Since it happens with ac and dc charging, it sounds like it is a fault in the OBC or the BMS. The OBC is supposedly only concerned with ac charging, so the BMS may be the one. I fear a costly replacement. May be better to trade it in.

I agree. Unless the price is really so low that it's worth taking a chance that you can get a replacement battery under warranty, walk away. You have to ask why the owner hasn't already done that. Perhaps KIA has refused because the periodic maintenance has not been done?

Ah, sorry I meant a trailer hitch-mounted cargo box that sits behind the rear bumper, not a trailer. That way the frontal area of the car isn't changed. Its not just an issue of the frontal area. A protrusion at the rear may create a fair amount of turbulence in the airflow, which causes drag. Ask ...

I think that a trailer (unless it was very streamlined) would create more wind resistance than a nicely faired roof box.

I have a 30 kWh model with 102% SOH. The GOM shows 150 miles in Summer (average say 25degC) and 120 in Winter (say 5degC), without heating and aircon (the GOM typically shows 8 or 10 miles more in that case). So, for your car, those values would be multiplied by 93/102*27/30, i.e. 197 and 157km with...

My understanding is that the 30kWh capacity is the usable capacity, and so excludes the buffer. Therefore the 28.8 also excludes the buffer.

It could be something like a correction to the diagnostic software to address false alarms.

I expect you will still get a 96 cell-pairs battery. The 30kWh battery has 100 cell-pairs, so you should have 96/100x30 = 28.8 kWh . Not bad!

...... Besides, it wouldn't make sense for them to give me one that is close to the "replace" threshold since I have more than 4 years left on the vehicle warranty and they'd probably be replacing it again. So, again, fingers crossed! Your car is a 2016, with the old technology cells. You...

Here, its only seven years. If you're sure its ten years for you, you could go direct to KIA USA and challenge that decision.
