What owners report

Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.

I had a rusted brake line (driver side front) fail june 25th, 2017. This truck is 12 years old and has less than 90,000 miles. Immediately all braking was lost and the pedal pushed to the floor. Repeated pressing the brake only pumped out all the brake fluid. This was a sudden and catastrophic loss of braking.

Vehicle was in shop one time all ready because air bag light came on. Took in for service they said loose ground all fixed. Then on 9/11/2006 I was involved in an accident. A driver failed to yield while making a left turn. I hit him broad side at 45 miles per hour.
Air bags · crash · 2006-09-21 · NHTSA complaint #10168904
I noticed corroded and what I would call charred or burnt wiring on the wiring harness for the rear lift gate of my suburban. I noticed it when I opened the lift gate to gain access to the rear of the suburban. It appears that the rubber grommet material protecting the wiring harness, was burnt or melted away.

For approximately the last 4 years the airbag light has been on indicating an issue with the airbag system.

Air bags · 2017-02-09 · NHTSA complaint #10953672
My abs sensor light comes on and off numerous times a day, and cluster states service air bag. General motors should also fix this for free under a recall as others have the same issue with this vehicle. My third major complaint, is the vehicle starting problem/hard start.
Electrical system · 2016-08-08 · NHTSA complaint #10893888
I turned my 2005 suburban on and the air bag light came on. I took it in to the chevy/gm dealer who said, "the right, front, air bag sensor was the cause." it would cost $375 to fix it. I did not get it fixed at that time. It is dangerous because the air bags are inoperable.
Air bags · 2016-05-05 · NHTSA complaint #10863519
First incident eastern pa: 05/19/2014 aprox 119000 miles: after hitting the brakes hard to avoid a vehicle that pulled in front of me, the brakes failed (brake pedal would go to the floor with little braking action). Managed to safely stop. Found burst brake line in the rear end of vehicle.
Service brakes · 2015-09-21 · NHTSA complaint #10766829
The speedometer needle began "catching," not moving smoothly. After about 2 weeks it would not reset to 0 when stopped then after 1 more day it quit registering completely.
