2016 Chevrolet Silverado 1500 electrical problems

Filed Jul 25, 2026 · Electrical, Steering · GA

Approximately one week ago I was driving at a safe speed on a two-lane highway. Suddenly, my steering wheel and truck jerked to the right. For 8-10 seconds a warning message was displayed "Power Steering ... Drive Carefully." I took the truck to my local dealership. They scanned for trouble codes. The technician said something about an interruption communicating with the electrical system. My service advisor took the truck on a 15-mile drive and had no problem. They scanned again and there were no trouble codes. The service advisor said they could not fix the problem if they did not know the cause of the problem. I left the dealership. Since then, I have had 4 more incidents. Once the warning message appeared again, but no jerk of the steering wheel or truck; once there was the same warning message and a jerk of the steering wheel and truck; and twice there were sudden jerks of the steering wheel and truck but no warning message. I have reported each of these incidents to the dealership. I also called Chevrolet Customer Assistance. I explained the problem and asked if they would assign a Field Service Engineer to assist the dealership. hey declined my request. Because I momentarily lose control of steering the truck, I fear for my safety and the safety of others.

Vehicle suffered a failure cascade of the brake booster vacuum pump system. During a low-speed bumper collision on July 4 and a boat ramp slide, the pedal triggered abnormal ABS-like pulsing as the computer tried to hydraulically compensate for dropping vacuum pressure. This resulted in truck front bumper damage and boat trailer fender damage. On July 10, total failure occurred in a drive-thru, rendering the pedal rock-hard and sopping mear impossible. All marked parts and logs are available for inspection. Onboard diagnostic data reveals the electronic brake control module has driven continuously without a master clear for 22,665 miles, locking the last system initialization to 78,468 miles. This continuous data loop proves code C0299-00 was actively visible in the history log during the subsequent dealer service visits. Instead of performing the hardware pump remedy under Recall N192268490 (the federal safety agency 19V650). At the Jan 24 dealer visit (78,482 mi), dealer applied a software update and charged out-of-pocket fees to clear symptoms. They also ignored subsequent communication regarding the billing discrepancy. Technicians completely neglected the history logs despite explicit complaints regarding low-speed ABS sensations, trailer brake messages, park assist, and brake assist warnings. The 2026 dealers (and 2024) falsified multipoint inspections stating brakes required NO service until after winter. Jan '26 dealer delayed further diagnostics until June '26. May '26 dealer ignored texts regarding a crooked steering wheel and unstable tracking after alignment service. The truck was intentionally misdiagnosed as functional to avoid the warranty period repair. This unaddressed mechanical failure caused a destructive system cascade requiring replacement of the vacuum pump, oil-contaminated vacuum lines lines, oil-saturated booster, master cylinder, glazed pads, warped rotors, fluid flush, tires from module drag, alongside the resulting bumper and trailer property damage.

Rear power window defrost thermal event. While rear defrost was on the plastic connector that goes to the rear defrost of the power rear sliding window began to smoke heavily. In 2020 there was recall number N192265660 for the 1500 series of the same year for the same component that failed and is a fire risk. 2500 had no recall but this vehicle contains the same product and poses the same fire risk as the 1500.

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

Truck will shut off then on rapidly when turning left. Alert messages on sensors come on and off as lights flicker on and off. Radio screen will go black randomly or not turn on. AC shuts off and on randomly as well. Very dangerous while driving and you are about to turn left if truck shuts down. This happens at least once a week.

Wheel will lock up randomly on slow turns like an intersection, parking lot or anything. It’s very random and there’s no reason why it does it. The truck drives fine most of the time. It will say stabitrack service on my dash then it will go away my wheel locks up so I can’t turn it anymore then it will release like 10 seconds after. I nearly been in two accidents from this. The dealership can’t find out what’s wrong with the truck and I don’t feel comfortable knowing it’s not fix.
