2009 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The M30's angular design aesthetics and on-road performance were viewed as outdated, especially considering a redesigned Acura Legend coupe was launched in 1991. The interior came in for criticism for its outdated ergonomics and lack of room.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 2009 Infiniti M45 problems
The Infiniti M45, a luxury sedan produced by the Japanese automaker, is known for its powerful VK45DE engine and stylish design. However, like any other vehicle, it has its share of common problems that have been reported by owners.
One of the most common issues with the Infiniti M45 is related to the engine. The timing chain tensioners in the 2003-2004 models have been known to wear out prematurely, leading to a rattling noise in the engine. Replacement of the failed sensors is the only solution to this problem.
Oil leaks from the valve covers and oil pan are another common issue with all models of the Infiniti M45. These leaks can lead to a low oil level in the engine, which can cause premature engine wear and failure. To solve this problem, it's important to have the valve covers and oil pan gaskets replaced and to ensure that the engine's oil level is regularly checked and maintained.
Overheating due to a failed radiator is another common problem with the 2003-2004 models of Infiniti M45. A failed radiator can cause the engine to overheat, which can lead to catastrophic engine failure if not addressed promptly. Replacement of the faulty radiator is the only solution to this problem.
In addition to engine problems, the Infiniti M45 is also known to have transmission issues. Some of the common transmission problems experienced by Infiniti M45 owners include delayed or harsh shifting, transmission fluid leaks, and failed torque converters. These issues can lead to a less than smooth driving experience and can be costly to repair.
Another common issue reported by Infiniti M45 owners is related to the moonroof. A rattle is a commonly reported problem, which can be caused by a variety of factors, including loose screws or worn out parts.
Finally, some owners have reported issues with the passenger window "AUTO UP" feature. This feature allows the window to roll up by itself when the button is pressed once, but in some cases, the feature may not work properly, requiring the button to be held down in order to roll up the window.
In summary, the Infiniti M45 is a powerful and stylish luxury sedan that can provide many years of driving pleasure. However, like any other vehicle, it is important to stay up-to-date with routine maintenance and to address any issues promptly in order to ensure the vehicle's longevity and reliability. Common problems with the Infiniti M45 include engine issues such as timing chain tensioner wear and camshaft position sensor failure, transmission problems such as delayed or harsh shifting and transmission fluid leaks, moonroof rattles, and issues with the passenger window "AUTO UP" feature. By staying on top of these issues and addressing them promptly, Infiniti M45 owners can continue to enjoy the driving experience that this vehicle offers.

I test drove a Volvo, Saturn, BMW, Mercedes, Audi, and Lexus. However, none of these other cars were as much fun to drive or had such great technology features as the Infiniti. My M45 is fast, easy to drive, and comfortable, with more leg and head space than Audi, BMW, or Mercedes. What a smooth ride!

We had a 2003 M45, and we thought that car was nice. However, the 2007 model is a significant improvement. It beats the 550 in every way!
-
I just wanted to share my experience with this car. I absolutely love it! The way it handles the road is just amazing and the acceleration is so smooth. Although, I do wish that it had some standard features like an Auxillary plug and a Bluetooth system that would allow me to connect my music, not just my phone. Another feature that would be great is automatic wipers. But overall, I think this car is amazing and I plan on keeping it for years to come!

I'm thrilled to share my experience with the Infiniti M45 Sport! After a year of researching and dreaming of the perfect sports sedan, I finally found it. This car has exceeded all my expectations, and I couldn't be happier with my purchase. Of course, with 335 hp, the fuel mileage isn't great, but that's to be expected with a hot rod like this. I do wish it had a six-speed transmission, and the high-beam headlights could be better, but these minor issues wouldn't stop me from buying this car again. Even without the Bose 5.1 surround-sound system, the regular Bose system is impressive. I just took it for a spin through the mountains, and I can't stop smiling!

After reviewing several cars from BMW (3 and 5 series), Jaguar (XF), Mercedes (C class), and Lexus (IS F), I ultimately chose the M45 sport, which is almost fully loaded (except for the mobile DVD system). While each car has its own unique features, the M45 offers the best overall value and performance. It boasts great performance, plenty of space, excellent design, and the latest technology features. Unlike the other cars, which were lacking in some areas (for example, the IS F lacks space and the Jag lags in technology), the M45 excels in every aspect and is reasonably priced compared to its competitors.

This car comes complete with every possible feature, including DVD, Bluetooth, navigation with voice recognition, and more. The only area that could use some improvement is the Sport Rims. The roads here in New England are not the best, and the sport rims have caused major cracking to the wheels twice, which had to be replaced. While this is not necessarily a flaw, normal driving conditions in New England include potholes, and in hindsight, I would have chosen more durable rims. Although the sport rims give a better appearance, it's important to consider the practicality of the rims for the area.
