Twice now, when I attempt to refill the fuel tank, with the truck off, the tank "burps" out about 8 to 10 ounces of gas which spills on me, the left side fender and left side tire. When I put my ear to the filler neck, I can hear the fuel pump running (with the truck OFF). I sent the dealer a video off the noise I hear at the filler neck. Also the discoloration on my new Michelin ten ply tires. Went to dealer, Master Mechanic had no idea. He also didn't know where the battery was in the truck to perform the open recall. Service manager said he would start a TAS report with Toyota and let me know. I month went by and I heard from no one. I sent the service mgr two texts, no reply to either, I called the service writer and he said he would get back to me....I'm still waiting. I called Toyota Help line today. They said they would call the dealer. I while later, the service mgr called me and had no excuse for ignoring me. He wants to keep the truck of six months to duplicate the video I sent him. He doesn't have a Sequioa loaner and he said even if he did, I could NOT tow with it since its against their policy. I tow ever day with the truck. Being a retired Professional Engineer, I think there is a software issue telling the fuel pump to run to purge the charcoal canister every few months. I'm must be hitting that frequency when I refill. It would be nice to talk to a Toyota Engineer, or maybe they want to wait for it to burst into flames.
