NHTSA Complaint #11465803 — 2017 CHRYSLER PACIFICA

Since I purchased this vehicle used less than a year ago, I have had an issue with rough shifting or the vehicle feeling like it loses power then lurches when it finally shifts. Now over the past couple months I have had it in the shop 4 times, the 4th time it's at a Chrysler dealership. Check engine light comes on and is blinking, car is shaking and knocking terribly. the shaking does subside after you drive a minute and the engine warms up but the problem has progressively gotten worse each time the light comes back on as I do have to continue driving it. Now the dealership states there is condensation in the cylinder, indicated either a blown head gasket or a warped cylinder head but there is no way to know without tearing the whole engine out of the car and tearing it apart. I'm also told that with labor for a new engine from Chrysler I'm looking at about $11,000!!! and due to supply chain issues we don't know how long it will take to get the parts. I've had this vehicle less than a year and I'm over $1000 in on repairs already that have not fixed the overall problem. HELP
