Infiniti M 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The M30's angular design aesthetics and on-road performance were viewed as outdated, especially considering a redesigned Acura Legend coupe was launched in 1991. The interior came in for criticism for its outdated ergonomics and lack of room.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 Infiniti M problems
The INFINITI M35, a luxury sedan produced by Nissan's premium brand, has been reported to have several common problems based on complaints from owners. Here are some of the most frequently reported issues:
- Groaning Noise from All-Wheel Drive Vehicles: Some INFINITI M35 owners have reported a groaning noise from their cars, particularly those with all-wheel drive. This issue seems to be related to the drivetrain and may require a thorough inspection and possible replacement of affected components.
- Intelligent Key Feature Issues: The intelligent key feature, which allows keyless entry and start, has been problematic for some INFINITI M35 owners. Issues include the car not recognizing the key fob, resulting in difficulty starting the vehicle or locking/unlocking the doors.
- Sketchy Power Windows: Some owners have reported issues with the power windows, including windows not functioning properly or getting stuck. This can be a safety concern, especially if the driver's window is affected.
- Excessive Engine Braking: Some drivers have reported experiencing excessive engine braking after releasing the accelerator, which can be jarring and unexpected. This issue may be related to the transmission or engine control system.
- Transmission Glitches: Transmission-related issues have been reported by some INFINITI M35 owners, including rough shifting or hesitation. These problems may require a transmission service or component replacement.
- Electrical Problems: Electrical issues, such as malfunctioning interior lights or power seats, have been reported by some owners. These problems can be intermittent and difficult to diagnose, requiring a thorough inspection of the vehicle's electrical system.
- Bose Sound System Issues: The Bose sound system, which is designed to reduce noise, vibration, and harshness, has been a source of frustration for some INFINITI M35 owners. Issues include headaches and blemishes in the otherwise above-average dependability performance.
It is important to note that these issues may not affect all INFINITI M35 vehicles, and the frequency and severity of these problems can vary. If you are experiencing any of these issues with your INFINITI M35, it is recommended to consult with a certified mechanic or your local dealership for further assistance.

Infiniti M 2004
- Date Of Incident: 2010-09-09
- Date Complaint: 2012-03-02
- VIN: JNKAY41E84M
- Components: FUEL SYSTEM, GASOLINE
- Summary: AFTER APPROX. 60,000 MILES I BEGAN TO STALL OUT. THIS HAPPENED 2 TIMES BEFORE I COMPLETELY FIGURED OUT THAT I WAS OUT OF GAS BUT YET MY FUEL GAUGE READ HALF A TANK OR MORE. AFTER STALLING A 3RD TIME AND FOUND OUT THAT IT WAS MISREADING THE FUEL LEVEL AND LUCKILY I HAD PURCHASED A GAS JUG TO CARRY IN MY TRUNK AT ALL TIMES. INFINITI REFUSED TO GIVE ME A FREE EVALUATION, $140 COST, AND I ENDED UP HAVING THE SENDING UNIT REPLACED 700$ PLUS IN REPAIR. AFTER ALL THIS THE CAR HAD THE SAME PROBLEMS. DURING THESE TIMES IN STALLED I WAS ON A MAJOR BRIDGE IN NORTHERN NEW JERSEY. IN PANIC I TRIED TO GET ONTO THE SHOULDER AND FEEL MY CAR SEAT MY ALSO BE OFF-ALIGNMENT NOW DUE TO TRYING TO JERK MY BODY AROUND TO SEE TRAFFIC COMING ON THE BRIDGE WHEN MY CAR COMPLETELY STOPPED. I NOW HAVE A CAR THAT STILL NEEDS A NEAR INSTRUMENT CLUSTER, AND MAYBE A BROKEN DRIVER'S SEAT. I SPEND APPROX. $1200-$1500 IN TOWING/REPAIRS/GAS AND MANY MORE IN HEADACHES.TO MAKE MATTERS WORSE THE WHEN I STALLED I HAD TO LEAVE MY CAR FOR HOURS IN A PARKING LOT UNTIL I COULD GET GAS OR A TOW, AND A ROCK HIT MY WINDSHIELD FROM THE BRIDGE ABOVE AND NOW HAVE A CRACKED. INFINITI HAS TAKEN NO RESPONSIBILITY IN THIS MANNER AND AFTER SPENDING A LOT OF MONEY (AN ADDITIONAL $100 FOR A USED TEMPORARY INSTRUMENT CLUSTER AND $140 FOR THE ESTIMATE AT THE DEALERSHIP), I STILL HAVE A CAR THAT NEEDS A NEW INSTRUMENT CLUSTER, WINDSHIELD, AND PROBABLY A DRIVER SEAT PART THAT CONTROLS THE MOVEMENT. THEY DIDN'T EVEN OFFER A DISCOUNT FOR REPAIRS.NOW, I CAN'T SELL THE CAR MORALLY WITHOUT TELLING THE BUYER OF THE ISSUES. I DON'T WANT TO CONTINUE TO DRIVE AN UNSAFE VEHICLE, AND I DON'T KNOW WHAT TO DO .... I FEEL THAT 2003-2004 INFINITI M45 OWNERS ARE BEING PUNISHED BECAUSE THIS CAR WAS ONLY MADE FOR 2 YEARS AND BECAUSE OF THE HIGH PRICE TAG THERE AREN'T AS MANY SOLD IN THE US. THAT DOESN'T MEAN THIS ISN'T A HUGE ISSUE. *TR

Are you having problems with your Infiniti M?

Great car. I hope they build an M coupe with a high-output hybrid system as well!

A sports car in disguise. Smooth, quick, and oh so sweet. This car has all the creature comforts without sacrificing your need for speed, from the heated steering wheel to the cooled seats. With decent mpgs, blind spot detection, and lane departure warning, the Infinity M56X is not a car you should write off. It even has three power modes: one for economy, one standard, and one for sport.

Well, I've had several luxury vehicles over the years, including many hybrids. In my opinion, this car is absolutely the best. With 360HP and 30-32 mpg, it's hard to beat even in 2023. It's no surprise that there are very few for sale. I'm disappointed that Infiniti discontinued this model, the M35h and Q70 Hybrid.
