Hello I have a 2015 Durango with the v6 engine., 75,000 miles, this past week I have noticed the engine making a louder ticking noise than normal, can easily be heard when in front of the car. and sounds like the lifters/rockers ticking, which from a bit of research sounds like a common problem with these engines. There have been no performance issues or dash lights triggered so far. My question is would this be something that needs to be addressed immediately and will it only get worse? What would the cost be for the fix? Any help would be greatly appreciated.
