2003 Infiniti M45 problems
The Infiniti M is a line of mid-size luxury (executive) cars from the Infiniti luxury division of Nissan. From 2013 (model year 2014) on it has been marketed as the Infiniti Q70, reflecting the company's new naming scheme.
The first iteration was the M30 Coupé/Convertible, which were rebadged JDM Nissan Leopard. After a long hiatus, the M nameplate was used for Infiniti's mid-luxury sedans (executive cars). First was the short-lived M45 sedan, a rebadged version of the Japanese-spec Nissan Gloria. The next generations, the M35/45 and M37/56/35h/30d, became the flagship of the Infiniti brand and are based on the JDM Nissan Fuga.
First generation (1989–1992)
The Infiniti M30 was a 2-door coupé based on the Japanese market Nissan Leopard (chassis code F31). It was launched in 1989 for the 1990 model year as a luxury coupe alternative to the Infiniti Q45, and was intended to be an alternative to the Lexus SC and Acura Legend coupe for the North American market.
Unlike its competitors that were designed with the American market in mind and were launched as brand-new models, the M30 was based on a somewhat dated platform that was originally designed for the Japanese market; when the Leopard was imported to the United States, few changes were made to the exterior but the interior was revised to better suit American tastes; a leather interior was standard in the M30, and several features in the Leopard such as a center-mounted television screen and a digital instrument cluster weren't available in the M30 as those features were perceived as gimmicks in western car markets.
The M30's angular design aesthetics and on-road performance were viewed as outdated, especially considering a redesigned Acura Legend coupe was launched in 1991. The interior came in for criticism for its outdated ergonomics and lack of room. While the Japanese-market Leopard had received a new dashboard along with the 1988 facelift, economics precluded making a left-hand-drive version of the new dashboard and the M30 was instead fitted with the LHD version of the R31 Skyline's rectilinear dashboard, first presented in 1985.
The M30 made up for these deficiencies in its somewhat lower price; whereas the 1990 Acura Legend coupe started at $27,325 before options and the 1990 BMW 325i started at $24,650 before options, the M30 started at $23,500, and had no factory options, per Infiniti's pricing structure used at the time. Dealerships offered an in-car cellular telephone and in-dash CD player as optional accessories, amongst other items.

Common 2003 Infiniti M45 problems
The 2003 Infiniti M45 has several common problems based on complaints from owners of this car. The most-reported problem is the exhaust manifold cracking.
Another common problem with the 2003 Infiniti M45 is the failure of the rear seat 2-way adjustable head restraints. This issue affects the interior comfort and safety of the vehicle, particularly for rear-seat passengers.

Positive 2003 Infiniti M45 car reviews

If you're searching for a vehicle that delivers pure heart-pounding performance, look no further. I've only had my car for a week, and I must say, I never knew an Infiniti could have such a profound effect on a person. Right now, they're also offering some fantastic deals, so don't wait too long!
-
My wife and I were in search of a new car when we stumbled upon Infiniti. I test drove a Q-45 first, followed by a G-35 which I really liked, but it was a bit too small for our needs. The salesman then suggested that we try out a new car that had just arrived. We decided to give it a go and were blown away from the moment I hit the gas pedal. We looked at each other and knew that this was the car for us. We placed an order on October 4th and took delivery on January 13th. Since then, we have driven almost 7,000 miles and couldn't be happier.
-
I absolutely love driving this car! It's definitely one of the best cars I've ever driven, right up there with the Mercedes cars. While some people may criticize the styling, I think it's what makes this car a real head-turner. Infiniti really stepped outside the box with the 03-04 M45 setup, and I'm so glad they did. This car doesn't follow the same lines or mold as other cars, which makes it all the more special. Plus, it's been incredibly reliable since I bought it in 2005 - I haven't had any issues with the gas gauge or oil. Overall, I couldn't be happier with my Infiniti M45!
-
My former daily driver was a BMW 540i. However, I must say that this car is much more comfortable and has superior build quality. Although it may not handle as well as the bimmer, the acceleration and overall performance is still very impressive. This is actually our fourth Infiniti (between my wife and I) and we have found it to be a very pleasant choice.
-
One week and 1,000 miles already! This car is so fast, but get ready to fill the tank. It's a muscle car, a luxury car, and a real head-turner!

Are you having problems with your 2003 Infiniti M45?
Edwin Koepp 2024-05-21
Congratulations on your purchase! It sounds like you got a great deal on a 2003 M45 demo with only 1200 miles. However, it's unfortunate to hear that you've experienced some reliability issues with the car, including new tires, a new battery, and a new fuel pump. It's great to hear that the dealer has been able to make the necessary repairs under warranty, but it's understandable that you may be feeling frustrated. It's important to remember that sometimes even the most reliable cars can have issues, and it's great that the dealer has been able to address them for you. Thank you for sharing your experience and lesson learned with us!
