I bought a used 2018 Pacifica L that had been a rental, from a dealer with 3K mile/3 mos warranty. Just after the 3K miles, I had familiar noise from the driver side front. Turns out to be the lower control arm and needed replacing, tech recommended also the passenger side. (I had just recently had to do this same service on my 2004 Subaru Outback which had over 220K miles on it. I traded that car in for the Pacifica a few months later). Spoke with Chrysler re such a repair being needed at 40K miles. They said to get service done, pay for it, then submit for some possible reimbursement, nothing guaranteed, so am doing that. But I'm just curious if anyone else has had this problem and at what milege. Thanks!
