MG3 fuel tank strap bolt recall: why a fastener defect does not mean ordering a tank

If a used MG3 being prepared for resale has a “fuel tank recall” on record, do not immediately put a tank assembly on the purchase order. The Australian action concerns the strap retaining bolts. Separate the fastener remedy from the condition of the tank itself to avoid turning a small component requirement into an assembly purchase.

How a bolt defect can affect the whole tank

Notice REC-001632 states that the fuel tank strap retaining bolts may be defective and fail, allowing the tank to move or even detach from the vehicle. If detachment causes fuel leakage, it may lead to a fire or accident.[Official defect description][S09]

Although the fasteners are small, an inspection cannot be limited to visible damage on the outside of the tank. Purchasing and repair decisions need to address the mounting points identified in the notice, rather than just compare tank appearance.

The official remedy is inspection and replacement of the retaining bolts

The notice instructs owners to contact a dealer for vehicle inspection and replacement of the fuel tank retaining bolts.[Official remedy][S09] It does not require a new tank for every vehicle.

If the vehicle has other damage, the repairer can document those findings and additional requirements separately. The word “tank” in the notice title is no reason to bypass assessment of the fasteners. Equally, a routine tank inspection does not establish that the specified bolts have been dealt with under the campaign.

Do not select generic bolts by appearance

Since the action concerns retaining bolts, obtain the component requirements for the vehicle before purchasing. Similar-looking old parts or threads are insufficient grounds for substitution. The main notice does not provide dimensions, strength grades or tightening requirements; a supplier should not fill in those parameters for the manufacturer. [To be verified]

For used-vehicle preparation, record whether the campaign has been completed, which mounting points were addressed and whether there is additional vehicle damage. Distinguishing these points makes the next repair handover more useful than simply recording “tank checked”.

Scope and verification

This article concerns only Australian action REC-001632／MG3STRP. The notice was originally published on Jun 24, 2021 and updated on Jun 25. The notice year is 2021 and it covers 3,917 vehicles; this is not presented as a newly issued recall. Check the vehicle against the [official individual VIN list][V79].

No public data was available for bolt specifications, torque, OE numbers or additional repair criteria after tank damage. [To be verified] No individual VIN lookup was performed. For ordinary compatibility or interchangeability, check the VIN and local manufacturer parts catalogue; contact the local authorised representative first about the recall.

For confirmed requirements for ordinary fuel system fasteners, use the parts enquiry page.
