Mazda 3 FAQs

Check out real-world situations relating to the Mazda 3 here, particularly what our experts have to say about them.

• My Mazda 3 ran out of diesel and now it won't start

  Many diesel engines don't appreciate being run out of fuel and will exhibit this behaviour if you allow them to run dry. That's because a lot of diesels have a fuel system that doesn't automatically prime itself and start pumping fuel once it's run dry.

  As a result, some diesel cars have a hand primer under the bonnet that allows you to prime the diesel fuel pump and get going again. But modern ones like your Mazda often don't, and priming them involves a specific procedure to get the fresh fuel from the tank to the engine. Most workshops will be able to carry out this job for you, but simply continuing to crank the engine with your fingers crossed will do nothing more than flatten the battery.

• 2017 Mazda 3 having trouble starting

  Cars have never been more dependent on their electrical systems than they are today. Sometimes, changing a dead battery can lead to the sorts of problems you've noted, and while it could be something more mechanical, there's one thing you can try at home before phoning the mechanic.

  Disconnect the battery and leave the car for at least half an hour. Then, reconnect it, start the engine and go for a drive of at least 30 minutes. That will usually be enough to perform what's called a reset and may solve your problems.

  If not, you need to have the car scanned at a workshop to see what problems the on-board computer has identified.

• Should I buy a 2018 Mazda 3 Astina or a 2019 Mazda 3 GT25?

  Both these cars are well equipped, well built and have a good reputation in the trade. Which means you won’t regret buying either of them. In turn, that means that the decision will come down to whether the extra standard equipment of the Astina model outweighs the factory warranty of the SP25 GT.

  The extra gear in the Astina amounted to 10-way adjustable powered front seats with a memory function, specific 18-inch alloy wheels, a sunroof, radar cruise-control, forward obstacle warning, adaptive headlights, lane departure warning and lane keeping assistance, and smart brake support. Whether you reckon that standard gear is better than a year of so of factory warranty is entirely up to you. The only problem being that when the warranty runs out, you might start to think differently about the relative value of the two cars.
