At slow speeds, such as when parking, the truck's electrical system shuts down, I lose power steering, dash lights, radio, and then the truck restarts itself and continues. This has happened multiple times and Chevrolet dealers don't w what the problem is. If nearly collided twice due to lack of power steering.

While driving on 30-40mph and hit the brakes slowly, it feels as if the pedal is gonna fall off and can also feel a vibrate on it. It also stalls as if the brakes are being pressed but I'm not, this happens usually in the beginning after being turned on and then stops doing it after reaching the middle of the temperature.

I started my vehicle and put the truck in reverse to back out of a parking spot. Gave the truck gas and it wouldn't accelerate. Put the truck back in park and looked at the guages and there were no RPM's showing on the cluster and the oil pressure was at zero. There was a message that said trailer brake system on the screen. I turned the truck off and on again and the same thing happened. I put the truck in drive and it would move forward but the motor ran very rough and there was no power steering. I dismissed the first message and another message popped up that said "steering assist is reduced, drive with care." I pulled into another parking spot, turned the truck off, and waited for a ride. I started the truck when my ride showed up to make sure it was still not working and it was as if nothing happened before. The truck had no issues on the 16 mile drive home. Got home and turned the truck off and started it again and the message came back up and the issues came back. I have a video of the trailer brake system and me shifting the truck and the guage cluster. I have a picture of the steering assist message.

While driving 41-60mph, the truck starts to idle as if the brakes are being pushed on one tire and the brake pedals and gas pedal tend to vibrate as if it were to fall off. After awhile doing that, the stability control light message comes on after reaching the middle of the coolant temperature and the problem goes away. Seems like it does it when it's on low temperature.

I have filed a complaint already about my 2018 silverado1500 L, never received a response about the complaint filed. My truck road very rough, it had a bad vibration and shimmy in the front end. The front end would nose dive when braking. The truck would pull to the right when going around a right curve. The left front tire was riding on the outside edge. Taking to long to get the truck to stop when braking. These complaints were ignored by the GM service centers, I was pretty much called a liar. The left side front tire edge was very visible to the eye on the tire riding on the edge. Called a liar again. At 16000 miles I took matters into my own hands. I bought new shocks and struts and had a certified service center put them on. The truck rides well, no more shimmy in the front end, the steering is fine going around a right-hand curve does not pull to the right anymore. The truck is now braking like it is supposed to. I have a warranty on this truck the dealerships denied that anything was wrong with the truck. Why when I had the shocks and struts changed the problems went away. I keep the GM shocks and struts. I took a strut and placed the rod end on a board and pushed down on the tube the rod went into the tube with hardly any resistance they were junk. I am going to make a video demonstrating the GM strut and send it to the news media along with the paperwork showing where I had taken my truck to the dealership service centers. If GM is not going to honor their warranty and tell their service center techs to lie about the problem the public has the right to know. I am going to put the date that I had the shocks and struts changed on the next step.

Loss of power steering assist when first starting the vehicle. A message is displayed on the info panel in the center of the dash and all steering capability is lost. It's impossible to turn the steering wheel when this happens. Both times the vehicle has been stationary and I've been able to correct the problem by disconnecting the battery and then reconnecting it. I've reported this issue to the local Chevrolet service center and they told me to continue monitoring the problem. I'm obviously concerned that this will happen when I'm driving, since, like I've already mentioned, you completely lose the ability to turn the steering wheel. Other messages pop as well. "traction control system requires servicing." "trailer brake requires servicing." Many of the electrical features on the dash quit working.

Driving back from the holidays in another state. Stop to get gas, I check tire pressure and put fuel additive in the fuel tank. I get back on the highway, going the speed limit which is 75 mph. All of a sudden the steering gets tight as I was next to a rolling semi. I stop at a rest area to see if I can find any visible problems but I could not. At lower speeds the problem seemed to be worse. High speeds the steering was tight and trying to switch lanes it almost feels like the steering locked. About 25 miles later the problem. Seemed to be better but eventually came back and the next day it was bad again. The highway I was on (I20) was recently re done so it was smooth road. I've done research and can only assume it has something to do with the eps system.

2018 Silverado crew cab lt has had a stiff steering issue for over a month now. Has 11 thousand miles. Carried to lynn layton Chevrolet the first time, found 0 issues. Carried back a couple of days later, service manager drove the truck and said he experienced the stiffness while driving. They replaced the battery stating their was a dead cell in the battery when I've never had any problems with starting vehicle or dimming light. I picked the truck up again still has same steering stiffness while driving and turning right and left. Took the truck back a third time the same day as my second attempt to fix and lynn layton Chevrolet in Decatur, Alabama still has my vehicle. Seriously consider trading at this point to avoid any more conflict.

Shaking in the front at speeds over 40mph when there is a slight acceleration, that does stop when you take the foot off the gas. The shaking seems to get more violent at higher speeds, and so far the dealer has been unable to find the cause.

Driving at highway speed holding the steering wheel straight the truck will move quickly to the left lane some time and then other times to the far outside of the right lane. Also I have had it move all the way to left lane and the all the way back across the right lane to off the road. Have notice as well that you can be turning the steering wheel to the right and the truck is still going to the left. When driving in a curve and coming back to center from the right it will snap back really fast not nice and easy like from the left. The truck has done this from day one I have tried to get GM to fix it but the say there nothing wrong I have drove 7 other truck like mine and they all had like there should the drive straight down the road.
