Infiniti M35/M45 Maintenance and Repair



  • I hope not to bore you folks regarding my quest to have a great music experience, but I had a revelation today. With the cooperation with my Lexus dealer and the infiniti dealer we had a M45 and Lexus GS 460 side by side to listen to one cd of my choice. Do not laugh, but I choose Michael Jackson greatest hits. Both sounded good, but finally through the wisdom of my wife we realized what was "wrong" with the Bose. Per my wife of 20 years who loves music; "the music sounds like it is in a box with the lid on". After listening to 10 songs in both cars she is right. I was able to adjust the Mark Leveinson's midrange to make the music come alive. Also, with the Bose I had to adjust the base, treble, and fade to different settings for every song. The Mark Levinson required very little adjustment after the first song. I am actually disappointed; the m45 is a blast and I always feel conected to the road. Sorry Infiniti and Bose, but maybe in 3 years when my lease expires the sound system will be "better" FOR MY HEARS.

    I have a 2008 M35x after having a 2006 for two years. Both have passenger seats that squeak when making turns. When I had the `06, I brought it in to have the squeak checked, took a ride with a tech, and as you would expect the seat made no noise. Since I spend more time going straight than turning, I let it go. My 2008 does the same thing, but I can't be bothered hoping to have it make noise when I bring it to the dealership. Even so, I'm wondering if anyone else has had this problem or if I just have a spooky one. ons/emotorcons/emo_confused.gif

    I had a 2006 M35X that went off lease in February. I had the Bose with DVD audio deck and speakers in the seats. The sound quality was so poor I thought I needed a hearing aid and the steering wandered so much I thought I needed a brain scan. The ride was like an oxcart.

    I now have an Audi A4 2.0 Premium+, quattro sports package. The Symphony sound system is fabulous and I never heard Audi's top of the line Bang & Olfsoon system. The steering and handling is like a go-cart and the ride allot better than the M. The mileage is 30% better.

    Bose is overbranded and over advertised. Any high end audio dealer will laugh if you mention their name.
  • Just saw your post. You may have already tired this but deactivate your lane departure system and see if you notice the same problem.
  • barryend; you are SOOOOO right regading the Audi. I drove the same model you purchased except with the B&O System. Goodbye Bose. I am actually embarassed that I was considering the M35, it is too much marketing and not enough performance.

    Hi y'all...after changing my oil and filter on my '07 M45, I decreased my intervals to 2500 miles since I'm now doing mostly stop and go driving. How do I activate the changes? Is there a re-set procedure that the owner's manual left out? I'm goin' bananas over this!

    What is an acceptable amount of oil consumption in 3000 miles?
    Thanks BMW

    The service intervals are in one of the menus...don't remember exactly where. Did you look in your owners manual?
  • shmangshmang Posts: 297
    Just click on the oil change reminder and it will prompt you to reset - it is right above the place where you adjust the interval. Click Reset and it will clear the mileage to zero... and will remind you in 2500 miles.
  • shmangshmang Posts: 297
    The general accepted standard is less than 1qt per 1000 miles for performance car, but, with modern engines, I would say less than 2 qts for 3000 miles is acceptable.

    The comparable model Audi is the A6, not the A4.

    We'd pretty much decided on the A6, but our dealer couldn't locate an acceptable car on dealer trade. So we're now driving an Infiniti M35x, which my wife and I both love.

    I know the owners manual does not recommend the use of the lighter for powering things like radar detectors, etc but has anyone had any experience with doing so?
    I just thought I would check before trying it and blowing my car up.

    I see what you mean. The owner’s manual isn’t forth coming with technical information.

    Call the dealer and ask the Service rep. what the cig. lighter circuit is rated for. Ten amps, 15 amps or 20 amps? Whatever that amount is, make sure the components you plug into the lighter socket are less then that amount. You should be just fine with a radar detector. The M35/45’s are great to be driven and the detector is helpful to have.

    You won't blow the car up - you'll blow a fuse if you plug a component in that draws to much current for that circuit.

    Wishing you good luck.

    about blowing it up. The question really is if the fusing/circuitry for the cigarette lighter is different than the fusing/circuitry for the accessory socket and why Infiniti designed it that way if in fact that is the case.

    I found my new M45X with a blown 10 Amp Fuse for the cig lighter. Replaced the mini fuse and now plug my cell phone into the socket. It works fine,no fuse problems and no smoke so far. Is this safe. Thoughts?
  • osbornkgosbornkg Posts: 30
    There should be no problem with a cell phone plugged into the socket. Biggest problem is when you answer and talk on your phone while driving. Does your cell phone have Bluetooth? If, so pair it with the Bluetooth in the M45 and you can answer and talk hands free. Good Luck.
  • Recently returned my 2006 M45 sport off lease. It was flawless, one of the best of 10 Infinitis Ive leased/owned since giving1993. Retired now and dont need three cars so didnt replace it but miss it a lot... 2008 QX and G37 coupe are nice for their purpose but miss the M45 on long trips when storage isnt needed. Hope the new one is slightly larger, truck and back seat wise and not out of orbit price wise.
  • Yes, the "M" is a very fine car. Our 07, M35 purchased in June of 07 now has 47,000 miles on it. Just a great road car. We feel blessed to travel this great country in such a fine car. No major maint. as yet, other then oil/filter and air filter. Just great. Thanks for your comments - we feel the same.
  • Sorry for the 2 month delay. I no longer have the the Infiniti so I don't follw these boards. I deactivated the lane departure warning shortly after I leased the car in 2006. It has no bearing on a mechanical problem. The 2009 A4 with sports package is superb. The Infiniti steered like a boat.
  • I have owned a few cars in my years...Prior to my M35X it was Lexus LS 430. I have approx. 10k miles and the "fake" wood on the doors is peeling off in large pieces. I knew the lexus was the same type of product, but it at least made you feel like you had real wood. I love driving this car, but the little stuff that goes wrong does not indicate luxury.
