THE 2016 SILVERADO HAS A PROGRAMMING ISSUE FOR THE TRANSMISSION. WHEN I DRIVE UNDER A LOAD GOING UP A HILL IT CHUGS LIKE I HAVE A MISS FIRE ISSUE. THE PROGRAMMING IS SET SO IT STAYS IN THE HIGHEST GEAR FOR TO LONG WHEN DRIVING IN CITY CONDITIONS. IT STAYS IN 6TH GEAR GOING 25-30MPH AND WHEN YOU NEED THE THROTTLE. THE TRANSMISSION CAN'T DECIDE WHICH GEAR TO BE IN. ON TWO DIFFERENT OCCASIONS I WENT TO PULL OUT OF A SIDE ROAD ONTO A MAIN ROAD AND THE TRUCK FELL FLAT ON ITS FACE LIKE I HIT A KILL SWITCH AND IT ALL MOST CAUSED ME TO GET T-BONED. I HIT THE THROTTLE MULTIPLE TIMES BEFORE IT DECIDED IT WAS GOING TO 100% THROTTLE AND HAVE ME GOING OUT SIDEWAYS ONTO THE MAIN ROAD. I HAVE TAKEN IT TO THE DEALER AND THEY HAVE CONFIRMED IT TO BE A PROGRAMMING ISSUE, BUT THERE IS NO FIX FROM GM AND THE DEALER CAN'T DO ANYTHING WITH IT BECAUSE OF EPA LAWS, BUT THERE ARE AFTERMARKET TUNERS THAT ADDRESS THIS VERY ISSUE AND FIXES THE PROBLEM AND ALSO VOIDS WARRANTY OF THE TRUCK. IT'S HAD THE ISSUE SINCE THE 2ND WEEK I'VE OWNED IT FROM NEW. THE DEALER TOLD ME TO KEEP CALLING GM TO COMPLAIN, BUT ALL GM DOES IS SEND ME TO THE DEALER. WHERE I'M TOLD THERE IS NOTHING THAT CAN BE DONE. IT IS AN ONGOING ISSUE AND IS ONLY A MATTER OF TIME BEFORE IT CAUSES AN ACCIDENT OR DEATH IF IT HASN'T ALL READY. I HAVE 30 YEARS OF EXPERIENCE IN THE AUTO TECHNICIAN FIELD AND MY FAMILY COMBINED OVER 100 YEARS. YOU KNOW THE ISSUE IS BAD WHEN A BEGINNER DRIVER NOTICES THE ISSUE. IF YOU HAVE A LOCAL PERSON. I'D BE MORE THAN HAPPY TO TAKE THEM FOR A RIDE TO SHOW THEM. FOR WHEN THIS HAPPENED. IT STARTED IN 2ND WEEK OF JULY TO PRESENT. IT ONLY HAD AROUND 300 MILES WHEN IT STARTED.

VEHICLE INTERMITTENTLY LOSES ALL ELECTRICAL CONTROLS: POWER STEERING, ENGINE POWER, STABILITRAK, AIRBAGS. ALL ELECTRICAL SYSTEMS ARE COMPROMISED AND THE VEHICLE LOSES ALL POWER. ONCE THE VEHICLE IS TURNED OFF AND BACK ON A FEW TIMES IT WILL GO INTO A 'LIMP MODE'. I'VE BEEN STRANDED IN THE VEHICLE 4 TIMES. I HAVE HAD THIS HAPPEN TWICE WHILE DRIVING DOWN THE FREEWAY, ONCE DRIVING IN A PARKING LOT, AND TWICE WHEN FIRST STARTING THE VEHICLE. DURING ONE INCIDENT ON THE FREEWAY I WAS IN THE CENTER LANE AND LOST ALL ENGINE POWER, AIRBAGS, SAFETY CONTROLS, AND POWER STEERING. I WAS ABLE TO COAST AND MAKE MY WAY OVER TO THE SHOULDER. GM AND THE DEALERSHIP HAVE BEEN UNABLE TO RESOLVE THE ISSUE AND ARE NOW REFUSING TO HONOR THE WARRANTY, REPLACE THE VEHICLE, OR REFUND THE PURCHASE. THIS HAS BEEN A SERIOUS SAFETY ISSUE. I'VE HAD MY WIFE AND TWO SMALL CHILDREN IN THE VEHICLE WHEN IT HAS DIED ON THE FREEWAY. NOT ONLY IS IT A SIGNIFICANT DANGER TO MYSELF AND MY FAMILY, BUT ANY OTHER VEHICLES IN CLOSE PROXIMITY. AS SUCH I HAVE REFUSED TO DRIVE THE VEHICLE ANY LONGER, BUT GM SEEMS INTENT ON IGNORING THIS.

General Motors LLC (GM) is recalling certain 2015-2016 GMC Sierra 1500, 2500, 3500, and Chevrolet Silverado 1500, 2500, and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator, or the inflator sidewall may rupture.
Consequence & remedy
Consequence: A separated inflator end cap or inflator rupture can allow compressed gas to escape, resulting in the end cap or other components being propelled into the vehicle, increasing the risk of injury or crash.
Remedy: Dealers will replace the left and right side RRAB modules, free of charge. Interim owner notification letters informing owners of the safety risk were mailed on August 18, 2021. Owners will receive a second notice when the remedy is available. Phase I owner notification letters were mailed on May 5, 2022.

While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition.

During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
Consequence & remedy
Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017.

1PE18012 · Brake Vacuum Pump Failure
Opened Nov 20, 2018 · Closed Apr 10, 2022
Status: closed (inferred from source dates) · Service Brakes; Service Brakes, Hydraulic; Service Brakes, Hydraulic:power Assist:vacuum
On November 20, 2018, the Office of Defects Investigations (ODI) opened PE18-012 to investigate instances of sudden onset of a hard brake pedal that could result in extended stopping distance due to an issue with the brake assist vacuum pump in model year (MY) 2014 through 2016 GMC Sierra 1500 and Chevrolet Silverado 1500 series pickup trucks and MY 2015 through 2016 Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon SUVs.If the brake assist vacuum pump fails to operate as intended, the amount of brake power assist supplied to the driver can be significantly reduced, extending the subject vehicle stopping distance. GM stated that the root cause of pump failures was due to foreign debris such as oil sludge in the engine oil. GM stated that this debris can become trapped by the oil inlet filter screen. Under normal operation, this screen allows a small amount of oil into the brake vacuum pump. The foreign debris can, over time, clog the pump which can cause a loss of lubrication and a reduction in the amount of vacuum produced leading to a hard pedal and extended stopping distance.On December 13, 2018, GM issued a Special Coverage (N182202780) for the brake vacuum pump issue in MY 2014-2017 trucks and 2015-2017 SUVs on the K2XX platform for 6 years or 72,000 miles. Special Coverage repair includes the replacement of the vacuum pump and vacuum pump belt. Consumers received notification of the coverage via mail. On September 6, 2019, GM notified NHTSA that it was conducting safety recall 19V-645 which reprograms the electronic brake control module (EBCM) and included approximately 3.5 million trucks and SUVs. In October 2019, GM extended the terms of special coverage N182202780 to 10 years or 150,000 miles as well as now including the entire scope of recall 19V-645. In October 2020, GM expanded the scope of coverage N182202780 to include the MY 2018 Escalade and 2019 Tahoe.The remedy implemented in GM recall 19V-645 appears to be sufficient in addressing the safety-related concerns of this issue. Loss of vacuum assist now occurs at a progressive rate as well as there being a more timely warning of a brake problem to the driver through the driver information center (DIC). In view of the recall action and revision to the special coverage, this Preliminary Evaluation is closed. The agency reserves the right to take additional action if warranted by new circumstances. The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.
