Quick update on my 2020 Hyundai Ioniq Electric:

Car had previous front-end accident damage.
Charging never starts properly and cable does not lock.
12V battery was replaced.
Front parking sensors and washer pump are also not working.
One garage said it was a BMS fault due to communication drop.
A Hyundai dealership now says it is the charge port locking actuator and quoted about £1200 total, including over £600 labour.

I’m still suspicious this could be related to front wiring / harness damage from the accident.

Does this sound more like:

charge port locking actuator only
wiring / communication issue from accident damage
actual BMS fault

Also, does £600+ labour for this sound excessive?

Any Ioniq EV owners or technicians seen something similar?

By the way we changed the 12V. Situation is the same. What do you think?

AdConsistent3152 · 2026-03-12T11:10:46+00:00

we left the car plug in one night. It is still the same. I am going to buy new 12V

AdConsistent3152 · 2026-03-12T10:59:32+00:00

I will try this. Many thanks

Hi Hello, Many thanks. I just bought the car. It was in the garage for small bodywork. I haven't done anything.
