After 5 months of owning my first 2017 brand new Durango, it's dash lit up like a Christmas tree so off to the dealer it went. A few days later they said 'good as new', and I didn't even get 3 miles from the dealer before the same thing. They had it for 5 weeks and still didn't know what was wrong, had replaced almost all of the wiring harnesses / etc. and still couldn't get it to function. Bought back as a lemon. So, good luck if you buy it. If you really know cars and can troubleshoot and repair them better than the dealer, go for it.
Otherwise, seems like you are buying a lemon without a warranty.
