I had a Dodge dealer replace the tie rods on my Custom Dodge van a few years back... I left on a trip to Nevada the next evening. I did not know it, until I got 200 miles away and found they left the tie rod bolt collars completely untightened and flopping in the wind. I was out in the middle of nowhere and it was 12:00 am in the desert. The front wheels had crossed on me (completely towed-in severely). My wife was with me so I had a witness. I took a wrench and a flashlight and fixed it myself. Both tie rods. When I got back home, I went back to the dealer. I tried to reason with the a-hole manager and got nowhere. I exploded in a rage.
I left though before anything bad happened. I took it to small claims court and got the labor money back in a settlement.
By the way, they told me I did a perfect job when I aligned my front wheels, out in the desert on my back with a monkey wrench and a flashlight.
I have many stories to tell about car repairs, car dealers, new car purchases going bad. It doesn't matter who you deal with, it's a jungle full of good and bad services out there. If you are poor or of little means they will screw you and try to get away with it.
