  1. Hyundai IONIQ Hybrid ('17-'21)
    Hi all. The title says it all really. I recently had RAC out to replace the 12v battery which went dead, and since that I've had a message on the dash saying "Check Smart Cruise Control System" and another icon indicating that it is disabled. Authorised Hyundai dealer wants £95 for the...
  2. Hyundai IONIQ Electric (EV) ('17-'21)
    Hi everyone. I am desperate with the Hyundai technical service and I am here to share with you the technical problem to see if it has happened to any of you. I have an IONIQ 38kWh Klass (lowest trim level in Spain) from October 2020. Since November 2021 I started to notice that the auxiliary...
  3. 2017+ Hyundai IONIQ Service And Maintenance
    Hi, My Ioniq has a dead 12 V battery. It's under warranty, and I've been chasing the dealer for over a month, but they're saying they can't get a replacement. I've been to the local auto electrician and had the roadside assistance people look at it, but they are both saying "it's not in our...
  4. Hyundai IONIQ 5
    I decided from reading other's experiences that it won't hurt to charge the 12v battery manually. Can anyone see a potential issue with doing this? The reason I ask is maybe that's why my climate system is only blowing outside air. Perhaps the IONIQ 5 finicky "automated" system doesn't like...

  8. Hyundai IONIQ Plug-In Hybrid (PHEV) ('17-'21)
    I’ve been having issues with my 12v battery draining. Since I bought the car, I often see the ‘aux battery saver has been used while parked’ message come up - maybe twice a week. That’s telling me that it gave the 12v battery a boost from the high voltage battery. Now that I’m driving less...
