NHTSA Complaint #11571894 — 2016 DODGE GRAND CARAVAN

Code P0302 - undiagnosed as of 2/14/24 mileage - 51833miles 2016 Dodge Grand Caravan with Braun Mobility Conversion for wheelchair June 2023, had transmission freeze up and replace by Dodge dealer. Later that day after picking up from dealer, "Engine" light came back on. Called and left message with dealer asking if they neglected to re-set codes and or reset check engine light. Called twice and left messages, no return call. Van functioning fine. I had no problems for months until I needed it SMOG tested this month. SMOG repair station said it won't pass SMOG and it's likely cylinder 2 misfire, which can be observed sporadically, although I have never had any issues driving at all. Engine light never flashes. The SMOG mechanic researched Dodge issues and said I may likely need to replace the engine, but that even the replaced engine is not guaranteed to not have the same problem, due to it appears to be a problem in the engine itself. There are countless reports online by Dodge Caravan owners reporting same code, but almost all of them report driving and/or idling issues. There seems to be enough consensus that there is something inherently wrong with certain year Dodge engines but there is still no recall or dealer support. I don't know who to believe. I need to get it to pass SMOG but don't want to replace the engine to do it if it has been driving fine.
