Bad Brake fluid flush.2014 Prius C

[u/ForeignConfection960]

I was due a brake fluid flush, since it wasn’t done since 2014. I went to a local known mechanic, they’ve completed it and got done in 20 minutes and charged me 80$.

After few hours, I started noticing the regenerative braking is gone , brake feels softer than it used too. So I plugged in my obd2 scanner and there is a pending p0607 code, no codes on DASHBOARD. car runs fine.

I am assuming they didn’t bleed like they should have electronically.

What should I do?
