Review of the 2005 Infiniti Q45

  • Fast, luxurious and priced thousands of dollars less than most peers, the Q is a solid buy for comfort seekers on a budget. But if owning the best is what matters to you, drive the competition first.

  • Safety
  • Pros

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

  • Cons

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

  • What's New for 2005

    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.

What a great car for any amount of money, but even more so when the prices are so low. Very fast, and luxurious. If you are looking to buy, I'd recommend finding one with the premium package as it adds a lot of goodies. On the description above it did not let me select Premium but only "base". Premium adds air conditioned front seats and many cool things for rear seat passengers like electric reclining seats and radio and AC controls.

Ridiculous value for such a

Vehicle: 2005 Infiniti Q45 4dr Sedan (4.5L 8cyl 5A)

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 wasn't 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.




Great find

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.

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.

Vehicle: 2005 Infiniti Q45 4dr Sedan (4.5L 8cyl 5A)

I drive 2005 Infiniti Q45 while my wife drives 2005 Lexus ES330 (got the Lexus first). Falling love with the Lexus right away, which does everything best. I thought the Lexus has finest steeling ever. Well, after the Q45, there is no way for me to trade with my wife’s Lexus, the smoothest steeling ever! Solid and heavy. very firm handling. don't feel 4000 lbs at all when I curve the car around. Manual mode (5 speed clutch-less) shift is so fun! Know how 340 hp can do, use the manual mode and 3rd gear,step on the gas! Now I know what is a difference between $40K and $60K cars! I am so spoiled by the Q45, I afraid I will have a hard time to think of other car.




Loss of value

Vehicle: 2005 Infiniti Q45 4dr Sedan (4.5L 8cyl 5A)

This is a great car, but I would recommend that all buyers interested in Infinitis first look at the tradein values before buying. My Q45 was $64K when purchased and is now valued at less than $30K! Infinitis, for some reason, sink like rocks. No matter the condition, mileage, etc, they lose value much faster than their competitors. Check Edmunds and Blue Book before buying... Caveat Emptor!

My 2003 Q45 makes a loud droning noise caused by some kind of vibration between 1,800 and 2,100 rpm, and has the same sound in any of the five gears, so it is not road speed related. My dealer has rep...
