2016 Ram Laramie Ecodiesel it has had every recall after VB1 recall ( replace EGR cooler) another check engine light led to replacing the SCR Cat. Then a week later it spent 3 more weeks at the dealership in order to get the DEF system active again. It made it a little over 10,000 more miles for a total 118,000 miles. I lifted the hood to check the oil and found all the engine oil in the coolant reservoir. I could not touch oil on the dipstick. No engine lights or codes showed up. I had recently subscribed to Uconnect in order to keep an eye out for any trouble. I’m hoping it is covered under the extended Emission Warranty. I would appreciate any input or information. The SCR Cat was covered. Has anyone else had these type of problems? I swear if I can get it running just one more time I will trade it sell it drive in the ocean. Beautiful truck drives good but Worst f engine ever made. Nothing but problems.

Oil cooler failure is common. Unfortunately gonna require draining all the coolant and multiple flushes to get all the oil out you can
