I have been driving Blue since 2017 and She has been a very good girl. even protected my family in a pretty severe collision in January. However, Over the Memorial Day Weekend, we noticed Blue was making some loud grinding noises while accelerating and decelerating. No Codes or check engine lights. Actual driving performance was not affected at all, just a horrible racket!. I take it to the dealership, and I'm informed that the Hybrid Transaxle is toast and needs to be replaced. $11,000 to do it, because they cannot install any rebuilt or replace internal parts to the transaxle, it has to be replaced as an entire unit. So that's insane.... I have been looking in vain on how to procede. Does anyone work on Hybrid Transmissions? How do i get this fixed? The 2017 battery has 10 year/100,000 mi warranty, Powertrain has 5 year/60,000 Mile warranty. This car has 95,000 miles on the ODO.

Well, I have to say that is unfortunate. It is a new design for Chrysler and what you are experiencing sounds exactly like what others on here have noticed when a replacement under warranty was needed. I have not physically seen one apart other than on you tube and needing a replacement Hybrid transmissions are not that common.You may want to bite the bullet on a new one or research how much for one from a junkyard is. Most reputable yards like LKQ will offer some warranty. If I was you, I would make a decision to keep it or not. If you like it and plan to keep it, go for the new one (warranty from Mopar I think is 3 year unlimited miles (you may want to check)). If you plan to dump it in a year, go used.

What corner was the van hit on?

Insurance usually covers issues that creap up for a year or so after it was repaired. Might be able to get your insurance to cover it.

11,000.00??? I think you are getting ripped off.

Google the part number, multiple prices from several resellers. Those are some crazy labor rates they are charging you to hit 11,000.00.

Not much more expensive than a NEW traditional automatic transmission.

Hybrid Transaxle Assembly - Mopar Part Number: RL359946AC Price: $4,801.37

Here is the HV battery if you are curious.

Having been burned in the past by Chrysler's transmissions, it's stories like this that have me considering an extended warranty or maybe only keeping the Pacifica for a few years to avoid stuff like this.

I've had Chrysler products for many years and have found one thing to be true...I never buy extended warranty's because when I've run into a situation like yours I've called the help line. I try to do a little research ahead of time to discover how many others have had a similar problem because I know I'm not the only victim. I explain to them my disappointment in what I thought was a quality product before I purchased it but I NEVER get mad our threatened to never buy one again...once they hear just disappointment on your part they'll listen. I also let them know I'm not expecting something for nothing...just fair treatment. Usually they'll take the issue under submission and go up the food chain for a decision...at the lower level they can't help you. In every case except one they've done the out of warranty repair for a 100.00 deductible...once I had to ask for upper management help and they also did the repair for the same deductible...don't get mad just be insistence. That's helped me in at least 10 repairs. I currently own a 2018 Pacifica Hybrid-2013 300-2008 Caravan and a 2004 Ram 1500...Let us know if that helps--Hybrid owners seem to be like a family.

I've watched a video on the tear down of this transmission. The only thing that looks like it could fail is the sprag clutch. Surely you can get a good shop to rebuild the unit for way less money. I've personally rebuilt a GM TH350 transmission (and I'm not a mechanic). The CVT in our hybrid Pacificas is a piece of cake by comparison. It doesn't even have any clutch packs.

(Si-EVT) It's not a CVT. Those are complete junk due to high failure rates of the steel belt breaking.

It has six torque limiter clutch packs in the Si- (SIngle Input) of the Pacifica hybrid.

I presume you meant Labor Day last weekend and not 3 months ago, yikes! o_O

Anyway, where's Blue now? At the dealer? Are you using it?

And what do you mean by loud? To me, loud and horrible racket are way different. If you have Blue then can you post somewhere a video of it making the noise? If possible at acceleration, cruise, deceleration and "idle", in both electric and hybrid modes. Or at least tell us when and where it it grinds and if there seems to be a pattern. Does it happen when the gas engine is on? When it's off? Hot? Cold? Fast? Slow? Etc

It could be something as simple as one of the internal oil pumps gone bad which seems relatively serviceable.

I believe it is classified as a CVT, but either way, the sprag looks like the only thing that will wear out. The torque limiting clutches shouldn't slip under normal circumstances. It should be an easy fix, certainly not a $11k job.

It's an EVT.

I don't think it's an issue with the sprag since the OP says it drives fine.

Wonder if the parking paw is not fully disengaging and/or damaged and grinding against the lock ring as there have been various reports of parking paw issues. This would be on the more extreme end if so.

When I watched that transmission tear down video, my thoughts were that it looked simple and even Chrysler could build it reliably. Was I too optimistic? I'm trying to think what could go wrong. The Motor B is spinning at more than 10000 RPM when driven fast, could one of its bearings go bad? That should be a repairable with independently sourced bearings, although most shops would be afraid to touch this transmission

I doubt the dealer has a clear understanding of what's gone wrong if it really is inside the transmission. Also, the CV joints in the axles can cause grinding noise under load so asking specifically if they have checked the axle joints(and wheel bearings) is a good idea. These have been more of a problem with the gas versions.

Some other thoughts for what it's worth:

A second opinion from an outside shop may be helpful.

Finding and installing a used transaxle is something the dealer should be willing to do (no guarantees though) if the axles are not the problem. The dealer quote should have identified labor and parts separately. I would expect labor in the range of a couple of thousand.

Finding an independent shop willing to take on the work is the next step if the dealer won't work with used parts. WeberAuto on youtube is associated with Weber State University and they train mechanics which would presumably be for independent shops. Maybe they know someone they've trained or can point you to a trade association which lists independent shops. Shops which work on the Prius are set up to deal with high voltage safely. They should be willing to work on a Chrysler. These transmissions are similar and, compared to typical automatic, much simpler mechanically. Maybe this can help. https://www.thehybridshop.com/

Good luck & please keep us up to date on what you found out.

I just dropped off blue at our local Hybrid Shop in St. Charles appropriately named "Sparks Tire and Auto". They didn't even flinch when I mentioned it was a hybrid. Hopefully I'll get good news!

Just got a call from Sparks... They are asking for $9,000 to do the repair, and they need half up front to do the work. Yikes...

As an aside, We have been escalating up on the Chrysler Cares side, and might get a response tomorrow,

If not then... Who wants to buy a used Pachy?

Can you post a video of the noise?
