Other Fuel System Tank Assembly problems of the 2006 Infiniti QX56

We receive a letter from Infiniti company because I'm the owner of a infinity Qx56, year 2006 notifying me that the fuel gauge in some of the vehicle may be inaccurate due to a malfunction in the fuel level sending unit, that cause the instrument panel fuel gauge to inaccurately display that the vehicle still has some fuel, typically about one quarter tank, when the fuel tank is empty and that if this were to occur on my vehicle, the vehicle could stall, which could create an unsafe condition which could result in a crash. I never ago has this problem but I ever maintain the fuel level in my vehicle so the fuel gauge reads above the one half position, so I was very interesting to have my vehicle repaired, but I was based in panamã� city so I want to know how is the process for the persons that was outside of USA. Please call me back to my office [xxx] or to my mobile [xxx] or please mail the information to the following address: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.
