2000 Chrysler Intrepid review from North America

I purchased this car from a private person, and within blocks of driving the engine light came on. I stopped at a service station and the guy there said, oh its probably nothing because it sounds good. 2 weeks later, and a new oxygen sensor, and it has to go to the shop today, I came on line and see that my car/lemon suffers the same problem listed many times here. Engine light on, oil light flickers on, and more money down the drain, and I am making a bank payment on this. Pretty sad that this company allows this mediocrity and then complains people don't buy their product. I would like to know if there is any way for me to make the company accountable, any suggestions/ for me or my mechanic? Thanks, please contact me at dardem90@hotmail.com.
