I don't drive the car much so just had my 6K service done at the dealership (purchased Ascent Touring in Dec 2018). Drove away and notice presets for XM are gone -- ? Then when pulling in garage noticed the beeps(forgot what this is called) to indicate approaching object no longer worked. What did the dealership do that turned these items off. I'm guessing they did something to the battery, and power to the electrical system was suspended for an amount of time that I now have to reset everything. Really annoying!!! Has anyone else experienced this??? I don't find the manual for the car very instructional -- they really need to have a non-technical person write the manual -- so it's going to be a pain for me to reset.
