I agree that in your case it seems excessive, but service intervals are determined for the average use. You could service it annually, but be warned that if you did that and were to have a problem that resulted in a warranty claim you might be rejected because you haven't serviced it according to the book. I would service it according to Mazda's recommendation until the warranty runs out, and then consider moving to longer service intervals.
It's obviously concerning you, so you should get it resolved. I would suspect that the dealer has driven around the block and when it hasn't happened he's declared it checked out. Dealers today aren't really equipped to investigate problems and resolve them, if it doesn't show up on their diagnostic equipment or happen all the time they're stumped. You could try an independent mechanic who specializes in Mazdas, or if you prefer to stick with your dealer sit down with him and find out what action they already taken to find the problem and then map out a plan of attack to fix it going forward.
I think you’ve got very good grounds to argue that it should be fixed under the warranty. The problem was first reported when the car was under warranty and the dealer clearly did not fix the problem, and you are perfectly entitled to have the problem fixed. Also remember that Mazda is required by law to provide you with a car that is fit for purpose, and in this case, your car is not. Don’t be fobbed off by the company’s suggestion that you are not covered.
A failure of a water pump shouldn’t cause major internal engine damage. I would expect the failure to cause the engine temperature to climb and the warning light to come on. Providing you address the problem and don’t drive the car to destruction there won’t be any serious damage done. But I would be concerned that you have failed three water pumps in such a short time; that is not normal, as you appear to have been told. Have the dealer explain to you why he believes it is normal, and justify to you that it won’t continue to happen.
The tyres have probably scalloped, which is a problem on the Mazda 3 and would explain why the noise has got worse. You could try the Michelin Pilot Sport 3, PS3, which is regarded as a quiet tyre.
Road noise from the rear is a problem many Mazda3 owners have complained about right from the launch of the car and there’s not a lot you can do. Fitting different tyres is the first thing that most people do, and like you have found, they make little if any difference. I would suggest you could try applying some noise deadening material to the panels inside the car, particularly in the rear, which seems to be the main noise generation area.
It's clearly over-servicing, something some dealers try on from time to time. You did the right thing in questioning the need for it; hopefully you didn't do ahead with it.
The diesel and petrol engines in the current Mazda3 have timing chains.
The alternative fuels people have told us that it is not correct. All petrol companies must display notices on pumps when ethanol is present in the fuel.
