I'm trying to get any new info on this thread related to "limited performance-service fuel system" and the related TSB 18-049-23REV A.

My 2022 JLU has no performance issues but message appears on harder deceleration. I'm just out of warranty and understand that dealers don't have to perfom TSB at no charge. Have folks found that reprogramming the PCM takes care of this message?
I've had the TSB done, and have still seen the error message after. On harder deceleration. No check engine light or stored DTC's, I checked with Jscan and absolutely nothing shows up. Personally, if you think you are going to have to pay I don't think it's worth it. I think it's just a bogus software programming issue that affected the 2022s. It does not seem to cause any drivability issue or any real issue.

This is correct. It's just shitty software with no real performance concerns. I haven't had one come into the shop in awhile for this, but if it's just limited to the 2022s that's probably why. There was like 1-2 flash updates that was supposed to help with it.

Thanks for confirming. I had the initial flash , i.e. the TSB mentioned earlier in this thread, but have still seen the error message pop up after. I figured since there is no check engine light or no stored DTC's, a dealer could not even confirm the issue anyway.

I’m getting this on a 22 Rubicon that I bought used. I need to get it in for the TSB I guess.
