Applies to
DB12 (2023-present), Vantage (2024-present), DBX (2020-present).
VIN applicability: Refer to the separately published Aston Martin affected-VIN list. This quarantine notice gives a combined build window; use the model-specific build dates in RA-03-1973 and a dealer VIN check instead of applying that window to every model.
Years beside model names identify production generations, not confirmed affected years. For a specific car, confirm the VIN with Aston Martin or an authorised specialist. Do not assume every vehicle in the model family is affected.
Issue and owner context
Aston Martin publishes a dealer quarantine notice for oil cooler hose replacement on affected DB12 and latest-generation Vantage vehicles, addressing the same oil-loss safety concern as RA-03-1973.
Reported symptoms
- Low oil level or oil-pressure warning
- Oil leak from an engine oil cooler hose
- Smoke from the engine area
Aston Martin's repair
Replace the oil cooler hose set on affected vehicles. The DB12 and Vantage workshop reference is 03.02.GM. This is a separate dealer document for the oil cooler campaign, not an additional independent defect.

Confirmed factory information
The document record below was checked against the named source. Aston Martin is the publisher of the factory document.
Archived under NHTSA campaign 24V712000 alongside RA-03-1973. The recall action and quarantine notice cover the same safety concern.
The two-page quarantine notice is preserved unchanged. It states a combined October 2022 to July 2024 build window for DBX707, DB12 and Vantage; that combined wording must not be read as each model having the same production start or affected years.
Confirm the VIN and current parts with an Aston Martin dealer. Catalogue generation years do not establish that all DB12 or latest Vantage vehicles are affected.
The factory document also covers DBX707. This catalogue addition is scoped to DB12 and the latest Vantage.
