Recall Notice 21V-028 [1/28/21]: Manual Transmission / Clutch Overheat Covers All 2018-2021 Jeep Wranglers Produced by January 22, 2021

[PierreNL]

Ordered mine in November also and no news from dealer yet..

Just got a call from my dealer today and he gave me the Vin and expects shipping at end of April and will call me back when on the train .
He said I am lucky because they are going to receive only 10% of the wrangler they ordered for the dealership and the few ordered by customers this year.
There is a shortage of V6 and microchips,so they are keeping the V6 for the Rams and manual wrangler.
All jeeps in dealerships are automatic and 4cyl.
They never mentioned the clutch issue.

There is no temperature sensor in the clutch assembly, so the reality here is that the software reduces torque if it believes the clutch temperature has risen due to various parameters it models.

It has no idea if clutch slippage has actually occurred or what the temperature of the clutch might actually be, it''s all purely theoretical.

It knows if the clutch is slipping based on engine rpm, the current transmission gear and the drive shaft/wheel speed. Based on the amount of slippage, it will make an educated guess about how much heat the slippage is generating.

I ordered my manual JLR in mid February right before the recall patch was issued. I got a VIN the next day and it just shipped. Incredible turn around time for the build in the middle of a recall and pandemic. I’ll update when I receive it. I’m have zero concerns with the recall patch. Everyone needs to chill and be happy with their vehicles.

For all we know every transmission has the same type of software boundary cases programmed in them.

Perhaps automatic, but one of the things people have long liked about manuals is they were “dumb” - gears, a lever and a clutch, that’s it.

It’s not available to dealers, yet. They are applying it at the factory for ‘21s. It shouldn’t be long before it’s available for the rest of us.

It is available for 2021 models. 2018-2020 models got separated into another campaign, Y07. The flash isn't ready for Y07 yet.

The fact that the 21 flash is separate from the 18-20 flash again makes me wonder if that addition of showing the current gear on the dash displays will only be for the 2021s.

Is there an estimate of a time when the Y07 flash will be ready? My 2018 JL failed MA emission testing due to the EGR and O2 monitors not entering a ready state and I only want to make a single trip to the dealer for both the emissions and clutch recall. I have about 30 days left to repair the emissions issue.

i am very afraid of some piece of metal coming through the floor boards and killing me.
I've read that this is a possibility?
I still don't feel a software patch is a solution to a defective part.

In this case it is, as when the software detects the clutch is heating (which causes the issue) it will reduce engine torque so the clutch can't overheat.

That having been said, if someone is injured in the future in a vehicle to which the patch has been applied, that will be a really interesting lawsuit to watch.

Does anyone know of any other manufacturer producing bad clutches for 4 years straight in their vehicle line up?

43,000+ on the road with no injuries. Nothing to be “very afraid” of... much more likely to be injured or killed in a wreck. You’ll be fine.

I do not have an ETA yet but I know it will most likely be longer than 30 days.

I am still confused that anyone thinks they can fix this problem (if it is indeed an everyday regular use issue) with a software change. From what I've read on this forum, the rumor is that these software geniuses will do some kind of reverse calculation from what the traction control software does and deduce that if things are not rotating as they should, then s/w cuts back on power/torque. To get that kind of resolution from sensor and have it reliable for 10 years sounds a bit unreasonable. And then, the V&V (verification and validation) must be really complicated to make sure that and traction-control don't do battle in the software domain. I guess that's perhaps why the s/w is not available yet.

Would you not feel that much slippage (if you are not causing it)? And if you are causing that much slippage, perhaps an automatic is in your future?

Would seem to me that using non-explosive parts in their drivetrains is the 'right' solution. Until the s/w is available I will keep driving my IED (the proper way so it doesn't explode ).

I just had the recall software update done yesterday. The Jeep drives the same. The 2 main things that I have noticed are that the gear is now displayed and the ESS no longer seems to do anything. I even tested it by idling in a parking space after driving to work today. I am happy about it, I never liked the ESS. Has anyone else noticed this change with the update?
