NHTSA Complaint #11652149 — 2018 CHRYSLER PACIFICA

At startup there has been a noticeable misfire, and a rough start condition. Check engine light came on shortly after buying it (used) with a P0305 code and low coolant was observed - Cylinder 5 misfire. Sparks plugs were replaced and coil was swapped and there was an immediate difference in it running better and less of a noticeable misfire. few weeks later check engine light comes back on and noticed there was a drop again in coolant levels. Topped off coolant and re-checked everything and P0305 code returned. Code has been intermittent but just got it into a shop for further investigation and found a new head was needed where this is a common problem in shops and Chrysler is now recommending to have the head replaced as part of this fix due to problems on their end. Shop it's at won't take the risk of a head replacement, and we'll likely have to go through the dealer. There was previously a class action lawsuit that closed in 2022 to cover this issue. This needs to be a recall or further action needs to be taken before this leaves someone stranded in a dangerous situation - likely when the auto start stop can't restart a vehicle at an intersection due to rough start.
