In life, almost everything is a gamble, especially vehicles. You have to decide if your Patriot is a money pit or if you've had relatively few problems.
Consider, I had a 2008 Patriot that had a wiring problem at 210,000 miles. I debated putting out $1200 for a new harness on a vehicle with that many miles, but I also realized I hadn't spent much on repairs to that point, so I went ahead and got the new harness. I got another 75,000 miles out of it. I've since sold that Patriot to a friend and it's still on the road at 305,000 miles.
On the other hand I had a Cherokee that was a raft of problems at a mere 25,000 miles. Although the repairs were covered under warranty I was a sales & service rep on the road and if that vehicle didn't move then I didn't work. I lost patience with it and traded for an Oldsmobile that was among the best cars I've ever owned.
Like I said, it's a gamble. If your Patriot has been good to you this far, I'd stick with it. My Dad used to say that any car is worth one major repair; he also said the cheapest car you'll ever own is the one you own today. That's the same man that got rid of his Chevy Nova at 30,000 miles because it was a constant problem.
Finally, consider that the used car market is very expensive right now because it's nearly impossible to buy a new one. If you've got a dealer that's ready & willing to do the work, you're probably best to bite the bullet and get it fixed.
