Best Car Buy Lemon, dishonest,stalling,untruthful Denver Colorado

My daughter who was 9 months pregnant needed a sounder car. She and her boyfried, he has no licence took their used car and was given a $2,000 credit and they also had $1,000 cash. she is 21 he is 23. They test drove the vehical and was happy. They signed the contract and two days later the brakes went out, the gas gage was not working, and the check light went on. They took the car back as it was the two days later and that was a Monday holiday and the dealer keep the car for 24 hours. They picked up the vehical and the following day she called back to ask them what they did and they told her nothing that she needs to bring it back again, by the way she did have her baby while the car was at the shop the second time. Her mother had to pick her up to take her to the hospital. They dealership had the car another 24 hours and said they fixed the brakes and the gas gage. The car now has another problem with the air pressure light on (they did add air the light is still on) and she needs to take the car back again. The problem I have is they sold a used car to a couple who, one has no job and the other no licence, and the car was said to have been inspected prior to selling it.
