“At 45,000 mi, had to replace ABS hub sensor assy due to false activation. I have since replace 3 more assys costing over $400 each occurance. At 100,000 mi, had to replace a leaking brake line which had rusted through and at 120,000 mi lost all hyd pressure while braking to avoid several deer entering the roadway. Replaced all brake lines at a cost of $1200. There have been many consumer complaints on both issues, but gm will not assume responsibility for either.this is the 9th silverado I have owned over the past 40 years. Next one will be a ford.”Owner report · Service Brakes · Jan 2020

“I parked my truck the blower worked fine got in it 2 hours latter and it did not work.the wires to my blower melted and hot almost started a fire in my truck. No smell no sign of the wires getting hot. The only thing I noticed was the control panel got hot when it was on so I kept it off. If I had not taken it to the shop 2 days after my blower stoped working I might not have my truck. It might have caught fire with my kids and I in it or with my 17 year old driveing. A recall on this part would be nice or find out why it is doing this.”Owner report · Electrical System · Jun 2019
