  • hi, barryend,

    You got the exactly same answer I got. It looks infiniti is trying to avoid this issue.

    I have a 06 M45 sport that has noticeable driveline whine at 40mph and 80 mph. The dealer states that this is a normal characteristic of the car. Anybody else notice this in their car?

    As always, when the service manager says "they all do that" or "that's normal", you say ok...let's find one in your used car lot and drive it just to verify that "they all do it" ....make him come with you. If he refuses, then ask to see the infiniti regional rep on his next pass thru the dealership and then take the infiniti service rep out driving with you.

    I have a 06 M45 and when ever I adjust the steering wheel (up, down or telescope), it makes squeaking noises. Has anyone had this kind of issue? If anyone does, what is the fix?

    TIA
  • I forgot to add that when I saw the service manager last week they took me out in another '06 M35 Sport that was in for service (for some other issue I was told). It too showed the same grabby/wandering steering but all that really tells me is that the problem is pervasive to the '06s. Is anyone driving '07-'09s experiencing the same steering problem/defect or has Infiniti quietly fixed the issue in the newer models?
  • My 06 M35x did the same thing. The dealer lubricated it and it stopped for about a year, now it's starting to do it again, mostly when it's cold. Other than that, not sure what another fix might be.

    Thanks. I will ask my dealer to lubricate it and see how long it will last...
  • can someone help, my seat will not lean forward, all the buttons are working, seat will go forward and back but the back rest will only move back, has anyone had this problem how did you fix it?

    Well, I take the car in this morning to have the steering wheel noise checked out - thought it just need to be lubricated or something,no biggie. This afternoon, got a call from the service adviser, the motor to move the steering wheel need to be replace and they ordered the parts, should be all good next Monday.

    While doing the inspection, they want to replace the coolant, tranny fluid, air filter and driving belts and stating there are some bad cracks on the belt. I know for a fact that the coolant was flushed 3 month ago and I myself replaced the air filter last month, I just basically declined all those service requests.

    Now, I am curious: Has anyone replace their driving belts? If you did, at what mileage & age of the car? It seems too early consider the car is only 3 years old and has about 43k miles on it.
  • my '07 M35 has 27k and the belts are making a squeaky noise - more so when cold. Dealer told me the pulleys were fine but I should think about replacing the belts for "a couple of hundred" bucks. At 27k !!?? Isn't it under warranty? Nope - wear part. I hate #$%^&-ing wear parts!

    Then he said, well if you get some belt stop-squeak spray at Pep Boys and spray it on the belts they'll quiet right up. They show no signs of wear so that's prob what I'll do.

    My experience with american cars is belts every 45-50k miles whether they show signs of wear or not. You don't want to get in the middle of tim-buck-too and have the altenator belt snap. Probably at night. If you're gonna keep it a while I'd say 43k is getting to the point of consideration. BUT if you can see cracks on the INSIDE of the belt or any fraying on the edges it's time to change them regardless of mileage. Rubber belts will degrade at different rates depending upon your climate, humidity, is it garaged every night or out in the weather ... this type of stuff.

    I'd be interested to know what they charge you, so let me know if you get it done.

    I've been told that the reinforcing fibers inside the belt end up getting brittle as they age (fatigue from being flexed), and the belt can break with no obvious wear...so, follow the suggested time frame for replacment, regardless of what they look like.
  • shmangshmang Posts: 297
    Wow, that is strange. I had Nissan and Honda before and their belts do not need to be replaced until 105K (and Infiniti share parts with Nissan). As a matter of fact, I have a 10 years old Honda that the driving belts has never been replaced. Although there are a few cracks on the inside, they works fine. I do the same type of driving and keep all my cars in garage. So, I guess it is either Infiniti use inferior belts or the stealership is trying to make some profit out of us. :mad:
  • Speaking for myself, I will not do any major preventive maintenance until our 2007/M35 has between 50k-60k miles on it other then oil/filter and air cleaner. This has always been my practice since we started with Japanese cars some 30 years ago.
  • shmangshmang Posts: 297
    I agree with you. I normally just do the oil/filter and air filter until about 45K, then I replace coolant and brake fluid. By about 60K, have the tranny fluid, power steering fluid changed.

    Granted I do not keep cars as long (used to keep them for 10-12 years), but I have never need to replace the driving belts before 90K miles on Japanese cars. So, this seems fishy to me. I will have to look at the belts Monday to see what is going on.

    I agree with the other posters...check the serpantine belt and if it's not worn, it's more than likely OK. Also, if it does break, you won't hurt the engine (assuming you turn the car off before it overheats)...it will just be awkward explaining to the "meaningful other" why you didn't replace it as you are waiting for the flatbed tow truck.

    Don't use the belt spray...it's a temporary fix, at best. If you can't tighten the belts and get rid of fan belt noise, replace the belt.

    The only belt I change religiously when it's recommended is the timing belt. If that goes and you have an "interference" engine your engine will be destroyed. I don't know if the M35 or M45 are "interference" engines.

    At the top of the front window where it meets the roof I have a black rubber seal that runs all the way across the front of the car. I noticed a big section of it is flush with the top of the window and the roof while other sections are pushed in and not flush where the window meets the roofline.The dealer said its normal, but I'm wondering where the water goes at the spots where the rubber is pushed down in the opening. Anyone else have this issue and more importantly, any problems with water leaks?
  • shmangshmang Posts: 297
    If you are talking about the M, then, no, it should not be pushed in. Mine is flushed all the way.

    What year and model is yours?
  • c5_4func5_4fun Posts: 59
    thanks. It's a 2006 M35x. I was going to walk a dealer lot and look at a few others as the dealer noted on my repair note that it was a "normal condition".
  • shmangshmang Posts: 297
    I see. Mine is 2006 as well (M45 though, but oth.er than the engine, it should be the same). So, it is definitely not normal. Have it checked out while it is still under warranty.

    Well, the other day, my wife bought me a few music CDs and I like them, so I thought I will put them in the CD player (6 CD changer with MP3). But, the strange thing is: some of them will not play and show a message: "Track information not available" while the others plays just fine.

    I thought it might be the slot, so I swapped them and didn't make any difference. The ones works still works and the ones doesn't doesn't. I can play ALL of them in my regular CD player at home, so all CDs are good CD.

    So, is there any trick that I am not aware or is there a work around?
