Just my experience - but my 2019 JLUR has been flawless - only have about 9k miles on it which is low mileage - but not one issue I've experienced yet. 3.6L totally stock everything. Zero complaints here but I feel for folks that have issues - can be incredibly frustrating when you spend that...
Dalema - I bought a '19 in July - Sting Rubicon and my 15 yo daughter and I have been doing trips in it - it's been awesome for bringing us even closer together. She loves riding in the jeep - and yes she's already laid claim to it next year... they dream... Hope you continue to enjoy yours...
