Hey nissmazlover my radio stopped working as well this morning. I got into my MZ5 to go to work turned it on and the radio greet it me like always...HELLO, then my iPod was playing because I can see on the display the timer going on track #85 but no sound was coming out the speakers, I then tried to switch to AM/FM and it would not do anything, so the last move was to turn it off and It did turn off. Only problem was that the radio would not turn on again, nothing, nada, zilch! So I quickly remembered your post and I turned off the vehicle completely, let it sit for 30 seconds or so and turned the vehicle back on, but.....nothing still, dead. Needless to say I commuted to work with no stereo... that SUCKED! I got to work parked and went into work. I just came out after two hours of my MZ5 being parked and turned off to check again and what do you know...VOILA! the radio works. Weird, but I guess that makes two of us. BTW mine is a 2006 MZ5 Touring Auto with the 6CD in dash and auto temp A/C.

I've got a 2009 Mazda5 GT, about 3 months old. Radio stopped working a couple of weeks ago. I had to shutdown the engine to make it work again. Today, happened to me again. Tried to shut it down for more than 5min, but this time, nothing. I tried about 4 times.
 
I'm hoping it's gonna come back cause I can't live with no music at all. At least give me the radio!
 
I'll take it to the dealer if it still doesnt work tomorrow.
 
Anyone who had this issue got it fixed? By the way, any of you guys having any mods? I've got HIDs and I was worried if it could cause an electrical issue of some sort...

I own a 2007 Mazda 5 Furano and yesterday my dashboard lights decided to flash on and off randomly along with the "beep" to tell me my seat belt wasn't on when it was. The most curious thing though was all dials kept flicking up to max, for example the speedo said I was doing 140mph when I was actually only doing about 20, including petrol gauge, then flicking back to zero then righting themselves.
This happened over 20 times (i got fed up counting) over a short distance of about 8 miles.
None of the external lights seem affected, there is no problem with the power steering or power assisted brakes and the radio, windscreen wipers and heater all work fine. The indicators were a bit confused though, even though on the outside of the car they were indicating right, inside the car they were indicating left, then right, then left again.
 
It only seems to happen when accelerating from standstill to about 30mph and happens more frequently when the car is warmed up.
 
I have taken the car to the dealer who are clueless (not sure if this is the normal state for them or just because of this problem as I haven't tested them out before).
 
Any Ideas????

The needles behavior indicates low voltage in the dash. It happened to me twice in a Mazda when the battery was drained. All gages would go up and down.
 
I hope this clue helps.

That sounds possible, the garage haven't come up with a solution yet and they have had my car for 5 days, no joy.
I will mention this to them tomorrow.
Did you manage to sort the problem out?
Thanks for the respose by the way

Oh yeah! I fugured it out! I stoped leaving the lights on at night!
I was just pointing out that the needles go up and down when there is low voltage in the dash. The cause in my case was a dead (almost) battery - user error.
 
In your case there could be a bad ground connection, a defective voltage regulator that suplies current to the instrument cluster or something else that lowers the tenssion.

Got my car back today!!
 
One of the black covered wires to the dash (from underneath the manifold) had been cut somehow and was only allowing power through when the engine was in neutral or higher gears when it had less vibration. In lower gears the engine vibration was separating the two ends of the wire and causing the needles on the dash to go weird.
 
The guy at the garage (Simon) was made up that he had found the problem.
I was pretty stoked too
 
Thanks for your help, the garage said it gave them the idea for looking at the wires.

HURRAY!
I have a question of my own. I have a brand new 5. On the lower pannel over the left leg, driver side, very near the hood release, there is a small black... cube screwd on the plasric. There is a wire going from it in the back of the pannel. This seems to be added in hurry, like an after thought. It's not the ODB connector. Anybody knows what this is?

#25 of 37 Electrical Problem - Battery situation etc by aubie53

Dec 12, 2009 (4:02 am)

This week I replace the battery in my 2006 Mazda 5 ( 3 1/2 Year Old Battery). First of all location of battery was in the wrong place and difficult to get to in order to replace. However, now the battery light stays on and the battery apparently is discharging. Before the battery light was not on. When I charge the battery back up will go for 3 to 4 days but then dash panel lights start to flicker, ABS , fluid level light and other dash board lights flicker or stay on. Lose the function of power steering. Gears shift hard. Has anyone had this problem and if so what was the solution.
 
Thanks

I have not seen this, but it sounds like you have a bad connection to the battery, or a bad battery or maybe you connected the battery wrong? Like + to the - (chasis) terminal?
