What 2016 GMC Sierra 3500 owners say
Brakes
Brake pedal has to be pushed almost all the way to the floor to stop, this recently changed from barely having to apply any pressure to the pedal. Took it to Quebadeaux gmc on 11-10-2021 and they inspected the brakes, said everything was good and that's normal for the brakes to be that soft. That's not normal or it would've always been like that.
When braking, the service trailer brake system message and service stabilitrac message appear on the dash and brake pedal gets soft to hard repeatedly and truck pulls from side to side violently as if one side of the trucks brakes are working and the other side is not.

Backed it out of the garage to go somewhere, got on the main road and it was wondering with a lot of play in the steering wheel, next hit a bump in the road and the front wheels started shaking uncontrollably until I slowed to under 40 MPH, hit another road seam and it did the same thing.took it to the mechanic, he diagnosed it as a failed steering box. Truck only has 27,500 miles on it. Never seen a dirt road, not driven in the winter.$1700.00 later its fixed. Many complaints about this on the internet and GMC has not recalled these trucks for this problem they know about. Has soured my trust in their brand.
