2014 HYUNDAI SONATA Seats Problems

The electrical in the entire car is malfunctioning. Sometimes the brake lights don’t work due to wiring, other times the seats control don’t work and the cables to battery is not connected/firing correctly. Has an entire electrical issue

The driver's seat lost a bolt and the seat was no longer bolted down at the back, although sitting on it would lower it. I took it to a mechanic and they re-attached the screw and bolt but were unable to do so in a way that the seat operates properly. It still lifts when I get out of the car and lowers when I sit down. This is available for inspection if needed. The safety concern is that in the event of an accident, the seat may detach from the base of the car. The problem has been reproduced by an independent service center. The work was done in Feb 2022. The vehicle hasn't been inspected by any others. There were no warnings or other symptoms before or after the event.

Left driver side rear and front headlamps would burn out, after time noticed the left headlamp flickering 9n and off while driving at night in auto mode, also inside dash lights dimming, also left driver side seat will not adjust, this is a Hazzard for myself and others while driving at night, with lights malfunctioning, was pulled over by highway patrol, and given a warning to fix headlamp.Issue has not been inspected by anyone and the vehicle can be inspected upon request, no dash or warning lights have came on.

Dash cracking severely over Airbags...Hyundai refuses to address the problem even though they had a PRIOR RECALL for the Same Issue. The Spiderweb Cracking is severe enough I am concerned my airbags will deploy without warning. Leather in Limited Model Seats Cracks and Disintegrates so badly the Power Motor and Components are exposed and compromised.
