So, got the engine module recall notice on our Pachy 2018 and immediately brought it in to our local dealer. The car has 10000 miles on it, about 2500 hybrid, rest all electric. The dealer applied that recall software update and another one on our entertainment system. It took about 2.5 hours for both, which was expected, so all good there.

We get Home and plug in the van to our level 2 charger as usual, all good. Normal clicking sound and we leave the car and garage. Later as I walk into the garage area I can hear the car sounding like it is on, whirring real loud, and notice the garage is much Hotter than usual, as if the car is on. It wasn’t of course. I saw the first 3 or 4 charge lights on the dashboard blinking as normal thru charging. By the time I got my phone to video the car sound it began to subside. I did however check Uconnect app on my phone and it said it was 74% charged, and of course still going.

Has anyone else run into something like this? It was loud enough that I thought, is this car going to explode?!?

Any info or advice, would help calm us down.

Wow. That’s really loud. Sounds like some fan is trying hard to cool the overheated battery/ engine.

Yep! The really strange part is it’s at about %75 of the charge. My wife is saying it was at about %12 as well. She’s getting scared to drive it now. Also, we never had this prior to the software updates.

I think that is normal. I get that noise all the time when I charge with our level 2 charger in our hot garage here in Phoenix. It needs to cool the battery while it is charging when the air temperature is high. There is general agreement that there is a fan that will come on to keep the battery cooled. I suspect, but do not know for sure, that it is also turning on the air conditioning compressor.

I hear what you are saying, but how is it that since November 2017 with all the chargin* we do multiple times a day, we have never had this happen, but yet after the software updates, all of a sudden this problem happens?

I am waiting for a call back from our local Chrysler dealers service adviser this morning.

Anyone else experiencing this?

I have never owned an electric vehicle but is the charge rate the same as before the software update. I know with batteries if the charge rate is increased the energy level (ie heat) is increased.

My fans cycle off and on during charging, especially when it is hot outside... My garage also gets warm.

I've got a 2018 as well, purchased last April.

Frankly, if the cooling system wasn't passively cooling the battery pack that means the batteries are getting cooked (and getting their lifespan significantly curtailed). I've not thought anything of it as Teslas will also do the same thing.

Well, charge rate time has not changed it is still the same.

I too have heard the fans go on and off in the past, but never to the extreme we are hearing now. I am a little disappointed in our dealer, as we STILL have not gotten a call back since yesterday when I left a voice mail for our Service associate at 4:40PM.

Another possibility is the battery pack is defective and a cell or two are overheating while charging.

Timing just seems too coincidental, as it was fine before the Software Update....could it happen, I guess so...but what are the odds with all the other strange happenings on these cars.

Also the faster the charge the shorter the battery life. If time allows, Level 1 is best and may not heat up as much.

My guess is that the update made cooling more aggressive to address issues that Chrysler tracked down to overheated batteries, but just a guess.

FYI I'm trying to reply to your PM but I'm getting this message:

ChryslerCares has exceeded their stored private messages quota and cannot accept further messages until they clear some space.

Could forum admins extend their private message quota?

It could be by design with the software change. Might be in place to better protect the battery? I would call Chrysler cares to open a case to get an answer from an engineer. Hopefully they can get you one rather than default to "bring it in".

I opened up a case with Chrysler cares via this site, and also went ahead and scheduled to bring the car into the service center at the dealer near us. Assuming they have a way to monitor the charge/sound maybe via diagnostics, it should reproduce the issue. You may be correct with the change by design, but for someone at Chrysler not to be able to answer that question, does not give me comfort. In addition, when computer systems are patched the organization that creates the patch/fix normally details everything that the update will address so that you are aware if something is fixed as well as if it introduces an issue that is NOT detailed as fixed. Without the information there is no way of knowing....I am hoping that Chrysler Cares will be able to get us that information.

I got to experience this last night myself.

I heard it blowing away in the garage while I was in the house watching TV. I took it in for the U73 fix the day before, but I don't think its related. We had triple digit temps yesterday and I'm sure the garage was at least 90. I plugged it in right away when we got home with 10% remaining. After about 20 min it was up to 30% when it got really loud. Since we didn't need to go anywhere right away, I just unplugged it and waiting for cooler temps in the morning.

But it is alarmingly loud. It is not a sound you feel good about coming from your $50k vehicle.
