I live literally less than 285 feet from the shore line and have zero issues with paint bubbling. It’s nothing to do with the coast and Jeep warranty could care less where you live, lol.
Take it back and get something else. Go to a new dealer, the one your at are morons, the stabilizer is not and will never be the culprit of Death Wobble.
Every 2.0 owner I personally know has replaced their coolant tank. They leak from the seams. It’s typical for it. Cheap easy fix. Just make sure your specific repair shop know that the coolant system has to be vacuum-bled.
In regards to the “engineer” side of the story it was specifically 28 of them and those apparently were plant engineers. Not R&D vehicle peeps. According to other news outlets.
No burping on these engines, they are vacuum bled systems. Just top off and watch it periodically. My 2018 and 2019 2.0 both had severe coolant issues so I sold them and got the 3.6. But I did enjoy the 2.0 when they worked.
