#38 of 43 Re: Battery drain on Mazda3? [roadburner] by dudehau Jun 15, 2009 (7:01 am)
Replying to: roadburner (Jun 04, 2009 8:07 pm) Got a 2009 Mazda Speed3 2 months ago and having issue with battery draining within 24hr period.   It started with the "Engine" light indicator coming on. Took it to the dealer and they couldn't figure out the problem. They concluded that it was a glitch and reset the code. The next week, I left the car sitting no more than 2 days and the battery was drained. Took it in and they replaced the battery, concluding that the battery had a faulty cell.   Again, I left the car sitting for about 1 1/2 day while going out of town. Once again the battery was drained and I had to jumpstarted. My conclusion is that it is not the battery and the dealer have no clues what the issue is. Something is obviously being left on and is draining the battery.   I'm taking the car in again and will give an update soon.

It shouldn't be hard to isolate the problem; it takes a lot to drain a battery in 24-36 hours. Simply just start pulling fuses and relays until the current draw disappears. My son left the door open on my MS3 one night and 12 hours later it fired right up. Replies to this message: dudehau (Jul 29, 2009 1:37 pm) roadburner (Sep 24, 2009 7:58 am)

Replying to: roadburner (Jun 15, 2009 9:50 am) I've taken the car to the Houston Jeff Haas dealer 3 or 4 times already. Each time they hook the battery up to some kind of machine to track any draw from it and each time they tell the me the same thing which is there is no draw they can detect. They can't find the source of the drain and so they conclude it's a bad battery. I'm on my third battery with a car that only have 3000 miles on it. They try to tell me that the new battery they put in my car didn't have enough time to charge itselft because I only drove the car for 45mins and let it sit for 2 days. Sounds like BS. A new battery should not drain in 2 days.   I've been patient but after the third battery and the problem is still there, I have to escalate the issue. I'm no auto genius but I new from the start it was not the battery. I didn't want to be a difficult customer, so I went along with their BS diagnostics. They were very relunctant about giving me a loaner car too.   I decided to take my car to the Clearlake Mazda dealer and give them a chance to resolve the issue. I explained the history of the problem and my frustration with Jeff Haas Mazda. I told them quit focusing on the battery as the culprit and put the focus elsewhere. Basically do something different then just replace my battery.   The rep. from the Clearlake dealer was very understanding and accomodating to my needs. She took the car in and offer me a loaner without any hesitations. They let the car sit for 2 days and they confirmed that it would not start.   Initially, they thought maybe it was because my doors was not shutting tightly because of the Thule roof rack I installed. They make sure the doors were shut tightly and let the car sit at the dealer for 2 more days. Again the car would not start.   They finally narrow down the culprit to the junction box. It was explained to me that the Mazda 3 will go into a sleep mode after you shut off the engine for some set amount of time and my car was not doing that. They order and replace the junction box and let the car sit for 2 days. This time the car started. Problem solved. Thanks Phyllis and Clearlake Mazda.   I'm glad I bought my car at the Clearlake Mazda dealer and not Jeff Haas.   Peace, Replies to this message: roadburner (Sep 24, 2009 7:58 am)
#41 of 43 Digital Instrument display by joeduppa Sep 21, 2009 (12:03 pm)
HELP!!! second time this has happened. Dealer fixed it the first time. Maybe it's something I can do on my own. My digital readout of the instrument display (clock,temp,audio etc) has gone haywire. All I see are numbers continously looping. Does anyone know how to fix?

#43 of 43 Battery Drain on Mazda3 - It's the Radio? by dudehau Sep 25, 2009 (8:03 am)
After 3 new batteries and a new electrical junction box, they figured the problem to be the radio. They sent a Mazda engineer out and found that the radio was coming on and drainning the battery. It took about six trips to the dealer for them to finally figure it out.
