Its not just pacificas.. anything using the 3.6 liter gas engine is suspect. The biggest issue is poor hardening of the rocker arms. You can hear a "tick, tick..tick" that sounds like a bad lifter or exhaust leak. Mine died in my 2015 TC at 60K miles. Took out the entire engine which was replaced under warranty. The service writer didn't even bat an eye when I pulled in. Knew exactly what it was without opening the hood. Took a month to get a new long block. The trans died 20K after that. I had extended warranty and I think after 2 months they are finally giving in this week to OK the work to fix it.

Chrysler 'Pentastar Tick' Lawsuit Says Warranty Is Faulty
A Chrysler "Pentastar tick" lawsuit alleges certain vehicles were excluded from a Chrysler extended warranty for the V6 engines. The lawsuit alleges the 3.6-liter Pentastar engines were designed in a way that causes excessive wear on the left cylinder heads which causes the left cylinder heads...

I guess I read the article a little differently. It says the "biggest issue" is cylinder head failures on the left bank in 2011-2013 Pentastar V-6s. Rocker arms came second. The article says, "Rocker arm failures likely aren’t as common as the internet may suggest. At the same time, it’s an important topic as rocker arms are one of the more expensive 3.6 Pentastar problems." Third is cooling system issues stemming from residual sand from the casting process, and fourth is oil pump problems that may be related to the same sand clogging issue.Its not just pacificas.. anything using the 3.6 liter gas engine is suspect.

The 4 Most Common FCA Pentastar 3.6L Engine Problems
Learn about the 3.6L V6 Chrysler Pentastar engine. 3.6 Pentastar common problems and reliability. How reliable is the Chrysler 3.6L engine?
The writer asks near the end if the Pentastar 3.6L is reliable. "Short answer – yes. The FCA 3.6L Pentastar engine is reliable. We’ll give the Pentastar above average marks for reliability. Again, there is a reason this engine is powering so many flagship vehicles from Dodge, Jeep, Chrysler, and Ram; the same reason it’s been around for a decade. The FCA 3.6L engine is reliable and efficient all while providing solid performance.
"That said, it’s not hard to continue Googling the 3.6L Pentastar engine and finding plenty of owners with problems. As far as we’re aware, some 10 million plus Pentastar engines were produced to date. That’s a lot of engines. All engines are prone to problems, especially with that volume of production. Mistakes happen. No machine or person is completely perfect. Sometimes reliability simply comes down to the luck of the draw.
"Fortunately, it appears the overwhelming majority of Pentastar V6 owners have great experiences with the engine. One of the things we can control is maintenance. Maintain your FCA 3.6L well and chances are it will be an excellent engine that you can enjoy trouble free for years and years. There are even a few cases of the Pentastar holding up to 500,000+ miles. How’s that for longevity?"
The writer then summarizes, "Reading about common problems is always scary. At least it is for us; suddenly we start thinking and assuming the worst. That’s the last thing we want when writing common engine problem posts and it’s especially true with the 3.6L Pentastar. It truly is a sound engine, overall. Reliable, efficient, smooth, and solid performance. There’s not much to complain about, but no engine is perfect.
"Some early examples of the 3.6L Pentastar ran into problems with the cylinder head due to overheating valve seats on the #2 cylinder. Rocker arms, cooling system parts, and oil pumps are among a few other well documented issues. However, we believe they’re well documented thanks to the 10 million plus Pentastar engines. The 3.6L FCA Pentastar really is a great, reliable engine. No engine is perfect, but there’s a reason so many Pentastar’s are out there. We believe that reason is this: it’s pretty **** good at its job."
Ok, well, this sounds like you may be the victim of a problem that was caused by the service department and not necessarily by an inherent problem with the engine itself. Hope you can get to the bottom of it.
