Business ProfileforLone Star Mercedes-Benz

I took my *** *** here for a slight gear slipping issue. Nothing showed up on their diagnostics. So they then go on to take a transmission fluid sample that I never saw and tell me based off that sample that my entire transmission needs to be fully replaced for $15,000. The car had no symptoms like a check engine light, grinding noises or burning smells that are common with a major transmission problem. So immediately red flags are going off. They go on to talk me out of transmission flush which should be the 1st step in this situation, they instead insist a flush would make the car run even worse. So after this red flag, I wanted a second opinion. They give the car back running worse and with starting issues it never had before to the point it needs to be towed back, not only that the car has a damaged front passenger wheel. Finally get the car back again and take it to get that second opinion, I tell the new mechanic the minor slipping issue and he recommends that we start with a transmission flush, they go ahead with the flush completely fixing the cars issues 100% Almost a month later and the car is still running like new. I have since filed a complaint about this misdiagnosis that seemed outright intentional with intent to scam $15,000 out of a gullible customer with the dealership and with ******** ******, along with a complaint about my damaged wheel and $340 tow bill I was left with, I have basically been told tough luck and that the other mechanic only temporarily fixed my transmission and theyre standing behind their blatant misdiagnosis, which I should take their word for it. The dealership and ******** ****** continue to not take any responsibility for anything while my car continues to run perfect almost a month later, while the damage to my wheel and the tow bill were/are being completely brushed off and ignored. Easily the most unprofessional and dishonest establishment Ive ever set foot in.
