Great! Here we go again! It's not what you think it is.
So about 5 months ago my wife's Ioniq 6 popped the "Check electrical system warning" message. Turns out the HV pack failed and was replaced with a remanufactured pack.

My wife charged her car up to 100% last night in preparation for a trip to Spokane to see our daughter. We live about 60 miles north of Seattle. She has made this trip in her car at least 4 times so she knows what to expect, where she has to stop to maintain her personal comfort zone, etc.
Well guess what? It looks like this remanufactured pack has also failed. I can't check codes because the car left my wife stranded 160 miles away at the Tesla Supercharger in Cle Elum!!
The first clue something was wrong was the car was reporting 3.1mi/kW efficiency yet it took 80% of the battery to go only 162 miles so she wasn't going to make it to her normal EA stop. So she stopped at the Tesla SC in Cle Elum at 20% remaining. This is very typical behavior for a bad/weak cell and/or out of balance pack.
The next clue something was wrong was the atrociously poor charging speed. I realize the max speed on a TSC is 97kW but she got a peak of 20kW and settled at 13kW. This is barely faster than our L2 at home. Next clue something was very wrong was the car started reporting something impossible. The SOC was 50% yet the car was saying it would be done charging to 80% in 1 minute. At 13kW. Yeah right!
50%-80% in 1 min at 13kW? Yeah I don't think so.
Very soon after that the car quit charging completely and then popped another "Check electrical system warning." Unlike the last time, this time the car was really unhappy with something because it would not go into D or P. In addition it would not close the contactors to maintain the 12V. I bought my wife a power point volt meter and with the car ON (NOT accessory mode) it would only show 12.01 volts. This is definitely NOT ICCU.
To add insult to injury, there was no Lyft, Uber or even a taxi that could take my wife the 25 miles to Ellensburg to grab a rental car from Enterprise. She was forced to get a ride from the tow truck driver to the tune of $300!!
Thankfully the tow was covered by Hyundai roadside. They have to tow it to the closest EV certified dealer. Which is in Auburn! Bud Clary to be precise. I hope they treat us better than their Yelp reviews indicate.
It always sucks when a car breaks. Things happen. I get it. The thing that pisses me off is that I told my local dealer that I had serious misgivings about the reman pack since historically reman EV packs seem to have issues. The way I see it they had a chance to fix it the first time but they chose to go the cheap way and use a reman pack. Now we are both paying the price for that.
If Hyundai does not reimburse for out of pocket expenses on this I'm not sure what I can do about it other than spend the rest of my days bad mouthing Hyundai on every social possible. I mean can you sue a manufacturer in small claims court? Would a person prevail? No idea and I hope I don't have to find out because Hyundai did the right thing.
Edit: I looked into the Hyundai roadside trip interruption assistance. Turns out this event qualifies by the skin of our teeth. Trip Interruption kicks in at 150_ miles away from home. According to Google maps the distance between our address and the Cle Elum TSC is 155 miles. Talk about cutting it close!
