More than 1800 Mazda6 vehicles have been recalled in Australia over a potential engine defect.

2008-mazda6-1

In total, 1821 Mazda6s produced between January 8, 2008 and February 12, 2008 have been recalled. All affected vehicles are second-generation Mazda6 models equipped with the L5 Series 2.5-litre petrol engine.

The official recall notice on the Australian Competition & Consumer Commission website explains:

“It is possible that one of the circlips that retain the piston pins within the pistons has been incorrectly installed.

“If the clips fail during use, this may result in the piston pin sliding out of position and contacting the cylinder wall. The resultant damage could cause the engine to stall (if this should occur, the engine will not restart).

“In a worst case scenario, engine parts (conrods) may crack the oil pan on the bottom of the engine or the cylinder block, causing oil to leak.”

Owners of affected vehicles will be contacted by mail and are advised to contact an authorised Mazda dealer for replacement of the piston ring and connecting rod assemblies with revised ones.

The repair will be conducted at no charge to owners.
