1st occurrence, 9840 miles- slowing to stop sign, about 10mph, truck jumped violently, felt like I was rear-ended. Service parking brake, service ESC, traction control off messages and cel on. Stuck in gear. Restarted truck, resumed normal operation but cel remained. 2nd occurrence, 9865 miles - 65mph on highway going around curve, truck jumped violently causing rear end to break free slightly, though I kept control. Transmission now several gears lower and stuck there, turning 2400 RPM at 65mph. Same three warning messages and cel. Tried manual transmission mode, but it displayed no gear indication, and the +/- buttons did nothing. Pulled off highway, restarted, all messages went away, cel remained. Truck resumed normal operation. 3rd occurrence, 9905 miles (on the way to the dealer) - I was stopped at traffic light, first in a string of cars. Light turned green, I started to accelerate, just into the intersection, truck jumped violently, same warning messages, still had the cel from the last time. Truck was now stuck in a higher gear, could barely get through intersection. Vehicle behind me narrowly missed rear-ending me, and others were blowing horns as I limped to the far side of intersection. This is a massive safety concern. If any of the above scenarios had occurred on snowy/icy roads, I could have injured or killed someone, including myself and/or my [xxx] year-old. Dealer replaced tcm, but is still noting "loss of communication" codes being generated. A Chevy engineer has requested them to investigate the wire harness for damage in a particular location, suggesting Chevy knows of a manufacturing issue. If that's so, and Chevy hasn't issued a recall - or even a tsb - then this poses a strong case for negligence on their part. Are they waiting for someone to get injured or die before acting on this? I've now been without the truck for 10 days.

I have a 2020 Silverado 1500 lt trail boss with just over 5000 miles on it with one previous recall which was completed. On this occasion I was traveling on the highway at roughly 65mph when alert sounds came on followed by a message on the cluster saying to shift the vehicle to neutral and push start button. I did that and there was no response. I was in the fast lane and did not have enough speed to get to shoulder so I pulled to center turn lane of highway to stop. I attempted to start the vehicle several times over 5-10 minutes with no response. Cluster gauges would cycle like when vehicle is started, but it did not engage the starter. I also tried to remote start from key fob with same response. There was traffic traveling at high speed in opposing direction on either side so it was unsafe to inspect the vehicle. I used onstar to get roadside assistance and about 15 min later police showed up to provide assistance. Onstar said it would be close to an hour for a tow, but police got me one about 15 minutes later. Luckily Texas cops are pretty cool so we just hung out until tow truck arrived.

The following all takes place while driving the vehicle on the interstate and city, at higher rates of speed and when traveling at a slower speed - which is an extreme danger - every dash warning light came on and warning messages flash (brakes, steering, trailer, fuel, etc) roll from message to message, brakes get soft and hard to stop, truck tried to stall and slowed down like it was losing power (this happened while rolling at 45 mph), ac stopped working (fan working but cold air stops), truck lunged forward while engaging the brakes to slow down at a red light, steering definitely stiffer due to lack of power assist. These same messages and warning lights will also continue to flash when the truck is parked. This issue started at 3300 miles on July 8th, then it happened again July 24th, then again Aug 4th/5th.

This vehicle was delivered to me in late March 2020. New smyrna beach Chevrolet sold me two faulty vehicles. The first they took back and now this second vehicles back up camera works intermittently from day one. GM nor the dealer ship can locate the replacement part and this has been on-going for 3 months now. I do not feel safe driving a vehicle that has a faulty camera. I fear that as a result, bodily injury could result to someone else. GM has failed to give me an eta on the part, failed to put me in a loaner vehicle, and failed to resolve the problem by offering adequate trade assistance to get me into a working vehicle.

Brand new truck with only 450 miles. First incident was check engine light came on, brake pedal was really hard to press almost hit car infront of me. Second incident all lights came back up ABS, SRS, trailer brake module, parking brake, truck will not go faster than 42mph. And brake pedal was really hard again. Call onstar for a diagnostic and code came up, C05B0, P25A2. Check engine like came off. Went to dealer today and they said nothing can be done, because no light is on. Service advisor refuse to put scanner to read any stored code. Service advisor say it can be the computer is resenting, need to keep driving veh until check engine light comes back on again. No feel safe on new veh with no brakes twice.
