Over the past few years squirrels have eaten through the fuel line of the truck just above the fuel tank multiple times. As soon as the ignition switch is turned on fuel gets pumped out very near the exhaust system. The driver may not notice anything wrong immediately causing a very real fire risk. Today is the fourth time I have experienced this issue with this truck.

Due to a faulty design and or materials used the fuel pump module assembly located on the top of the tank has prematurely corroded and caused a dangerous situation with potential threat to life as well as contaminating the environment. Gas is leaked out of the unit and can become very dangerous if unnoticed or not repaired. Vehicle was purchased new in 2012 and has only seen 4 winters. Mechanics at the garage stated it was a common occurrence they had seen in numerous vehicles and caused by a poor design in which snow and salt can accumulate on top of the tank ratting the unit and gas lines prematurely. I contacted the manufacturer and they were not concerned and considered it "normal" wear and was an unfortunate situation. Gas leaks when stationary and is leaked when system is pressurized spraying the undercarriage of the vehicle and a major concern for potential fire or explosion when gasoline is vaporized.

Pulling out of a snow covered parking lot the engine light came on dic then the message, reduced engine power, the engine began to run very rough at a lower idle speed, as began to happen the truck lurched forward and I had to press hard on the brakes very hard like I was fighting the engine speed to slow, then the message changed to service traction control, I had no control over the gas pedal and could only move at about 5mph, then the message changed to service stabilitrak, I got to another area of the parking lot, parked and shut off the engine for a few minutes and the issue would not go away. I was more than two hours from my home. I removed the red battery cable then replaced it and was able to start the engine and it operated normally for a while. One and a half hours later while driving 60mph it happened again and I cost off the interstate and could not get it running again. Had to be towed to a dealership. They said there was a service bulletin to replace the throttle body but want to charge me $215 to clean the other fuel related parts. This needs to be a recall. If it was a recall I would not have to pay $215 to complete the work properly.
