Overview & Reviews

For 2005, Infiniti's flagship sedan receives updated exterior styling with new front and rear fascias, a new hood, headlights with integrated foglamps, a new trunk deck lid, LED taillights and fine-line chrome trim. Instead of offering Luxury and Premium models this year, Infiniti will sell a base Q45 (with all the Luxury equipment) with an optional Premium Package. Inside, the Q45 features new "sport contour," double-stitched seats and a new instrument cluster, along with a metal-trimmed shifter bezel, metal knobs and dark maple wood and chrome accents. The transmission has been recalibrated for better response, and the performance-tuned active dampening suspension, previously available only at the Premium level, is now standard on all models. Base models get a new 17-inch alloy wheel design this year. Other enhancements include standard rain- and speed-sensing wipers, a revised DVD-based navigation system (also standard), and new brake-operated "pre-crash" front seatbelts, which tighten under emergency braking.

• Elegant and spacious interior, long list of standard luxury features, strong V8, excellent value.

• Unnecessarily complex interior controls, small trunk capacity, not as athletic as some competitors.

  I Love It, I Really Do - 2005 Infiniti Q45
  By Q45 - December 28 - 1:53 am

  This car is a dream to have. I waited a lot of year to purchase one because of its pricing. It handles well and is a pleasurable driving experience. It is Classic but yet Sporty and I like that!

  Have owned a caddy, and Lexus, gm and Chrysler, Ford cars. Nothing like a Q45. What a beauty! Love it and strongly recommend as a preowned. Excellent value.

  great but I wish it was prettier - 2005 Infiniti Q45
  By Joe Scheideler - July 24 - 11:10 am

  My beautiful 93 Jag was totaled, so I test drove the Lexus, BMW, VW Phaeton, and for handling, power (340 hp), good visibility, comfort, and relatively easy to control gadgets this seemed to be best. Great turning ratio, terrific techtonic tranny, sports mode, slip differential mode, fab radio, cd and sirius satellite, bose speakers, heat and air seats, and the navigational map system; voice controlled. My old jag was prettier but this babys got it all.

  No Title - 2005 Infiniti Q45
  By Don Newton - November 28 - 12:06 pm

  This vehicle is prety much everything I expected. The back-up TV could be brighter and I would like a brightness control on the navagation map. I would also like the option to NOT go to the nighttime map display when the lights come on. Standard daytime running lights would be nice too. NISSAN needs to dump those d--n low profile tires. While they improve handeling: they are ugly, transmit road noise, and ride rough as h-ll!! Thats prettty much it for me.

  Ridiculous value for such a luxurious car - 2005 Infiniti Q45
  By sullivan86 - October 13 - 1:34 am

  I was looking for an every day car for myself after my previous car, a 2000 Dodge Neon finally died. The Neon was my first new car purchase and served me well through the years, but being 12 years older and more successful, I wanted to get something nice to drive that wasnt going to cost an arm and a leg. I searched Craigslist for about a month in the hopes of finding a deal and low and behold, I find this beauty. I honestly thought the $15k price listing was a type-o until I did some research and saw how much these cars depreciated in value. No matter. After viewing/driving the car I felt like I was getting away with robbery.

  My third Infiniti - 2005 Infiniti Q45

  And they just keep getting better. I love this car. It has a luxurious interior that is matched with a beautiful performance. The car comes loaded and is worth every penny.

  Exceptional Car, Poor Selling Policies - 2005 Infiniti Q45
  By HRM - August 30 - 4:06 am

  Having driven luxury cars for the past 12 years, I was pleased to purchase the Q45. It is everything that I thought it would be and more. The only disappointment is the lack of an "Onstar" like commmunications device like similar cars. My biggest disappointment is the lack of advertising committed to the Infiniti line. Mercedes, Lexus and Acura devote more time and monies to advertising their luxury cars, which in my opinion do not even come close to the value for dollar of the Q45

  2005 Infiniti Q45 (A pretty good car) - 2005 Infiniti Q45
  By G - March 2 - 8:26 am

  Has a very solid feel, if you need HP to get up and go, no problem, lots of power, lots of interior toys (a bit cumbersome at first to use). I personally do a bit of hgwy driving and this is a pretty good car to be in. (Great cruise control feature)

  Great find - 2005 Infiniti Q45
  By Joe - January 29 - 2:00 am

  I searched months for the right new car and found it in the 2005 Infiniti Q45. It is powerful, quiet, smooth, comfortable and reliable. Most important I am as pleased today as I was when I first made the purchase.
