This has happened several time in the city crossing an intersection usually at slow speed braking and turning and all the sudden I lose everything. No steering electrical and braking. The park assist will sometimes start going off like crazy just before it happens, but not all the time. Put in park and open the door it comes back on. Then says roll down drivers side window and then back up. At on time I did have it happen on the highway. I was getting ready to pass and giving it gas and everything shut down for a split second and then took off again. This problem is going to get someone killed.

My truck has 30,000 miles and has the 'chevy shudder'. Why is this not a recall? Gmc wants me to pay out of pocket for the transmission flush. When I am driving the truck it begins shuddering and shaking through certain shift points.

Have had my vehicle at the shop for transmission issues several times. Two of the times, issues were duplicated and parts replaced, but same issues continue as soon as I get it back. My complaint when I take it in is always the same. Normally when I accelerate from a dead stop forward or reverse, the transmission makes a thumping noise. It has steadily gotten worse. A lot of times now if I take my foot off gas for a second, at faster speeds, and then put foot right back on gas, it makes the same thumping noise and sometimes a grinding noise like it's stuck between gears. This last time I took it to the dealer, was told there was nothing they could do and would most likely get worse as vehicle gets older.

While thankfully driving in the slow lane on the interstate in st. Louis my stability light came on the truck then slowed down on its own then went into four-wheel-drive then revved up to 6000 rpms then every service light came on on the dash when pulling to the side of the road the car then would not drive forward it stayed in neutral regardless of gearshifting it then began to cycle through all of the service request for the vehicle. After having to have the vehicle towed to the nearest dealership which was three hours away from my house they informed me the following morning the power steering control gearbox had went out and fried all the electrical's inside the vehicle. The vehicle has less than 39,000 miles after contacting gmc they told me there was nothing they could do that there was nothing on a recall list for my vehicles VIN number. After doing some research I saw that there was a recall for a very similar situation in 2018 in september. I have videos of the vehicle computer system malfunctioning if requested. I just wanted to document and file a complaint so this didn't happen to someone else and cause a serious wreck , since gmc has failed to recognize this serious of an issue.
