On multiple occasion the dash controls will freeze buttons will not work and touch screen will not work I took it in to the dealer and they told me that nothing is wrong with the vehicle. But every now and again it will freeze up the only way to get the control to work again is to pull over and turn the vehicle off and on.

I just left work, my truck was parked for 8, hrs. After 3, minutes of driving the service stability track light came on. After a couple mins. I turned down a major highway and then the following warning lights came on: Check engine, low fuel ( it was half full), traction control, drive with caution, strearing assist off. The electrical panel went crazy and I lost power to the engine. I pulled over and called Chevy roadside assist. They towed the truck to cox Chevrolet, where I purchased the vehicle brand new only a year ago. They could not duplicate the issue and I had to drive it back home. This is clearly a malfunction. I do not feel safe driving the it.

Truck shakes at speeds above 55 mph. At 65 mph my phone will fly off the magnet mount on the windshield; water and ice shake as if boiling at 70 mph and above. Sometimes the vehicle feels like it is coming apart it shakes so hard. When the vehicle was two months old it stopped on a city street in arlington va and was undriveable. After a timeout period of 10-15 minutes it was driveable but at 10 mph it whined as if the transmission or engine was going to blow up. At 20-25 mph it was a screaming demon and had to be towed to the dealership (browns) who found no record in car computer system of fault. Battery or electrical system was completely dead on 7 June 2019 with about 10,200 miles. Dealership knew I had appointment and I asked for tow but they don't provide a tow from reed-lallier. Onstar was of little help so I called my usaa insurance roadside assistance to get truck jump started; I missed appointment and they canceled appointment that morning which was to check for shaking and also 2nd oil change. Gmcustomercare took my concerns and asked my resolution which was check battery for bad cell, be aware of first transmission problem in arlington va and the current problem of vehicle shaking. I am a retired paratrooper with verifiable severe nerve damage to my back and lower legs and this vehicle causes serious physical and neurological problems when driving highway speeds.

Brand new 2018 midnight edition Chevy Colorado less than 24hrs on the engine and had less than 900 miles on it. Went to go to work one morning and it wouldn't do anything. No revere. No power steering. All lights and gauges were flickering and going crazy. Engine was chugging and making odd noises.it would not move from my garage/driveway. Had it towed it to nearest dealership. Over 2 weeks of diagnostics it's either a steering module or a wiring harness part. Dealership tells us its faulty wiring/steering module. It is an intermittent issue and it's hard to diagnose. I really feel that this could cause many safety issues since power steering was completely out and it wanted to shut off on us. This could have been bad if it happened while we were driving it to work. The dealership we purchased it from had done some electrical work but did not disclose what was done until it quit working and was brought to a different dealership. They brought it to our attention when it was towed in. The wiring that was done before purchase is what's causing all issues electronically. Truck is currently in the shop waiting for a part that is on backorder. Waiting for paperwork after repairs are completed. If they can be completed. They're still trying to fully understand the electrical issues since it is so random. It has been in their shop for over 2 weeks now. I just want someone to be aware of these issues incase it needs to be recalled. This could be a scary issue if it happens while driving.

The display for the backup camera is on at full brightness. There is a control knob to dim the interior lighting and display, but when the vehicle is put into reverse, the display goes to full brightness and cannot be controlled by the brightness control knob. At night, the passenger side mirror is not useable since the backup display is so bright. This almost resulted in accidents when backing up into a parking spot.
