Had a warning on dash board about traction stabilization system. Couple days later the driver front window stopped working and now the door locks are acting up. Yesterday the hummer cranks but wont start

Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. Honestly, what I'm reading indicates multiple problems for the same vehicle in different areas. Because you're having problems at the same time doesn't mean it's the same concern causing everything. I would recommend performing diagnostic testing for each concern to determine what's going on. https://repairpal.com/auto-repair-near-me Click the link to find some shops near you who can help out!
