Vehicle overview
As the second-generation Q45 enters its third year of production, Infiniti hopes that new exterior and interior appointments will help keep the vehicle flying high in the luxury performance sedan class. To that end, Infiniti continues its quest for enhanced comfort and convenience rather than building on the sporting nature of the original Q45. The sedan now offers a quiet, isolated ride worthy of dignified heads of state.
Just as one would expect inside a flagship sedan from a luxury marque, the Q overflows with sumptuous features such as power leather seats, wood accents, premium Bose sound system, driver's seat memory, automatic climate control, power sunroof and power tilt/telescoping steering wheel. This year, Infiniti also proves that it knows how to listen to its customers. The beautiful analog timepiece that adorned the dashboard of the first-generation Q45, and was replaced by a digital clock two years ago, is back. Additionally, the Q's full metal sunroof has been replaced with a power glass sunroof with tilt/slide, one-touch open and a sunshade.
Outside, Infiniti has touched up the styling of the vehicle by reducing the amount of chrome on the front grille, adding new high intensity discharge (HID) headlamps with Xenon gas bulbs and crystalline lenses, and introducing two round projector beam bulbs per side. The license plate finisher is now body-colored, the trunk has a power closure assist, and the outside mirrors have an anti-glare coating. New exterior colors for 1999 are Hunter Green, Aspen White Pearl and Titanium.
The 4.1-liter V8 engine is still in place, though some would be happy to see Infiniti bring back the 4.5-liter V8 that powered the sedan prior to 1997. Overall, though, the Q45 offers a nice ride that is perfect for cross-country cruising. If you are in the market for a large luxurious sedan, and are unwilling to fight the gremlins that habitually inhabit many competing luxo-cruisers, you owe it to yourself to test drive a Q45.
Cost to DriveCost to drive estimates for the 1999 INFINITI Q45 4dr Sedan and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of $2.83 per gallon for regular unleaded in Missouri.

1998 INFINITI Q45 4dr Sedan
I bought my Q45 10 years ago and it now has 188,000 miles on it. I am amazed at the reliability of this vehicle. It is far and away the best car I've ever owned. It still runs perfectly- like new today. I keep waiting for something major to go wrong so I can justify trading it in but it continues to run and operate perfectly. It handles well, is very comfortable, powerful and quiet. The … only item that ever failed was the alternator at 125,000 miles. I just need to tell the world that this car is the UNBELIEVABLY reliable. I am finally considering trading it in only because I've had it for 10 years and I want something different. I'm sure I'll be disappointed with it's replacement. Its a 10!
Awesome Car! Real Sleeper!!

1998 INFINITI Q45 4dr Sedan
Loved this car from the first time I got behind the wheel! Only paid $2500 three years ago (122K miles). Just turned over 167K....power steering pump, alternator, and two ignition coils have been the only replacements/repairs over those 45000 miles. Very sweet ride!

1998 INFINITI Q45 4dr Sedan
Just had to retire my 1998 Q45 due to being rearended and totalled.
Car had 232000 on it and was overall very reliable.
Not a single problem until 155,000 Miles.
Fuel Injectors, Coils, and just age were starting to cause more problems, but I think it would have gone to 300,000 if not for accident.
Overall, fun to drive, reliable, and excellent value as cost to own is only a little … expensive with gas costs.
But it proved to be safe as I hardly felt the hit from behind and he was going about 35 miles an hour.
I am sure it has been recycled by now!
There's not a better car I've owned...

1998 INFINITI Q45 Touring 4dr Sedan
Bought a 98' for cheap at 72K. Needed a bit, but after valve cover gaskets, belts, battery, oil, air filter, it was ready to go. It sat for years under previous ownership. When I purchased, it had the original belts on it still. A testament to Nissan/Infiniti build quality. It doesn't do bad MPG-wise either. It goes when you need it to. Despite the size, it goes around corners, and stops … quickly if need be. And it is comfortable! Expect 19 for city driving. A mix, you'll get 22 if you drive easily. Highway, right around 24 for me; way higher than the EPA estimate. For the money, you could get a Lexus LS400, but it looks worse, and it just isn't as nice. (I have a buddy who has one.)
We have a limited number of reviews for the 1999 INFINITI Q45, so we've included reviews for other years of the Q45 since its last redesign.
