Some Hyundai Ioniq 5 house owners are complaining that the 12-volt batteries on their automobiles are draining for no obvious motive.
When you verify the InsideEVs Discussion board, there are a number of submissions from Ioniq 5 house owners who skilled this downside, the earliest one from July 2022.
Mainly, these house owners state that their 12-volt battery – the one beneath the hood that powers all of the electronics, screens, home windows, door locks and so forth – will drain to some extent that the automobile will now not function.
Clearly, that is not nice and may go away house owners stranded as a result of they cannot even get entry contained in the automobile – or if they’ll, the automobile will not activate.
Luckily, Hyundai appears to have discovered the causes for this downside and a few options. The information was damaged by one Ioniq 5 proprietor on his YouTube channel, The Ioniq Man, who stated in a current video (embedded above) he was contacted by a Hyundai PR consultant with an replace from the engineering division.
We had been capable of confirm the PR assertion from his video with Hyundai for accuracy and be taught some extra, so listed below are the primary takeaways. The automaker says the 12-volt battery drain has been brought on by two totally different unrelated points.

The primary one is “overactive unauthorized Bluelink use by 3rd party apps that is waking up the car too often.” Mainly, unauthorized third-party Bluelink apps are requesting data too continuously from the Ioniq 5. Every time that occurs it wakes up the car, inflicting important draw till it goes to sleep.
Whereas the drive battery has sufficient power to recharge the 12-volt battery a number of instances, the battery saving mode can not sustain with tons of of even 1000’s requests per day – The Ioniq Man says the PR rep instructed him among the autos had been seeing as many as 5,000 Bluelink requests per day.
In response to Hyundai, the 12-volt battery drain subject has been resolved since January 31 by limiting Bluelink server site visitors to twenty transactions per day. As well as, sure problematic unauthorized apps had been blocked by the server, though their identify was not disclosed. Clients had been additionally knowledgeable to alter their Bluelink password.
Now, whereas most autos are solved since January 31, Hyundai says some got here again and required 12V battery alternative for failing to take cost after the battery was useless too many instances or for too lengthy earlier than January 31.

The second trigger that is not coated within the video however was communicated to InsideEVs is one thing Hyundai calls “EV Light On with DTC P1A9096 ICCU related.” To unravel this subject, the Built-in Charging Management Unit (ICCU) and ICCU fuse have to get replaced.
Now, some autos that solely had the ICCU fuse changed additionally incurred Diagnostic Hassle Code P1B77 (excessive voltage error within the battery pack) on account of ICCU failure. DTC P1B77 circumstances required the Energy Relay Meeting (PRA) within the EV battery to get replaced as effectively.
Hyundai additionally instructed InsideEVs {that a} rumor going round on boards these days in regards to the ICCU marketing campaign in Korea for coolant leak being probably associated and inflicting the above subject is fake.
“Fact: Not related. The Korea issue pertained to an Inverter Coolant Low Warning light on, not an EV Light On issue. It only applied to vehicles before 4/23/21 Production. Above issues have not been specific to such mfg period.”
When you personal a Hyundai Ioniq 5 – or a Kia EV6 or Genesis GV60 that are based mostly on the identical E-GMP structure – and encountered 12V battery drain points please share your expertise within the feedback part.
