The 2014 through 2018 3.6L Pentastar motors are covered under a tech service bulletin for their Drivers side valve train being manufactured incorrectly. This can lead to a misfire and hesitation to accelerate in an Emergency. This happened to me recently and I thought it was just a bad spark plug. Mechanic did a full check and believes there is a stuck valve in the engine on the exact same side that the 2014 to 2018 motors are prone to failure. I believe the 2012 and 2013 Engines are also prone to the same failures as their newer counter parts. As I was trying to accelerate to avoid an incident my car stuttered and started to misfire badly. Almost causing a collision. This happened without warning and never previously had this issue. Vehicle was completely mechanically sound before this. This can happen without any warning or signs its going to happen. And after bringing the vehicle to a mechanic and doing much of my own research it appears that the drivers side of the 3.6L v6 in my vehicle is currently under a TSB for the #2,4,6 cylinder head. This can cause the vehicle to have no power for a moment which if I were merging onto the highway and lacked powered could result in a rear end collision. Believe this is a safety issue as well as mechanical issue.
