2016 Chevrolet Silverado Electrical System Problems

On January 6, 2026., I was backing out of my son's driveway when I heard a loud pop, it sounded like a rock hitting the back window of my Silverado. I then discovered the driver's side of the back window shattered. Prior to backing out, I used the auto start to warm up my vehicle. I did some research and found there was a recall for this issue that was supposedly completed by Lithia Chevy of Helena on 6/29/2020. GM is refusing to replace the rear slider window stating there's no recall. I then reported the issue to GM Product Assistance claims it's do to wear/elements. See recall below. GM Program #N192265660 Status: Complete Description: Certain 2014-2019 model year Chevrolet Silverado and GMC Sierra vehicles equipped with a power sliding rear window (RPO A48) may have areas of high electrical resistance on the rear defroster circuit. This could be caused, in part, by mechanical stress from opening and closing the rear power window, intrusion of debris, and use of the rear defroster. Over time, this condition could generate heat that could melt the areas surrounding the circuit. In rare instances, this heat could cause a non-propagating fire, increasing the risk of property damage or injury. This is the second time Lithia Chevy has claimed they completed a recall. On July 28, 2023, my brakes failed during a 200-mile trip to my hometown. After several days of battling with Chevy and General Motors I paid a private mechanic 100 to verify the vacuum pump had failed on my Silverado, Chevy finally fixed the issue on August 8, 2023. There was 47,781 miles on it at the time. See Repair Description below showing they supposedly completed the recall, the same day as the back window recall (6/29/2020). Repair Description Dealers will reprogram the electronic brake control module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. Recall Completed: 2020-06-29

Was a light frost on mirror and back glass. Turned on rear defroster then all of a sudden back passengers side glass shattered.

Vehicle will cut off as if an electrical short and the Service Stabilitrak indicator will flash on the dashboard along with warning chimes. This has happened twice at highway speed (65mph) and several times at low speed (1st gear) especially while turning. The steering wheel locks and can not be turned. I've almost been involved in 2 accidents this week because the truck turns off while making a turn. Also the MyLink infotainment system screen has gone completely blank while driving. Although functioning, the displays comes on and off. This has happened off and on for 3 months.

Transmission issues already had one replaced 5/9/24 having issues again going to be 3rd transmission also having issues now with electrical system going out while driving and dinging noise,when entering or exiting vehicle here rebooting system whining. Going to contact car coverage to have vehicle inspected again for the problems.

I was driving my 2016 silverado high country 1500 with my travel trailer when the brakes stopped working making it extremely difficult to stop at a traffic light. Dashboard says service trailer brake system. I checked fuses and connections and turn truck on and off and issue is unresolved.

The contact owns a 2016 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The check engine warning light illuminated, and the vehicle failed to exceed 20 MPH. The vehicle was taken to the dealer; however, the vehicle was not diagnosed or repaired. The contact purchased a portable diagnostic machine and retrieved DTC Codes: C279A and U0422-71 indicating an electrical failure. The contact stated that the vehicle was purchased 30 days prior to the failure and the vehicle had been serviced by the dealer four times due to the persistent failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 77,000.

My local Chevy dealer has confirmed that the human machine interface (HMI) module has failed on my 2016 Chevy Silverado, causing the back-up camera to be inoperable. The camera is absolutely necessary at night when backing up due to window tinting and I believe this to be a safety-related issue. There currently is a nationwide back order on a replacement HMI module.

After air conditioning stopped working today on my 2016 Chevrolet Silverado 1500 Crew High Country, conducted research to find out if others experiencing the same issue. Discovered thousands of pages of complaints and class action suits. Vehicle is 7 years old and just went over 79K. Following several troubleshooting videos and write-ups by technicians, discovered the top weld on the driver's side of the condenser has leaked the refrigerant and made the system inoperable. Since the defective condenser (AC Delco) is no longer being used and a clamp replacement to support the weld was never installed, expect that GM or Chevrolet to replace the defective part.

The ignition switch is defective the truck will not turn on all the time I have to play with the shift lever and key to get it started

My vehicle just randomly shuts off, mainly when making a turn. I took it in to the dealership and had several repairs made but none of them fixed the problem. It’s definitely dangerous I almost had a accident at least 3 times. I feel it’s electrical due to the fact everything shuts off, the dash usually flashes before it shuts off. All electronics shut down and the vehicle turns completely off with no control of steering. I’ve come to the conclusion it’s electrical so I’m searching for a solution.

I was driving the other day and slowed to an upcoming vehicle, when I tapped the brakes the stabilitrak light flashed and all my dash lights and radio flickered, then when I used my turn signal the same things happened plus the windshield wipers came on, then when I went to merge back into my lane the pickup completely stalled out jerking us forward into our seat belts and then kept going. Later that day I went thru a drive thru and when I was turning the steering wheel jerked and wasn't able to continue turning and the pickup died. I had to lock the steering wheel in order to get it started again. This isn't the only time the first issues have happened or the steering wheel being jerked and stalling out, but this is the first time it completely stalled out in the highway and that is not okay. That is a complete safety issue and I'm not the only one who has had this issue, however when I have talked to a mechanic about it they couldn't find anything wrong and had no answer for me. There are several recalls on the years before the 2016 chevy silverado but nothing for them, and this is a big safety concern.

Grounding issue when turning causing the steering wheel to yank the to a random direction and lock up. Multiple Silverado owners have experienced the same issue and I nearly died. Chevy dealer did not identify the issue/ Cannot figure it out.

Trailer brake system warning has been flashing non stop for 2 weeks. I do not use or tow anything with this vehicle. Usually it locks up the steering wheel while parking my truck and shuts down the engine. Yesterday I was going 55 on the highway and the warning came on and it shut down the truck tried to put the vehicle in park and rapidly applied the breaks then the truck electrical system came back too and the truck was rolling I pull off to the shoulder to shut the truck off and turn it back on. At the time I had both my sons in the vehicle 4 years old and 9 months. Again usually it always happens when parking my truck (under 5mph) it will lock the steering wheel and totally shut down the trucks engine. Huge safety concern.

Myself, My wife, and my oldest son have all three experienced a loss of complete power in the truck during turns. All power on the dash, steering, and stereo goes out. The last incident required my wife to put the vehicle in park and turn the truck off and back on to get it to start.

While in reverse and turning stabilitrack light appears and jerks steering wheel from hand. Then a total loss of power and gait to start. No dash panel or power to vehicle.

3mos ago i had a fender bender in Mesa,AZ(my front end to pasenger side)her car was towed my wasn't for the next 28 days my truck was still driving just fine like nothing ever happened to it,at the end of the month my work was done so i drove bk to Cali and it was till the middle of April when this all started 2 months ago like normal I was getting an oil change from there I went home it was 5:30pm didn't go anywhere else that night ,the next morning I put my key into the ignition and it was completely dead, at first I thought it was the battery so I bought a new one, installed the new battery went on my way to run my errands 3hrs pass came home it was around 12:40pm,around 5:30pm I was planning on going to the grocery store went to start my truck wouldn't start truck battery was dead, nothing was left on no door was open no lights were on, so I towed it to my mechanic so he could put it on the scope to find out the general problem,called and told me that it was an electrical problem and my truck would have to be reprogram starting from the main chip in my transmission, going back in forth from my mechanic to the Chevrolet dealer in Victorville ca, it's still not in working condition yet and still trying to reprogram the last of these codes that keep appearing on the dash(2016 Chevy Silverado 6cyl 4door LT, never had any problems at all from the day I got it from the dealer back in 2019 of Mar, with reg oil changes, tune ups, ran like a brand new truck, very confused, upset, concerned about this matter, not to mention the cost for this, Sincerely [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Truck turns off when going in reverse, sometimes when brake is applied, sometimes when turning left and when left turn signal is on. It usually happened when stopping at a traffic stop or light or when turning left. This time it turned off when changing lanes on the freeway and almost caused a pile up. It was scary and it could have caused a lot of unnecessary mishaps. What happens is the engine turns off completely for a couple of seconds and turns back on. It feels like its a battery cable issue or some bad connection. The problem is the dealer cannot replicate the problem. Sometimes it happens often sometimes it happens every other day. So far I know a couple of other Chevy Silverado owners who have the same problem. I have a video of this problem if you need to see. My name is [XXX]. Email is [XXX].

I was door dashing then a service alert came on the dash… I had pulled over to check what it meant about the trailer brake system. I have never towed or have a trailer to tow around! So continued to drive then my truck cut off then cut on while I was trying to make a turn. Then I pulled over again and luckily a mechanic said it’s wiring that’s defected in my truck and I need to get fix! I don’t have no money to get this fix , is there a way I can get some assistance with this?

Rear Defroster malfunction. After starting the vehicle smoke was coming from the rear cab of my truck in the area that the power sliding window meets the rest of the rear window. In the same area, one of the metal strips for the defroster was glowing red hot. Seconds later the rear window shattered within inches of my face. There were no warning lights or messages prior to the defroster malfunctioning. The vehicle is yet to be disabled and the dealer refuses to look at the vehicle until the rear window is fixed. There are messages and recalls from the manufacturer for this issue on the same year make and model as my vehicle but for some reason my trucks vin number is not associated with that recall.

I parked my truck in the garage and shut it off, after a minute or two the starter engaged by itself, cranking the engine over, luckily I wasn't to far from and heard it. I tried by putting the key in the ignition, nothing, pulled the starter relay, still kept cranking, by the time I got some tools to disconnect the battery smoke was rolling out by the starter, disconnecting the battery did stop the starter. Had it hauled to my nearest chevy dealer. Had to have the starter, engine wiring harness and engine fuse block replaced. It fine now, but why? What would have happened if this happened in the middle of the night? This is an attached to house garage, there could have been a fire with who knows what consequences or outcome!
