A retired mate of mine bought a brand new MX5 in August last year and is now afraid to use it as he can never be certain that it will start. As they are retired they tend to go away for two to three weeks at a time and when they get back the Mazda's battery is always flat.

Luckily they also have a Merc that doesnt suffer the same problem.

The MX5 has only done 2500 miles since new and because of the lack of starting issue they are loath to use it more.

I told them that they should get the car back to the dealers as there must be something wrong with the battery for it to go flat so quickly and so he took it to their supplying dealer. This is what the result was from an email he sent me.

"Have been to the Mazda dealer and guess what - all mx5's have the same problem, or as they put it "Oh yes they all do that - you can park an mx5 for between 10 to 14 days but after that you cannot expect it to start because it has only a small battery". They offered to charge the battery and check the car but were not hopefull of a solution. I am contacting Mazda UK next week to see if they agree with this analysis."

To all 2007/8 Mazda MX5 owners, do you have problems with the battery life ? Do you have to make sure that you never leave the car for more than 10 days?

I would really like to hear if this is a common problem?

Cheers,

Tony

That's complete bks. My car often sits for a number of weeks and always starts perfectly. The only reason the battery would go flat is if something is draining it. An alarm shouldn't make a battery flat in 2 weeks unless it's been fitted incorrectly.
Either there is a wiring problem in the car somewhere or the battery is faulty.

I suggest that they take it directly to a Mazda dealer and get them to check it out.
My feelings entirely but the Mazda dealer says that all MX5 batteries go flat in 10 to 14 days as its "a small battery"........

Put it this way, my mate paid over £17k for a brand new car he can't leave for more than 10 days before the battery goes flat. The dealer says this is normal and acceptable.

What does the MX5 posse think?

Cheers,

Tony

Thanks guys, I've told my mate that the concensus of opinion is that the dealer is bulling him.

My mate has a Phd in electronics so I hope they dont try to baffle him with science as they will just embarrass themselves.

Cheers,
