    So this happened this morning, all these dash lights. Used my Autel and got a P0A80 code, replace hybrid battery. No other codes. Have not been having issues with the hybrid battery at all! It’s even been fully green at times on the hybrid infotainment screen. Should I get a new hybrid battery from Toyota, or independent specialist? It’s going to Toyota on Saturday for some suspension issues anyway. There is a local independent specialist near me. I’m in the UK.

    idk the options you have there. new oem is best, but expensive. if you intend to eep the car, it is worth it.
    here, there are myriad rebuilders, some better than others but all a crapshoot for longevity.
    salvage is another option, but can you trust age and miles, and how long it's been sitting?

    Update: Spoke to my local Toyota. They asked re the 12V battery, and if it has been replaced recently, which it has, by them. They said this can cause the error code to be thrown up. I’ve cleared the code, no symptoms or limp mode etc. Can the 12V being changed cause a replace-hybrid-battery-code?

    No, only a weak 12v can cause unintended error codes sometimes.
    It should be load tested, even though new.
    If it is good, you should have the codes checked with tech stream, that will give you more detailed information on the hybrid battery cells

    expect that red triangle to go back anytime soon, when that happened to me it took several days to show up and then it becomes frequent. 12v issues can cause a lot of codes other than p0a80 (like codes for car modules "under voltage")
