Friends, I have a 2012 300S with 70k miles. I also used to have an extended warranty. I was unaware of the left side head issue and recently through a code for #2 cylinder misfire. I had a local guy change the coil and the spark plugs. However, not sure if this will fix the issue but it is no longer throwing the same code, at least, not yet. I'm assuming if I take it to the dealer, they will not replace the heads even though this has been an issue for many Dodge/Chrysler vehicles. Any advice or guidance, other than just biting the bullet and paying to have it fixed. Thank you!
