2006 Infiniti M45 problems

infiniti logo

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The M30's angular design aesthetics and on-road performance were viewed as outdated, especially considering a redesigned Acura Legend coupe was launched in 1991. The interior came in for criticism for its outdated ergonomics and lack of room.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 2006 Infiniti M45 problems

The Infiniti M45, produced in the second generation from 2006 to 2010, is known for its powerful VK45DE engine and stylish luxury sedan design. However, like any vehicle, it has its share of common problems.

One of the most common issues with the 2006 Infiniti M45 is a failing crankshaft angle sensor, which can cause drivability issues. This sensor is responsible for measuring the position of the crankshaft and providing this information to the engine control module (ECM). When the sensor fails, it can result in engine misfires, stalling, and difficulty starting. Replacing the faulty sensor is the only solution to this problem.

Another common issue with the 2006 Infiniti M45 is premature wear of the timing chain tensioners in the 2003-2004 models. These tensioners ensure the proper synchronization of the engine's mechanical components, but when they wear out prematurely, they can cause a rattling noise in the engine. Replacing the faulty tensioners with updated parts is the only solution to this problem.

The camshaft position sensors in the 2003-2006 models of the Infiniti M45 are also known to fail, resulting in rough engine running and reduced fuel economy. These sensors measure the position of the engine's camshaft, which is critical for proper fuel injection timing. Replacement of the failed sensors is the only solution to this problem.

Oil leaks from the valve covers and oil pan are 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 the 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, some owners of the 2006 Infiniti M45 have reported problems with the rear active steering system (RAS), which is only available on the sport model

. This system uses sensors and actuators to adjust the steering angle of the rear wheels, improving handling and stability. However, some owners have reported issues with the system, including difficulty steering and a lack of response from the rear wheels.

In summary, the 2006 Infiniti M45 is known for its powerful VK45DE engine and stylish luxury sedan design, but it also has its share of common problems. These include drivability issues due to a failing crankshaft angle sensor, premature wear of the timing chain tensioners, failed camshaft position sensors, oil leaks from the valve covers and oil pan, and overheating due to a failed radiator. Some owners of the sport model have also reported problems with the rear active steering system (RAS). Addressing these issues promptly and staying up-to-date with routine maintenance can help ensure that the Infiniti M45 continues to run smoothly and provide many years of driving pleasure.

Positive 2006 Infiniti M45 car reviews

  1. Kip Cormier 2025-01-08

    This car is so much fun to drive! It's a four-door sedan that reminds me a lot of my 350Z, but it rides much more smoothly.

  2. Cale Russel 2024-11-19

    This car really impressed me! The interior, technology, and power are all amazing. In my opinion, it even surpasses the Lexus GS430 and the BMW 5 series. I am extremely happy with my purchase and Infiniti continues to impress me more and more.

  3. Rodrick Goldner 2024-11-15

    I'm so glad to hear that you're enjoying your new Q45! It sounds like it's the perfect car for you with its sporty design, spacious interior, and luxurious features. It's great to hear that it's also fast and quiet. Thank you for sharing your positive experience with us!

  4. Sid Feil 2024-11-13

    This is definitely an amazing car! I have driven both the BMW 545 and the Lexus GS430, but the M45 beats them both in terms of features. It is the fastest of the group, with the best handling and technology. The navigation system is simply amazing, and the sound system is the best I have ever heard. The motor never quits and gets you to 60 in 5.5 seconds or under. I have been extremely happy with my purchase so far. I previously owned a G35 coupe, and I truly believe that Infiniti makes quality cars that are right up there with BMW and Mercedes.

  5. Clemens Schaefer 2024-09-22

    This car is so much fun to drive! The AC seats are amazing and my wife always gets compliments when she takes it out. I have the sport package and it's fantastic. However, as a parent of a 1-year-old, I wouldn't recommend it as a substitute for a minivan.
