2016 Chevrolet Silverado 1500

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.

Vehicle: 2016 Chevrolet Silverado 1500 Component: Powertrain – Automatic Transmission (8L90) Manufacturer: General Motors (Chevrolet) I am submitting this complaint regarding recurring transmission problems with my 2016 Chevrolet Silverado 1500 equipped with the GM 8L90 eight-speed automatic transmission. I am concerned about the vehicle's inconsistent shifting behavior, the repeated failure to resolve these issues through service, and the potential safety implications of unpredictable transmission performance. My truck has been taken into the shop multiple times because of transmission-related concerns, including hard shifting, intermittent and inconsistent shifting, and transmission shudder. Despite these repeated service visits, the problems have continued. During one of the repair visits, the transmission wiring harness was replaced. However, the shifting concerns persisted. I was subsequently told by the service personnel that the hard shifting and intermittent shifting were “just how the transmissions on these are.” I do not consider this an acceptable resolution to a recurring mechanical and drivability concern. I was also informed that GM introduced updated transmission fluid intended to help address the transmission shudder, but that I would have to pay for the fluid service myself. I have been left facing additional expenses for the revised fluid, a potential torque converter replacement, and other transmission upgrades despite the repeated repair attempts and the continued existence of these problems. My primary concern is the transmission's inconsistent operation and the possibility that unexpected or severe shifting behavior could affect the driver's ability to control the vehicle safely in certain driving situations. Depending on the circumstances, unpredictable shifting, hesitation, or abrupt engagement could create a hazardous situation when accelerating, merging into traffic, navigating intersections, or driving in congested condition

"While driving, the vehicle experienced a sudden and complete loss of propulsion/acceleration due to internal failure of the 6L80 6-speed automatic transmission. The failure occurred without prior warning, creating an immediate highway safety hazard by leaving the vehicle unable to maintain speed in traffic. A professional mechanic diagnosed the issue as a catastrophic torque converter failure that contaminated the entire transmission system with metal debris, requiring a complete out-of-pocket rebuild." This resulted in having to pay $4,800 plus tax in such a rough economy.

I had noticed that my a/c was not cooling due to refrigerant loss. went to dealer and was told that I needed a new condenser and that my original was out of warranty & no recall was in effect. I was charged $1600.00 after the replacement was installed. I asked to see my original condenser & was directed behind the shop & low & behold there was a pile of 30 condensers exactly identical to mine

The contact owns a 2016 Chevrolet Silverado 1500. The contact stated that while attempting to make a left turn from a complete stop, the vehicle lost motive power while depressing the accelerator pedal and was stranded in the middle of traffic. No warning lights illuminated. The vehicle was placed in neutral(N) and pushed to the shoulder of the road. The contact's husband arrived at the scene and restarted the vehicle; however, while driving at low speeds, the failure recurred. The vehicle was towed to a dealer, where it was diagnosed with metal shavings in the transmission. The dealer informed the contact that the transmission needed to be replaced. The vehicle was not repaired due to the repair costs. The check engine warning light illuminated. The manufacturer was notified of the failure. The failure mileage was approximately 120,000.

This truck is a 1500 Silverado custom with extended tail. There was a loud sound as if something happened , I moved to the shoulder and there was nothing visibly wrong. All tires had air in them, continued driving but did noticed a difference when I would back or turned to the right. Then days later one of my tires sort of was ruptured from the side of the tire and had to change tire. I put the spare and it is when I notice the bushing on both arms that hold the front wheels was loose. Looked for recalls and this model Chevrolet 1500 has a recall for front suspension arm bushing giving out and it is exactly what happened to my truck. The loud sound must have been one of them and then since most of the weight was put on the other bushing, made the tire give out and both bushings are not broken or torned so the bolt that holds arm and bushing is movable and loose, not holding the wheel the right way

For the past 2 years ive been having issues of losing power steering. Lots of parts and modules have been replaced out of pocket. Still not fixed. When it goes out it can be out for days to weeks and is extremely hard to steer. Its gone out or come back in during a turn which is very problematic and unsafe. I always get the same dash message, "service power steering drive with care". The dealership is aware and has seen the malfunctioning steering. So far the rack and pinion gear box has been replaced at $2700, then it was a terminal resistor that was replaced for $2,100, and several other trips in costing more money just to get the steering fixed but technicians have been unsuccessful so far despite their best efforts.
