2013 Infiniti M56 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The M30's angular design aesthetics and on-road performance were viewed as outdated, especially considering a redesigned Acura Legend coupe was launched in 1991. The interior came in for criticism for its outdated ergonomics and lack of room.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.
