Our 2017 Pacifica was two years old in December 2018. We are retired so we’ve been seeing the USA and have just under 59,000 miles on the van. In mid December 2018 a warning message appeared saying ”Service Electronic Stability Control”. We are away from our home dealer so we took the van to Tom O’Brien in Greenwood, Indiana. They are excellent people, and have treated us like we are their most important customer. BUT, after three visits they have not found the issue, and the warning message keeps returning. They have changed the electronic stability control component, the vacuum pump, and what I believe is the PCM component, and the warning keeps returning. We will return to the dealer for a 4th time this week where they will change a hose on the vacuum pump as the tech believes he heard a hissing sound from the hose when they changed the vacuum pump. Despite all of the electronic sensors that the techs can access which show various issues with a vehicle the system does not seem to tell them what is really causing the issue, and I keep returning hoping this week’s effort will solve the problem. The van has not stopped running nor does any of the performance seem different, but I don’t like driving down the highway not knowing if this warning message is going to trigger some automatic shut down or other safety issue. I didn’t purchase an extended warranty as a two year old car that had a sticker price over $51,000.00 should not have any serious failures in its first two years despite the mileage. I am in contact with a very helpful person at Chrysler too who is trying to assist. If anyone has had the same issue, and knows the correct solution your help will be very much appreciated.
