For months now wire harness part number 842-909-97, rear driver side passenger door wire harness. Wire and connector damage from being poorly manufactured, wire cracking and breaking apart. Waiting for new item availability, can't operate door locks, window. Dashboards light stay on. No dealership or parts supplier in country has any availability or previous part number to replace. Waiting on general motors to bring new wire harness to market. No eta and item is listed as backorder .Been an issue for years now. I can't open My back door in fear of not being able to lock the door and have trouble light stay off. I have a three-door vehicle now instead of four.truck is barley 10 years old. Cost a lot of money for this vehicle.

Noticeable at night. Headlights on, turn signal on, foot on brake slowing down, making a turn, 1) headlights flicker, 2) headlights flicker and complete dash goes black, or 3) all of #2 and steering goes stiff. Has been happening more often. Last time, during the day, turning against oncoming traffic and engine shutdown, started again, shutdown and started, again with dash going black and steering went stiff. When the engine stops and restarts, it does it on its own. I don’t need to turn the ignition key. Very unnerving. My wife won’t drive the truck. Safety at risk is a “yes”. I have noticed when this all happens, the traction control wording comes on the dash and a bell rings. All this has been happening over the last six months. Vehicle only has 94K miles on it.

Rear window defroster overheated/caught on fire. It will be available for inspection unless GM rectifies the issue and removes the components in question. Cabin filled with smoke and a small fire broke out immediately behind the rear headrest/seatbelt location. Rear window section shattered, most of the glass is intact but some pieces were ejected. The problem has been reported to GM but is still in the investigation phase. The vehicle has not yet been inspected as I have just started the report filing with GM. No warnings, indicator lights, etc. were present before, during, or after the incident.

Chevy and GMC pick-ups are having engines blow up because of a problem with the system that makes the pickup go from 8 cylinder to 4 cylinder. This needs to be looked into immediately. Chevy has taken no action/responsibility to alert people that this is a problem with their vehicles. At the advice of our mechanic, we purchased something that completely turns off the active fuel management or multiple displacement system. This is an almost certain problem waiting to happen. Chevy should be notifying people of the problem and offering to pay for the fix. Or maybe a recall should be issued. Please look into this.

I have experienced engine failure in my 2014 Silverado 6.2L on 3 separate occasions. All caused by the AFM system. Rockers lock into the wrong position while transforming from 4 cylinder to 8 cylinder operation. The first two occurrences bent lifters and caused a failure to the catalytic converter. A certified GM service department at a local dealership replaced parts covered by warranty. On the third occasion the rockers locked into the wrong position, bent push rods, damaged the cam shaft and caused a failure in the catalytic converter. It was taken to the same GM service department at Lou Fusz Chevrolet. My 5 year warranty had expired and GM refused to cover the parts they had previously replaced a year prior. I was quoted approximately $10k for repairs and $16k for full engine replacement. After some back and forth with the service department manager I requested to speak with the lead mechanic. He informed me that it was an AFM system problem he was very familiar with. He stated to me that I would be better off taking it to a private shop and bypassing the AFM system as he was “working on” 10-15 vehicles a month with the same issue. At the time I had reached out to GM corporate about the issue and I did not receive a correspondence. I have all of the paperwork and receipts and all other service records dating back to my purchase of the vehicle in 2018.

I called GM and the Lady told me that there 5 recalls on this truck of which 4 were taken care of. there still remains one left undone. I purchased this truck from a private owner. the one remaining is the seat belt wire issue. A new warning has appeared on the dash, saying service trailer brake system. This a non stop warning while driving the truck. Very distracting and dangerous. I looked on you tube to see if anyone has this problem. yes there are some. One incident stated that to resolve this issue, someone needed to check the trailer receptacle plugin for corrosion, or broken wires. IF all is good there check the other four connectors under the truck on the frame. Finally if these are all good, then check the fuse box under the hood for the fuse for this braking system. The representative that I talked to from GM said to take the vehicle to a local Dealer for analysis to see where the problem is in the trailer braking system. Dealer labor rates are high. The representative stated that there is a payment assistance program available through GM if a Dealer takes care of the situation. Is this true? I need this truck every day for work. Please address this issue . Thank You, [XXX] My email [XXX] . ph# [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The truck has been having the inactive airbag sign on for about the two years that we have had it.
