I recently purchased a new 2019 QX30 and I really like it but it has a quirk that I find annoying. If I shut the vehicle of and get back in after shopping, the audio system is on and on the same station it was on when I shut it off. However, if the car sits overnight, the audio system is off when I start it in the morning. I have to then turn it on and reset the station. I talked to the service manager at the dealership and he said this is normal. Can this be?? I've owned cars for 55 years and have NEVER had one that did this. It does not have Bose, but it does have NAVI. Any body elses doing this?
