2004 INFINITI Q45 consumer reviews

The car is extremely quiet on highways but noisy over some small bumps because the tires are made for performance driving and are not quiet. I am switching to very quiet tires. It is a 2004 Q45 premium with 90 miles. I have only paid for normal wear and tear and the car has been problem free. It is fast - 0 to 60 around 5.5 to 6 seconds and corners like a sports car. I never have to switch the suspension to the performance mode.

The car is now exactly 2 decades old, registered in Jan 2003. I've had no engine repairs except the starter and a couple of hoses. I bought the car in 2015 with 65K miles on it and now, Feb. 2023, it's still only at just under 102,000 miles. (I'm retired; no need to commute in it). Mine is the Premium trim which means it has cooled seats, power trunk lid, power rear window shade, headlamp power adjustment and more. Someone complained about the harsh ride for a big car. I took care of that by switching from 18-in wheels to 17-in and asking the tire dealer for the softest-riding tires. My mileage remains the same, 24 mpg highway if you cruise at 70 mph. Mileage decreases by 1 mpg for every 5 mph increase in speed after 70. I abused the car in a very harsh winter once, and that's when the ball bearings and the front suspension went, and eventually (not related to winter abuse) I did have to replace the steering rack. All told, after 8 years and 37,000 miles of driving, I've had $10K in repairs. (Again, almost no engine repairs, and no transmission problems). That's $1250 a year average. But then, the car IS 20 years old, and there's nothing wrong with it now, and performance and comfort are great, and it actually looks and drives more like a 4-year-old car. Someone compared this to a Mercedes, but the Merc will crap out on you after 100,000 miles! A flagship Nissan won't.

Well made car and head of it's time with updated amenities. Good comfort inside for long trips and holds value well.

This is a very nice luxury car that is very comfortable. It comes with updated technology. The down fall is V8 engine and the premium gas intake. If you can afford it its worth having.

Nissan bills the Infinity as their luxury line. It is not even close to a Lexus or Mercedes. It has good performance, but that's where the positives end. The suspension is harsh and noisy and the car in general does not meet the comfort standards of the competition. I drive a Mercedes 500 S and the Infinity is not even close to the Mercedes when you compare the cars for comfort and safety. My son owns a Lexus which I have driven and the Infinity falls short again. The reliability of the Infinity has been horrible. I replaced both front bearings and the drive shaft at a cost of $2,400 before the car had 60K on it. The cruise control is a joke with the computer mounted below the front bumper where it is exposed to the elements. That fix cost $1,500! I can list numerous repairs in the $200-500 range. The car suffers from poor design and the use of cheap parts in building it. If reliability and cost of repairs is important to you steer clear of this brand. The Mercedes has never had parts fail like this and compared to the legendary reliability of the Lexus the Infinity is junk.

Top of the line luxury automobile with every possible option! Rides like a dream with absolute comfort.
