The following Recalls were found on Kelly bluebook, that matched the issues I have been having with my vehicle perfectly. When calling the recall center, they stated my vehicle year 2018 Chevy Silverado and serial number were not listed for this but it's the exact diagnosis of what I'm experiencing. The Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash. As the vacuum level drops, the brake assists decrease, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash. What component or system failed or malfunctioned, and is it available for inspection upon request" The brakes inflate on their own as if someone is pressing them down while driving. The vehicle begins to jerk horribly causing the inability to steer or maintain control of the vehicle or the ability to stop. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes How was your safety or the safety of others put at risk? This is very dangerous. I have no control over the speed of the vehicle or if the brakes will fail, or if the brakes will burn up due to fighting with the accelerator while driving. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, the manufacturer inspected it and stated they could fix the issues, paid but then the same malfunction kept happening even after payment and supposedly being fixed. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" None related to the issues, Stabilitrak warning and then random hill assist to inflate the brake vacuum

The component or system that failed or malfunctioned, FUEL PUMP ( METAL FLAKING IN FUEL SYSTEM ) has caused 1 or more CYLINDERS to FAIL. It is available for inspection upon request. My safety as well as the safety of many other motorists was put at high risk due to the fact that I had a 40ft. trailer hitched to the truck at the time the engine power was reduced. thus causing my vehicle to loose power while driving on a major highway. The 2018 Chevy Silverado was diagnosed by the Chevrolet Dealership doing-business-as ASCHENBACH CHEVROLET located at 925 East Main Street, Wytheville, VA 24382. The vehicle has not been inspected by the Manufacturer. When pressing down on the gas pedal, the truck would not accelerate as normal, then a message appeared on the dash-screen ENGINE LOOSING POWER.

The vehicle has just completely died on me at least twice while driving it, the power steering keeps cutting out, and the headlights will dim significantly upon pressing the brake pedal or using turn signals. This has been going on intermittently for months. Upon an internet search, this does not appear to be an uncommon issue.

UNKNOWN The ignition, steering wheel, and electrical. While driving it flickers off and on, turns off the engine, unlocks my doors and turns on again. Yes, our safety as well as others are put at risk this can cause an accident to happen on the road while driving, most likely to get rear ended. Today it gave me a scare because my 2 year old granddaughter was in the truck.

Vehicle started to fill with smoke. I exited vehicle to look in the back seat when all of a sudden the rear window exploded causing glass to come flying at me. There was a recall for this exact same issue, however gm says this vehicle is not included in it. Obviously there are more vehicles that need to be recalled!

While driving down the highway, I heard a ding and the service trailer brake message appeared. Several minutes later, while driving about 30 mph and coming to a stop, I heard the ding again, the service trailer brake message appeared again, then all electric components died. I had no lights or gauges working, the radio turned off, the a/c turned off, I loss all steering capabilities as my steering wheel locked in place, and the engine died. All of this occurred while the vehicle was still in motion. As I pressed the brake and came to a stop, the electronics regained power. A message appeared telling me to lower and raise the driver's side window. I came to a complete stop. Even though the electronics returned, I had to restart the engine. I put the vehicle in park, turn it off with my key, then start it again with the key, all while stopped on a very busy highway. I was able to drive the vehicle home with no further issues. I have not contacted the dealership yet, as they are currently closed as I write this. I will be contacting them and informing them of the issue. I had mentioned a similar issue to the dealership a few years ago. They made a report of the incident, but said there is nothing they can do if they cannot replicate it. This is very dangerous. Losing all electronic functions, including the ability to steer and having the engine die while driving is scary. I can lose the ability to guide my truck and crash the vehicle into something or someone. This puts my family at risk and anyone else on highway that may be in proximity. There is no telling when this will take place. I have had electrical issues randomly happen while starting the vehicle, but not while driving. I may go weeks or months between electrical startup problems. My vehicle is available for inspection upon request.
