We recently purchased a 2011 CX-9 and this morning, for the 2nd time, when filling up the tank the gas nozzle has not automatically clicked off when the tank is full. The first time I was manually filling it so noticed right away when some gas came out of the tank, but this morning I had the handled latched and was washing the windows before I noticed gas streaming out of the tank. Both stations were Exxon stations. Has anyone heard of or had this problem before? I have never experienced this happening in any car. Is it a problem in the design of the tank?

 

Probably there is something wrong with the filler on your car since the same thing happened at two different gas station. Next time fill up on a different brand gas station to confirm the issue. Then your your next stop is the mechanic.
