I notice my car was acting funny Friday 12/20, it was having trouble starting after fueling and I noticed the rpm been go up a little and the car kind of hesitated at times but would go back to normal. It also had the engine light that would come on and off at times. I called that day for an appointment for Monday 12/23 at 2pm. The next day Saturday 12/21, my car wouldn't start but just crank. I had my car towed that day to CarX. I was planning on going through my car shield but however by time car x diagnosed what they claim what the reason and already repaired it prior to getting approval and making sure it was covered. I found out car shield was not going to cover it. I was livid. However car x ( Allen) told me it was a bad battery and a purge value in the fuel that was causing the issues. They wanted to charges me 250 for a battery but I knew better so I got one at auto zone but I was responsible for the purge value at 165 since they already replaced it however he told me my car was running perfect, I can turn my car off when getting gas now, engine light it off so I was ok with it. I really thought they fixed my problem. I had a new battery installed that night on my lunch break but when I got off a few hours later . As I was driving home the car seemed to run louder then it ever did and the engine light came right back on and I still had to leave my car running to get gas. I was so pissed. In the morning, before stopping at CarX I went to auto zone to have my code read and the battery checked, my battery was good and the code read an camshaft sensor. I had that code read on Friday 12/20 at auto zone when I noticed my car acting different, same code. Anyways, I went back to CarX and comforted them about my repairs. I was told my battery was no good at that time and now we just have another new problem. *** They repaired something that wasn't even a problem. They diagnosed my car by the symptoms and did not have the code read. I told them my car is still doing the same thing that they guaranteed fixed the problem. They also told me that they checked my camshaft sensor and it was good. Lies. They said to bring it back Thursday morning 12/26. But on Christmas evening, trying to leave for work, my car would not start. It would crank but not start. The exact same problem I had in the beginning that they guaranteed they fixed. I had to have my car towed once again back there today. CarX should be responsible for my repairs and needs to fix the real problem. I should not have to pay for another repair when I just got done paying for something that wasn't needed and was scammed. I really didn't even want to take my car back but they should fix my car the correct way and not google doctor my car repairs. Please take care of this. This has been a horrible experience especially during the holidays. I'm out of transportation now and I have my 13 anniversary in 4 days that I need to leave out of town.
