I love my 1997 q45!

Vehicle: 1997 Infiniti Q45

I have owned my 1997 Q45 for a year now. I bought it, one owner, from a meticulous person who took awesome care of it and it was garage kept. It's the pearl color with beige leather interior. I have tinted glass and 156,000 miles on it. Other then normal maintenance wear and tear, there have been no problems with this car. It's powerful, fun to drive and I get looks at every corner. I LOVE this car. I drive it locally around my town, but it could easily make it across country if I wanted. My car has near mint paint and interior is flawless. I keep the car in pristine condition and have maintained it with an obsessive mindset.

The best car i have

I've owned this 1997 Q45t for over 10 years and except for normal wear items, tires, brakes, etc. it has not cost me a think to maintain. I just had it at the Dealership to have one of the Exhaust System shields removed because it had come loose, no charge and the service manager said they had customers with the 1997 Q45 with 300,000 miles on them. I have 130,000 and it still drives like new. My other cars for 40 years have always been Corvettes, but I enjoy driving my Q45t. When I bring my Q45t in for service I always get a free loaner, a new G37 which is also fun to drive, but I'm always happy to get my Q back.

Ignition coil problem or not?

Have driven my Q45 for 6 years without any problems. Last January, it started misfiring while idling in gear. I have had it to 3 different shops and replaced plugs with iridium plugs and a couple of ignition coils #4 & 2. I am still having the same problem after all of this work.

Hope this helps with those questioning Infiniti Q45 reliability. I have owned this for 8+yrs now, the odometer reads 170K miles. The only parts needed replacement were alternator ($300) and an ABS relay ($25). All else are running flawlessly and my mileage is between 18-21 mpg (within specs). Can't be happier - I hope I can run this for another 5+yrs. Maintenance is simple: Flush all fluids (AT, PS, brake, differential, coolant) every 2 years - doesn't matter mileage or usage. Your vehicle will remain gold. No need to do 30k/60k etc, which are primarily inspection-only.

Simply fantastic

I purchased this outstanding vehicle nearly a year ago and have enjoyed quiet, trouble free, luxurious motoring ever since.The car is great on long trips up to see mom-a 5 hour drive-not a problem in the Q. Set the cruise control and pack your cd's for the premium Bose stereo and your off! The powertrain of the Q is incredibly smooth,quiet and efficient. I've driven my dad's S-class Mercedes and detect no discernable difference. The Q actually handles very well for a large sedan also. The best part of the deal was the price-I purchased my black 97' in pristine condition for 9500$! Unfortunately, I wasted money on the 4- year extended warranty-not necessary,but I was terrified after owning a caddy sts.

Infiniti q45---the best!!!

The name "Infiniti" says it all: they last forever and hold up for infinity! This is the best pre-owned car I have ever had over the past 40 years. It looks & drives like a new car with many advanced(for 1997) luxury features that make it a pleasure to drive on long and short trips. These are "stealth" sports cars designed to look like pure luxury cars...it gets down the road fast and handles like a sports cars while maintaining the look and feel of a luxury sedan...I love my Q45 and suggest that everyone try one of these fine cars, that is, if you can find one, they're scarce & their owners seem to hold onto them forever---which I can now understand!
