The contact owns a 2013 Chevrolet Silverado 2500. While driving various speeds, the main operation system, calibration, speedometer, and start production were affected by cyberhacking. As a result, the contact stated that there was a complete loss of brake functionality and an erroneous speedometer reading on more than one occasion. Bentley Buick GMC (2120 drake avenue, huntsville, Alabama, (256) 415-6513) reset the vehicle with new calibrations and enhanced the engine oil life monitor to more accurately identify the required oil change interval, which produced diagnostic trouble code: 2T459. The failures recurred. The manufacturer was not made aware of the failures. The failure mileage was approximately 45,000. Updated 11/26/18

Silverado 2500 4WD 8-cyl

  • 20 miles
The contact owns a 2013 Chevrolet Silverado. The contact stated that while driving in first gear and taking the foot off the accelerator pedal to apply the brakes, the engine RPM's would not decrease and the throttle would not release for approximately 3-4 seconds. The failure caused abnormal forward movement from the vehicle. The contact also stated that while driving in first gear and shifting into neutral, the engine RPM's increased by approximately 200 ripens before decreasing. The vehicle was diagnosed at the dealer but the cause of the defect could not be determined. The contact stated that a representative from the manufacturer came to the home and drove the vehicle. The representative experienced the defect while driving the vehicle but did not identify the cause of the defect. The vehicle was not repaired. The failure mileage was 20. Updated 03/11/14 the consumer stated by the time his foot reached the brake pedal, the engine was holding a constant 1400 RPM, resulting in not only trying to slow the mass of the vehicle, but also attempting to brake against an engine locked at 1400 RPM. The consumer also stated that he removed his foot from the accelerator as a test and then popped the steering column gear shifter into neutral and the engine gained another 200 RPM for 3-4 seconds.

problem #1

Jul 282013

Silverado 2500 4WD 8-cyl

  • 1,500 miles
Transmission down shifts multiple gears when I decelerate. The first occurrence happened at 70 mph causing a very hard deceleration and near loss of control of the truck. I have had three other like incidences at speeds between 45 and 70 mph. These happened on dry pavement and I was able to slow safely. Had this occurred on wet or snow covered roads, I have no doubt there would have been an accident. 2. at times when I accelerate there is no throttle response for several seconds. When the engine does respond, the truck accelerates as if I have the throttle floored. Again this has happened on dry pavement. Slick conditions would have caused a spin out. 3. vehicle surges between 20 and 45 mph. Engine RPM continually jumps 200-300 RPM causing constant surging. Besides being very annoying, it would be dangerous on icy roads.
