Three problems related to other fuel system tank mounting have been reported for the 2011 Jeep Wrangler. The most recently reported issues are listed below.
Every time I fill up my gas tank it clicks once to shut off and then fuel comes shooting out like a geyser. I have tried pumping slowly and all different positions with nozzle and that doesn't help. A huge amount of gasoline spits out everywhere.
My gas tank overflows at the pump every time I re-fuel starting in January, 2015, 5 months after my warranty expired but with only 22,000 miles on the vehicle. The pump will shut off when full, then shortly after, overflow spills out onto the ground. The only way to prevent this issue is to guess when it is getting close to full and stop the pump before it is full. A significant amount of fuel splashes on me if I'm too close, on the body, bumper, and ground, causing a dangerous situation that could easily lead to a fire.
Excessive fuel spit back when refueling, even after gas nozzle is stopped. Gasoline "bubbles" and an excessive amount comes out of the tank even if not full but close to full.
