Is it that it is not picking up misfires that actually happen, or is that it is giving false positive's, or both, or something else?

At any rate, I think ShadowsPapa will be happy to see this "misfire" thing.

Is this the same recall that came out about 8 months ago?

Old one, applies only to 2020.
I now have a 2022 (and the misfires are very real)

Here is where it was discussed about a year ago here -

I just bought my 2022JT a month ago. Last Friday I got the check engine light. It was the miss fire code, I dropped it off at the dealership Saturday. Picked it up Tuesday. They preformed the new software and alignment of timing.

I lifted and installed 37 within a week of purchasing it. I was very unhappy with the drivability of it and was preparing to regear.

After the software replacement of the dealership it is night and day difference in Preformance. It went from 14 to 16 mpg and now goes to 7th gear.

and alignment of timing.

???????


The 2022s are under different TSBs (or maybe it's an RTT, can't recall now)

Relearn cam crank sensors.

Relearn cam crank sensors.

They must have wanted to force a relearn..........
They'd do that if the Camshaft and Crankshaft relationship to be relearned after certain parts were replaced or to account for wear, etc.

Interesting... Maybe this only affects certain build dates? I haven't received any calls or notifications at all

The one that the OP mentions is 2020 ONLY.
There's something different for 2022, but it's of limited impact. Mine, a June build, has zero recalls, or anything else for that matter. I had my dealer check my VIN against all known recalls and RTTs. It's clean.

nt for 2022, but it's of limited

Yeah sorry to clarify I was asking about the 2022 version that you posted about.
