Mazda UK have phoned me today and it seems my dealer has been telling some porkies.

Mazda Uk have said they have been informed by the factory that a fault exists with some mazda 2 alarm systems manufactured since june of last year they have now found the fault and fixed it and are producing replacement parts. There are many hundreds of people waiting for parts not 7 or 50 as stated by my dealer.
They know of no factory faults that would affect fuel economy or that would affect the rear suspension and all m2's do not in fact have a knock from the rear suspension as my dealer said.
My dealer had not told Mazda UK that the vehicle had already been rejected so they sent the parts to repair the car.
Mazda UK did not refuse to replace the car as they do not get involved with customer rejections as any contract is with the dealer and not Mazda (what I told my dealer)
Mazda Uk were not impressed that the car was delivered damaged and then repaired by non mazda approved repairers and then damaged again by the dealer.
Mazda Uk were not impressed about the amount of visits I have had to make back to the dealer or the quality of service I have received from my dealer the dodgy courtesy car did not go down well.
Mazda Uk will now contact my dealer and state my concerns to my dealer and re inform them that the vehicle remains rejected and tell them that it is their problem to sort out.
Mazda are not happy bunnies with my dealer I wouldn't want to be in their shoes when they call them.
I am awaiting a phone call from my dealer if they have the balls to call me after they have been caught lying to their customers.
