Hi Gary_LaF,It’s sad to see how far back this thread goes.
I have a 2017 Pacifica and it has around 15k (got it in May 2018). We use the car for road trips mostly and just general around the town activities.
About a week ago I noticed the same behavior. The way I described it was rough sound and feel when accelerating, mainly under stress like up a small hill and in lower gears. It sounds like my old F150 w a v8.
I also can feel it in the gas pedal. I would say an almost grinding feel.
I have had prior minivans go through a few transmissions and we took a break and went to small SUVs...but after some great reviews we decided on this van. I really hope we don’t have another lemon.
I did look under the hood and don’t see any obvious parts disconnected but I’m no expert for sure.
The tech doesn’t have an apt for a little over two weeks and I didn’t want to drive and make matters worse. There is no engine or warning light at this time...
If anyone ever figured out what this was/could be then I’d love to know.
