I been a mechanic for 13 years. I have a 2016 charger 5.7 with 75k that's starting to develop a lifter tap. This is the 2nd time trying to get this resolve before it becomes something bigger all I hear is we can't duplicate. I go to pick up car up today first thing I hear when I start my car is a loud lifter tap. I have purchased 2 vehicles at this location thinking about a 3rd but after them pushing my car out for the 2nd time I'm done with dodge. I believe they're faster at taking my money to sell me a car then fix it.
