I bought a 2019 Jeep Grand Cherokee Altitude last year and love it. I've had 2 previous Jeeps and so has my wife.
My Jeep had an engine start/stop feature (ESS) which shuts the engine off. I hated it (especially when the air-conditioning is on) and saw on a Jeep forum that a guy makes a switch that plugs into the diagnostic port or under your seat. It basically remembers what button you have pressed last. Worth every penny.
