general problems of the 2017 Volkswagen Jetta

I am continually have issue with my headlights bi-xenon ds3 bulbs going out. I have replaced the ballast and the bulb w oem parts and the issue continues. My day runner led lights work on the passenger side but the hid bulb does not work. I have no low beam. Everything else works. Same issue on drivers side until I replaced the entire housing unit. Regardless both lights do not reflect in distance making it extremely hard to see at night forcing me to have to drive w my fog lights on just to see.

The fuse that controls the exterior lights (tail, marker,etc. ) and interior lights at first interment would blow/burn out. Sometimes after a few days or a few months for the past year. In the past few weeks the fuse blows immediately once replaced. The car was brought to a vw dealer a year ago who changed the fuse and ran a diagnostic. It was brought back 4-5 months later and they again changed the fuse and ran a diagnostic. The second time was not given a slip indicating it was was there for the service and was not charged. While I understand no charge there is no no proof of service. As the fuse controls all the lights the car is dark at night.

Front left headlight has no power going to it. Rear right tail light has no power going to it. Third, brake light has no power going to it. Wind shield washer pump has no power going to it. Both rear doors do not lock. This issue is all connected with each other because it fixed itself. Once and they all came back on together and then it went back out.

I just bought a used 2017 Volkswagen Jetta gli a month ago, and the airbag light just illuminated this past Friday, along with no steering wheel controls working, and no horn. I called the place where I purchased it from, and they pretty much said OH well. This is a safety concern, as it affects the airbag. Is there anything I can do?.
