. Under MMWA, the seriousness of the defect matters when deciding how many repair attempts are reasonable, so a loss-of-power defect in a three-row family SUV may need fewer chances than a comfort feature. Write down every time the SUV lost power, where you were, and who was in it. That detail helps.
Is my 2021, 2022, 2023, 2024, 2025 or 2026 Tahoe or Suburban 6.2L covered?
A 2021 Tahoe 6.2L, 2022 Suburban 6.2L, 2023 Tahoe 6.2L, or 2024 Suburban 6.2L is in recall 25V274 if its L87 was built between March 1, 2021 and May 31, 2024. A 2025 Tahoe 6.2L, 2025 Suburban 6.2L, 2026 Tahoe 6.2L, or 2026 Suburban 6.2L is not recalled as of September 25, 2026, but it is within the scope of EA26005 and likely still under factory warranty. Check the VIN.
What to do if your Tahoe and Suburban engine fails after the recall

- Get a repair order for every visit showing the date, mileage, your symptom description, and the recall number.
- Keep your oil change and maintenance records and every towing and rental receipt.
- Log each visit in our repair attempt log and check open recalls with our recall lookup tool.
- Do not sign a release or goodwill agreement until a lawyer has read it.
Frequently asked questions
Are the Tahoe and Suburban treated differently in the recall?
No. They are listed separately in GM's recall report, but they share the L87 engine and get the same inspection and remedy.
Is a Tahoe with the 5.3L V8 affected?
No. Only the 6.2L L87 is in the recall and the investigation.
Does a loss-of-power defect need fewer repair attempts?
It can. Under MMWA, what counts as reasonable depends partly on how serious the defect is, and GM itself says an L87 failure can cause loss of propulsion. Results depend on the facts.
Can I get a rental while my Tahoe or Suburban is in the shop?
GM's recall materials say courtesy transportation is available for recall repairs on vehicles within the related warranty coverage period. Keep receipts for anything you pay yourself.
