Coolant was low so it was filled with coolant. The reservoir was low again the very same day and the car was overheating (as well as the ac not working properly and blew hot air even when using cold) on the highway, barely making it to destination. The first diagnosis was an air vacuum caused a leak. The problem keeps reoccurring after the supposed fix.
The 4 cylinder engine on my 2012 Dodge Journey developed an engine coolant leak. Trouble shooting found the leak to be related to deterioration of a plastic part inside the engine. . . Dodge part# 68003582. . . Adapter c. The car was standing when the problem was diagnosed. If I had not had the part replaced a catastrophic engine coolant leak could have occurred while the car was being driven, leading to a full loss of coolant, overheating of the engine and seizing of the engine. I talked with Dodge customer service and they acknowledged awareness of the problem. The car has 89,000 miles. I consider this to be a serious safety problem.
