I have it for my wife’s stelvio. I don’t think an independent shop can do warranty on the extended plan. From what I understand the mopar plan is an extension of the factory warranty. The one on my wife’s car includes all same things the original one does. Towing, road side, etc. I got the longest one available. 8 years, 100,000 miles. We bought the car a year old with 29,000 on it and paid 3200 for it. The 2017, 2018 and some 2019’s are having oil pump failures. Which is what lead to the engine replacement. Got a new oil pump at 33,000. After that the engine was never right. All my complaints about it were covered under a bulletin that said it was normal in that production range of engines.
An extend warranty is worth it. One major thing goes wrong. Its paid for itself. My wife’s 2019 stelvio got a new a new engine assembly at 44,000. Imagine how much that would have cost 6,000 miles later. Now at 75,000 the trans is shuddering when it shifts. Progressively getting worse.
