This started back in October when the cold weather rolled in. It was throwing two codes which I talked about here: pacificaforums.com/forum/193-2017-chrysler-pacifica-minivan-general-discussion/40969-error-codes-p0128-u1124-2018-pachy.html

Now the van is throwing more codes. They replaced the thermostat, cleared the codes, and a few days later the light was back on (big surprise). My wife brought it back, they took several hours to look at it, and then told my wife that Chrysler knows about the problem (they couldn't say what the problem was) but that they don't have a fix for it. They sent her home with the van and then said that they would call us back with a fix. That was back in January. Fast forward to now, April 17th, and no call. I called Chrysler Cares and they told me to try a different dealership and that they shouldn't send us home with the check engine light still on. So, now I'm at a different dealer hoping that they'll actually take care of it. Hopefully Chrysler actually does care, because so far my experience has been the opposite. When I brought it to Autozone before I scheduled the appointment it was throwing 5 codes instead of just two:

P0128
U1124
P2183
P01E4
P0128 (Yes this appeared twice)

As I sit in the waiting room I overheard the service guy that it's apparently throwing 6 codes now.

From my research so far it would appear that the battery heater pack is malfunctioning but I'm not entirely sure.

Any advice or service bulletins about these would be great so that I can be informed when they tell me what they need to do. It's still under warranty but I'm getting close now (28,000). Thanks!


EDIT: Apparently the other dealership put the wrong thermostat in, the part is supposed to end in AE but ended in AD. They aren't able to work on it, because mistakes by other dealers aren't covered under warranty. They're talking to a rep to find out what they can do since I don't want to go back to the other dealer. They are convinced that this is why the CEL is on, but I'm not convinced. They told me the other codes wouldn't trigger the CEL... which I'm really dubious of.

Sounds like BS to me. call Chrysler cares and let them know what is going on. Warranty work done at a dealer under warranty should be covered at any dealer under warranty. Sounds to me like they probably won't be able to bill for their time since it was another dealers fault. Not your problem. Whenever they move up a part numbers letter designation it is usually because something has been modified. Maybe there was an issue with the Hybrid that initiated the Themostat needing to be revised??

I am still focusing on that U1124 code for which I posted a bulletin in your older thread. Show them that bulletin and ask them to replace the battery coolant heater connector. It sounds to me like both of these dealers have service technicians who aren't properly trained or don't have much experience with the hybrids. They know how to replace a thermostat because all cars have one of those so they did that because it was the easy thing to do. But when it comes to a battery coolant heater connector replacement that requires them to partially drop down the hybrid battery pack, which in turn requires precautions against electrocution then they are reluctant to take action. In another thread there was a guy whose PacHy has been in the shop for 7 weeks because they didn't have the special gloves required for high voltage work.

Yea I feel like I’m getting jerked around. They looked at the bulletin (I brought it with me) and said they inspected the connection and it was fine. I started a case with Chrysler cares but I’m really getting fed up. Spending this much on a car should get you better service than this.

Hello Masterfoo,

We're sorry to hear you're having such a tough time. Is there a case created on the customer care side so that you have an additional layer of assistance while working with the dealer? Send me a direct message as I'd be glad to help and escalate it.

Hi Jasmine,

I sent you a PM. I do have a case number but no one has called me back in the promised timeframe from Chrysler Cares...
