What owners say about the engine

Verbatim from NHTSA complaints, newest first
“I originally took my car to Reedman toll in 2021 due to frequent issues with the batteries needing to be replaced and the car not starting. At the time I was told it was related to a recall, and they fixed it. However, over the last year I have continued to have various problems with the car. The batteries were replaced numerous times. The check engine light and stop start unavailable light going on randomly. The car also started having electrical issues like the radio would just turn off on its own, or the automatic car doors would not open. The car also started feeling jumpy and shaky upon starting, and when the car is off there is a thumping noise. This thumping noise is still heard when the car has been off and parked for hours. The car will be off and I will get in it and hear the thumping before the car starts. Over the summer the problems became more frequent, and on August 31st it would not start, and I had to have it towed to Reedman. Reedman said my started was bad and also the fuse box shorted. They had my car for 10 days, and during this time I paid $500 out of pocket for a rental. I paid $2000 to Reedman for these repairs. I got the car back, and…”

“First, I had camshaft related error which turned out to be a bad intake camshaft on bank 1. The Camshaft, all rocker arms, lifters, camshaft adjuster and all VVL actuators have been replaced with genuine mopar parts. 3 weeks latet, the head gasket on bank 2 failed, caused coolant to leak into the cylinder. The van has 89k miles, very clean and always maintained on time.”

“Head gasket blown! Vehicle is under 100k miles, never overheated, service properly maintained. When researching symptoms, I discovered I am one of hundreds if not thousands of 2017-2018 model Pacifica owners who have suffered this issue. Heads are known to be faulty and Chrysler will not address the root of it. It's very possible this could lead to a locked engine while driving and cause harm to driver or others.”

“We had to replace both head gaskets last July with only 70,000 miles on the vehicle. The repair cost was 4,600.00. This August, we started experiencing coolant leaks again. We discovered the cylinder heads are warped now. This was checked last year and it was not the main issue then. It is extremly disappointing that now at 80,000 miles we are looking at another 5000.00 repair. There needs to be a recall on the engine cylinders and head gasket.”
