General Motors has issued a recall for approximately 12 diesel-powered SUVs that were mistakenly fitted with incorrect fuel tanks during dealership service visits. The mix-up affects select Yukon, Escalade, and Tahoe models equipped with 3.0-liter Duramax inline-six turbo diesel engines and could potentially cause fuel leaks in serious collisions.
The Parts Mix-Up Explained
The recall stems from a flaw in GM’s parts ordering system that led dealerships to install wrong-sized fuel tanks during routine service. The incorrectly installed tanks lack essential safety components found in the original design, including specific vent tubes connected to the fuel pump system.
The Safety Risk: Without proper venting, the mismatched tank and fuel pump combination could potentially leak fuel during a severe crash, increasing fire risk for occupants.
Which Vehicles Are Affected
The recall covers approximately 12 vehicles across multiple model years:
Affected Models:
- 2022 and 2024 GMC Yukon (diesel)
- 2021 Cadillac Escalade (diesel)
- 2021 and 2023-2024 Chevrolet Tahoe (diesel)
All affected vehicles are equipped with the 3.0-liter Duramax inline-six turbo diesel engine and received incorrect fuel tank installations during dealership servicing.

How the Problem Was Discovered
The issue first came to GM’s attention in June 2025 when a Chevrolet dealer noticed that a replacement fuel tank installed in a 2022 Tahoe didn’t match the original specifications. Further investigation revealed the parts ordering system error that led to the wrong tanks being shipped to dealerships for service appointments.
Current Status and Safety Record
GM emphasizes that no incidents or fuel leaks have been reported from any of the affected vehicles to date. This recall is entirely preventative, addressing a potential safety issue rather than responding to actual problems in the field. The recall specifically affects only those vehicles that received fuel tank replacements during dealership servicing, not all diesel-powered SUVs of these model years.

What Owners Need to Do
GM will begin mailing recall notices to affected owners starting November 3, 2025, though service technicians have already been notified and prepared to perform the necessary repairs. Once owners receive their official recall letter with specific instructions, they should schedule an inspection at an authorized GM dealership where they will receive a free fuel tank replacement if their vehicle is confirmed to have the incorrect tank. For any questions or additional support, vehicle owners can contact GMC customer service using the toll-free number provided in their recall notice.
Free Repairs Guaranteed
GM will replace all incorrect fuel tanks with properly designed units at no cost to owners. The company has already briefed its service network on the repair procedures to ensure quick resolution once owners bring in their vehicles.
Broader Context: GM’s Recall Year
This fuel tank issue adds to GM’s challenging 2025 recall record, which began with approximately 600,000 vehicles recalled for engine problems earlier in the year. While this latest recall affects far fewer vehicles (just 12 units), it highlights ongoing quality control challenges in GM’s parts distribution system.
Bottom Line
While the scope is small—affecting only 12 diesel SUVs—this recall underscores the importance of proper parts management in automotive servicing. Owners of affected vehicles should watch for GM’s recall notices and schedule repairs promptly, even though no incidents have been reported to date.
The good news: GM caught the error through dealer feedback and is proactively addressing the issue before any safety incidents occurred.
