When I took my Hybrid in for the recall I also asked them to look into a knock/clunk that was most noticable under moderate acceleration or deceleration at low speeds. The dealer was unable to diagnose the problem (I own the only hybrid they've sold and this is the first service). They waited until today when a regional service tech with more hybrid experience was visiting. He thinks it's the transmission but is not sure if the noise is normal or not. They've actually sent recordings out to Chrysler and are waiting for feedback.

Has anyone else experienced similar symptoms and have you done anything about it?

Thanks.

Update: Got a call from the dealership and they state that records show a fork in the transmission was replaced during production. They believe this is the root cause of the symptom. They are not allowed to disassemble and repair the transmission, only replace it. Further, they are not allowed to order the transmission as it is a "restricted" part. Chrysler has placed the order for the transmission. They will update me on Monday of the status of the order.

It's been almost 4 months waiting. I guess I can wait another week or so. I do still have the free rental loaner.

Interesting, an issue with the transmission after that whole mess with the batteries. I had hoped to replace my gas Pacifica with a hybrid in a few years after the kinks got worked out, but the list of kinks appears to be growing by the day...

Are you talking about something like a gear grinding or engaging? On the Limited (gas), if I'm coasting where the engine isn't in load for deceleration or acceleration, and I tap the gas, I hear a "thunk" or grinding sound like a gear sound.

What was the resolution to the transmission thump? My 2018 gas has been doing this for awhile as well. Haven’t had much luck with dealerships figuring out how to fix stuff.

I brought my 2018 Limited to the dealership several weeks ago with similar knocking sounds/symptoms and they reported to me that they're replacing the entire transmission with a new one under warranty. This is the second time the van will be in the shop for several weeks since I purchased it in April 2018.

Update: transmission finally replaced after 20 days out of service. Road-tripped 700 miles over Labor Day and the vehicle appears to be functional again.

Fingers crossed.

I have a knock sound coming when internal combustion engine comes on. It's really difficult for me to have it taken to dealership since the dealership near me has been telling me for over 5 month now that their Hybrid Technician has left. Next closest dealership is about 20 miles away and is booked for long time for hybrid appointments. I am nearing 10K on my VAN and starting to find out few bugs and issues with charging. Hopefully dealership resolves their technician issues otherwise i might end up regretting getting this Van.

Please try to describe the "knock" more fully - is this a low speed down shift? I've read this is an issue (happened to car and driver during their long term test) and I'd like to know if it's a symptom of future failure. Mine does the low speed herky jerky downshift sporadically.

My 2018 hybrid is experiencing the same issues after getting the transmission replaced. The noise didn't appear immediately, or it wasn't apparent right away. I noticed it when I was driving in the neighborhood at lower speeds and had to go on and off the gas several time in a row. The noise was pronounced and you could feel the clunk each time you applied torque. It seems to have gotten worse and I can now hear the and feel the clunk at speed. My local dealer handed it back and said they know there is a problem but without a hybrid tech can't touch it. After several hours I found a dealer an hour away. It took me 3 visits one taking almost 2 months to replace the transmission. I was told the first dealer never completed the recall. The one to prevent the catalytic converter from catching fire and that adding to my worry. I just don't know what to do. I love my van, I love that's it's hybrid and I love telling people about how awesome it is. I just need Chrysler to step up and work out something with me so that feeling continues. Fingers crossed.
