NHTSA Complaint #11623008 — 2006 SUZUKI RENO

I just bought a Used 2006 Suzuki Reno from a private seller 3 months ago. It has less then 53,000 miles on it so I thought I was getting a great deal. While driving it at night 3 weeks ago, I had my lights on high beam. A car was coming towards me so I flipped the light switch on my steering column. Which is also the blinker switch. And we almost wrecked head on with each other because when I flipped the switch to go to low beam there was no headlights. None whatsoever on low beam. I have driven on my street testing it to make sure it wasn't a 1 time thing. Or possibly my fault. If I have the low beam lights on when I first turn the lights on they work but go dimmer and dimmer as time goes by. And as soon as I flip the switch whether it's from High beam or low beam it's completely dark. No lights on low beam at all after flipping switch. But they work on high beam. I took it to my mechanic and he said there's a short/problem in the headlight switch/blinker switch on the steering column. I can't/don't drive it at night or anytime after 6pm to be safe. Also my mechanic has had to clear the driver side airbag light that has come on my dashboard 2 times. 1st time he thought it was because the service ingine light came on. He had to replace the cam shaft position sensor. Only a week later the airbag light came back on the dashboard. So off to the repair shop I went again, costing more money. He said he was able to clear it. But not for long. 3 days later it was back on. So I checked different options and took my car to a different repair shop. I was told then that this make and model car had issues with the airbag wire harness from the steering column all the way to how the wiring was ran to the front driver seat how it's to be connected under front driver seat. Causing damage to the airbag sensor & module. Son sold car to me after mom died. Told there's recalls for both, didn't know it or have done. 1 site said yes to car recalls another said no. ??? Help Please...
