The idea that you see dimming lights could either be the result of lower RPM's or there could be an issue with the charging system. Newer vehicles are extremely reliant on proper voltages. If they get too low, anything can happen.
Do me a favor. I need you to check the alternator output when this happens. Here is a link that shows how to do it. All you will need is a voltmeter or a multimeter.
Make sure that when this is happening, that the RPM's aren't dropping too low.
One other thought is to have the can-bus system scanned. CAN stands for controller area network. This network ties several computers and modules together via a few wires. Here is a video that shows how it is done. Note that this scan should identify any of the modules containing codes and if there is an issue within the can-bus system.
Let me know what you find or if you have other questions.
Take care and God Bless,
