It's funny, I am now annoyed if I have a service due on my ICE vehicles. Ugh, oil change.
Pros: no need tire rotations
Cons: ugh, oil change
I got a Mopar thermostat from the dealer a few months ago. Works much better than the previous two aftermarket units
Pros: works much better
In case anyone else comes across this post, it was the aftermarket thermostat. I managed to get a hold of a mopar one yesterday and the gasket around it was just slightly larger than the aftermarket one and needed a little bit of resistance to seat it. Now my truck is getting up to temperature quickly and working great.
Pros: truck working great
Cons: aftermarket thermostat bad
I replaced the thermostat in my wifes 2014 journey with the V6. It was an easy and straight forward job.
Pros: easy and straight forward

I highly suggest only getting genuine mopar. Myself and others have had issues with the generic part store thermostats that were fixed by using mopar.
Pros: genuine Mopar fixed issues
Cons: generic part store issues
Cabin filter doesn't matter. Air filter needs to be mopar 53034051-AB or fleetguard AF27684.
The older mopar 68517554AA, wix 46930 and most other air filters have glue strips on them. They've been known to throw check engine lights cause of the glue strips on them.
Cons: glue strips, check engine lights
Part number: 53034051-AB
I just bought one off RockAuto. I have to overhaul my entire coolant system and through some searching on this subreddit I saw a lot of people saying the Motorad brand kept failing after a few months. I didn\u2019t want to risk it so I opted for the Mopar thermostat from RockAuto for $35.
Cons: Motorad brand kept failing
Replaced the original starter with Mopar OE last February after it went out with roughly 106,xxx miles. Here we are December and it has failed again.
Cons: failed after short time
Mileage: 106000 km
Stick with Mopar thermostat. I went off brand and it didn\u2019t work correctly.
Cons: didn't work correctly
Vehicle:
Fiat 500
