I have a 2017 Jeep Patriot Sport 2.0L. My issue is when from cold start the vehicle vibrates like a massage chair while in park and in gear. I understand the vehicle is warming up and it even does it at normal temp. It feels worse when you turn the A/C on. I had all motor/trans mount replaced but didn't do anything. Could it be the torque converter that's causing it? Anything helps.
