Friday night my wife was driving through some bad weather (hard rain) on the highway. Maintaining speed was okay, but trying to speed up or slow down gave a clunking and some hesitation. She mentioned feeling physical clunking like something banging underneath. Eventually came to an offramp where she needed to stop at the end and there were a few more clunks, then a whole bunch of lights on the dash. It wouldn't shift into Park right away, and eventually said "Hold brake to prevent vehicle rolling" (or something like that). The E-brake would hold the van still but without it it would just roll. I looked underneath from the side but it was dark, wet and in a pretty dangerous spot, so I couldn't see anything of value.
The dealer rolled it into their shop on Saturday and pulled codes but their hybrid mechanic won't be in until Monday to look at it officially. I looked at the list of codes the dealer had and they were errors about vehicle speed and traction control, but the list was long and I didn't have a chance to write them down. I'm hoping this is as 'easy' as a broken CV joint/CV shaft, hopefully not something internal, but I also hoped the basic tech who pulled codes might have been able to recognize a broken CV shaft (although maybe he wasn't allowed to do anything to it except reading codes). I did some searching for Pacifica Hybrid, differential and CV shaft and could only found one other poster here who mentioned a broken CV joint, https://www.pacificaforums.com/foru...im-dumping-my-pacifica-hybrid.html#post528633
On a slightly comical note, my Chevy Volt was also in the shop on Friday for a high voltage system error, so the I had to pull out our next newest vehicle, my '73 Buick to go rescue the passengers (see attached image). Not a good day for our high tech vehicles! A state trooper pulled up behind us to add some safety lights for a while and when he got out he said "what's wrong with the Buick?" He laughed when I told him that was my rescue car, it was the new van that was broken down...
