Mazda CX-7 Starting Problems



  • barb34barb34 Posts: 5
    I agree! I have had nothing but problems with the 2007 CX7 we bought new to bring to Europe with us while stationed here. Since getting here the AC Compressor has gone out ($1,000 no warranty thank you), shocks, brakes, vent air, defroster leaks all over the floor, lights and alarms that go off for no reason, and now the darn thing won't start. I understand brakes and shocks...but the rest of it?? PLUS, and here is the real kicker, Mazda will not ship to military overseas, nor will they honor warranty to military overseas (contrary to what the dealer says, they'll say anything won't they?). Wouldn't have bought a Mazda if I had known. It is very unsettling to be in a foreign country unable to speak the language well with a car that is so unreliable.

    Fun to drive, but so not worth it. I think I am going to follow your lead and put a lemon air freshener in it....maybe then it will get the message LOL.
  • In the last 6 times that I have filled up with gas, 4 of those times my "07" CX7 would not start. It would cough and sputter and not start. If I would push down on the gas peddle, I can get it to start and it will stay running as long as I keep the RPM's up. After apx. 5 minutes, it runs find and will not give me any problems until I fill it up again. I took it to a mechanic and their were two codes he pulled. One was that it was lean at start up. Can't remember the other one. After the engine light was reset, it came back on about 50 to 100 miles latter. Will take back to mechanic soon to see what the codes might say. Mechanic says he has never seen any problems like these and is very confused as to what it might be. Me too!!! Anybody have any thoughts???
  • I had sputtering problems when my CX7 reached about 70k miles (I now have 92k miles). I have started using a fuel injection cleaner that I add to my gas every 5,000 miles. I also do not let it run below a 1/4 tank of gas any more (I find the sputtering is worse when it is below 1/4 tank).

    In regards to the engine light, for me, it has been the gas cap. A friend of mine who also has a Mazda with high mileage (not CX7) has also had the same problem. I just make sure to push in the gas cap and turn it so it clicks 4 - 5 times. The light rarely comes on any more, and when it does, adjusting the cap fixes the problem.
  • i have a 2007 cx-7, i parked the car for the week end. went out to start, car will start and run for about 3 sec. and die, no default codes are coming up, has any body else had this problem. everthing checks out but still will not start, the shop i have it at is stumped, could this be a security problem? :mad: I willn't take to mazada, they rip you off :confuse:
  • Hello, I have a mazda 07 cx7 (aka nightmare) Your post was the only post I saw that fits my problem exactly..just wandering if you got yours fixed and if so can you please let me know what fixed it and the details.. I would really appreciate it. Thanks so much =) Melissa :confuse:
  • Heres my full story..My 2007 mazda cx7 will crank and run for about a second and then die...cannot tell if any warning lights are on due to the fact it wont stay on long enough. It first started while i was driving it.. I goosed it down a strait a way and it I attemted to restart and it would start for a second to only to die again. It drove pretty good up until that moment, However I have spent 2 grand on a new timing chain and accutator about 3 months ago.. I am really regreting getting this car last year after seeing all the head aches people are having with the 07 models. And to add insult to injury I just bought brand new tires and had the oil changed and air filter changed. The car just didn't appreciate it :( :confuse: if anyone has any suggestions please help..I really appreciate it!
  • My car has been fixed. The problem was the fuel pump,is runing perfect now.

    I have not been able to solve my problem yet and am not willing to let the mechanics start putting new parts in it, if they don't know for sure. My starting problems only happens after I fill the tank with gas. I tried it with and without the engine running while filling but every time when I try to start it after filling the tank, it acts like it has ran out of gas. The only way to get it to start is by pushing on the gas pedal for about 10 seconds during that time it coughs and sputters. Then it runs just fine until I fill up the tank again.
  • Well got great news!! A mechanic friend of ours came and looked at our 07 cx7 and it took him 10 minutes to fix the problem. Come to find out..when I had the oil changed they also changed the air filter, the old one had lots of bugs in it.. well what happened was when ran the car fast that blowed a leftover moth into the air flow sensor and blocked the prongs..and therefore was not getting all he done was blowed out the moth now our car runs and it runs perfect!!! I know if we had of taken it to the dealer they would have charged alot! so greatful to our friend who was so knowledgeable. If anyone is having starting issues you and needs to check your air flow sensor to see if it is bad he said to just unplug it and if the car runs even if it runs rough just as long as it runs..thats the problem.. fortunately we didn't have to buy any parts! I hope this helps. :D

    I need some HELP!!! I can't get my car to start, all the lights work, battery is new on the car and remote. It makes no noise at all when I try and start it...... Any suggestions???

    If the battery is new and you can't even get the car to crank over-- the connections on the battery must be loose or coroded. Check the connections-retighten-and try again.

    I'm JUST having this problem myself. Not sure if it's the same.

    Occasionally, the car just won't start. No "clicking" like a dead batter no nothing. BUT, the radio, lights, etc. all work.

    I've had it into Mazda (third time today) and they keep telling me there's no problem. They called a while ago and said there's a bad wire somewhere and in certain positions it will cause the car not to start.

    Previously they checked battery, started, solenoid, connections, etc.

    Hope they fix it this time, because I'm getting gun shy every time I start the car. I'm afraid of getting stuck again!

    Hello Grebor,

    We are having the same issue when we fill up with gas only then it runs fine. I have not taken it in but seems like something with the fuel pump or maybe when we had the air filter changed at the valvoline oil change place.

    Did you have any luck locating the problem?

  • greborgrebor Posts: 3
    We never did figure out the problem. It doesn't do it all the time, but still sometimes will not start after we fill it up with gas unless you push down on the gas pedel just enought to keep the RPM's up for about 5-10 seconds and then it seems to run fine untill you fill it up with gas again. I have just been living with the problem because I have yet to fine anybody that can tell me, with any amount of certainty, that they can fix it.
  • Get a new battery. Or at least check the terminals. About 6 months ago, mine started to corrode a lot (on the neg terminal) ... after cleaning it up, it lasted a good 6 months before it corroded over again and wouldnt start. (I had power in the car though...theres just not good enough connection). Cleaned it up Tuesday and then by Saturday it was majorly a mess again. I think there may have been a leak at that terminal. I hear the OEM battery is not that great anyway. Should solve your problem. My Cx-7 starts so much better now! And i'd had the starter, alternator, wires, etc...all checked months ago, and everything was fine. New battery it is.

    I am having the same problem with my 2007 Mazda CX7. About 5 months ago, it was running great and when I turned it off it would not start- power to everything, all lights windows and remote worked but not even a click when trying to start. It seemed like the car was left in drive and the ignition would not work. I tried unhooking the battery ( to try and reset the computer), rocking the car, investigating fuses, moving the shifter from park to neutral with no luck. I left the car in the parking lot and next day I arrived with some tools to check out the starter - I thought I better try and start it one more time and it fired right up after sitting all night. It gave no more problems until last night and the same thing happened - I tried a few things and nothing worked and then in the morning it fired up ( this time I had to try the ignition 3 times before it worked) - It ran fine today and has started on each occassion today. I phoned 4 Mazda dealerships today and no-one could give me a solution. Did you find a solution for your Mazda Cx7 not starting? I was told to 1) check the connections on my starter for corrosion, 2) check the shifter cable where it goes into the transmission and see if it is sticking giving the car the signal it is still in gear 3) in the mazda 3 it was the indicator in the shifter so perhaps I should check the shifter. I'm at a loss for a solution. I may call a few more dealers tomorrow for ideas. Can anyone help me out?

    while stopped at light (at an incline) my car literally stops (pressed gas but no luck) and would not restart. I turned the engine off to restart the car, but what happened surprised me, the engine would not turn. the car came on, but the engine wouldn't start. had it towed to a mechanic who told me its the starter not an electrical problem.

    Is the mechanic correct?

    the car has over 80K miles, but I don't expect these issues at all....

    i am having the same problem , but my wont start at all. tried cranking several times and no luck!

    any help will be appreciated... the local mechanic is telling me its the starter. based on the various post, it may not be the starter at all.
  • I took my cx7 in for the sputtering issue after filling up with gas and they fixed the problem.

    It was a purge valve stuck open causing excessive vacuum leaking

    part is L33L-18-740B VALVE SOLENIOD
