Loose steering and sometimes steering wheel wants to return to center When this happens I loose all electrical - dash goes blank engine dies etc. the hot battery cable is very hot to the touch. I disconnected the ground cable and wait a few minutes and power returns This is going to cause a wreck if it is not corrected Local dealer says could be bad battery I had already changed it there is a place to say when this occurred it has happened several times over the last year the last 2 times were within a week

Vehicle had a "service ESC" and "service brake assist". Dealership said the master cylinder is bad and it is not safe to drive. Now its sitting at the dealership with NO eta on parts and no loaner cars.

My car has less than 8,000 miles currently. On June 5, I started my car and lights were on saying I needed service and maintenance. I believe it was around 4500 miles at the time. I took it in once, where I bought my car, they said it just needed an update. The next day, all of the same lights were on. Turns out, I need a new brake master cylinder. It’s on back order. I bought this car in April. It’s been in the shop for a month. This is ridiculous. - the notifications said I needed electronic stability control and service brake assist maintenance.

The valve body in the transmission failed at 28,000 miles. My name is attached to an additional same exact vehicle where transmission failed. These transmissions should be recalled due to loss of propulsion. The dealership service lots are full of vehicles with the same failed transmission

When trying to park car, vehicle will not detect the shifter is in park. If the car does not detect its in park it will not turn off and stays running hampering your exit from the vehicle. This is truly an unsafe condition due to not knowing how to get the car to shut down as well as not knowing if the car will roll if you do get out.

My 2018 GMC Acadia has had the "Shift T Park" alarm and indicator going off after my car is turned off and in "PARK" It only happens intermittently, but frequently enough to be annoying. The dealer and GM told me because my VIN wasn't in their recall range, they would not honor the recall. This has been happening since I purchased the car in 2018.
