I recently purchased my vehicle from big star dealership in baytown TX. At a little over 1000 miles I was towing a camper. The vehicle stalled, fuel pouring from engine. It was towed and repaired due to fuel pump failure. At a little over 3000 miles the vehicle would not start. Dealership initially said water contamination then changed it and said gasoline contamination and now they say def contamination. The vehicle stalling the first time almost caused me to wreck the vehicle.
