2007 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The M30's angular design aesthetics and on-road performance were viewed as outdated, especially considering a redesigned Acura Legend coupe was launched in 1991. The interior came in for criticism for its outdated ergonomics and lack of room.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 2007 Infiniti M45 problems
The Infiniti M45, produced in 2007, is known for several common problems based on complaints from owners. These issues include engine problems, drivability issues due to failing crankshaft angle sensor, and oil consumption issues.

This issue can lead to poor engine performance and increased emissions. The average cost to fix this problem is around $2,500, with an average mileage of 59,000 miles.
- Drivability Issues Due to Failing Crankshaft Angle Sensor: This problem can cause the car to have difficulty starting, stalling, or jerking during acceleration. The crankshaft angle sensor is responsible for providing the engine computer with information about the position and speed of the crankshaft. When this sensor fails, it can cause drivability issues that can be frustrating and potentially dangerous for the driver. This problem is common in the INFINITI M45, and it is crucial to address it promptly to ensure the vehicle's safe operation.
- Oil Consumption Issues: The Infiniti M45 has been known to have oil consumption issues, which can lead to engine damage if not addressed promptly. The oil consumption issue can be caused by various factors, including worn piston rings, valve guides, or cylinder walls. Installing a catch can and keeping up with regular maintenance can help alleviate this problem and extend the engine's lifespan.
In summary, the Infiniti M45 has several common problems that owners have reported. These issues include engine problems, drivability issues due to failing crankshaft angle sensor, and oil consumption issues. It is crucial for owners to address these problems promptly to ensure the vehicle's safe operation and longevity.

I decided not to purchase the Sport model because it was intended for my wife and I was concerned about the harsher ride. Instead, I bought a used 2007 M45 with only 18K miles on it. It comes with both the Tech package and the Advanced Tech package. Although it may have 18

Excellent... upgraded from an early (March 2005) M35 Sport.

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'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!

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.
