Problems with FCA on a new truck warranty.

Just like the basic 3year, 36k mile warranty will only cover so much.
But........ An educated person would be able to argue the Federally Mandated 7 year 70k mile EMISSION warranty.
In which case if ur dealer is saying you need an O2 sensor or a Cat converter or PCM or Fuel injector, cool pack, etc.... One can simply argue the fact the the standard 3year/ 36k mile warranty has nothing to do with the Federally Mandated Emission Warranty That covers any and all emission components.......In some states. NY is one state where this is in force.

The California Emissions Warrantysays cars and trucks sold in California (and in other states adopting its rules) must cover design and defect issues for three years or 50,000 miles and cover certain high-cost emissions-related parts—such as catalytic converters—for seven years or 70,000 miles.
