Denali2019junk

Glad I found this series of conversations. Own a 2019 Sierra Denali brought my truck in for a simple oil change they said hey have some recalls to preform we will do those at the same time. It has been a nightmare ever since. The truck has about 20,000 miles on it and owned for a year absolutely no issues with it until they performed the recalls. I picked it up after oil change and recalls completed drove about an hour. I was driving about 70 mph on a busy road and dashboard lit up like a Christmas tree - all the same indications that everyone else is noting, I had no brakes, completely press all the way down to the floor, no way of stopping: Brake System Failure 62 MPH top speed Service ESC Service Steering Assist Service Assist is Reduced Drive with Care Luckily I coasted onto an off ramp able to reduce speed without hitting anyone. Shut the truck off and restarted and it worked. Drove straight back to dealership left it there. They called the next day indicated something with the front camera was reading that I had been in a collision and it was malfunctioning. Waited three weeks for the “part” to replace the front camera, they tested and drove the vehicle, called us for pick up. Picked up the vehicle this week, dealership indicated all in working condition. Drove the truck again for approximately one hour and same thing happened, no brakes, flashing dash and also this time the truck shut off numerous times. Needless to say not happy called the dealership once again. Truck back to the dealership, they replaced the main wire harness, called said it was good to go, they drove it and tested it all ready! Picked up the truck yesterday drove for about another hour. On my way home with my children in the car the same error codes lit up the dash and I had no brakes once again, I am beyond appalled at this point. The dealership has no clue how to fix it, I am concerned for the safety of myself and my family when driving this overpriced vehicle and further more I never had one issue until they messed with it. The truck is sitting back at the dealership with no end in sight as I am reading all the threads available. My advice DO NOT perform the recall update if you want your truck in working condition unless you already have experienced issues.
