UNKNOWN I had performed preventative maintenance this evening, fuel filter replacement and noticed after I pulled the fuel filter from the housing and tipped housing back upright, there was what appeared to be brass/gold metal shavings in the bottom of the housing in a little puddle of fuel. If there is metal shavings in the filter, that is a problem. Not sure if it would be fuel pump, or lift pump. Truck runs fine, I do get some hesitation from time to time, but not always. No warning lights/indicators, no water in fuel indicator, or presence of water in fuel. I am worried about safety if metal shavings contaminate entire fuel system, plugging injectors shutting down the truck on the interstate.

For about a month I heard a clunking sound in the steering wheel shaft when I initially started the vehicle and turned the steering wheel. After a few miles of driving it would go away. The vehicle then began to have a hesitation when I would try starting it. Diagnosed as two cells were dead in the battery. Replaced the battery and the steering improved. Two weeks after replacing the battery, I started the vehicle and started to turn out of a parking spot. At that time the steering wheel refused to turn and it sounding like a pump going out. The service steering warning came on. I got it to the dealer and they diagnosed the electric rack and pinion drive belt had broken and sheared the gears in the assembly. The vehicle is a 2018 Chevy 6.2L High Country with 71,000 miles. I was told by the dealer that if this would have happened while driving at highway speed it would have locked the steering wheel in the position at the time of component failure and would have more than likely resulted in a crash. Currently the vehicle is still at the dealer for the last month waiting on the rack and pinion to be shipped. Apparently there isn't any of these parts anywhere in the United States.

Under light to medium load on the throttle, the transmission will shift very hard from 1st to 2nd gear and sometimes 2nd to 1st while decelerating. Another issue is that the transmission or torque converter will shutter, but that is not as often. It does not happen every time, but happens way more often than it should for it being a 2018 with 26k miles. The GM Authority website has this as a known problem, but my VIN is not associated to it for some reason. Apparently flushing the transmission with Mobil 1 Synchromesh fluid can solve the issue. The truck seems to hesitate while taking off something and I think it is related to this transmission issue which can be a huge safety risk.

During the mornings when first starting my truck, I get a stutter or hesitation to the engine when accelerating out of my driveway. This happens just about every morning. I have determined that the truck has to be off for about 10+ hours. The stutter/hesitation goes away after the car warms up in about 1 mile. Have had the truck into the shop but they can find NO problems.

I purchased a certified pre-owned 2017 Chevy Silverado on June 6 of this year. On June 13th, on my way back from a 10-hour trip, where I was towing a trailer with a car on it, my trailer brakes suddenly stopped functioning (about 4 hours from home). Not only did the trailer brakes stop functioning, but a warning message popped up on the dashboard "service trailer brake system". But this warning message didn't pop up just one time, it kept coming again and again and again and again and again, relentlessly chiming and distracting me from driving, it covered my speedometer readout, it prevented me from receiving or making voice commands, prevented me from hearing phone calls, and prevented me from listening to music. The service warning chime also prevented the turn signal chime from functioning. So for a full 4 hours, I was constantly reminded with a service trailer brake system chime, was unable to hear my turn signal chime, was unable to listen to music or make a phone call, and was unable to see the digital readout of my speed. The vehicle had been rendered completely undrivable, and I absolutely will not hesitate to say that the vehicle was not safe to drive in that condition. Especially if you consider that I was towing 5,000 lbs with no working trailer brakes. Your vehicle's defect endangered my life.
