Got these codes. They came up the other day. But went away. Fast beeping from car as well. Regen went away and then power brakes. Not sure how to proceed.
Brake booster fail, a very common failure on gen3. Usually about $2500 at a dealer, less than half if you can diy although it is an involved set of parts and requires a Techstream bleed after. Coverage by Toyota is 10 years or 150,000 miles from first use. Don't clear the codes if you try for a policy exception with Toyota.
Yeah, they gave me an exception on the Inverter extended warranty. 3700 dollar repair. I can only hope. Prob drop it off Monday and hope for the best. Worst case, I have to pay a diag fee.
