I just bought a new Promaster van and I noticed the 2 of the three plastic underbody shields are missing under the engine compartment. Seems all of the vans on the dealers lot are missing them too. The parts schematic shows them there and the are priced over $1500 to replace. The dealer doesn't know why they are not installed from the factory but I can buy them. I'm worried about starting a fire as the cat converter is exposed near the ground and very hot. Contacted Chrysler but they just give me the run around.
