How long has your 2003 GMC Envoy had this problem?
RepairPal Certified shops can diagnose and repair your 2003 GMC Envoy. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Your 2003 GMC Envoy does not have a timing belt,it has a timing chain(either engine)and should last the life of the vehicle/engine.You possibly could have a bad,new/reman alternator right out of the box. Take it to Autozone,Advance,or O'Reilly's and get them to test your charging system,it's free.If you end up needing a battery,your Envoy takes a group 78 side post battery>1000 cranking amps>800 Cold cranking amps.takes 30-45 minutes to change the battery,if you've never done this one before.The battery is inside of a cooling box/case under the hood.
