Chevrolet Malibu Start Up/Ignition

I just purchased a used 2005 Chev Maxx with 12500 miles about 2 months ago. I've put about 3k miles on it. My problem has 2 issues. The first is when I go to start the car,after I turn the key and before the engine engages I get a really bad shake that rattles the whole car. This happens about 6 out of 10 times when I start it. The second issue is I get a periodic rattle in the right front. Here again it does not happen all of the time. I've had it into service and they couldn't find anything wrong. It's still doing both things. Anyone else having that problem? Any suggestions? Thanks, fmm06418

  • My wife's 04 Malibu does the same thing on start up occasionally. Not as often as yours but with hers is it usually accompanied by a major transmission issue where it doesn’t want to shift and when it does the car jerks so hard it makes me glad I'm wearing a seatbelt.

    Had 2 different dealers attempt to solve these issues along with a steering problem but after performing items on TSBs, multiple software updates, and a new BCM the problems still remain. :(

    We love the Malibu and there is not a more loyal GM customer than myself but the (good natured) ribbing from my import driving in-laws is starting wear thin. :sick: Although my father-in-law is on a wait list for a Sky!
  • This is the first GM product I've had in 25 years. The last was a 67 Nova. I really like the way the car drives and the interior is very comfortable. Since I'm 6'4" the leg room is very important to me. As for the shaking when it starts and the intermitant rattles, I'm just keeping my fingures crossed and hope if it's something major, it will be fixed under warrenty.

    Mine shakes like this on start up sometimes too - twice this week already. My dealer says it is because the car has electronic ignition and I am holding the key down too long. I really dont know that I am and I try to be conscious of that on start up (when I remember) but it still happens.

    As for my other shaking problem, I took the car in Friday. The dealer says asphalt sealer was on the caliper and brakes and that caused them to stick. I don't know if that would cause my two incidents two weeks and 1000+ miles apart. They cleaned it off. We will see.

    The dealer also said the rotors and brakes were fine. They must not have road tested it because I still get a nice wobble when braking at higher speeds. Still only 21K.

    Holding the key down too long? On the 04+ Malibus once the key is turned to "start" the PCM takes over and cranks until the engine starts or 4 seconds (Maybe lower). You can just turn the key to start and let go and it'll continue to crank or you can hold it at start all day and it'll still stop cranking once it hits 4 seconds or the engine stops. Also, your wobble when braking might be warped rotors.

    >asphalt sealer

    What does that mean? Is it the tar from a road that got onto the the brakes? Or is it some undercoating they applied to the car?

    >Still only 21K

    The brakes will be fine until 36000 is passed. They they will find there is a problem from having been overheated, but it won't be covered by warranty.

    Good luck with this one. It was like pulling teeth getting my dealer to feel the problem. All the while, I'm thinking, "Do you not have any senses? How can you not feel that shaking?"

    On the bright side though, since they fixed it its been fine for 10K.

    Be absolutely sure your tires are torqued correctly. I had this problem from time to time and every time I noticed it, it was because the tires had been severely mis-torqued.

    Fortunately once the tires were torqued properly, most of the shake went away. The brake rotors are indeed flimsy.

    Regarding the shaking when braking.... I have had this problem on a couple occasions and it usually starts after the dealership has had the wheels off for a rotation or other service. My opinion is the service tech isn't torquing the wheels with the proper sequence and torque when re installing the wheels which is warping the rotors causing the vibration.
  • paopao Posts: 1,867
    you are correct..it appears that the wheels must be properly torqued or you may experience some warping..and that vibration......insist they are hand tighten and torqued...and not with an air gun

    Many shops don't like to have to use a real torque wrench to tighten lugs. They talk fast like a teenager caught using all kinds of excuses.

    When they use a torque wrench they should use the star pattern and go around twice. If I don't trust the shop, I come home driving gently on the brakes, and jack the car up at each corner to take the weight off and loosen and retighten with my own torque wrench. Current rotors on LeSabre have 65K on them. The wheels have been off every 6-7K miles for rotation and other times on my own.

    Tar I suppose. The problem hasn't happened in the last 10 days.

    I figure the same thing with the 36K mark. I will take it back before then and invite them on a test drive if need be. The local dealer is right off the the highway.

    We have a problem on start up randomly. The car shakes and runs on without starting. Turning it off and re starting almost always works fine. It is an 04 maxx LS. We have less than 5K left on warranty and it will not reproduce this problem often enough for the dealer to attempt service. The dealer thinks it may be a fuel problem but can't find anything wrong. Help.

    is it from a cold start, a lukewarm start, or a hot start?

    Maxxes and many cars have trouble starting if you run the engine a short distance, then park the car. The problem seems to be incorrect temperature analysis. The ignition and fuel system get confused and send the wrong mixture to the cylinders.

    This problem has showed up on an old prism and camry I used to own.

    "many cars have trouble starting if you run the engine a short distance, then park the car."

    That's just an accepted part of life here in an area where we have such huge changes in temperature season to season. In the period of a given year we deal with a range of outside temperature from -40C in winter to +40C in summer. I'm always amazed ANYthing works at -40.
    If you've ever had to sit in a car that's sat outside in -40 overnight, you'll know what I mean. If you havent, then you cant imagine it. Factor in windchill and we can get to -50, 60 or lower.
    My past challenge has included making a carbeurated engine with an electric choke work ok for that wide range of temperatures.... yikes! That makes newer cars look very good.

    Just so you dont get feeling too bad for us here, today it's +30C, which equates to HOT.

    BTW I saw an update in dealer info regarding complaint on starting - where it seems like starter staying engaged after engine running. Nothing available yet but looks like calibration update expected in June. I will keep an eye out for updates.
  • shadow5599shadow5599 Posts: 101
    The starter seeming to stay engaged for a few seconds too long, I've had that happen several times since I've owned the car, about 2 months now.
  • thorfamthorfam Posts: 2
    This is probably a better description of my problem. The starter staying engaged. It will not always keep running under these conditions without turning the key off and re starting. It seems to happen most often with a cold start.
  • I really need some good advice here. I have a 2001 chevy malibu with roughly 100,000 that I just bought And like so many others on here I im haveing problems starting the car. It cranks but will not turn over no matter what i do. The only way i could get it to start is to spray starting fulid where the air filter is ( maybe it is flooding) I think it may be the ignition system or the fuel system but to be perfectly honest i dont know much about cars.Please help! :confuse:

    Malibugirl2001, depending on how recently you mean when you said you "just bought" the car, I might want to go back to your dealer if you bought it from a dealer. If you bought it privately, or if it's no longer covered by any warranty from a selling dealer, I'd take it to a good shop to have this trouble diagnosed. This is not going to be a do-it-yourself repair, in all likelihood.

    If I were guessing based on what you say, I'd say you may have a bad fuel pump.
  • well I just bought the car from a private party so i im sol but i have been reading on here and i think it is either a theft system chip or maybe a fuel in jector problem. at any rate i have no clue and i will probaly have to go to the shop. i was just hopeing that i could figure it out and not have to pay that much
