The National Highway Traffic Safety Administration has launched an investigation concerning Infiniti M45 sedans from the 2003 and 2004 model year. The government organization has reportedly received 43 complaints about inaccurate fuel gauge readings, and in 26 of these cases, the improperly calibrated fuel gauges have led to instances of engine stalling.

According to the NHTSA report, "The complaints show an apparent increasing trend, with most received within the past year." This investigation will encompass approximately 8,100 M45 models.

Speaking to Inside Line, an Infiniti spokesperson says that the automaker is aware of the NHTSA investigation and will "work to address any issues that arise from it." Hit the jump to read the official NHTSA statement.

Summary

The Office of Defects Investigation has received 43 complaints alleging inaccurate fuel gauge reading in model year 2003 through 2004 Infiniti M45 vehicles, including 26 incidents alleged to result in engine stall. All 26 incidents reported stalling because the fuel level reading indicated fuel in the tank when there was none. The complaints show an apparent increasing trend, with most received within the past year. A Preliminary Evaluation has been opened to assess the scope, frequency and potential safety consequences associated with the alleged defect.

      I was seriously considering one of these a few months ago, I spoke to one seller that had de-badged his and he told me that nobody ever knew what kind of car it was. I always liked how they marketed it as "A Muscle car with brains" and the ads always showed it street racing against various 60's muscle. Neat car because of its V8 and RWD but mainly because it looks like nothing else on the road.

          The way the grill interacts with the front bumper area is pretty lousy too. A custom body shop could take this car and rework the whole front grill/light section and make something pretty great though.

      I've always love this design on this 1st gen M. It reminds of a japanese version of the Pontiac Tempest GTO :)

      Not good on most fuel pumps to let thye tank run real low. The fuel pump is typically mounted inside the tank and the lquid gas around them helps them run cool. If you run the tank real low, the lifespan of the pump can be shortened due to the heat.

      looks vaguely like a crown vic squad car but more slab sided.

      I like to know how much gas is in the vehicle I'm driving, obviously.

      Looks like an Asian version of the Crown Vic to me, but anyway Chevys use to have a fuel gauge problem where if there were to much sulphur in the gas it would kill the indicator altogether, they used silver solder on the parts. I had an 76 chevy van with this problem, just made sure I kept the tank full.

      I love how this car has such beautiful, classic lines. It looks muscular while having a large greenhouse... It doesn't have random curves and unnecessary styling. It doesn't have beefy accents or portals on the fenders. It looks classic and clean...a Japanese form of American muscle...simple beautiful. Not everybody's cup of tea...that's what a Camry is for...

        I completely agree with Leunamme. This was a design success for Infiniti which was totally unsung. Strong, clean, minimal and I'd say a future classic.

          The back end of the 2003-2004 Infiniti M45 is somewhat reminiscent of the 2002 Toyota Camry a little bit, especially with the tail lights.

        If the windshield was steeper it would help with it's overall form, right now the greenhouse looks too upright dating this car into the 90's (which it's originally from as the Cedric). I prefer the next gen M45 for looks, although I agree with the tacky styling on the current gen M

      Gee, I forgot how ugly it was. How come this never makes it to the "Top 100" most hideous vehicles of all times?

        This car was more popular in the Japanese market where it was sold as the Nissan Cedric/Gloria for many, many years (I checked Wikipedia to find the info!). By the time that this car went on sale in the U.S., it had already been on sale in Japan since around 1998. Unlike the Japanese version though this Infiniti was sold with a V8 engine as the only option. The V8 in this M45 was never even offered on the Nissan Cedric/Gloria. Nissan only released this aging car to the U.S. in order to fill a gap until the 2006 Infiniti M was released which everyone knows was a major success.

        The car is very good looking. Infiniti's earlier sedans were just great. Think back to the first Q45. No grill, no wood inside. Just a very nice and well made car.

      It almost reminds me of an old muscle sedan with it's upright stance and square styling. I like it.
