Infiniti M35/M45 Maintenance and Repair

  • Asd, some car manufacturers wouldn't even acknowledge a problem, let alone replace the whole transmission. You brought it in for an oil change and they spotted a problem. I wish I always had 5 techs looking at my car, LOL! Infiniti's policy is to give you a loaner while your car is being repaired, so what's the problem?

    BTW, my wife's Saab transmission went after just 1500 miles, they didn't replace it, just rebuilt it.
  • I have a G35 coupe with the 19" alloy wheels. When I bought the car, the dealer offered me wheel and tire insurance for around 6$ per month. Having bent alloy wheels in the past, I went for it. You might see if your dealer offers anything similar. It replaces wheels and tires damaged by road hazards. Sounds like it is what you need.

    Good luck!

    I bought that coverage ... and it includes new tires at all four corners when I turn it in at the lease's end, no cost to me. I have not quite 10K miles on my M35 Sport now, and I'm half way into the lease so I'm hoping all I have to do is drive on "slicks" to the bitter end. I've been seeing posts of 22K miles to tread wear ... I should make it. I keep my tires hard ... 38 psi ... should make it. Bart

    Lemon laws are variable from state to state ... but a recent state Supreme Court found that Lemon Laws do NOT apply to leased vehicles. If you're leasing you will likely be out of luck.

    If you've bought the car and IF a problem can't be resolved in "X" number of visits, or if the number of disabling problems is such that the vehicle's quality is suspect the laws will help you. More than that, Infiniti itself may opt to take the car back, for a price of course.

    A friend of mine had a MB SL55AMG that had all sorts of problems ... and MB was unwilling to settle a dispute with him until he assured him that their legal defense bill would be greater than the cost of a new car if they didn't take his car back ... even AFTER it had been wrecked! Once they knew HIS legal budget was ample to beat them up they agreed to replace his car w/ a new one. He told them out front he would pay a few $K difference ...

  • ... and it includes new tires at all four corners when I turn it in at the lease's end, no cost to me.

    Blov8r, are you sure, or am I missing something? Assuming your lease is 24 mos. that's only $144. How can they afford to replace even one tire at the end of the lease, let alone all four? That doesn't seem right even if its $6 per wheel.
  • blov8rblov8r Posts: 567
    I'm sure. It's a 36 month lease and for covering condition issues at lease end I'm paying $900 over the course of the lease, and that included window tinting! They're betting on the average lease of that duration going at least 12K/year so the vast majority of people who pick up this protection will have to replace all tires before lease end. It covers dings and dents, upholstery rips and stains, windshield cracks, etc. It's not from the manufacturer .. it's an after-market money maker for the dealer but in my instance it will likely cover me completely and be a loser for them. (I do NOT believe it covers bent wheels.) Bart
  • Thanks for all the responses. I'll look into the aftermarket protection, but after a year and half and 20K miles I don't know if I'll qualify. Fortunately, I have not experienced any other under carriage damage to the vehicle. I've started looking into aftermarket wheels which is probably the way I'll go ($1000 - $1200 for a set compared to $3000 for OEM wheels). The mfg standards appear to be higher than Infiniti's as well. If anyone has experience with the aftermarket it would be much appreciated. I'll advise my final decision. Steve

    Unfortunately, 3400 or so rpm in 5th gear around 80 is normal. The car is geared for performance, not economy and this has been an ongoing gripe with me since the G35X I traded in for my M35X. At 70 it's almost 3000 RPM. I would think the car needs a long 6th or so, as most cars are turning around 2000 at 70 or so.

    I did have an interesting experience last week however, I started the car, it stalled, and I started it again--the key was in my pocket, no trouble code given. When I put it in drive, it went into safe mode--RPMS top at 1800 and the car won't go over 40. After 12 miles or so I put in reverse and drive again and it ran normally--went right to the dealer, no codes received-they think I am crazy, but it happened.

    I am on my third radio now--audio problems with the first and CD player died on the second--took over 3 weeks to get a radio!

    ASD--what did they tell you was wrong with the tranny, and if they haven't please let us know what you learn!

    No one will sell you protection once the car's been in service for any length of time ... kind of like a health insurer excluding pre-existing conditions. My coverage is through an outfit named Mechanical Protection Plan (MPP) out of Shawnee Mission, KS. It's called Executive Lease Coverage and covers up to $2,500 for paint damage, dents, scratches, chips, rust, etc. Plus head lights, tail lights, bumpers and bumper trim, brake rotors, drums, pads, and shoes. Shocks. Interior upholstery damage. Windshields and windows. Side view mirrors. Alloy and steel wheels! Excess tire wear w/ less than 1/8" remaining tread. Belts and hoses. Audio system. Essentially gives me a "walk away for nothing" option.

  • I had luck using the AUX mode.
    purchased a 1/8" headphone to RCA connector and attached it to the audio inputs behind the center console used for the DVD player.
  • With about 1000 miles on the vehicle, my 2007 M35X began having an electrical system failure in the console. All controls would freeze or blank out. The A/C and heater controls would be frozen in place as they were in at the time of the electrical fault. The Navigation would be blank. In addition, the radio, CD, and sirius satellite would go out and be non-functioning. Everything to do with the center console would go out. The car is drivable, but could be a SAFETY concern if you needed to defrost the windshield, because you wouldn't be able to do it with the controls frozen. The dealer has ordered a replacement navigation unit, based upon my description of the problem. I am currently waiting for the unit to come in, however, to make matters worse, the problem is intermittent. For example, last week this occurred ever time I drove after 5-10 minutes, now there has not been a single problem for about 10 days. I am planning to still bring the car in as there are a few subtle problems (ie the volume of the voice instruction goes to the minimum level after I set it to the desired level). Any thoughts?

    This has been an issue that was addressed many months ago here. The dealer replaced my Navigation unit a while back for the same issues. It seemed to have corrected the problem. Every so often the computer would "Lock up" on boot up when starting the vehicle and nothing would work. Since the replacement unit was installed I have had the same incident happen once or twice, over the course of about 6 months. The only difference now is that after about 5 minutes the computer would clear itself and restart while driving. My dealer is aware of this ongoing issue and is in communication with Infinity Tech Support.
  • The dealership still cant tell me why exactly the tranny is being replaced. At first I was told that there was a small part on the tranny that was bad, specific part not given, and that infiniti wanted the whole thing replaced because of the such low miles on the car. Then I was told that the dealership actually talked them into it, "taking care of their customer." Anyways, I dropped it off on the 18th, its now the 26th, and they told me today that it will be at least the 16th before the tranny is here. Any idea how long it will take them to put the tranny in? That's dangerously close to the PA 30 consecutive days in shop lemon law, and yes the car is leased but PA lemon law covers leased vehicles. Oh yeah, they put me in an absolutley beat up '04 G35, I need BT and Nav so they just put me in a QX56... ugh!! Why cant they give me an M??
  • blov8rblov8r Posts: 567
    Lucky you're in PA .. some states specifically exclude leased cars from lemon laws. At 30 days, is it "automatic" that the lemon law kicks in? Or do you then have to go through a lengthy process to get the car replaced?

    In any event, why do you care why the tranny's being replaced? It's being replaced because it's got a problem and Infiniti is doing the right thing by replacing it. You can't make a "bad faith" argument, and they've accommodated you with a QX56 ... not my choice, but they're doing their best (IMO). Installing a new transmission is at most a half day affair IF they put their people on it right away. That it takes that long to GET a transmission isn't a surprise ... it likely has to come from Japan and is hardly the kind of thing they keep on the shelf. Bart
  • I would like to be able to disconnect the ICC cruise control, and only use a standard control. I do not like the brakes to be applied when I am passing a car on the left on a curve on a four lane road. I also do not like the distance to the car ahead before the ICC applies the brakes, even on the shortest standard setting. On occasion the ICC has applied the brakes by sensing something on the side of the road. If the ICC cannot be disconnected, can the sensing angle or the distance to the car ahead be altered?
  • blov8rblov8r Posts: 567
    In a word, "yes". It can be inactivated ... I don't have the manual in front of me right now. Bart
  • Bart,

    Thanks for your answer. Where can I get a manual that outlines the proceedure to deactivate the ICC, or can you advise me this proceedure when you locate your manual?

    Bob

    You didn't get a manual with your car?
  • nycdudenycdude Posts: 33
    On the 2006 M35, you can activate conventional cruise control (non-ICC) by holding the cruise on/off button on the steering wheel down for a few seconds when first engaging the system. This is set forth in the manual.

    I would like to be able to disconnect the ICC cruise control, and only use a standard control.

    Bart and nycdude are correct that the ICC on 2006 and later M35s can be disengaged. Unfortunately, I don't believe this is possible for the driver to do in the 2003 model.

    While talking to my Service Manager about the current ICC recall, we got into a discussion about previous year models. I was unaware, until that conversation, that previous implementations of ICC did not include "regular" cruise control as a backup to the "intelligent" version.
    Therefore, I think the only cruise control available to the driver of a 2003 M is the "intelligent" variety. I believe that complaints about the lack of cruise control during rainy conditions("intelligent" cruise is disabled when wipers are engaged) and fear of using "intelligent" cruise persuaded Infiniti to provide both versions on 2006 and later models.

    Your Service Manager should be able to confirm this for you though.

    For starters, hilley, there WAS no 2003 M35. They had the M45 which I personally felt was a better looking car (as I felt tha 2nd iteration of the Q45 was better looking than the 1st and 3rd efforts).
  • altaredaltared Posts: 12
    Am glad I did not purchase the Technology package in my '07 M35. I just didn't see any value in ICC, Navigation, tracking headlights, etc, etc. There is a point when technology is just 'too over the top' to be practical. I did buy the Entertainment package though. Have had no issues yet at all with my vehicle (but had it only a month so far).

    Like some others, I would have liked to seen a 6th gear or overdrive like my 2000 Infiniti did for touring/cruising, but that is a minor issue in my mind for a performance based vehicle.

    Several times I have pulled into a gas station and started to fill my gas tank, only to find that the pump turns off after just a few gallons..well before the gas tank is full. If I wait a little, I can pump more gas into the tank..but it can be two or three tries before I really fill the tank.

    I believe this is due to the gas tank vent somehow getting blocked when the gas is pumped too rapidly....not necessarily a problem with my specific car, but perhaps a design "feature" of the M35.

    Has anyone else had this problem?
  • blov8rblov8r Posts: 567
    Occasionally, but I've never had a car that has been immune to this "balking". It's clearly a venting issue and I tend to encounter it more in the summer months than winter.

    For the record, my gas mileage never got above 16.9 (per on board computer) for the first 10K miles ... now I'm getting 17.4 and we're still pumping the summer blend here. In addition, I've dropped from premium (91 octane) to middle grade (89 octane) and am still doing better.

    I use 87 octane in my 2006 M35 without difficulty.

    Note that octane rating has nothing to do with gas mileage. You will get the same mileage no matter what octane you use. You only need to use higher octane if the owners manual recommends it.
  • james27james27 Posts: 433
    In order to not burn holes in the pistons when using a lower octane, the computer changes the timing and the power output of the engine. Depending on how you drive, you might very well be tempted to push the throttle harder to get the same performance out of the car. If you do that, you will get lower gas mileage with the lower octane. It very much depends on how you drive.
  • Are the seat bottoms only heated, not the seatbacks, with the heated and cooled seats
  • blov8rblov8r Posts: 567
    I'm 19 months into my M35 Sport and still haven't had a moment's problem with it. Its endless array of high tech "stuff" wore off as novelties usually do and the only thing that still impresses me is the nav system. The Bluetooth phone capability is fine but frankly I find it no more useful than my OnStar in my Caddy ... and with my OnStar I didn't have to remember to carry a cell phone with me everywhere I went. Still love driving the car, but there's a lot of dollars tied up in things I can (and do) readily live without. Bart :shades:

    Has anyone experienced their M shaking or pulsating when they are cruising at roughly 37mph and 1400RPM on perfectly smooth road. My car has been doing this since the day I bought it, now I have 18000 miles and there still has been no resolution. Any ideas welcomed.
  • james27james27 Posts: 433
    Mine has a very slight pulse only when cold at around that speed. It seems to go away once warmed up.
