I'm not mechanical - widowed older female loving my Jeep. I've had my JK since 0 miles, it now has 80K. I have religiously had the oil changed and had routine maintenance done at a dealership. Yesterday took it to a dealership for a "ticking noise" tech said it was the right side rocker arm. I have extended warranty, the warranty company wanted proof I had maintained the Jeep. I'm one of the people that keeps receipts so I was able to provide proof of oil changes from day 1 (well really from mileage 3k) When I called warranty company they told me they have been alot of this same problem. Looking this up I found it was a know problem in 2011-2013, nothing on 2016. My concern is they fix one rocker arm, what about the others, is this something I will be having to deal with even after warranty? TIA for any info to take to dealership
