Consumer Description

Starting smelling gas inside of the cab, at first thought it was non-issue, but the smell persisted. Several days passed, and when I went to warm up my truck in the morning smelled a strong gas odor, and when I looked under the engine - there was a pool of gas, and gas was leaking. Took it in to the dealership (thinking it was a simple loose filter line) but they now say that it is more than that. Not sure if this has been a re-occurring issue with these new trucks, but it could have been a very dangerous situation.
