I have the TSB where the gas sensors dont allow me to fill up my tank. I can only fill it to little over the 3/4 tank mark. I am still covered under a powertrain warranty and I was curious if the dealership will do this for free. Any help please soon before my warranty runs out.

 

My 2004 was hard to fill, too, there may be a tsb for other than 2007. these should be on the NHTSA web site too.

Just set up a service appointment and give them the TSB number. Make sure they have the parts ahead of time if needed.

Good luck
