2002 Infiniti Q45 4dr Sedan (4.5L 8cyl 5A)


Review

This car was plagued by excessive oil consumption (1.5 to 2.0 quarts per 2500 mi.)after 8,000 miles with blue smoke coming out of exhaust during initial startup. Dealership was great and did what they could but Infinity claimed it was normal. After checking with other dealerships out of state and finding out they had to replace engines in other 2002 Q45s I requested a replacement. It took 12 months to finally get Infinity to replace the engine. They said they had to monitor the oil consumption over a period of 3 oil changes. The new engine doesn't burn a drop! Had to have the rotors turned down after 20,000 miles (warped) and had them replaced 7,000 miles later due to the same problem.


Favorite Features

The car rides well, is quiet and IMHO is better looking than the LS430,and has plenty of power. Although some people complain about the complexity of the voice recognition system I find it quite user friendly.


Suggested Improvements

The trunk capacity for a vehicle this size is inadequate. It just barely holds to sets of golf clubs. The clock is difficult to read in the center of the console.

2002 Infiniti Q45 4dr Sedan (4.5L 8cyl 5A)


Review

This is my 2nd Nissan cars and 1st Q. I have test drove both BMW 740 and Lexus LS430. Both are good cars, but my money went to Q45. This is the best car for the money. It has good handling, comfort, and reliability. This is a fast luxury sedan and you won't see lot of them in the road. I get compliments how sharp and nice the car looks. There's little bit of hesitaion during acceleration, but checked with Infinitihelp.com and downloaded the document plus the TSB number, took it back to the dealer and fixed the problem. I will keep mine for a long time and buy another.


Favorite Features

navigation, traction control, rear camera.


Suggested Improvements

Sportier suspension, slotted/cross drill rotors, bigger brakes and 20" wheels. I've read that 2006 Q45 now has sport model. It came with 19" wheels.

Review

This is the best car I've ever owned. By now, I'm usually bored with my vehicle and ready to replace. Almost 4 years later and I still love my car. I am the 3rd owner of my '02 Sport, I bought mine in August 2011 with 116K for $7K, a steal at the time. It now has 165K on the odometer and in those 50 thousand miles all I've had to fix was one wheel bearing (other than routine tires/brakes/plugs). That's fantastic. The routine maintenance is costlier than most cars but not wallet breaking. This is like a "Japanese BMW" that doesn't ride so stiff.


Favorite Features

PROS: nice looking, very comfortable, extremely roomy, amazing stereo, fantastic highway cruiser, ridiculously great at highway acceleration, sweet climate control system, voice controls, handles pretty good for a huge car, the gatling gun HID headlights are really nice.


Suggested Improvements

CONS: Radio/climate controls could be more intuitive. Trunk has 3 issues: it's a bit small (albeit to accommodate the sub, amp and rear window shade), the lid likes to close unexpectedly and the hinges are exposed to trunk area (must avoid filling in that space). Rear window shade tends to stick closed (just needs a small tug).

2002 Infiniti Q45 4dr Sedan (4.5L 8cyl 5A)


Review

Recently there was an update for this model Q45. Infiniti calls it the ITB-02048 update. And what a difference it made. No more hesitation on takeoff. The first part of the fix replaces the accelerator pedal with one with a bit less lag in the pedal itself. Nice update. Good update. The second part of the update doesn't involve any new parts - it is all ones and zeros, but it's what makes the big difference. It's gone from Oldsmobile shifting (no offense) to German shifting, and from a stop the car feels so much faster. It reprograms the Engine Control Module. Shifting and acceleration are totally different.


Favorite Features

The car shifts like the little G35 after the update.


Suggested Improvements

I would use cerramic brake pads. Seems to last longer and does not warp the disc.

Review

Car has now been flat-bedded for repairs 3 times, am on 4th battery ("Infiniti" batteries are made in Mexico and last me 1-2 years.), entire left side of exhaust--engine to tailpipe--had to be replaced, one entire HID assembly replaced at less than one year, all 4 pressure gauges needed replacement, body shop did poor work and failed to cover all new paint with clear-coat, console cup holder lid requires solid thump to open, glovebox- -with 6-disc changer--has very little room, paint scratches if you look at it cross-eyed, crazing developing in f/r bumper fasciae, transmission still hesitates too much on downshifts, cruise "On" light "assembly" burned out--over $300 (Skipped it.).


Favorite Features

Very comfortable interior still is, stereo is great--though integrated and cannot be modified, storage in rear center armrest is nice--but it always pops open, and that's it. Oh, it's only broken once this week--another dead battery. (Optima Red Top, here I come.)


Suggested Improvements

Build it with the quality that a plain old Nissan Maxima or Altima would have. Well, a moot point, since the Q is no longer with us. Hmmm...wonder why.
