What a ride! - 2003 Infiniti M45
By wslowry - November 5 - 2:00 amThe acceleration in this car reminds me of a 1968 Road Runner I had in my twenties except this car corners. I traded in a BMW 740I and in some ways this is a step down but in many ways it is an improvement. The A/C in the seat is great for the climate here in Florida. The warranty is 4/60 bumper to bumper and 6/70 drivetrain with lifetime free road assistance - hard to beat. The styling may not be your cup of tea but I can tell you it is an impressive vehicle to see in person - its obviously a car of substance. The extra 50 horses over the 5 and 7 series bimmers is going to come in handy I suspect. Gas mileage is a little scary though.

Great Car / Little Annoyances - 2003 Infiniti M45
By DC - July 31 - 12:13 amI bought this car used, Have had it one year now and love the car. Its a great car, but has these little annoyances that frustrate me to death. 1. Oil consumption. Have never owned a car that I have to put so much oil in (50,000 miles on it). 2. Glove box droops down, very annoying. 3. Trunk never opens enough so that auto shut doesnt catch it and close it again. What a pain!

Vive La Differance - 2003 Infiniti M45
By rick fish - July 14 - 2:00 amVery easy to drive at a high pace. Nose is UUUgly. Like (no, love) the rest!! Just bought one for my wife at $2500 under invoice and 1.9%, cant beat that with a stick. MY wife is no lead foot but the 3x Ive been on the highway with her shes cruising in the 80s and quite unawares.Fit and finish impeccable. Interior materials equal or better the competitors(excepting Lexus)

Preety Good - 2003 Infiniti M45
By robertem1 - December 19 - 10:00 amIve had my M45 4 months, and 5K miles. I took a long trip out west with it and got to work it hard. I got excellent mileage (23-24) at highway speeds. I love the power and can almost get the numbers that the magazines do. It handles very well at triple-digit speeds and is smooth and quiet. I experienced a problem with the tire pressure monitor, but once reset, it worked just fine. The interior looks very classy and elegant. The only things that I dont like are the transmission shifting and lack of bass in the stereo. It is just a shade short on headroom too. I will live with that for the $18 K under the Cadillac I WAS going to get.

Good fast car. Always in front. - 2003 Infiniti M45
By Jack Orr - October 31 - 10:00 amThe car is not as well packaged as the A6-there is less knee room in back and a very skimpy trunk. But, I found the reason for this is that the fuel tank is located between the back seat and the trunk. The safety benefit of this is obvious. The body is not what I would call a leading edge design. The paint job is excellent, everything fits, the doors close well. Fit and finish is top rate. Suspension is very good. Steering quite up to the task. The most outstanding feature, by far, is the engine. Oh, a last thought. The body is very rigid. No groans or squeaks. And it promises to be very reliable.

M for Muscle 4.5 V8 - 2003 Infiniti M45
By TJ - September 21 - 7:56 pmI bought a used 2003 M45 in 2006 with 28000 miles on it. It is black with brushed aluminum wheels. It also has hand painted silver and gray pinstripe along the length of the vehicle. This picks up the chrome and the wheels nicely. This car is a beast on the road. I have complete confidence in the capabilities when highway driving. The car is very stable. Stays flat on the road. No pitch or yaw issues for a car of this size. There is more than enough power to get you in/out of trouble ;)... The V8 is smooth and responsive. It responds with a growl during acceleration at any rpms. There is no equal for the money. What a value!

unsafe to drive at certain speeds - 2003 Infiniti M45
By candidph - May 7 - 2:00 amUnsafe factors are that the vehicle hesitates two to three seconds when sudden acceleration is required such as for merging lanes in freeway traffic. The cruise-control "collision avoidance" feature tends to cause rear- end collisions because it causes the vehicle to suddenly decellerate when it tries to pass a truck-trailer rig on an adjacent freeway lane, especially on an inside curve. There is a severe blind spot at the left and right windshield post and adjacent car door (where the rear-view mirrors are mounted) for people of short stature like myself, a problem for close manuvering.

My 2003 M45 - 2003 Infiniti M45
By PREFECTO - January 18 - 6:56 amI have 22k miles and see puffs of blue smoke on almost every startup. Have scheduled car to have an oil consumption test performed by Dealer. I know the car is using at least a quart of oil every 1000 miles. Dealer has already de-carbonated the engine! To NO satisfaction the blue smoke still appears on EVERY start. They tell me its the advanced oiling system providing more oil in the valvetrain area and just burnoff. Ive Called Infiniti direct, regarding breaking problems. Rotors warped, had to be replaced! Car was only two months old and had to have a new battery! I have spoken to Infiniti Consumer Affairs on three different occassions, which in my case, it has worked!

Rot Lot Causes Too Many Tow Ins! - 2003 Infiniti M45
By FirstTimeInfiniti - January 11 - 7:26 amI got a really great deal on a left over 2003 M45 demo with 1200 miles. The dealer advertised $10,000 off MSRP and thats what I paid. $35K for a rwd V-8 is a great deal. But with the deal has come some real reliability issues including new tires (Michelin Pilots) due to lot rot, new battery and a new fuel pump (all replaced under warranty). Ive had this car towed in twice in 6 weeks! I worked for GM for 4 years and am begining to wonder if I bought a Buick! Dealer has made necessary repairs but has done little to build my loyalty. Again, is this a GM dealer? Lesson learned: dont buy a failed model that has sat on the lot for over a year after build date (October 2002).

NICE Car Bad Back Seat - 2003 Infiniti M45
By logan2744 - June 21 - 5:27 pmPurchased the car about 8 months ago. It had 124,000 miles on it. I was on a local government auction site and saw it. I wasnt even looking for a car. I was actually looking for something else not car related. It had issues. Needed paint, starter, driver seat and some tlc. I checked for recalls and found that it had 2 recalls that needed to be done. Infiniti fixed them. While at the Infiniti Shop they saw that the gas gauge wasnt working properly. That was a $1000.00+ to repair. So after getting it painted, a new driver seat, starter and putting some tlc in it at an additional cost of $1000.00+ I finally think I have a great running car. Car has some get up to it.
