Mazda6 Engine Problems



  • mazda 6 stales out 10 min later starts up its the 4 cyl 2007 any ideas no check engine light scared to drive might break down

    My 2004 6 cyl Mazda 6 blew the engine at 81k. Had been well maintained, with oil changes well in advance of the recommended 7500 mile interval. No smoke, no warning lights, no signs of trouble. Just died.
    Mazda's customer service really sucked. No offer of any assistance. Even though out of warranty, a car should not blow an engine witht his few miles, and they should back their product up. They even went so far as to tell me in a letter that "even if under warranty, this would not have been covered". The inference being that I had service done by someone other than the dealer.
    The point is, DON'T BUY A MAZDA!

    Pretty sure only the 6 cylinder was a Ford Duratec no longer for last couple of years), while the 4 cylinder has always been a Mazda design.

    The new 3.7L is a Duratec design as well. It is built and tuned by Mazda in Japan now.

    This has happened a couple time recently. When the fuel level is below 1/4 tank,
    when accelerating, there is a hesitation as if low fuel pressure. Fill tank and the problem goes away. Stopped at a dealer today, and he was thinking it could be a purge value starting to fail, having to do with the evaporative emission controls.
    I wouldn't think it is the fuel filter getting clogged, as the fuel level shouldn't affect the pressure. Anyone had an issue like this?

    any check engine light? What codes?
  • No, no check engine light. Car has been fine all week, with fuel level above 1/4. I could try to go to an Autozone or such, as they can read codes. Haven't tried this yet.

    I bought a 2006 Mazda 6 in October 2009. 1 week after I purchased it, the car would not start. I had gone to an appointment and came back and battery was dead for no obvious reason. I had not left any lights on and the doors were not open or ajar. It started fine wth a jump. One month later, my main headlights went out and a sidemarker light. A couple weeks later, both my fog lights went out. Then my high beams wouldn't work, but the next day they started working. During this three week period, my CD player also stopped working for a day, then started working again. The dealership replaced some bulbs and two fuses that had burnt out.

    Three months later my main headlights and side marker lights went out again. Then a few days later, the engine died at a stoplight. I was able to immediately re-start the engine and the Check Engine light came on upon start. I drove it straight to the dealership. They looked at it the next day and the Check Engine light was not on and they could not find a code registered. They tested the battery and alternator and both were fine. They told me that the previous owner had hard-wired HDI headlight bulbs and that was causing the lights and fuses to blow. They had to do some re-wiring but they ended up replacing the two mains with stock bulbs. That night I drove the car to the store after dark and the lights were very dim. When I came back to start my car 15 minutes after being inside, the car won't start. The dash lights and radio are working but engine won't crank now.

    Any suggestions?

    Well, Some times I am a dumb [non-permissible content removed]. While the solution to my engine noise was rather simple, reading the horror stories on this thread had me really worried.
    I had a noise coming from the engine. It seemed to happen mostly during excelleration or anytime the transmission had to down shift. Reading this stories seemed like I was in big trouble. Basically everyone that had an engine noise either said change the PCV or get a new engine. Everyone that road in my car thought the engine was about gone.
    I noticed that the noise would stop when I went over a bump at low speed or when I drove over a rise in the road.
    It was the engine mounts! I changed the one on the passenger side and the torque mount. The torque mount was not too bad but the one on the passenger side was toast. It was rattling around like crazy.
    I hope this help someone.

    I am familiar with this issue,not with Mazda but with Chrysler . the problem may be the main ground from the engine block to the body , some times it's to small . replace it with a size that seems more adequate. This may fix all your troubles.
    good luck and zoom zoom.

    I've hesitated, but just threw in the towel with Mazda. I've owned 8 Mazda's over the past 26 years, had mostly good experiences up until this 2004 Mazda 6 V6 Hatchback. I need to mention, I was a Service Manager at a Mazda dealership and left the automotive industry in 2000 after just too much pain and suffering and watching what used to be a good company start going down the slippery slope. I can't tell you how many times I went to bat for customers and won with Mazda, transmissions, engines, you name it, anything under 100k or 6 years, I could get them to pay for out of goodwill for the original owner for almost anything, especially if they were a loyal owner (had owned more than 1 Mazda) But there came a time where they started becoming more difficult to get to step up and "own" a problem for well maintained vehicles, which was right around the time I left the industry. That was over 10 years ago.
    This vehicle had synthetic since 1000 miles out of the box, over maintained, at my request, by the dealership which is my M.O. Minor problems which I considered to be "normal", but there were consistent coil failures causing secondary ignition problems..which were corrected right away each occurance. Ended up needing a new Cat at 99k, fought tooth and nail to get Mazda NA to pay 50% of the part under goodwill. BTW, I had an extended warranty which covered thousands of dollars of failures after the Mazda warranty expired...but it ended at 100k..guess what, 101k, I check the oil, down over almost 3 quarts (occurred in say a few weeks since I had checked the level prior), I noticed an unusual noise from the engine, took it in 1,000 miles early for it's oil change within the week, needs an engine..big surprise right? You can find them, but to spend 5-6k installed (I wanted a new radiator and hoses etc to do it right if I was going to keep it)seems silly on a vehicle that is worth 9k at the most retail. BTW, PCV valve was the cause of the oil "loss". I know better than to waste my time with 100k, they'll do absolutely nothing to help a customer out of goodwill, don't ever even consider it over a 100k, you'll just waste your time. If it was under 100k, I would have fought tooth and nail, and if I was lucky, I might have got them to pay 50% for the engine only, which Mazda sells (long block) for $4700...just for the part, so you do the math....used ones are between $1800-2500. Still a loosing proposition, unless you want to do the work yourself, which can be a bit of a pain in the [non-permissible content removed]. All the salvage yards/companies know this engine is in demand.
    So, that's it for me for Mazda forever, just wholesaled out of this car to the dealer, I don't want or need to deal with selling it privately. (it still runs, making a racket, blows smoke at cold start.. but it will fail entirely, the only reason it didn't blow up I suspect was the synthetic oil). I have had Toyotas for years, and even given the recent and not so recent challenges they've had, I still find their product to be far superior to Mazda. (it still runs, but it will fail entirely, the only reason it didn't blow up I suspect was the synthetic oil).
    A big disappointment for someone who used to be an Ambassador to the company, and a very big fan. I'd encourage anyone to understand, no matter how well you take care of a vehicle, if it's starved for oil for any length of time, it's going to become a problem. Always Check your oil at least once a week, or daily if you drive 100 miles or more...its the only way to possibly prevent something like this from happening and catch the loss or consumption early. Additionally, don't hesitate to replace a PCV valve at your 30k services or every 2 years, it can't hurt. I feel like a bit of an idiot for letting it go for more than a few weeks without checking the oil, because actually I probably could have prevented the failure, but most car owners can't or just won't ever have this kind of routine. It's been a sad week for me, but Goodbye Mazda, forever.

    Well folks there you have it. Same message from this last guy as I said from the start of this thread 136 messages ago. I've had 7 Mazdas he's had 8. I'm an Engineer, a mechanic & a racecar driver and he's a former Mazda Service Manager. Mazda said my problem was my doing without doing teardown / root cause annalysis. Which is fostered by "Jesta" saying Mazda has walked away from peoples problems. No more Mazdas...... ever!

    While it is unfortunate to have this major problem at just over 100K mi, I don't think it is reasonable to expect Mazda to cover anything with that many miles under the factory warranty. I had a Ford Windstar with gasket problems at 90-95 K mi, they did nothing even though the very same engine in other Ford vehicles was given extended coverage for these gaskets. I thought it was ridiculous that they could, for example, say the very same part was defective if the engine was put in a truck but just fine if the engine was put in a minivan.

    You did not indicate if the extended warranty was from Mazda or a 3rd party. Since you were barely over 100K mi, I think there is more of an issue there. But if you had an extended warranty to 100K mi, why did you fight to get Mazda to pay for the cat at 99K, shouldn't the extended warranty have paid for that?

    Do you have an update to the fix to the hesitation you were seeing? My wife's car is doing the same thing when it gets to 1/4 tank.
  • seanakioseanakio Posts: 4
    I have had my mazda6 for about 2 years now. Its a 2004 6-cyl hatchback w/ a manual trans. Ive been hearing a clicking or ticking sound when the car is on sitting in one spot. I can't seem to pin point the noise but its starting to freak me out a bit. Anyone heard of this problem or is it even a problem? My first impression is ticking=no good. Any help or info would be much appreciated.

    I had the same problem in the last couple of months. Did you ever get it resolved?
  • sharvillsharvill Posts: 3
    I had the fuel pump replaced and it fixed the issue.
  • onlamonlam Posts: 13
    Did you have a CEL code? Mine was throwing out a P2179 everytime when the tank gets about 1/4 full.

    there is a service bulletin on fixing a camshaft ticking noise. Willing to bet that's your problem, it's common. keep in mind, we have the same model, and I had to repalce my engine at 81K, and Mazda offered NO assistance of any kind.
