Picked up a 2019 trail boss last Friday. Always had Tacomas in the past and this is my first Chevrolet. I had to hit the brakes hard for a light on icy roads and the truck stopped like a champ. But.... Then ECU error, ABS error, and Stabilitrak error. On Star emails and lit up dash.
The power brakes stopped working and had a top speed limit.
The dealership is replacing the brake Master cylinder. And says the active grill shudders have faults and GM had no solution yet. I see I'm not the only one. Hope they get this fixed soon.
