NHTSA Complaint #11595715 — 2022 RAM 3500

The Deisel Exhaust Fluid (DEF), SUPPLY LINE (part #57008975AA) has been replaced on my truck 4 times in 113 k miles. It now needs replaced again. The last 2 times were less than 5000 miles each. It is a plastic line that runs from the DEF tank and passes nearby the exhaust filter which is very hot. A RAM dealer in Georgia told me they have sold/replaced many of these lines. When cracked, they leak DEF in large volumes on the ground which then becomes contaminated.
