“I am having an issue with the fuel gauge on my 2005 Infiniti QX56. The fuel gauge is not reading correctly. It stops reading correctly once it reaches about half a tank of gas. I was driving on the freeway at night and I ran out of gas. This was a very scary situation because I had my kids in the car with me and at the time I had no idea why the vehicle completely shut off because my meter was showing that I had half a tank of gas. …”

After having it towed 3 times to Infiniti, they finally diagnosed the fuel sensor after we researched the problem and told them what to check. …”
