What's wrong?
The fuel supply line on the 2021 XT5, XT6, and Acadia carries gasoline from the tank toward the engine. It is part of the fuel delivery system, and its job is to keep fuel moving through a sealed path while the vehicle is running or being started. The line and its fittings have to sit fully in place so pressure stays contained.
On affected vehicles, the fuel supply lines were not attached and seated correctly. That means the connection did not lock into its intended position at assembly. A line that is not fully seated leaves the fuel system without the seal and retention it was designed to have, so fuel can escape from the connection instead of staying inside the line.
There is no warning sign before failure. If the line starts leaking, an owner can notice a fuel smell, visible fuel, or trouble starting, but the recall record does not list a dependable early symptom.

| Units affected | 572 |
A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific SUV is included.
What's the safety risk?
Improperly attached or seated fuel supply lines can loosen or separate, causing a fuel leak and increasing the risk of a fire. Schedule the dealer inspection soon, and stop using the vehicle if you notice fuel odor or leakage. Repair will be free at any franchised Cadillac dealer once available.
What should I do?
- Check your VIN to confirm your 2021 Cadillac XT5, Cadillac XT6, or GMC Acadia is included in this recall.
- Watch for the July 1, 2021 owner letter from GM, or use your VIN result if the letter is missing.
- Contact the matching franchised Cadillac or GMC dealer about the free fuel-supply-line inspection and replacement that fixes loose or separating fuel lines.
- Bring the recall notice if you have it. If not, reference recall number 21V422 when you call.
- Avoid parking near ignition sources until the dealer confirms the fuel supply lines are properly attached and seated.
What happens at the repair
At the dealer, a Cadillac technician inspects the fuel supply lines to confirm they are attached and seated correctly. Any fuel supply line that does not meet the recall repair standard is replaced. Because the remedy status is not listed as open in this record, treat the final dealer repair as free once available rather than assuming an appointment can be completed now. Parts and labor are covered under the recall when the repair is open. Owner letters were mailed on July 1, 2021, and the dealer can use recall 21V422 or GM recall N212335590 to confirm the repair path.
