Infiniti Q45



  • Let's see if I can remember the way I removed mine? Just kidding, I replaced a dash and a speedometer and know that you will not have to remove the whole dash. The first thing will be to remove the panel around the steering wheel, or the wood trim if you have that in your car. Then you will remove the plastic covering from around the steering wheel which will expose the steering column. Make sure that you put the steering wheel is all the way down so that you have room to remove the top panel. after all this is done you can see all that you need to see to fix your problem. I have done some major changes to my car and if I can help in any other way let me know and I hope this helps.
  • your cd changer needs to be reset. i have a '95 and i just need to take out the plugs for about a min then it resets and i can play cd's fine.
  • I purchasedt he car about 2 months ago and it worked like a charm in the beginning. About a week later it started stalling when i came to stop lights/signs or was in traffic. I had a diagnostics check on it and nothing turned up. I also had it checked several other times but no one could find the problem, I was basically told not to worry about it since it didn't show on the computer and it didn't ahppen when they test drove it. I'm a little concerned because I can't seem to find out what the problem is. Before it looses power it usually starts to shake, alot of exhaust comes out the tailpipe and the rpm gague goes from 0 or 1 to 2 then back down and vice versa. Once it looses power and cuts off, it starts back up. The problem doesn't happen all the time it can happen for a week then the next 2 weeks no problems at all. Has anyone else had this problem? Please contact me if you can help with this problem. Other than this issue the car is wonderful.
  • I just had the same problem.Started up fine on a cold start took off and engine died. Pulled over and engine cranked up but felt like running on half power for a few seconds then died. Next two attempts to start no luck at all.Next try maybe 2-4 minutes after the initial problem it started up and is running fine!
    Hopefully it is justa dirty fuel filter but so far I can't find it to check it.
    The fuel tank was full and I dont often let the tank get to low so as to keep the fuel pump cool.

    The only other quirk on my 94 Q-45 is maybe once a month or so the transmission will rev high in a low gear without shifting up.It goes away after a minute or so and runs normal again.
    I really like the cornering with the active susspension but the ride is very rough- the rear passengers complain!
    Other than being a gas hog it is really fun to drive!
  • Yes, i am facing the same problem. Its a 1995 Q45. it has 161k miles on it. It stops at the red signals at the intersections or at the stop signs. I have to put it in parking mode and then stop it and start it again. Then it runs again. I dont know what the problem is. Hope its not the transmission. Sometimes when i go on the freeway when i press the gas pedal it does not accelerate, the speedometer starts going down. Then after a few seconds it runs. I am not sure what is going on.
    Please let me know if anybody knows what the problem is and how to rectify it.
  • You guys might want to check out the MAF (Mass Airflow Flow sensor) to see if that's the cause of the problem. I would first check the wire connector and clean the MAF. If you need help here is a link:

  • I have a 96 Q45 that has a Sony 10 disc cd changer mounted from the factory in the trunk. When I bought the car, I did not realize that the magazine assembly (holds the cd's) was missing. Sony says that they do not have it since it was made for Nissan (Infiniti) and that I would have to order it from them. I tried that but my dealer is saying that it has been "discontinued". I have also tried several electronics dealers too with no luck. Other than replacing the changer, does anyone have any suggestions? Thanks!

    I received a red "A Line Has Been Drawn" brochure from Infinity a few weeks ago displaying their current line up, with an artistic brush stroke defining the look of each car. It lists and waxes poetically about (in this order):

    G35 Sedan
    G35 Coupe

    No mention of the Q45, though. Interesting.
  • 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?

    I also recently noticed that the screen on my dashboard was alerting me that my "Brake Pads Are Worn". I took the car in to have the pads replaced, but the same message has remained on the screen? When the car alerted me of the rear pads being worn last spring, I had them replaced and the message discontinued. This time I don't have a clue. Can someone please help?

    Yes, there's a reason for that. I was very interested in a Q this fall, and when I went to the dealer to check them out, they only had 4 of them, I asked to drive one, but the salesman kept trying to interest me in the M. I have not interest in the M. The Salesman finally agreed to give me a price on the Q, but in his efforts to move me to the M, he told me they didn't think the Q was going to be continued for 06. Perhaps it hasn't. His classic line, when I told him I was interested in the Q was, "Oh, we don't sell many of those"...... I can see why. They didn't sell me one either, the deal was horrible. I bought a Lexus LS430 instead.

    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
    Did you ever fix the problem by cleaning the corrosion up on the power steering module????

    Let me know before i rip the dash apart.
    P.S i have 176,000 on my bad boy best used car i ever bought

    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?
