2015 non-cvt. Hey guys, just wanted to share my experience with the patriot so far and hopefully be helpful to anyone else with a similar issue. I bought my pat used a couple months ago. I noticed that the trans seemed to be jerking and having trouble shifting frequently. Took it to the dealer only to lose my car for the week. They found nothing smh. I read a few threads on here and decided to change the spark plugs. Good as new, no jerking or engine hesitation at all whatsoever. Accelerates great now!
