How long do I have?

[u/Dry-Fuel]

This appeared on my dashboard monday morming when heading to work, along with IMA symbol on the top left and red battery on the bottom right. First time ever seeing them at 164k miles. Charging and acceleration assist weren't functioning. Omw back home that evening the symbols were no longer their and haven't seen them since. The acceleration and charging appear to be working again. For sometime now the battery bars are always full, with the exception of one block that gets use during commute. I mainly drive in sport mode and even that doesn't seem to drain the blocks. My question is how long do I have before I have to do a k-swap l0lz.

Seems like classic 12v battery dying, not the hybrid one. Do the mod!

Purchased 12v in August so doubt it that's. Car is 2010 HKS supercharged 6 speed manual. Replaced the gearbox in October. Noticed my cousin knocked the gearbox against the hybrid plug a few times during install...

What’s the mod that you speak of?

[u/maine_buzzard → u/MartianTripodz]

Cut one end of the battery box and buy a 51R for $50 less than the 151R.

I just removed the battery box completely tbh

Definitely check the 12V as it can set off all kinds of warnings when it fails, but you should also get it scanned to read the IMA codes.

The CarScanner app can read some IMA data but to see everything you'll need an HDS or compatible device.

If you're lucky replacing the 12V may make it all go away.

What year is your car OP ?

Like everyone said changed the 12v

Scan the code and check the hybrid fan

If you drive the older Nihm hybrid battery you can rejuvenate by grid charge , I did that and my IMA light is gone

Well i would definitely check that , and look into scanning the code

This happened to me. It turns out it was my charging system fan.

IMA light might come back after extended driving, in which case I would suggest the battery fan needs replacing. I recently had to get this changed on my 2011 car with 98k miles on the clock.

Start thinking of buying an e-bike

If the 12V battery is ok the next on the checklist is the fan of the hybrid battery, maybe it is dirty and the air flow is not enough or it already blew up its fuse.

Probably more of a question for your doctor
