There were very few Pacificas that had the stall issue. There were threads that I've read that declared doom & gloom, definitely scary. However, over 200,000 2017 Pacificas are on the road & less than 1% had the problem, if I remember correctly. My Limited was built in March 2017 and I haven't experienced any of the stall issues, so far. Actually, I haven't had any operational issues with my Pacifica. A few weeks ago my phone dialed by itself and I really don't know how or why that happened, but it hasn't happened since. I can't even be sure it was the Pacifica messing up it may have been my cell. Pretty minor though.
And this is my 2nd Chrysler. In 2003 I bought a 2003 Town & Country Limited which now has over 225,000 miles. At that time I really wanted the 'new' Toyota Sienna, but the dealers were selling them as much as $5,000 over MSRP & I would not play that game. I got the T&C for $10K less than the Sienna would have cost me and decided I could fix it many times for that $10K difference. Yes, I was sure that the reliability would be awful. I read all the Consumer Reports warnings, but liked the look of the T&C so I took the chance. It turned out to be a great van with very few repairs.
But at 14 years old in 2017 I decided I needed to buy a new van & loved the look etc of the Pacifica. I mean, how much longer could this 2003 T&C run? It's a Chrysler, bad reliability - or so everyone keeps saying. I guess, with decades of people saying Chryslers have bad reliability it kind of sticks. But their reliability is far, far better than publications like Consumer Reports would make you believe. Look at how many older Town & Countries are still on the road. I expect in a few years I'll be saying this about the Pacificas.
So, most of the issues with the 2017 Pacificas have been resolved in the 2018s. As far as price goes, I think you should be able to do better unless there are other features you didn't mention. If you go to www.chrysler.com
you can click on build & price and configure what you want then it lets you search dealer inventory. If you look at the matches on the Dealer Site there are usually prices for what is in their inventory. It also allows you to see what Rebates may be available to you if you look at few different dealers. Good luck in your negotiations!
