I have had this car for 2 years and been extremely happy with everything! Except, lately I have a reving when I start the car or when stopping at a light and continuing at a slow speed - and the excelleration does not increase. I was told by my independent certified repairman that this is an indication of transmission trouble. Is there anything I can do short of replacing the trannie or junking it? Finish is perfect, interior is great and it rides like a dream - hate to give it up, but hope I don't face a complete transmission replacement. Help Please.

Has the filter and fluid ever been changed?
If it is going out it comes down to one question. Is it Beyond Economical Repair?

Thank you so much for the quick response. I had all the hoses and belts replaced in April (it is an Arizona car and I wanted them done as a precaution). I believe the mechanic said at that time that the transmission fluid looked good - not sure about the filter. I will check on both again.

#20 of 26 03 Q45 Radar Cruise Control by cobrapc

Oct 15, 2009 (5:37 am)

I recently purchased my 03 Q45 that has the radar cruise control. It seems to be acting weird, and I need to know if this is normal. When I go under a bridge, (sometimes,) or if it stays in the zone where it's picking something up for several seconds, it will beep and stop the cruise like you hit the brake. Problem is it will not resume or let me reset the speed until I have shut the car off for a few minutes. Sometimes it won't start cruise at all.
Can the radar function be disabled? It's a true pain.
 
I hope I didn't make a huge mistake buying an Infiniti.

I own an '02 Q-45 and have seen M-45 driving about, and wondered when each was
made.

#22 of 26 clunk noise in reverse by turbojoe25

Feb 20, 2011 (8:01 pm)

i have a 2002 q45 with 127k on it. there is a clunk noise that it does from both front wheels when in reverse and turning the wheel 100% in either direction. i replaced the front struts and springs but no luck. wheels arent rubbing on anything either. noise is really annoying too. also if taking a corner sharp it makes the noise too. could this be a ball joint or something? i have no idea. rides perfectly otherwise. just the noise.

#24 of 26 2002 infinity q45 problem by bdb1029

Aug 26, 2011 (6:22 pm)

I have a 2002 infinity q45 which has been a wonderfull car for a long time, it has 112k miles on it and i am experiencing my first problem. Now i am no mechanic, but at first the sound appeared to be a power steering type noise that i've heard before, however the whining noise only happens on acceleration and continues through all gears. It does not affect the steering of the car at all and the car shifts fine as well. Im thinking this may be a transmission problem but the tranny seems to be operating fine. Also the other day i checked it both by turning off and on the ac, thinking it may be a pully and although it did stop for a minute it did then continue, so this may have been completely by chance. Has anyone got any ideas before i go spend a ton of money diagnosing possible non problems. Overall driveability of the vehcile is great and doesnt seem to be affected at all, other than this noise.
any help is greatly appreciated thanks.

#26 of 26 CHECK ENGINE LIGHT by njoyn1

Dec 31, 2011 (4:00 pm)

This problem concerns my 2005 Q45. I have almost 64,000 miles on this engine.
At times when I first crank the engine, the engine misses noticeably and the tach needle will fluctuate up to approximately 1500 RPM for a minute or so. Today I notice that the check engine light came on and remained on until the engine was switched off. The light did not come back on when I restarted the engine. I have not noticed any other problems.
 
Any suggestions before I make appointment with the servicing dealer?
