In january ( 4 months ago) I purchased a used 2006 cadillac cts from Massey Cadillac. It had 103,000 miles on it. Less then a month after I bought the vehicle, which happened to have a clean history, I had to take it to the shop for what turned out to be bushings.Fine whatever, after 100,000 miles I can expect to change out some things. But last week my car started to basically break down. When I get on the gas it makes a horrible stuttering noise, and randomly jolts when I'm driving. I've noticed that the noise it is making has gradually gotten louder and has been there since I bought the vehicle. I found out today that I have to replace my camshafts because it is causing 4 out of the 6 cylinders to misfire. The problem has been there all along and i'm pissed. Apparently a woman can't go into a car dealership and trust the people working there to sell her a car that works. I didn't know it would be necessary to have to bring a mechanic along who could comb the car and make sure that I wasn't being sold a lemon. So now i'm facing $2500 upwards in repairs in a car that I have owned for LESS THAN FOUR MONTHS. I am so angry and I feel absolutely taken advantage of.
