2016 Chevrolet Silverado 1500

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 (NHTSA 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.

Doors automatically unlock while driving or parked and not running.

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.

Transmission started shifting hard, shuddering in torque converter, and long time shifting into 1st gear. Took it to a Transmission guy and he said it needs a full rebuild and is very common with this Transmission in this truck.

Had steering centering go out. Data cable pinched or broken somewhere in system and transmission got out. Also 4x4 system went out.

Brake assist activates for no apparent reason

The AFM code p3400 was activated on the truck and the lifters went bad and caused damage to the cam shift. Lifter failure which caused fuel to shoot down exhaust and burned out the catalytic converters. Dealership wants 10k to fix not including the catalytic converters.
