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The M30's angular design aesthetics and on-road performance were viewed as outdated, especially considering a redesigned Acura Legend coupe was launched in 1991. The interior came in for criticism for its outdated ergonomics and lack of room.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

Great running car! I love it. However, every time it rains hard, it won't start for 2 days. Does anyone know why? It's like something gets wet when parked in the driveway.

Welcome to this beautiful Infiniti! This car is a rare gem, and with your love and care, it will serve you well. It was ordered back in 1990 and has only had two owners, of which I am the second. The mileage is low as I only use it for work and shopping. Although it needs some work, which is expected for a 20+ year old car, I have already replaced many parts, including all 4 brakes. Thank you for considering this wonderful car!

This car is amazing! Despite being a bit old, it's incredibly reliable. I haven't had any major issues with it, and I think it's a high-quality vehicle. The Nissan engine is built to last, and with proper maintenance, it could easily last another 10 years. The only downside is that it's a bit small for my 6'8

I am someone who likes to save money. I also happen to enjoy driving cars that are fun. Professionally, I sell cars for a living. This particular car has exceeded my expectations, providing me with more value than I ever could have imagined for a price that was only a fraction of what I would have paid elsewhere.

This is a well-built luxury sports car.

The engine is great, although there have been some transmission issues. It is essentially a Maxima, but still a worthwhile purchase despite the known transmission problems.

This car may not be a sports car, but it is a luxurious one. Despite having a V6, it may be considered underpowered. However, I really like this car, especially because I love convertibles and needed something for commuting that would be suitable for winters. I have found this vehicle to be reliable and fuel-efficient (26 mi/gal). The interior styling is pretty cool, with real wood veneer around the dash, doors, and console. Additionally, it has some nice and convenient features. One of the drawbacks of this car is the cost of repairs. If you need to bring it to the dealership, be prepared to pay a hefty price. So far, I have been lucky.
