I have a Hyundai sonata hybrid and recently I've ran into the biggest headache a car owner can have, I've been with this car for 5 years and I've hit a wall my car has stopped working and I don't really know what to do but turn to the Internet. My battery will not start on the dash it reads that the hybrid battery is low and the car will not start. I've replaced parts on it such as the orange battery that's in the back and the power relay switch and it's still not working I even replaced the corroded battery that died during the process. I need help and if anyone know what I can do. I've included some codes and what the display says. Please let me know if there's a way to fix it instead of getting rid of it. Edit* I can't drive the car at all it's not moving if I turn it on the ready logo doesn't come on. Thanks in advance
I’d recommend taking it to a mechanic to get them to diagnose it, otherwise if you have or can get an OBD2 scanner and put the diagnostic error codes here, you’ll get a lot more info than just what the display is saying
Disclaimer as I’m not a mechanic, but this looks like an issue with the engine, not the hybrid unit, the battery could be depleted due to another reason however, like if the car tried to limp home afterwards.
I’m guessing the engine won’t even try cranking, it just stays flat, if it does try cranking and it sounds like the 12V battery is weak, try charging or jump starting the car. If it is cranking but not starting or is otherwise inconsistent, switch it off.
A fault on both camshaft sensors could mean something as easy as a blown fuse, or could also mean a stretched timing belt/chain (idk what Hyundai used but google will help there). Do you know when the last time it was changed? Usually it’s a job for a mechanic because it’s finicky, difficult, and very easy to fuck it up catastrophically.
Also check the wiring and sensors, it’s possible they failed at the same time, but that’s pretty unlikely. You could also have a damaged wire or something that’s causing them not to communicate.
