My 2019 wrangler has the same exact issue with the same mileage 778. I get a service Start/Stop system message then the check engine light flashes with three codes P0171, P0300, P2096. What is the production date on your vehicle? Mine is 12/18. I noticed the lower gears sticking/shifting hard. When I stepped on the break it decelerated and then bucks before it comes to a stop. I have a manual transmission.Only 750 miles and its back in at the dealership.
For the same issue
P0300 and P0171
First time they replace O2 Sensor 1 Bank 1
Symptoms included
Auto start stop disabled
Check engine light
Fuel Milage goes to crap
Idles rough
Shifts wrong (sticks in gear)
Service advisor says they might need to call up the line to get it investigated.
@JeepCares has this come up yet?
