First tank of gas....no problems.....second tank.....no problems......third tank.....I noticed at around 40km driven, the gas gauge registered about one quarter empty.....then a few clicks more....it appeared to be a third empty. I toppped up the gas tank, thinking it might be bad gas, or someone somehow is siphoning gas, or I have a gas leak... Initially no problems, then the same thing happened again....I came home, turned around in the neighbours driveway which has a substantial dip....and the gas gauge returned to where it should be for the amount of driving I have been doing......Has anyone else had problems with their gas gauges misreading?I take it into the Nissan dealer on Monday. I hope I havent bought a lemon(because that would just be my luck) If so, its going back to the dealer....
