Iíve had the same transmission issue that many, many others are reporting - at about 14 mph, it fells as though the car canít find the next gear, the car revs but hesitates until it finally jolts forward so violent that it fells you were rear-ended by other car. Makes for very dangerous driving on any kind of winding road or road that has snow. Iíve had the issue since Ove 2017. I had the car for over one year with no problems and then as many others report, I too suspect my car was updated at the dealer and now has this problem. I brought the car to the dealer man many times. At first they said they reflashed it and problem solved. I eventually got Chrysler customer service involved. The dealer had the car for two weeks and Chrysler paid some $600 for my rent car reimbursement. The rep closed my case but I still had the problem. Now I escalated to someone named Audrey at ďEnhanced Customer CareĒ and they finally had the dealer Teterboro Chrysler in Teterboro NJ place a data recorder. After a few weeks of driving and recording the problem, returned the car to the dealer, waited for a few weeks only to learn that the dealer could not figure out how to upload the data to Chrysler. After another few weeks, I received a telephone message from Audrey that Chrysler determined my car was running as it should be and they are closing the case. I specifically asked for a new transmission as it was under warranty, and Chrysler refuses. How could they get away with this? Iíve purchased only Chrysler cars ever and never had this terrible experience where a car is dangerous to drive yet nothing is done, at least replace my transmission as itís under warranty. I think the only way is for several customers to get tighter and hire a law firm to file a class action law suit.
