general problems of the 2004 Infiniti M45

I ran out of fuel on a busy highway in stop and go traffic because the fuel gague registered full when the tank was actually empty. These gauges have major internal issues resluting in what may be a serious safety concern. . Read more...

Car's fuel gauge indicated nearly 1/2 tank of fuel remaining when tank is completely empty. I found out the hard way -- was driving, made a right turn onto a busy road, hit the gas and the engine died. If this had happened on I-75, particularly the 20+ mile stretch that's under construction and has no shoulders, this probably would have resulted in a major accident.

Purchased a 2004 Infiniti M45 with 76k in may 2010. Within 2 days of buying the car the check engine light came on. I had it scanned and it said "fuel sending unit" so I replaced that part and the light went off. About 2 days later, the gas tank was about 1/4 tank shown, and I watched the fuel gauge needle move from 1/4 tank to "full" at the stop light. Shortly thereafter the check engine light came back on. I did a quick "google" search and found multiple online forums discussing this topic and the real fault is the gauge cluster. I contacted a local Infiniti dealer and asked about the problem and was told "it's only happened a few times" but I had pages of other owners posting on the forums saying it had happened to them. The dealer told me it would be $800 to replace the gauge cluster, so I said "no thanks" and had my original cluster repaired with a lifetime warranty at bba remanufacturing and it has worked perfectly since September 2010. Prior to repairing the original one, I purchased a brand new gauge cluster on ebay, but it was not for my model with icc and nav, so I have spent money buying a gauge cluster and repairing my original one.
