#24 of 73 ignition system
Aug 11, 2008 (11:43 am)
I have a 2004 mpv. Had it in the shop this week to have a tranny range switch replaced do to a bucking problem. That didn't fix the problem with the van. After 3 days I finaly got an anwser from the dealer that it is a noise conditioner in the ignition system. I would like to know If any one has heard of this before. I have worked on cars for 10 years and have never had this problem on a car, van, or truck. Thanks for the input.

Did you find out about the headlights. I have a Mazda 1994 MPV and the lights come on by themselves, unless high beams are on and now the alarm is now activated by itself, so I have to reset it by the battery every time I get in the car!

#27 of 73 My MPV 2003 - Coils?
May 18, 2009 (9:50 pm)
I have not posted in a bit about MY problems - latest is the CHECK ENGINE light coming on again! Two times in the past 2 weeks - once for a misfire on #4 plug. Took to my trusty local service person who said it may get moisture in the coil assembly due to a bad rubber seal? We decided against doing anything, resetting the light and it seems fine now. It did stumble for one day but finally dried out I guess. Ugh! This has happened off and on since I got this unit new in 2003. It usually happens in a heavy rain where all of a sudden the engine will start stumbling until it dries out again. Great Mazda design I guess??
Second Check Eng. Light came on again - this time due to a "Random Misfire". Could not pinpoint which location it was though. This rig is a bundle of puzzles and mysteries for sure. When it runs it is sweet yet - after 122K miles!! When it starts acting weird, I get nervous and think I'm on borrowed time!
Anyone else out there have this stuff happen to you? Anyone still have their MPV after this many miles??? I think I'm getting to be in no man's land now!! Many of the people who use to post here are long gone now due to selling off these puppies!

You probably need to go ahead and replace #4 coil. You don't want to be out in a heavy downpour, or on a trip, and have it start acting up. It's easy to replace 4,5 and 6 coils.

SAME PROBLEM!!! The dealer acts as if I am crazy. I ended up changing out the #4 plug/coil. I've had several quirky issues with this MPV, which will be my last. There is an electrical problem with my MPV and now I suspect that it is common among the 2003-2004 model years. Now, my A/C is draining the life out of my second battery in 5 years. I feel as if I am treating symptoms because Mazda and its service providers cannot figure out the actual cause.
I'm selling as soon as this latest issue is resolved.

We have the exact same issue with our 2001 MPV how was your issue resolved? The dealer wanted 3000 to fix ours as well. This certainly should have been a recall as a major safety issue.

We had the [sometimes dramatic!] 'bucking" problem, also called "rough shiftting," when our 2004 MPV was about -or less than- a year old; we were told somewhere, I can't remember exactly, [but NOT by Mazda!], that it was a software problem & the dealers had a "software fix" that would work; We took it to the local dealer, who knew about it, and told us they installed that "software fix" & it generally has worked well since then. A little later, we also had them put in a new, supposedly very sophisticaed synthetic trannie fluid from BG. can't say that it's done anything we notice, but the tranny works well so far & their claims *sound* impressive. In the past I've used one of their products for manual trannies I thought was very impressive. the autotranny fluid is, however, fairly expensive.. anyway, the software fix really should work, try it & let us know, OK?.
#33 of 73 All Dashboard warning lights are on
Nov 11, 2009 (3:54 pm)
After my mechanic fixed a couple of things related to a check engine light, some sensor problem I believe, all the warning lights on the dash stay on continuously now. He said it was probably that the computer needed to be reset and said it would probably be $100 to have Mazda do it. Does this sound right? Anyway I can do something about it myself? Is it fuse related?
It's a 2002 MPV LX, original owner, about 70k miles.
