Mazda Problems

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.

As Mazda pointed out to you the fuel consumption figures they publish are the results of laboratory tests mandated by the government. Every carmaker has to do the test and publish the results on a sticker on the windscreen of the car. As such it shouldn't be taken as fact that you will get the same figures when you drive the car in real life. The figures are given as a guide and for you to use when comparing one vehicle with another. There are many things that affect fuel economy, so you need to check everything that might cause your consumption to be higher and make sure you are doing everything you can in your driving environment to minimize your fuel consumption. Having done all of that it does seem that your vehicle is using too much fuel, as you say. I would engage your dealer and ask that he set up a fuel consumption test that measures the actual amount of fuel you are using so that both you and the dealer are in agreement about the fuel being used. You will then have a common basis on which to discuss what action you and the dealer could take going forward.

Cars built after 2003, such as yours, must be fitted with a system that has been emissions approved, and I would very much doubt that anyone has mixer system that is approved for your car. The mixer system is old technology and is nowhere nearly as good as the newer injection system. Although injection systems are more expensive they are the best option.

Sounds like you need to have a transmission specialist take a closer look at it. For starters, the transmission fluid doesn’t simply disappear without reason, there has to be a problem. I would have the auto serviced and the fluid changed.

You need to find out where the leak is occurring. It’s possibly from the windscreen seal.

If the coil were faulty I would expect it to play up all the time, not just first thing in the morning. Get the transmission checked, particularly the fluid level.

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 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.

It's most likely the window winder motor that's the problem and you should be able to switch the motor from one of the other doors to the driver's door.

I think you can assume it is over-servicing. Some dealers encourage their staff to try to sell customers services they don't really need. Injector cleaning is one of them that regularly crops up here at Carsguide. You did the right thing by questioning the caller instead of blindly agreeing to the work.
