I bought a 2017 Promaster City with the 2.4L in 2020, with 120,000 miles. After the first oil change I replace the pan because it was so far gone. It's not unique to Mopars either. When I ran the local city vehicle fleet, we had all International dump trucks, both single and tandem axle, all with the DT466. After the first one got to be about 5 years old, I started keeping an oil pan and a set of bolts (like 28 of them in 2 different sizes) in inventory. Not only would the pans rust out, the bolt heads would rust away. We didn't use any of the high-tech ice melt products, just plain old salt from the Detroit salt mine. The rest of the undercarriage would still be painted black with the oil pan rusted and seeping oil...
