BMS update fail...

Update here..or rather no update. Its the 3rd week now my car is waiting at the dealership for the new traction battery to arrive. Last week I got a coutesy call from hyundai corporate asking if the dealership was keeping me up-to-date on what was going on. I gave them a piece of my mind on that. They then told me they are coordinating with the dealership and the tech team and the battery was on back order and there is no eta. Basically it could take weeks . I asked them to give me another ev as a loaner or at least reimburse me for the gas in the loaner car. But they said it was up to the dealership to provide a loaner and they have no policy to reimburse. Oh well oh well...

 

Don't get me wrong I have had my moments of being livid, but I generally find there is no profit in sharing those emotions. I believe there are only 2 other EV approved dealers in the area. Problem is I don't really suspect they have that much experience either based on how few EVs are sold on the prairies. For the moment its one of those "the devil that you know" situations and I want them to to succeed, but if it suites me I will try another. I still really like my Kona EV and remain hopeful that it will be fine at some point. I am also grateful for being able to vent on this forum and kind words of encouragement.

 

I know a little about how you feel, when I had to go in multiple times with my clicking, getting the reduction drive replaced and then finally the motor. They were a little rude with me at first (when I referenced this forum), but changed their attitude when the reduction drive replacement didn't work and had to replace the motor, like I told them initially. And the recalls with the coolant leak and BMS. They always gave me a loaner, though, but a gasser, yes. I just didn't fill it with gas when I brought it back, and they never complained.

Things are better now, though, and no issues for the last several thousand kms. I do appreciate the many fine features, comfort, and nimbleness around town. I have even adapted to the premature FCA (hasn't done it to me for a long time now). So I do feel much better about my Kona now. Hopefully, you will eventually get yours all fixed up, too. It really is a pretty good car.

 

"Hyun. ... Campaign 960" is to update BMS to "include additional monitoring when parked".
Maybe I don't get it, but seems that the BMS-update (960) is the biggest current problem for existing Kona EV owners. I don't want to let my local Hyun. Dealer Service touch my '20 (mfd. 10/19) until they find out how to do it right.
Am I right ?
Would appreciate feedback about "BMS 960 Updates" done , especially by dealers in L.A. area.

 

That is a tough one as it seems at least some of the "updates" are safety related in regards to the main traction battery monitoring. It would be nice if Hyundai actually told us what the changes are so you could make a informed decision vs the typical "you better get this done or else" communication.

 

The basis for the update has been discussed in this article.

I am now a month without the car. The dealership is still waiting on the battery and the tools to remove the existing battery. So much for the two week estimate they gave me. I called hyundai corporate and they basically said that only the dealership can provide updates. I then asked them to either give me a new car or buy it back. They opened a case on that. Will see how that goes. I also need to see if this will qualify under the California lemon law as it has a clause for repairs not completed within 30 days.

 

In addition to the battery issue I had them add to the ticket notes the clicking sound issue I have been having since 4k miles which two dealerships were not able to diagnose. So hope that gets attention as well.

 

You might need to given them written notice asking for buyback, that usually gets you more attention from them. You definitely should invoke any privileges you have under the Song-Beverly Consumer Warranty act.

 

That sounds encouraging, hopefully the battery will arrive soon.
I'm into my 2nd week awaiting for a new wiring harness, with no further ETA updates. Dealer had a buyer for my loaner Accent, so I got "upgraded" to a Venue loaner yesterday. Its OK but I miss my Kona.

 

Wouldn't the two OBD2-readable PIDs for highest-voltage and lowest-voltage cells that
the BMS can report be the easiest immediate diagnosis of this, especially when watched
under various loading conditions?

You can read the Cell Volt difference and Isolation resistance PID's in Torque Pro, which is basically what Hyundai read off with their GDS.

They kept giving me a Sante Fe loaner, didn't have anything smaller. Didn't need two larger SUVs in my garage. It was a lower trim model, too, and I missed all the features and comfort of my Kona Ulitmate.
