Once it warms up (I'm in winter Jersey NJ) my 2011 Pentastar has a ticking noise coming from the driver's side. I am at 59k miles and never had this issue before. To be honest, I don't know if it's cylinder head, rocker arm, or fuel injector noise. I still have an extended warranty and will take it next week, but I am mentally prepared for the dealership to say "we couldn't duplicate the problem" or that's normal. I had the #2 cylinder head replaced (common issue) at 45k miles. The car runs great and the engine light is not on. I would appreciate any input. I don't think it's the water pump because I haven's seen any leaks, but it sounds like it's coming from the driver's side, very noticeable by the tire area.
There are a few YouTube and internet postings, but nothing conclusive.
Edit: Found this post (This part ticks like crazy
) from the previous model, it does sound like coming from this area. I'll check again.
