Dashboard Failed Problems of Infiniti M45

Wife had just reached 65mph on highway when engine died. Fuel gauge indicated 1/2 tank. I had heard that fuel gauge failures are common on this vehicle, so I came with a gas can and added 2gal. Car started without problem and was driven to nearest gas station to fill the tank. Car continues to run without incident since running out of gas. I now reset the trip odometer with each fill up, and refill before reaching 300 miles on a tank. Was told by Infiniti dealer that entire instrument cluster would need to be replaced, at a cost of approx. $1200.

The fuel gauge stopped accurately indicating the amount of fuel in the vehicle. Subsequently the car ran out of fuel while driving on local road causing disruption in traffic before it could be moved to the shoulder. After a cursory check to see if anything looked to be amiss, we decided to start with the simple solutions and work toward the more complex. We added 5 gallons of gas to the car and it immediately cranked and ran fine. This is when we noticed that the gas gauge failed to move. The gauge showed to be about 1/2 full before we added fuel and didn't move after adding the fuel. The fuel indicator has now moved to past full and hasn't moved since. We had an Infiniti dealer look at the car and they gave us an estimate of $1502. 00 to make the repairs. The malfunctioned occurred at or near 72,000 miles, well after the warranty period. Reviewing information on the internet shows that this appears to be a rather common occurence for this year/model. Often this was repaired by Infiniti in cars that were still in the warranty period.

Gas gauge failure on Infiniti m-45 2003 model. Gas gauge would read full - 3/4 full when the tank was below 1/4 tank. Would lead to running out of gas unless the gas was monitored by the number of miles between fill ups. This is a dangerous situation - owners potentially running out of gas when trying to cross an intersection pull out in traffic, etc.
