  • I have a mint 1992 Q45 and the air bag light flashes on and off while I drive. This all started in May 05 after I had some work done with the fuel injector. The work was done by a garage other than the local Infiniti dealership. I was then told by that garage that I would have to take it into a Infiniti dealership for the computer to be reset. They want to charge me $108 to just evaluate the situation. Is this common on Q45's?

    Did you see my reply to you just above your most recent post? The reason I suggested that is because this is not one of our most active discussions and I was thinking that the folks hanging out in that Technical Questions discussion might have a thought for you while you wait to see if someone here can suggest something.

    Hope this helps.

    Why does Infiniti treat the Q so poorly? No ad support (I've seen the new mailing with not even a whisper of the Q), sales people treat the car like it has leprosy, and nobody I know of seems to care about this car or even know that it exists.

    The Q SEEMS like a fantastic car. Why does infiniti treat it like an unloved stepson? This car could and should be out on the leading edge of luxury automobiles. Why bother making a car that you have no plans to support?

    I just don't get it.

    Posterboy - I think your car has brake pad sensors (my 93 did). When the pads are worn the sensor detects this and pops a relay that triggers the warning msg. If you replace the pads before they're too worn the sensor never does this, so you don't know about the relay. But once the relay is broken it must be replaced to get rid of the warning light. I think the relay might be optional and your repair shop may not have ordered it with the brake pad kit, but I'm not sure about that part. In any case, I would expect this to be the cause of your warning light not being "reset"

  • I have the same exact problem in my 1996 Infinity Q45

    my son bought a used Q45 several months ago. a few days ago, all the dashboard lights ~ other than the one that warns of "brake pads worn" ~ are out... no light at all. i check the fuses and did not see one that said dashboard.. but looked them over anyway without any luck. anyone have any suggestions?

    also, although the brake lights and the turn signals work, the rear running lights do not work making night driving dangerous.

    the car has alot of miles and is not worth putting alot of $ into. would appreciate and thoughts or ideas.

    You might want to also post this in our Electrical Problems discussion. And have a look at the rest of the discussions on the Maintenance & Repair board in case something else there might be helpful to you.

    Good luck with it.
  • I have a 2004 Q45 with active suspension that I would like to lower by approximately 1". Eibach and intrax used to offer springs to lower this car but they have been discontinued. Does anyone know of any spring manufacturers who offer this package? Does anyone know of any concerns of lowering these cars which have active suspensions?

  • While I am not totally familiar with the 2004 Q45, I am 'a guru' on the real active suspension Q45a (90-95). The new system is more properly called 'active dampening' control. If you can adjust the ride height (driver control) there must be a means of 'adjusting' the 'normal' ride height up/down by repositioning the height sensors. Look in the FSM and study the system. I can provide general background and theory, but not specifics (yet) on you car. Gotta look it up.
  • I just read your post. I supply recharged active suspension accumulaotrs for your car--several hundred in service. Looks on NICO bulletin boads and search 'TexasOil' posts. Simply swappin gout (exchange basis only) your old flat accumulators with freshly recharged ones will restore factory new performance of this fantastic suspension system. Drop me a line at my email and I will send you several articles I've developed and some helpful hints, etc.

    I JUST FIXED MY 94 Q45 BY REPLACING THE MAF(MASS AIR FLOW SENSOR) THE ONLY INDICATION I HAD WAS TO TAP IT WITH A SCREW DRIVER AFTER IT WAS WARMED UP. DEALER WANTED $550 WRECKING YARD $300, GOT ONE ON EBAY FOR $80. VERY HAPPY WITH THE CAR.

    I am looking to buy a 2003 Q45 with the premium package... my q's:

    1. Is there any way to tell if the car has the premium package using the VIN number only? I know to look for the b-pillar vents, or the rear seat audio/a-c controls, but wondering if the VIN would do it, or is there another quick and easy way?

    2. What items should I look for when buying used? What came with the car when it was new? 2 keys, owner's manual, first aid kit, floormats, etc. If someone could give me a list, that would be great.

    Thanks in advance!
  • I am thinking of buying a 1997 Q45. It has 210,000 miles on it (including 62,000 in one year b/c of highway traveling for work). $4750 is the asking price. The owner is the only owner. I have also looked up the mechanical history from the dealership. The car has had all regular work done i.e. 40,000 tune-up, 80,000 tune-up, oil changes, etc. The owner babies his car, and is a friend of ours. Is it worth the price with the high mileage? How long can I expect the car to last?
  • I am thinking of purchasing a 1993 Q45. It has a little over 150,000 miles on it. The price is $1600. I am purchasing the vehicle from a gentleman who is an owner of a car lot. I am not sure of the upkeep or the amount of previous owners. I am purchasing this car from a friend of a friend who happens to own a car lot. What things should I look for or ask the gentleman selling me the Q45?
  • When is the current Q Series scheduled for an update / remake? Is it for the 2007 model year? Are there any spy shots or renderings floating around?
  • miata007miata007 Posts: 129
    To anyone who is buying a used Q, be sure to check with a dealer regarding to the actual service history of the car not from some partial paperwork from the owner. In addition, it is highly advisable to have that vehicle inspected by a certified mechanic or Infiniti dealer. Q is a reliable car but also very expensive when it comes to servicing.

    Here's a link that helps choosing an an older Q.

    1997 Q45 with 210k: You should pass on that deal. $4750 is a bit hi on this car with poor resale value. I would consider it for $3500 only if you are mechanically able.

    First thing to ask is "Has the timing guide been changed"? Does it have active suspension? (You don't want that)
    Be sure to get the service history and have the vehicle check out by experience mechanic.

  • I have reade many of the inquiries about TCS and Slip indicator light on at the same time that the car will not go more than 3,000RPM and will stall under constant acceleration. This is an indication that the car is in fail safe mode. If you look in the TCS Control unit, in the truck under the LH speaker, you will see a led indicator light flashing. Count the number of flashes and that is the code number.

    In my particular case it turned out to be code 19 which stands for TCS motor circuit and TCS actuator.

    However, even with this much information I still have not been able to fix it. The problem I having is that when I go through the problem solving process prescribed by the manual it specifies that ther should be no conductivity between terminal 5 of the TCS Relay connector and ground. In my case there is. The prescribed solution is to repair harness between terminal 5 and Fuse link box. I have checked the wire and there is no problem between the terminal and the fuse link box. In the fuse link box a fuse joins the Read and yellow wire from the fuse connecor with a White and blue wire that goes to other locations.

    Personally I do not see how conductivity can be avoided becsuase in the wiring diagram it appears as if the white and blue wire is grounded in some parts along its trayectory.

    Any suggestions? :sick:
  • I didn't notice if there was ever an answer back to the problem that this gentleman posted back in May of 05 but He had the exact same oil consumption problem with my 2002 Q45 at about 70k miles on it. It is using about 1qt per 1000 miles. I've read that it's loose rings?, any help would be great.
  • patpat Posts: 10,421
    Hi. Why don't you also post in our Got a Quick, Technical Question? discussion. Give all the details rather than refer to a previous post to make it easier for someone to help. Good luck.
  • Good Morning
    I have an 99 infiniti Q45t and lately have been noticing a problem when the car is idled. It seems there is some loss of power sort of a feeling like the car is running out of gas. I have done a fuel cleaning, but the problem persists. Has any one experience this, if so, can you let me know what you did to resolve the situation. Thanks.
  • patpat Posts: 10,421
    Hi yadivery, welcome. I suggest you also post this in our Idle or Stalling Problems discussion. There are more gearheads hanging out there than here. Good luck - I hope we can help.
  • hello all, I just perchased a used 2001 q45 with nav and the touring package. It has 87000 miles on it and is in very good condition mechanicly and cosmeticly. I paid 14k for it, that seems to be a good deal, am I correct? Also, it did not have the nav cd's, they are new around 120.00 per region, anyone have any cd's they want to sell?
  • patpat Posts: 10,421
    I hope you enjoy your new ride. To me, the Q45 seems to be a hidden jewel and I'm glad you found one that suits you. :)

    I just need to explain that you can't use our Forums for buying or selling anything. Have you tried eBay?

    And a tip for you - I don't know whether you got "a good deal" or not, but why worry about it? It's done, you've got the car, enjoy and have fun!
