I have a 08 Ram 1500 (5.7 hemi), it only has 23 km (14k miles) and has had numerous problems. The latest was the ambient temperature sensor. Low voltage from the sensor turned on the check engine light. Fault turned out to be moisture and very mild corrosion in several connectors. This truck is not abused, it is bathed weekly, sits in my heated shop Jan to May to keep the salt off of it, but has not had the engine shampooed.

The dealer blew out the moisture and sprayed the connectors. The dealer advised that the cause could be the windshield antifreeze. Apparently the antifreeze (good down to -40C) may be corrosive.
Is there any validity in this comment, is this the start of a major problem in the future.

Thoughts?
