The central control screen goes through a rapid, seemingly random series of "ghost touch" control changes. It cannot be stopped or shut down. It often changes the language of all screens in the vehicle (I cannot read French), shifts the instrument panel screen from speedometer to any of a large number of random screens, changes rear camera settings or deactivates it, changes bluetooth and telephone settings, and any of dozens of other actions many of which have a direct and immediate impact on vehicle safety. It serves as a terrible driver distraction because the driver has to do whatever they can to keep the screen from making unsafe changes to the vehicle settings. The driver's attention is divided between whatever the screen is doing and what is happening on the road.

Constantly getting a message and beeping to service my trailer brake system while in park and driving. I-??ve never used this before for towing any trailers or anything. This message and beeping cause a distraction and i find it to be dangerous. And the fact I-??ve never used this is quite annoying.

2017 GMC Canyon with 77,000 miles, key does not come out of ignition when shutting vehicle off. Key is 'stuck' in accessory mode and will not turn all the way to allow it to be removed. Have to restart vehicle, then shut off, and maybe key will come out. This issue is reported frequently on internet forums as a problem with GMC Canyon and Chevy Colorado vehicles.

Vehicle stalled when I was making a left turn onto route 23 from route 296 in windham NY. Car shuttered and stalled. Almost got T-boned by a semi. Extremely lucky that I was able to roll backwards onto the bridge behind me. I did go online and saw that were other owners with the duramax diesel that experienced similar problems. This could have been a fatal issue. I'm actually worried about driving this pick up. Contacted the dealer and they told me without the error code they couldn't help me. Disconnected the battery to clear the check engine light. Any suggestions?

I had 4 loads of mulch loaded in my 2017 GMC Canyon in early June 2019. Some mulch fell between the cab and cargo box where it smoldered on top of the truck gas tank for weeks until it melted tubes prompting onstar to send me two emails 6-27-19 and 6-29-19 to see my GMC dealer within 7 days for "an issue with the emission system". the dealer ignored my first visit and may have ignored the second but now the vehicle would not allow me to pump gasoline due to a melted tube and other parts on top of the fuel tank. I discovered that the gap that all pickup truck have, had nothing to direct mulch away from the fuel tank. If I had any idea this was happening I would have covered the gap with a tarp while having mulch dumped in. I feel very lucky to be alive. My wife and I took a long drive and the truck then parked in our attached garage while we watched tv a few feet away. I can't help but wonder if this is the first time this has happened or have many been killed in mysterious explosions that destroyed the evidence.
