I bought a 2004 cadillac cts on March5 2014...The same night i bought it the check engine light came on so the ext morning I had it put on a machine...The catalytic converter was bad and it had a 5th cylinder misfire so i called them first thing that morning...My sales guy Michael said he would call me back because they had to make an appt with the mechanic(3 days went by no call)I called them back after the 3rd day and Michael tells me o the guy is here can you bring it?? I was unable to bring it right then,but he told me bring it Friday and i could get it Sat...Sat morning i called and he tells me o the mechanic couldn't get to it can I come back on monday or just leave it...I brought it back on monday and the guy repaired it... Few days later check engine light came on again and my car wouldn't start..I had it towed to cadillac repair and was told it needed a transmission flush and oil(warranty didnt pay i had to pay 245.00)..This was april 2 now on april 7th check engine light back on and i took it back to repair shop where i as told the computer was bad and the 02sensors needed to be changed,but the warranty didn't cover this(i picked it up and took it back to North Ga auto brokers) The owner came and told me he would take it for emissions (came back that it passed) so he said nothing was wrong just a filter needed to be cleaned...Drove the car home and a few days later while driving my car was running but not going anywhere!! I had it towed back to the dealership and they were very PASSIVE AGGRESSIVE and told me mechanics weren't free...The owner then said whatever was wrong he would have fixed but i would be charged the dealer fee to fix it smh....I then asked well how about i trade this back in and get something else(since i knew i wasn't getting money back) I was told i'd get 3,000 when I paid 7300...I then told them screw that just take it to mechanic....It was towed there at 930 and at 300 i hadn't heard anything...I called and was told the mechanic was working on it...They closed and i heard nothing!! The next day i waited till 12 and i was told the owner would call me because they didn't have mechanics number...I was like what dealership dosn't have the mechanics number?? This sounded fishy so i drove up there and then i was told o let me call the mechanic (the mechanic nobody had the number for) Now the owners brother told me they found out the transmission is bad and they can't fix it but i have a warrnty so it should be covered but they can't fix it because they aren't certified and the warranty wont pay them...I was pissed 7300 dollars and less then a month and now the transmission is bad!!??!! He told me o these things happen....Now the warranty is expired because it was a 3month or 3000 mile warranty whichever came first( i went over the miles due to going back and forth trying to get car fixed) DO NOT GO TO THIS DEALERSHIP!!!!! Now i'm out of 7300 dollars and i'm trying to get warranty to honor since i put miles on trying to fix car, but if they wont fix i gotta pay 1800 dollars for a transmission
