Premature Engine Failure

7345 Views 23 Replies 14 Participants Last post by  PacificaMinivanFan
My 2017 Pacifica with 82,000 miles started with a message when I turned the van on indicating the "automatic off/on system was unavailable." This went on for 2 days until the engine light came on. Took it in to the dealer and was told a "misfiring" code was on, turned out to be a coil that needed to be replaced. Was recommended we change the spark plugs too. Within 24 hours of these these repairs, the "automatic off/on unavailable" message was back on and a day later the engine light. Took it back to the dealer and was informed one of the spark plugs had blown and essentially we had premature engine failure. Has anyone else experienced this? We are set to pick up the car this week, but I am wondering how common of a problem this is with the 2017 mode. Thankfully we had purchased an extended warranty when we bought the car, so it is covered, but this does not bode well for the longevity of the vehicle.

Is it this?

Similar events unfolding for me too. Bought my 2018 60-days ago and the start/stop pretty much was always "charging" (worked a couple times after some 3 hr trips). Drove it 4 days ago and CEL came on with the message start/stop needs servicing. I went ahead and replaced the AUX14 battery for the ESS and pulled the CEL code at Autozone. Code was P0302 "Cylinder #2 misfire". The new battery didn't resolve the problem, still had a very rough idle, loss of power and CEL kept blinking. I took it to the Chevrolet dealer that sold me the van and holds a 90-day warranty. After they pulled the same code (and no further diagnosis), they said a Chrysler dealer needs to fix it. They're claiming it'll be covered by Chrysler's powertrain warranty, I reckon its ignition system related and want it repaired under the more comprehensive 90-day warranty.

Good luck with that fight. I'd make sure to insist the Chevrolet dealer handles it because its under their 90 day warranty. Dont let them pawn you off to Chrysler.

Also might be time to consider an extended chrysler warranty. :)

Bottoming out how my problem was resolved: TLDR; At ~24k miles, bad coil pack caused sparkplug to fail. Replaced both and then reset the ECM.

Looks like this is a common problem and I might just bring the tools and parts to replace on my own if I go on a long trip with this car. I'm just not keen on having my torque wrench bounce around in my car all the time.


The Chevy dealer I bought it from, whom was responsible for the warranty, was inept at doing anything other than using the OBDII scan tool to pull the same code as me. I had them bring it to the Chrysler dealer 2 miles away and handle the business-2-business charges, which worked out well. Even though the Chevy dealer wanted me to bring the car over, the contract on the warranty said otherwise and I refused. The Chevy dealer relayed a message to me saying Chrysler looked at it, replaced plug and coil pack but was still having problems so they were going to look at the fuel rail. Eventually when it was finished, Chevy said they just had to "do an adjustment" after replacing plug and coil pack. That immediately left me with more questions because you shouldn't be adjusting the gap to these new spark plugs (and who doesn't check the gap before installing them?!), nor do I know of a way to adjust the coil pack. I called the Chrysler dealer and got to the bottom of it and he said the coil pack going is a common problem and replacing the spark plug and then reset the ECM is standard operating procedure. For a car 'professional' at the Chevy dealer, he sure knew little about cars and was horrible at relaying communications.

I have had similar problems, except for cylinder 5. Replaced the spark plugs, worked for a while. Broke again, replaced the coil packs, worked for a few days. Broke again. Just found out there is a crack in cylinder 5, coolant has filled that cylinder, the engine is a loss. That will be $10,700 please. Ugh. Done. Taking the loss and getting the **** outta this thing.

How many miles on your vehicle? Any powertrain warranty left?

I'd replace the plug or plug and coil pack, whatever it takes to get it running again and then rush to a dealer and trade it off.
How did they determine that the cylinder was cracked? Head gasket would be first choice and while they have heads off then inspect cylinder for a crack.
yep, Im basically in the same boat now. ess light the engine light. cam shaft issue, engine out of time 66000 miles. the dealer aaid 50/50 shot that the extended warranty will cover it. Im absolutely sick over this. My first and last Chrysler vehicle
Also in same boat, 2017 at 63k miles. Misfire in cylinder 3, spark plugs covered in coolant. My mechanic suspects a head gasket leak, but was shocked it would happen in a car so young (never overheated, no other mechanical issues) Told me to take to dealer to confirm and hopefully they would cover it. They want $5300 just to take the engine apart to see what is wrong, plus whatever it costs to actually fix it. 3k miles outside of warranty so Chrysler denied my claim. I am furious. My first and last Chrysler.

I am experiencing an identical set of issues. What did you do to fix? Was the entire engine replaced?
I am talking to a very good class action attorney who asked me to check here who would like to join my case. Anyone?

Filing a class action suit against Chrysler, Autonation et al, so looking for victims of these lemon cars.
