1991 Infiniti Q45 from North America


Incredibly awesome


HVAC display failed - the controls all work perfectly, it just doesn't light up and display current settings.

The transmission failed around ten years ago, but the replacement has worked flawlessly since then.

General Comments:

Very nice acceleration.

Excellent handling.

Extremely smooth ride.

I would feel perfectly comfortable driving down the interstate at 150mph, if that were legal.

I suspect the seats were personally designed by god.

The gas mileage isn't good (I usually get about 17/22 city/highway) but it's worth it, considering its comfort and performance.

This car's design was ahead of its time. People are usually surprised to hear how old it is.

Great car with style and performance!


Alternator went bad at 190,000, very expensive fix.

Brake pads wear about every 5,000 miles.

I just put a new rear differential in because of a leak at the rear seal.

New struts.

Both inner and outer tie rod ends, along with ball joints in the front.

The hood bends at the hood strut mounting location. Still needs hood.

The car seems to be having some rust problems at both rocker panels, also at both of the rear wheel wells.

The climate control display went out.

Now my A/C comp. is knocking.

General Comments:

The car,to me, is very comfortable. The seats are a little hard, but still you sink right in to them. There is plenty of room in side for passengers.

It has Awesome acceleration! After about 40 mph is when it really gets going. The Infiniti has massive power for a car of its size, and seems to keep going well after 100 mph. I had it up to 157mph and it was still pushing on. You are able to pass lots of other cars on the road with ease!

There could of been more cup holders, considering that there isn't a single one! I found a cup holder called the wedge. It seems to do just fine and fits right between the front passenger seat and center compartment.

On dry pavement the Q45 does just fine, but be careful in rain, snow, or ice. The tires will spin with out warning. That's why it has traction control right?

Other than the tires spinning the car handles great! It surprised me with it's ability to corner so well at higher speeds because of its size. The Infiniti is a wonderful cruiser, and floats like it's on air.

Over all it is a car that should not be beat, and well maintained, and you will be a lot more pleased with The car.

I'd say it is worth the money to have a car of it's class, style, and performance!

Best car I've ever owned


Replaced entire steering system-but probably due to leaking hose and subsequent damage to system.

Front squeaks badly, front tires have severe negative camber-tire dealer cannot tell me why, and car handles like a sports car, rides like a dream, behaves perfectly.

General Comments:

Too sudden/harsh downshift into first (car starts in second) and some smoking at high rpms, full throttle. However, I consider it my Japanese 4-door Mustang. It is lots of fun to drive quickly, handles well and got it for a miraculous price-$850! Thank you Jesus- it was a wonderful Christmas present for my wife last year. And I even get to drive it occasionally.

Great cat for the money


1. Fuel Pump

2. Water pump leaks

3. Climate control button

4. Valve Cover Gaskets

5. New Steering system

6.Lots of little oil leaks.

General Comments:

This is a great car, it is well built, and is still rock solid after 14 years. If you are looking at buying an Infiniti Q45, then make sure you have it mechanically checked out before buying. We have replaced, the whole steering unit, the valve cover gaskets, and the button for the climate control, belts, and Fuel pump. A suggestion to all of the owners, have a transmission cooler put in, this makes the transmissions last longer, because the Q45's transmissions are not cooled as well as they should be, this will also cause it to shift smoother. When you get one, you should have the fuel system updated with a new fuel pump, if it hasn't already been replaced. If the fuel pump goes bad, then the pump computer will burn up and cause it to go bad to. The fuel pump costs $300 and the computer costs $500. You should also have a tune up done, makes it run like a champ. This car is fun to drive; really I have the active suspension, which I really don't recommend, because it is not worth the money to fix.

I also have a 1991 Q45a and want to sell it. It's in perfect condition, 10,000 miles. It looks and runs (and smells) brand new! The problem I am having is trying to find out how much it's worth. It was over $45,000 brand new, and I have been on every website I could find (Kelley included) but can't even get the category for 1991 Q45a to come up - all I get is Q45, and at that, the top price is around $7,000, which seems ridiculous for this car. Any ideas? Thanks.
