It's Like driving a Race Horse

If you want to take long cross country trips and are my age (63) then take breaks so you don't get sore. The seats are sports car seats, not plushy cushy seats. The suspension isn't soft or cushy either but let me tell you, hang onto your hat when you give it the gas!! You don't really need to slow down much to take a corner. There just isn't any body roll and this car can deliver. I grew up with the 1960's muscle cars and everything that went with it. I am female and a great grandmother, but I do enjoy driving in a sporty manner. Since I live in So Cal, I can drive the freeways with "authority". My M45 is 15 years old now and has 137K miles on it. Have NEVER had a repair on this car. Just the normal maintenance stuff. Now that it is older, there are more road noises that I hear and my CD player quit working but what would one expect at this age? The M45 doesn't like our dirt roads much and it doesn't absorb the stutter bumps very well but it does love a mountain road and a remote road where you can loosen up the reins and let her run. When you have it in the manual mode, it seems to lunge forward and you need to be prepared for that at a stop sign. Alot of people think the manual mode is worthless, but they don't let it wind out enough. Honestly, you need to have this car for a while and really learn how to drive it. In the years that I have had the M45, I have seen only 2 others like it. When I have taken to get tires or an oil change, the comments you hear are "This sure is a nice car and you don't see M's on the road" It is a very capable car especially for its weight but that is something I like because you feel like the car is solid and "on the road" not "floating above it". If you are looking for a strictly luxury car, then you probably won't think it's all that but if you want a combination of luxury and high performance, this is the one for you. The instrument panel some people find confusing but all you need to do is read your owners manual and you will see how easy it really is. There are multi-function controls so you need just to touch the component you wish to control and then look at the buttons numbered 1-6 and push the one that is appropriate. Easy peasy lemon squeezy!! THIS CAR IS SO MUCH FUN TO DRIVE!

Purchased 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 wasn't 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 wasn't 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.

This vehicle is reliable (at 90K miles) and still drives the same as when I drove it brand new off the lot. As an engineer, this car has all the technological gadgets one could want or need. Amazing driving performance (power - 340HP & 333 ft.-lb. of torque and handling) and style. I haven't had any issues except a recent gas gauge replacement by the manufacturer. This vehicle is incredible when I compare it to previous vehicles such as: 1991 M3 and Acura 3.0 CL.

The Original M45, a thinking man's perf. car

Tarek Wally, 06/30/2018
2003 INFINITI M45 4dr Sedan (4.5L 8cyl 5A)
5 of 5 people found this review helpful

In my opinion the styling is timeless, has aged well, and is very distinctive. I always have people coming up to me asking what it is, particularly in the captivating Red Garnet Fire paint. The acceleration is amazing, even more so at freeway speeds when you put the pedal down, the 5 speed auto downshifts to third and in no time you're at triple digit speeds, all the while the 4 cam V8 sounds exhilarating and happily loves to rev. Thankfully the 4 wheel discs slow with authority. In winter or slick conditions it's smart to be gentle on the throttle and I had no worries when winter tires are swapped in. Having never been stuck in Minnesota winters is a tribute to the predictable nature of the chassis and good driving skills. The biggest drawback is fuel economy, followed by rear seat leg room. The only seat you need to care about is the driver seat. It's a big shame these are such rare cars.

Jeckyll and Hyde

I still believe this car is a Jeckyll and Hyde. We're still enjoying the power, but the transmission isn't very responsive and the manual mode is worthless. The seats are comfortable and have nice amenities, but the driver's seat squeaks now. We still love all the gadgets, but they are difficult to use. We've encountered more issues, but we do have 108K miles now. The exhaust manifold was changed under warranty. Now it's cracked again - poorly engineered. We still burn a quart every 1,000 miles (108 quarts so far!) Tire wear is phenomenal. The originals ran 28K miles. The second set were Essenzia and were just changed. The new Hankook Ventas don't feel very good on the car.

M45: Great Machine

This is a great automobile! The body style is unique and sharp. Although similar lines to the new Cadillac, I find the M45 lines much more refined compared to the "boxy" look of the Cadillac. The interior is very handsome looking. The automatic retracting seat and lifting steering wheel for ease of entrance and exit is a nice touch. The tiptronic 5 speed transmission lets me enjoy additional acceleration and control when I want to have extra "fun". The audio controls on the steering wheel make audio operation safe and easy while in motion. The voice controlled audio and climate control system also make for ease and safety of control while driving.

I've had my M45 for a week now. It is by far the fastest sedan I have driven. It will smoke a 540, E430/E500, GS430, A6 4.2 for $10K to $15K less. The look is menacing, especially in Black. The 18" wheels with the low profile tires look HUGE. The interior is first rate and very quiet.

This car intrigues you. A true Jekyll and Hyde. Lots of power - Manual mode on transmission is worthless. Comfortable seats - Hard to reach seat controls. Nice wood and leather interior - console and glove box are loose. Lots of goodies - Too many steps involved to enjoy them. Feels great up to 120 mph - feels unsafe at 125 mph. Big car - Interior feels narrow. I like the handling and performance of my car, but it does not have give you feedback like my BMW 540i. This car is a sleeper. You can pull away from nearly every car on the road. Stereo system is very nice. Ours is black with tinted windows and chrome wheels - I think the best color for this car. Engine burns lots of oil!

I purchased this car 1 year ago fully loaded with 65k miles on the clock. The car gets loads of attention and compliments, my mechanic always compliments the powerful v8 and many get surprised when they find out the car has 340 horses under the hood. Ive had a few issues with the car, like the fuel gauge inaccuracy which has left me stranded a few times on the road. My camshaft position sensor failed me at around 75k miles. My only complaint is parts are scarce and everything must be special ordered from infiniti. Other than parts issues, recalls, and general maintenance this car is flawless.<br><br><br><br>

Obviously all used cars now and if you see one on the lot steer clear and let it rot on the lot. We have owned one now for about 4 years and up til recently have been some what satisfied. It has about 80K on it and everything is falling apart. Like previous poster gas guage is unreliable and it has been in the shop waiting for a part for over a week now. The whole instrument cluster has to be replaced!! A big rig has a tighter turning radius. Interior lights have been replaced a few times too and rarely work correctly. Infinities are not built to last.

Great Car / Little Annoyances

I bought this car used, Have had it one year now and love the car. It's 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 doesn't catch it and close it again. What a pain!

I 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!

I just purchased a 2003 M45 with 70,000 miles on it. I've always liked the style and the power is great. Its a great used car bargain I'm just glad I never bought it new. The quality is below luxury in my book. I also have a Lexus the quality of the material and finish is top notch. The Infiniti not so much trunk struts don't work, center arm rest is cheap and feels loose, sunroof liner coming apart, fuel guage not reading correctly (recalled ), engine doesn't start up on first try sometimes, and airbag light is on. Alot of issues for a car with 70k, but I've always wanted one and I dont regret buying it for $7500. Especially since its not a daily driver. I have a Gs300 and Yaris for that.

I have owned my M45 for just over 5 years. This has been the most enjoyable, reliable car I've owned and I've had 19 cars. After 5 years, it still turns heads at the styling. Odd and unique....which is why I love it. Not a lot of them on the road. The power is second to none in its class, the features are top of the line for a 2003 model and it handles better than any BMW, Mercedes, Lexus I've had the pleasure of driving. So many reviews complain of gas mileage.....what do you expect in a V8 performance car??? It's not a Hybrid!

This car had lots of positives, but the few negatives does sour our ownership experience. Our M45 has a very unique look, which I've come to like. The interior is still very nice. Our car still drives very well - it doesn't feel like 108K mi. The power is very impressive. The aluminum suspension components cut unsprung weight. A lot of things have broken, which is upsetting. Infiniti service writers are nice, but they will not fight for the customer. Our air bag light has been on since a hair over 50K mi. The warranty is good up to 7yr/70K, but they wouldn't fix it. The oil issue stinks. Due to the bad service, I won't buy again.

I have wanted this car since I saw the Gloria/Cedric models on the Nissan website in Japan. When I heard they were bringing it here and putting a V8 in the car I knew it was the care for me. The American auto reviewers have blasted this car's looks for some reason, but I have had more positive comments on it's beauty and style than I can count over the last 2 months. It just goes to show you never take a reviewer at his word, investigate for yourself. my car is Diamond Grafite with crome wheels, tinted windows and every goodie available, I love it and will buy another when my lease is up!

Been in the shop at least 15 times for repairs, 7 for the same thing. Hesitates when accelerating at low to medium speeds - great at highway speeds. Now gas gauge doesn't work, uses 1 qt of oil every 3,000 miles and pings like crazy when first started. Worst car I have ever owned.

2003 Q45 Oil Consumption, Defec Brakes

I purchased the Q45 in March 2003 and have 16k miles on it now. It has always been service by Infiniti wihtin the manufacturer specs. When I picked up the car, the front rotors were warped...they cut them. This problem has persisted over the past three years and they simply cut the rotors. Secondly, the car burns over 1 quart of oil per 1000 miles. As everyone else has experienced, Infiniti denies there is a problem, states that burning 1 quart per 1000 miles is normal. If you persist, they will then go through the "consumption test" and will try everything they can EXCEPT FIX THE PROBLEM. It borders on criminal to sell someone a $60K car with these problems and not fix the car.

I've 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 don't 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.

I've had this car for 3 weeks now, and I've gotten so many looks on the street! No one really knows what it is yet and that's what makes it even more fun!! The engine is really quiet even when you push it hard, and if you're not used to this kind of power, whiplashes won't be scarce events. The interior is beautiful, and it offers so much more than the BMW''s and Benz's and Lexus's of the same price range. As for fuel economy, my previous car was a 1982 Buick Electra V8, so the M45 sipps gas compared to that. Not saying it has great fuel economy, but I just don't think it's that bad.

I bought the first M45 in Austin and smoked a Porsche Boxter the first week. I looked at the new E500 and there was no comparison, especially for the price. I've had three Corvettes and this one will definately keep pace with my 93 and seems to handle better, suprising for a large four door sedan. Looks best in Black with chrome wheels. Very 70's in style which I like but with far more technology. Though I've had mine now for two months, I've seen only one other one here. It appears this car will be another "sleeper." I'll have fun smoking other "so called" competitors: 540i, GS 430 and E 500.

If you want quality, luxury, performance -- without owning the same car as every other joe on the highway - - this is a simple choice. Infiniti of Cincinnati is offering them for as little as $399 on a 39 month lease -- and nothing out there can touch that. Almost everyone that sees my car loves it (Graphite on Graphite with chromes). Most people think it is a Mercedes or Bentley. If you are at all considering a BMW 5- Series, Lexus G Series, Audi A6 or Mercedes -- you owe yourself an M45 test drive.

This car is truly a wolf dressed in sheep's clothing. It's benign exterior looks give no indication of the monster under the hood. Acceleration is "push you back in your seat" quick, and handling is precise. Anyone who picks a fight with this car will lose. It's insulting to this car to obey speed limits. Yes, trunk space is poor, they have wedged the fuel tank in between the rear seat and trunk. Alledgedly this is a safety issue.

This car rocks over any luxury sports sedan at its price, and some at significantly higher prices. The V-8 steps off the line nearly as fast as my boss's boxster, but I can fit three buddies in my car and all our golf clubs. I'm very happy with it. The styling gets knocked by some reviewers, but I like it, and get nice comments on its lines from folks all the time.

We had been looking for a new car and just happened on Infiniti, I took a Q- 45 for a ride first then a G-35 witch I realy liked but it was a little to small so the salesman says we just got a new car in want to give it a try, I said why not. Me and my wife took it for a ride and that was all it took after I hit the gas peddle the first time we looked at each other and knew this was it. This was Oct.2 ordered Oct 4 and took delivery Jan. 13 and have put almost 7,000 miles since.

When I read some of the "professional" naysayer reviews, I have to laugh. They obviously know nothing about real-world ownership. I shopped around, and while there are plenty of great cars out there (BMW 540, Lexus LS/GS 430, etc.), this one undercuts them in price- big time. I've gotten so many compliments on its exterior, but when I take my friends for a ride, they're all blown away. This car could easily cost $5K more based on performance alone. I was initially concerned about the turning radius, but it's actually been just fine for me.

one week and 1,000 miles already. This car is FAST but get ready to fill the tank. This is a muscle car as well as a luxury car as well as a head turner.

If you are looking for pure heart pounding performance this is the vehicle...I've only had my car for 1 week and all I can say is I never knew an Infiniti could have this affect on a human being....nothing and I mean nothing can touch this beast.....they also have great deals right now....hurry.

I just bought my M45 almost a week ago and so far I am very pleased with my ride. I just love the power this car possesses underneath it's hood. I am also very careful on how I have my foot to the pedal, since this V-8 monster will definitely gulp down its gas tank. Overall, I am very happy with the build, interior and exterior wise. Also, with lots of hp, this is seriously one very fast car. The ride is pretty smooth too.

One of the best cars I've ever driven next to the Mercedes cars. The car is a head turner to most, but is subject to criticism by a few due to the styling, but that makes it all the better. This car doesn't follow the same lines or mold as the other cars. Infiniti stepped outside the box on this 03-04 M45 setup and I'm glad they did. The car is strong and handles well in the straight away. I haven't had any issues since I bought it in 2005. No gas gauge or oil issues.

The 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.

My former daily driver was a BMW 540i. This car is much more comfortable with superior build quality. While it doesn't handle as well as the bimmer, the acceleration and overall performance is impressive. This is our fourth Infiniti (between my wife and I) and a very pleasant choice.

This car is in a class of it's own. Since the purchase of my m45 I have had many people ask about it. And a lot of thumbs up on the interstate. It is 197in long and 340hp a lot faster than the cars in the 60-70k range. "bmw" "benz" O and the VDC has saved me from skiding more than once in wet weather.

Rot Lot Causes Too Many Tow Ins!

I got a really great deal on a left over 2003 M45 demo with 1200 miles. The dealer advertised $10,000 off MSRP and that's 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). I've 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: don't buy a failed model that has sat on the lot for over a year after build date (October 2002).
