With it being a Jeep and my luck I’d say it’s probably going to be a computer problem.
1) wheel speed sensor replaced under warranty. The rest out of warranty
2) oil cooler
3) thermostat
4) water pump
5) transmission control module
6) crankshaft position sensor (easy repair but what fun when it would shut down on the highway)
7) alternator
8) replaced left side rocker arms when I got the tick.
Only ran 5w20 Mobil 1 its whole life. All other fluids and maintenance (plugs, filters) way ahead of schedule. At least it’s easy to work on.
