How about starting say a mile further down the hill and see where the noise happens on this occasion? Theoretically it should happen somewhere close to a mile lower, give or take a little ... or more accurately after a similar amount of elevation drop....
2. Since the bang occurred at the same location as before, this makes me think that it is purely an elevation caused issue that happens once I descend a certain amount of elevation down the mtn.
I'm going to add a +1 to this theory.So my conclusion is that the bang has nothing to do with regen, it only has to do with changes in pressure. It's still undesirable of course.
Hi AndreHello guys. I'm sad that all of us are having same problem. I also hear this bangs every day... becouse my daily route is where i go uphill to 700m altitude and then down to 200m and this banging is happening every day, so it starts to make me nervous and i drive it to Hyundai dealer and leave it on servis. They find NOTHING is wrong, and then i get technical answer that is normal, and it's happening due to temperature difference in battery housing and external temperature and also becouse of the different pressure due to altitude difference.
But that i don't find satisfying answer, i didn't buy a car worth 42000€ and then they say that something like that is normal...then it should be told while buying, and buyer make decision if he will deal with that or not.
Just curios if someone of you just get this solved, so hyundai repair it somehow?
It's not my fault if they make battery housing flat and so thin that it pops out due to temperature or pressure. If housing would be made with some reinforcement or stepped sheet metal i think that would not be happening.
I think this problem concerns the 38kWh version.Hi Andrej, I've done lots of fast charges and never heard a bang, even with 67 kW going in and the battery heating quite quickly. I don't think I've ever heard of anyone else having heard it then either.
I've also done several large elevation gain/drop trips (the BC Coquihalla - +/- 1,100 m over 40 km) and never heard it either. But perhaps my rate of elevation change is slower than yours. However, as others have said, it isn't something to worry about. Though I'm sure it's rather annoying.
Hi, If you live in Tenerife I think you will hear this noise many timesHi,
I experienced the bang a month ago, going down from 2000 metres to sea level. It happend at around 1400m and then again at 700m. This thread has been very helpfull, and the car seems to be perfect. But my concern is about possible damage in the sealing of the battery pack in the long term. In my daily commute I never go above 600 metres, so not a big problem, probably.
Could it be an especific issue of the 38.8Kwh pack, or is it happenig also to the 28Kwh cars?
I am from Slovenia, and now it is winter... This bang on DC charger happens when battery is cold, and outside temperature about 0-3°C, before when it was warmer, i never heard it while fast charging. These days when it is cold bang happen every commute drive every day, also every fast charge.. It is really disturbing to me.No!!! I have never heard a bang while it is charging. I live in Australia where it doesn't often go below 0*c I have had it cut out while DC charging when it was in the sun and the temperature was over 30*c but that's it. Sorry I can't make out your flag so not sure where you are from. Do you hear the battery cooling pump come in when it is charging at over 38 kW/h ?
