The front left frame that the wheel and suspension bolt onto is in advanced rust stages. It is being considered unsafe to drive although the right side is still considered safe. Common issue from what I have heard. Took car in to replace the starter and shop doesnwant to work on it. We cannot afford a new vehicle because of a knkwn weakness in the frame work

I bought this vehicle under the impression that I was being sold a good safe vehicle for work and my families needs are also a priority. I never test drove the vehicle till I drove home after purchasing it. Not even 4 mins on the road and I noticed the ABS light came on the dashboard with the brake light and the front brakes began to smoke. I contacted the dealship but was disregarded and not offered an exchange or any type of solution for my problem I even explained my job required me to use my vehicle for transporting material for work and since I was in charge of 4 people that woul be requireing skills for customer service and making sure all customers were satisfied. Pacifi northwest motorsports took advantage of my impariment I feelscammed and I want to have my money back or at least exchange for the value of $10,000. I was never offered any type of sloution from the bussiness the owner laughed at me and said that it sucked to be me and hung up the phone on me. The bussinness owner lied to the attorney generals office about offereing me a remedy the only remedy I would consider is my money back and an exchange for my troubles I feel that this is a vehicle manufacturer malfuncunctiom. I'm still having the sa,e problem with my brakes .. Please help I have tried repairing the problem, numerous times to be unsuccessful .
something shorted on or behind the dash on the drivers side and caught fire
My passenger side wheel broke and went sideways when I turn off the highway in montzuma only going about 30mph
I had a crack in the windshield and when they replaced it the technician said it was so rusted from the inside that if anything happened again they would not replace it he had to really do some work arounds he said to even replace this one. That makes me feel that this is a real safety issue if we were to get in a serious accident. There is no rust on the outside around the windshield at all. So I was very surprised when the technician told me that.

Fuel gage shows half a tank but I ran out of gas. Lights blow all thetime.
Abs light keeps coming on while driving
While driving at low speeds, about 20 MPH or lower, the brake pedal fades to the floor. There are no lights or codes and brake fluid at the proper level. This happens quite frequently and anywhere.
