I'm not sure that's true. TSBs are usually only handled when customers complain about the problem. For instance, there was a TSB for my truck, the fix for which was to replace the 3-leaf leaf spring packs with stiffer 4-leaf packs, replace all the oem shocks with better bilstein ones, and to perform a four wheel alignment. After that TSB came out, new trucks did not include the fix and dealers sure weren't performing it. The fix would only be performed if you could prove to the dealer that the truck could not handle the posted payload capacity and that it had a "rough ride when loaded." That's a different company than Chrysler, I know, but I don't think any car company is obligated to perform TSBs. Now if Chrysler wants to be sure to take care of them before the cars are delivered, then that would look great on them and I applaud them.

I believe that was for Recall J33 "Instrument Panel Top Cover" which had an issue related to the passenger air bag.

The dealer site provides a notice for unperformed recalls and Rapid Response Transmittals when a vehicle VIN is brought up for service/warranty work. TSB's are not listed on the report as they are typically not "urgent" or safety related. There are dealers who will check for applicable TSB's before a vehicle is delivered to the customer. It's in their best interest as they get paid for fixing TSB issues while the vehicle is under warranty.

dubwarren, is the rumble entirely gone? although better, mine seems to persist in auto mode from time to time, sometimes still quite noticeable at WOT. i too had the update.

very slight rumble persists. Didnt notice until this morning. Have you tried sport mode? Im going to switch to sport mode on my next drive to see. It only seems to happen during hard driving for me or while going around a sharp curve. It seems like the update made a difference though. i can give better feedback after a few days i think.

EXACTLY! hard driving or exiting a curve for me too. as far as i can tell it will not happen in sport mode, i've been trying.
if it does, it is really really faint. the reprogram was an improvement, but not a complete fix. i'll live with it for a little while, but i hope there's a permanent, all-modes fix.
