2008 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The M30's angular design aesthetics and on-road performance were viewed as outdated, especially considering a redesigned Acura Legend coupe was launched in 1991. The interior came in for criticism for its outdated ergonomics and lack of room.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 2008 Infiniti M45 problems
The Infiniti M45, produced from 2003 to 2010, is known for its powerful VK45DE engine and luxurious features. However, several common issues have been reported by owners of this car.
One of the most common problems with the Infiniti M45 is related to the timing chain tensioners. In the 2003-2004 models, the timing chain tensioners have been known to wear out prematurely, leading to a rattling noise in the engine. This problem can be solved by replacing the faulty tensioners with updated parts.
Another common issue with the Infiniti M45 is related to the camshaft position sensors. In the 2003-2006 models, the camshaft position sensors have been known to fail, resulting in rough engine running and reduced fuel economy. Replacement of the failed sensors is the only solution to this problem.
Oil leaks from the valve covers and oil pan are also a 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 these common issues, there have been reports of problems with the transmission, such as delayed or harsh shifting, transmission fluid leaks, and failed torque converters. These issues can be caused by a variety of factors, including worn-out parts, low transmission fluid levels, and damaged sensors. To address these issues, it's important to have the transmission inspected and repaired by a qualified mechanic.
Despite these common issues, the Infiniti M45 is generally considered to be a reliable and well-built luxury sedan. By staying up-to-date with routine maintenance and addressing any issues promptly, owners can enjoy many years of driving pleasure from their Infiniti M45.

Congratulations on your new car! It's great to hear that you've been following this model since the redesign in 2006. When your 2003 Volvo S80 lease was about to end, you saw a special on the website and went to the local dealer. They were able to set you up with a fantastic M45 Sport, even though you initially went in to get an M35. The 8 cylinder is only 1 mile per gallon different in the MPG, and the power of the 4.5L is quiet but very muscular. The interior comforts are great, and the overall appearance of the car brings many compliments. You got a 21-month lease on the car at about $100.00 per month more than you were paying for your S80. It sounds like you're really enjoying driving this machine! Thank you for sharing your experience with us.

Hi there! I wanted to share my experience with the M45. I've been driving it for 2 months now and I have to say, I absolutely love this car! It's been such a joy to drive and I haven't encountered any issues whatsoever, not even a small one. In fact, I've already put almost 4500 miles on it! Thanks for letting me share.
-
I bought this car after testing the 550i and I must say, the performance is outstanding! It handles like a sports car but still rides smoothly (thanks to the 19-inch wheels). The interior is quiet and serene even at high speeds. I find myself regularly going 100-120mph without even realizing it. The exhaust note is also quite sweet. Additionally, the low beam headlights are the best I've seen in any car - the road is evenly lit with bright white light. However, the high beams are unfortunately quite lousy. Lastly, the leg room in both the front and back is class leading.
-
Excellent... upgraded from an early (March 2005) M35 Sport.

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!

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.
