Not sure if you guys read up on my little issue with this problem. Here is a link to a thread that some people were following.
**** New Section for Supercharger issues ****
I started having a "loud" bearings issue after 120 miles. I reached out to a list of FCA execs, as well as FCA's public media relations about these issues. I got a call the next day. In short, FCA was sending out a replacement SC, but the tech from FCA cancelled the order immediately, saying that a replacement will not fix the problem. So I emailed the group back and got a call back the next day again. I had the woman from the FCA exec office on the phone and a man named Carey, that had a technical background at FCA. He did inform me that some bearings in the SCs were reaching their audible tolerance, and that's why they would get noisy. He also pointed out that there have been zero failures due to this. I was trying to gather all of this in, as he explained this to me. So your story about them telling you about another SC replacement is consistent with what they told me they would be doing. They would start taking care of the current issues, then start back to the oldest problem cars, and get them back in for another SC replacement. It seems that they, or rather IHI may have a working SC now, maybe. FCA sent one of the first "new", probably refurbed IHI SCs to my dealer. The dealer didn't even know it was coming until the day it showed up. Anyways, they called me up, I dropped off the car and after a couple of days I picked it up. I was glancing at the paperwork and talking to my service advisor. The part number ends with the latest AB part, but the FCA engineer on my case, assured my service advisor and manager, that this is not the same AB SC that was originally ordered for me, as he cancelled that. Of course I get a follow up call from the FCA exec office the next day to ensure everything was completed to my satisfaction. I basically told them time will tell. I lastly emailed back the exec members and thanked them for their time and effort, and for the personal assistance and insight as to the issue of these SCs and that I will follow up after some time. So far over 500 miles on the new SC and all good.
