It's right, happend to my 2011 ram almost two years ago, fairly common, except at the time they did mine Chrysler had no inventory in lifters so they went after market which lasted a year, they did it again but just the ones that failed, this time the cam was good, lasted 10 months, failed again then finnaly with a NEW service manager they re-did the job with Mopar parts and another two yeR warranty this is a VERY labour intensive job which is why I didn't do it cause it was my daily driver, the bill was north of 5k! Some say the problem exist with the MDS system and excessive idling ( I live in Canada so in the winter she idles in yhe driveway warming up ) there is a aftermarket set of parts to delete the MDS solenoids but honestly after what I went through with aftermarket I opted for OEM, any all fixed now, gave that truck to my son and bought a 2019 limited fingers crossed I don't go through it again but I loaded this one with extra warrenty, lol
