Air bags · crash · 2009-04-03 · NHTSA complaint #10264087
Now the ignition and ac will not work. Oil pressure sensor reading wrong. Took it to get code read and 35 codes came up. Had to put on a toggle switch just to start it. Cant see speed and that makes it very dangerous to drive at this point. Think all of this is due to water leak on drivers side.
Electrical system · 2018-11-30 · NHTSA complaint #11155129
The seat heater switch, located above the driver's door armrest, turns itself on when the car is operating. The heated seat becomes extraordinarily hot rapidly and it is difficult to turn off - every bump and jar in the road turns the light and the seat back on.
Seats · 2017-11-25 · NHTSA complaint #11048367
The brake fluid lines rusted at the area under the driver side wheel, causing the fluid to leak unexpectedly, thus rendering no brakes. The leak happened on my vehicle and another in this same area.
Service brakes · 2017-10-26 · NHTSA complaint #11040025
All four lines are extremely corroded at bracket and at least one of them failed completely and instantaneously. Unlike gm reports that it's a dual brake system and vehicle will retain braking capabilities in our case this is false . Word needs to go out about these vehicles but preferably a recall.
Service brakes · 2016-09-18 · NHTSA complaint #10907442
Tl* the contact owns a 2004 chevrolet suburban 1500. The contact stated that the rear hatch would not open. The dealer stated that the actuator needed to be replaced. The contact notified the manufacturer. The vehicle was not repaired. The approximate failure mileage was 200,000. Updated 04/20/16
Structure · 2016-01-05 · NHTSA complaint #10818148
Brakes failed under hard stop (highway, in motion). Intermediate steel brake line failed to rear brakes in a mode of rupture due to corrosion. All other steel lines were corroded and contacted gm. 2 other silverado line vehicles owned also failed this year due to corrosion. Gm response was that no recall existed.
