Throttle body recall for 21-22 gladiators

[GWIZZ]

Z37 is the recall he was flashed


when’s your build date? Mine was December 21

They did the Z37 recall yesterday and it fried the PCM. The dealer confirmed it was the Flash on this recall and that this process fried the PCM as a result. Does anyone have the TSB to dispute? That would be helpful. The same experience is represented on the FB Gladiator Group I'm in. All have been related to this recall.

Can you elaborate more on this? Every search I've done only comes up with you reporting your experience. Not that I don't believe you, but I haven't found anyone else anywhere discussing it. And if it's only on a private FB group that's not going to be helpful to anyone.

I think it's important to get some fact out there before getting everyone worked up about it.

What is this reflash suppose to do?

No recall for my JTHA, build date April 2021....

Z37 - Powertrain Control Module Software. In the process the Powertrain Control Module was fried. The vehicle will not run at this point and the part is apparently on backorder.

3 dealers in the US have the part but will not sell it to my dealer. How long will this vehicle but undriveable? They said it could be months.

This is essentially a brand new Gladiator that I am paying for that I cannot drive.

I would not do this recall yet. The FB Gladiator Group I'm in has failures everywhere.

FWIW, I had my computer fried on 06.17.2022 while having the update. I had taken mine in for the CEL and when they tried the update the PCM got fried. I was told the same thing, that the part was on backorder. I got a call on Tuesday 06.21.2022 that my computer was to be in this week on 06.30.2022. So, hopefully you are not waiting months.

I’m December 21 as well I wonder if I should hold off, or make sure they have a rental on hand before they do it lol

Exactly. Seeing this stuff in a forum or a fakebook group is like being in a hospital and reporting back home that everyone in that city is dying or has cancer. (or is having a baby)

NEVER ever judge by FB or forums. The problem is greatly amplified and exaggerated on the web. It appears like if you do this, it WILL fry! But that's not even close to the truth.
It's crazy how the web has become how people learn how bad things are.
Fact is the huge majority of Jeep owners are not hanging out in forums or fakebook. In fact, as my son says "do you still actually use facebook? That's for old people". Even a recent TV show made fun of boomers still hanging out on fb. It was hilarious - the people the girl was talking to weren't even 40 and she was going after them with "I bet you still post on facebook" type comments.

Anyway.............
So you see 5 reports of problems but don't see the 5,000 reports it went well.
And of those who had a problem, the fraction of 1%, was it REALLY "Fried" (can't fry it, can corrupt it) did the dealer even try anything else or just say "woops, it won't start, PCM must be toast".
A flash doesn't technically fry or burn anything. It's re-writing non-volatile memory, like EEPROM.

Multiple possibilities:
What the dealer got for that specific vin was corrupted before it was "flashed" to the PCM
or
The dealer did not completely follow the instructions to the letter
or
Jeep has a corrupt template
or
The flash reset the PCM's security link with the BCM and RF Hub Module. There's a process where the PCM has to setup security to match. And if the request in the PCM is wrong, it ain't gonna start or do much of anything. The dealer needs to follow the processes to ensure they talk again after a flash if it doesn't just happen.

My bet - since no one has truly quantified any of this - it's all speculation made worse by the yelling and anger over it on the internet (where people gather to share gripes and anger) is that the numbers are truly few.
Unless someone counts individual instances, it's like a tiny fraction of all flashes that have been performed, and, of those, how many were due to what cause?

They performed mine yesterday while it was in for an oil change. Took a while though. Shows it should take 3 tenths of an hr but mine took well longer than that. Got the truck back and all seems good.

Before the PCM is flashed, there are certain things they need to do - or SHOULD do..........
1 is to check battery state of charge, if they don't meet a certain minimum, they are supposed to charge the batteries until they do.
May be other things, but the last thing they should do is skip the prep process - and ignore a low battery.

I'll give you a full report after mine on 7/5...

I have only conveyed what the dealership told me was the issue with the recall they performed. I have a dead Gladiator that is waiting for a new computer that is on backorder. I am not crying about it or attempting to mislead anyone but suggest that this might be worth waiting a bit to have this done.

I am not the only person with this issue. Trust me I would prefer that I had my Gladiator back in my garage and not the dealers. I would imagine that there are plenty of successful "flashes" but mine was not. There are many others that have experienced the same issue and have dead Gladiators.

I chose this forum to ask questions and state my issue to see if anyone had suggestions. My goal was not to get "everyone worked up about it" but to find resources that were clearly different from Facebook groups.

ShadowsPapa provided some good insight but may have indicated that I might be yelling and angry I guess. I was looking for the smart people to lend me a hand on how to address.

To those that provided insight, thank you!

And if my observations are right - the date of the switch isn't clean as Dave and others did some comparing of build dates and it wasn't a clean switch-over.

Yep. I have a September 21 build....gpec2.

 

[ecidiego]

I believe august 2021 and after have those

September 21, old PCM.

Wow...shame on me for looking for insight. I think the responses on this forum are far worse than any I have seen on a Gladiator Facebook page. You are correct I haven't seen the 5,000 that went right. Mine didn't and I was looking for resources away from FB that I thought could help.

Instead I got shamed for expressing frustration and looking for advice. You provided some good insight but telling me I'm basically an idiot wasn't necessary.
