Very interesting that this same issue is appearing in other, newer Hyundai hybrid modules. Mine is a 2022 Elantra hybrid Limited. Thanks so much for this video.

Hi, I really enjoyed the video! Thanks! I have P0A4C Error for almost two weeks just after HSG belt and brake fluid change. Do you have any idea? It gives an interminent error, not always on but if i drive in the city, it pops up. I checked the HSG cable but not the whole harness and Hyundai dealer could not find out the issue and thought everything was normal. Thanks!

[@barneykennett9282]

Nice...👍.

Thank you for this video, just what I was looking for! I liked and subscribed! My 2018 Hyundai Ioniq has been at the dealership where I bought it new from for over a year trying to determine why it keeps getting a POAA6 code and the Hybrid Warning light on the dash. This all began in 2021 when the car had 95000 miles on and it was missed diagnosed as a software issue. The latest information from the Master Tech at the dealer is "the Hybrid Powertrain Control Unit" has finally completely failed and that intermittent glitches with the HPCU has been causing the issue all along. At this time I am working with Hyundai in an attempt to get them to cover the failed control unit even though the car now has over 100000 miles on it, fingers crossed!! My question is, if they deny my request, can I purchase a used HPCU from a parts yard and replace it myself (I have worked on my own cars for years)? Will/can a used HPCU be reprogrammed to my 2018 Ioniq? Are the Ioniq HPCU's used in other Hyundai/KIA models? I asked about the cost to program a new one and was told $300, does this sound correct? Is there a chance that I could just replace my bad one with a used one and it would work without reprogramming? THANK YOU! Puc
