I have a 2014 gas PM with 160,000 miles on it. I recently had the oil changed "regularly maintained" and the following day I was expediting freight to NC and noticed a ticking while idling. I returned the following morning to GA and took it into the dealership to see if maybe they didn't fill up the oil all the way or tightened up the oil plug. The service advisor said he would have his engine guy listen to the ticking. The tech said it sounded like the rocker arm bearing was going bad and that they would have to tear the engine down to diagnose and fix. They gave me an estimate of $1700.00. Now I am kind of stuck because I need to cover any loads that may pop up " rental" and not knowing how long it will take to fix. I hope that this isn't going to start turning into a money pit. My van is my livelihood and it needs to stay on the road if my business is to succeed. Keeping my fingers crossed until I hear from them.
