2004 Infiniti MFuel system

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

2004 Infiniti MFuel system

Gas gauge assembly was giving incorrect amount of fuel in the tank. I ran out of gas and was stranded back in 2009. Had infiniti replace and fixed the unit. Now two years and about 20k miles later the fuel gauge assembly is not working again as confirmed by infiniti service today (1/30/2012). I've read many post where this seems to be an issue with the 2003-2004 m45 models. Information redacted pursuant to the freedom of information act (foia), 5 u.S.C. 552(B)(6) *tt

2003 Infiniti MFuel systemElectrical system

Purchased car from marin infiniti in august, 2011. Next day car stalled driving in a 50 mph zone and had to be coasted to side of the road across traffic. Fuel gauge was found to be inaccurate, gas tank was empty when gauge stated 7/8 full. Marin infiniti was unable to assist. Fuel sending unit was replaced for $400. Gas gauge continued to be inaccurate, giving false readings and even increasing and decreasing readings as the car was driven. My mechanic called a local infiniti dealer who stated this was a known...

problem and could only be cured with replacing the dash instrument cluster for $600.Car is currently in the shop for this repair. Contact with other infiniti m45 owners proves this is a known defect by the manufacturer which, depending on what personnel is are contacted at nissan/infiniti, has sometimes been covered under warranty and sometimes the manufacturer's reps deny the issue, forcing the public to pay for manufacturer's defects. *Tr
