The defect and its consequences

The outlet flange is part of the fuel-tank arrangement. Jaguar’s report described cracking that could allow fuel odour or liquid fuel beneath the rear of a stationary vehicle. An amber malfunction indicator could also appear. Escaping fuel, in the presence of an ignition source, created a fire risk.

Engineering analysis during September found that fuel-system operating pressure could exceed the design specification in some conditions, potentially stressing the flange. That explanation belongs to this identified component and campaign; it is not evidence that an unrelated fuel smell on another vehicle has the same cause.

Why service history affected the population

The US filing separated 4,152 vehicles from the 2010 model year and 43 vehicles from the 2011–2012 model years that had received service replacement parts. Most factory-affected vehicles had been manufactured between April 2009 and January 2010. Supply of the relevant aftermarket parts ended on 23 October 2012.

Consequently, a later model year did not automatically rule the campaign out. Equally, being an XF within a broad date range did not automatically establish inclusion. The precise vehicle and any replacement-part history were important.

The investigation preceded the recall decision

Jaguar opened an internal investigation on 9 July 2012 after monitoring warranty data. The issue progressed through technical review in September, and the Field Review Committee decided on a voluntary recall on 18 October. At the time of the filing, Jaguar reported three field reports and 17 warranty claims worldwide concerning outlet-flange cracks, with no reported accidents, fires or injuries attributed to the issue.

Those numbers describe information available to the manufacturer at that point. They are not a lifetime total or a present-day assessment of every surviving car.

National records describe different populations

Transport Canada’s campaign 2012365 was originally published on 25 October 2012 and listed 2010 and 2011 XF vehicles. Australia’s J027 record, published on 11 December 2012, identified 63 affected vehicles. These national populations should not be combined into an unsupported worldwide total.

The US report described replacement with a revised-design outlet flange at no charge under the campaign. Its original notification timetable was a plan, not proof that every repair had already happened. For an individual car today, campaign eligibility and completion must be checked through the manufacturer or an authorised representative in the relevant market.

A historical recall is not a remote diagnosis

A warning lamp alone does not identify a cracked flange. Fuel odour or visible leakage also requires assessment of the actual vehicle rather than reliance on an archive article. This record explains the historical campaign and its remedy; it does not establish that JLRTECH can perform an official recall repair or determine whether a particular car has already been repaired.
