My wife’* 09 Acadia recently gave the “service brake system” message. The brake light came on and the stabilitrak light came on. Some things I’ve read say it’* the brake master cylinder and the booster? Does anyone know if this is an ongoing issue, and if gmc will fix? I assume it’ll cost me but I’m trying to decide if this is something I have to try and tackle myself for much cheaper. Or should I just sell this POS. I already had the cracked wave plate issue, and the ongoing mold smell from the water that leaks under the floor!

There'* aren't too many ppl who want to pay much for broken vehicle https://www.carcomplaints.com/GMC/Acadia/2009/brakes/
