Warming sound from dash on cold start

[Mrsparkle3000]

07 LX with 148k. This the third time this week that it happened, all on a cold start, after that it’ll start up with no sound or lights on the dash. The ABS, VSC TRAC, VSC OFF lights up for couple seconds and clears. I just had a refurbished brake booster replaced back in October. Also have transfer case, transmission flush, radiator flush don’t couple weeks ago. Am I counting my days on the brake booster crapping out on me again?!?

I think yes. Should have gone new.

Have you counted how long the booster runs at key on, per the procedure?

On a cold start the booster would run around 5 seconds but no noise on the ON position
