Infiniti Q45 Maintenance and Repair

    I own the 2005 Q45 with 40,000 miles. My last request for assistance or advice concerned the airbag warning light. This problem was corrected by dealer under a factory recall. My auto ran fine for approx. 150 miles on my way home from the dealership.
    Three days later I attempted to start engine but there was no power. The steering wheel is "locked" as the key will not switch on. I have turned steering wheel slightly right or left and tried to switch key to on but this does not help. Interior lights do not come on when door is opened and I cannot lock or unlock vehicle. I have not had time to checked battery connections but the battery is less than 2 yrs old. Any suggestions or recommendations?

  • I experienced this very thing with my Q-45. Although my model is somewhat older the same remedy may apply. What I needed to do to unlock the car's engine was to put the key into the door lock and turn it to the left and then to the right. Seems in my car's mechenism there is a forced entry device that shuts the engine down when it thinks the car is being brokened into.

    It worked on my car, not sure about yours but what do you have to lose by trying?

    Much success with your Q-45, I am trying to get rid of mine now. Too many issues.

  • We have a 1994 Q45 and we need to know the adjustments for the tps and for the map sencor, and the mass flow air intake. It runs ruff and it wont pull itself. What do you do to get the codes to read over the dash. Thank you
  • I bought a new 2002 and have had no issues. I am selling it and seeking another
    with lower miles. When I test drove the potentail new one, the Supplemental Airbag
    Warning came on the screen upon starting. Any idea what this is and cost to fix ?

    I had a similar problem and was told that a momentary loss of electrical power causes the warning light to come on (and stay on) until reset. - My problem was solved when I replaced the starter that had a flat spot on the armature.

    To reset the warning light perform the following:
    *Turn the key on and as soon as the air bag warning light goes out turn the ignition key off. - Be sure to turn it off before the light starts blinking.

    Do that three time and when you turn the ignition on for the 4th time leave the ignition on and the light should go out. - It worked for me, but the permanent fix was the starter replacement in my case. Good Luck.

    I own the 2005 Q45 with 40,000 miles and I appreciate the suggestion I received on this site to correct the continuous blinking of the Air Bag warning light. I tried the suggested "fix" in effort to correct the problem. The dealer suggested I bring my auto in for diagnosis. The problem was corrected under factory recall at no charge to me.
  • Thank you. I am speaking of the light in the secreen area. It seems to come
    with engine starting. It is not the idiot light in the dash area. Is this what you meant in post #276 ? Car Fax shows no issues with this car for accidents nor
    are there any signs of any accident in the front of the car i.e. over spray,
    fender gaps, etc. Thank you.

    I have a 1992 Q-45 Infiniti. When I drive over bumps, my car sways to the right. Does anybody know the name of the part that would fix it? I was told that there is a cover for the wheel bearings. I need to know the name of the part. Thanks
  • Stopped by my local repair shop to see about getting a trans fluid exchange done on
    an '02 Q45. They asked me if it had a dipstick for the trans, I said no and they did not
    want to do it because they could not measure fluid even though it is in with the new and out with the old. Anyone else experience this? I am not looking forward to going to
    the dealer and may not need to.

    I replaced my rotors, pads, calipers and bleed the brakes, but for some reason unknown to me the rear brakes will not catch. The car is 1994 Q45. Any suggestion?

    I have a 94 Q45 my ABS light and brake pads worn message will not clear even after replacing calipers, rotors and pads. Neither will the rear brakes catch.

    I had a 94 Q45t and had a similar problem re not starting when everything else worked. - I replaced the starter relays. - There are two relays and are mounted on the firewall on the passenger side. I believe one of the relays is for the primary starter circuit and the second one is for the ignition circuit. - Your Infiniti dealer should have them either in stock or be able to readily order for you. - Good luck.

  • Great site..I'm on my 4th Q 45 and love them !!
    91 4 door gas 285 Hp 65,000 miles :)
    I am trying to remove my Alternator and so far can;t get it out after four hours.
    I have: Removed plastic cover-Alt Belt-Outside bracket..I guess I need to remove the inside (on Block) bracket but I have stopped because I want to make sure i'm not in over my head. Does anyone have a pic of the bracket and it's mounting points or can you guide me to what is next to remove..
    IE entire idler pulley-fan-a/c compressor etc!!
    Also I can't even find the wiring that I know has to be connected..this is a very tight area not to mention the most difficult alternator I have attacked! :mad:

    Hi Cobrapc,

    I'm having the same issue with my 02 Q45. Screen went dark while heat and stereo was working. I re-started the car and now only heat is working - no more stereo. Can you please tell me what did you end up doing to fix the issue?

    Thanks in advance.
