Mazda—Mazda6 (GH1051) Vehicles
What are the defects?
It is possible that one of the circlips that retain the piston pins within the pistons has been incorrectly installed.
What are the hazards?
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.
What should consumers do?
Owners of affected vehicles will be contacted by mail.
Owners are advised to contact an authorised Mazda Dealer for replacement of the piston and connecting rod assemblies with revised ones.
