Hopefully this does fix it, we passed on the hybrid because of it.
It’s a little puzzling to me. The problem is a connector that can get shorted and the resolution is a software update. Doesn’t make sense.About 67,000 U.S.-market Pacifica Hybrids from 2017 through 2022 model years could have a problem that could cause the engine to shut down unexpectedly.www.caranddriver.com
Looks like they found the source of the shutdown-while-driving issue and have a fix! See the article for full details.
Indeed upon searching Chrysler Canada website it does show my serial # as being involved in the recall. We all go into the waiting game and hope nothing untoward happens in my driving this winter.I logged into my Canadian MOPAR account and it shows the recall for my 2021 PacHy already. You will be hearing more soon.
This recall is being done voluntarily by FCA, it’s not being ordered by regulators. Search your VIN on the Canadian Chrysker site.
As mentioned in the recall document, the fixed connector is not ready yet.It’s a little puzzling to me. The problem is a connector that can get shorted and the resolution is a software update. Doesn’t make sense.
I don't see how that part can short to the transmission housing.Here is the internal wiring harness from the excellent Pacifica transaxle teardown done by the WeberAuto YouTube channel.
I'm guessing there's a definition of "defect" somewhere that would be good to find. It also appears that not all the wiring harnesses are bad, otherwise a lot more vans would have had the problem. And there's no way for FCA to figure out which ones are bad, otherwise they probably would have done that as well. This remedy fixes the safety issue of a sudden shutdown, which then allows FCA to replace these transaxles like any other part that breaks.I don't understand, based on Title 49 of US Code, Subchapter II, section 30120 (49 U.S. Code § 30120 - Remedies for defects and noncompliance and section (a) listed below for convenience), how the remedy of updating software on the PIM / IPC is considered a repair, or allowed to be considered a repair, by the NHTSA. It does not fix the problem.
There is a provision in this section (section (e)) that appears to allow for individuals to petition the Secretary of Transportation to conduct a hearing to decide on if the manufacturer's remedy has met requirements.
(a)Ways To Remedy.—
(1)Subject to subsections (f) and (g) of this section, when notification of a defect or noncompliance is required under section 30118(b) or (c) of this title, the manufacturer of the defective or noncomplying motor vehicle or replacement equipment shall remedy the defect or noncompliance without charge when the vehicle or equipment is presented for remedy. Subject to subsections (b) and (c) of this section, the manufacturer shall remedy the defect or noncompliance in any of the following ways the manufacturer chooses:
(A)if a vehicle—
(i) by repairing the vehicle;
(ii) by replacing the vehicle with an identical or reasonably equivalent vehicle; or
(iii) by refunding the purchase price, less a reasonable allowance for depreciation.
if replacement equipment, by repairing the equipment, replacing the equipment with identical or reasonably equivalent equipment, or by refunding the purchase price.
(e)Hearings About Meeting Remedy Requirements.—
On the motion of the Secretary or on application by any interested person, the Secretary may conduct a hearing to decide whether the manufacturer has reasonably met the remedy requirements under this section. Any interested person may make written and oral presentations of information, views, and arguments on whether the manufacturer has reasonably met the remedy requirements. If the Secretary decides a manufacturer has not reasonably met the remedy requirements, the Secretary shall order the manufacturer to take specified action to meet those requirements and may take any other action authorized under this chapter.
Unlikely they are just going to replace every transaxle. The remedy fixes the sudden shutdown and that’s it. If you have this problem the transaxle will need to be replaced.I don't like it.
" internal transmission wiring connector which could short "
Does it mean that the entire transmission will have to be replaced? AFAIK Chrysler doesn't consider it field repairable.
So there is a connector inside the transmission that fails sometimes and causes the vehicle to shutdown. And the fix is to not really fix the problem by replacing a connector that has been known to short out. The fix is for the software to ignore the problem for long enough that you can safely pull the vehicle over. That translates to, the problem is rare enough and difficult enough to fix that we don’t want to do the right thing and fix it properly so we’ll just take away some of the danger involved with the failure and only fix the ones that actually fail.Unlikely they are just going to replace every transaxle. The remedy fixes the sudden shutdown and that’s it. If you have this problem the transaxle will need to be replaced.
Thank you for the great information in this thread! Knowing what's happening makes me feel better. I see how Chrysler might argue that the software change prevents the sudden stall at speed, and mitigates the accident risk. But for ourselves and our families on the road, having a cellphone, flares/lights, and other breakdown safety gear in our PacHy's seems a wise precaution.This remedy fixes the safety issue of a sudden shutdown, which then allows FCA to replace these transaxles like any other part that breaks.
I don't think anything I've seen so far indicates what the software change will actually do, beyond not killing the vehicle immediately. Perhaps a short time is two minutes to get off the road...or perhaps it's two weeks to get to the dealer. I think we'll just have to wait until we get official word from Chrysler or until someone encounters the problem after their software has been updated.Since the software change allows the van to keep running for a short time, I wonder why it can't be programmed to allow a "limp home" mode for a longer time? I've heard some transmissions in other cars provide that. It's not a question of preventing further damage to the transmission, since it's going to get pulled out anyway.
