I got the run around from POHANKA Lexus, telling me the catalytic convertor needed to be replaced. I had the work done believing them and the next day the same problem reoccurred. They would not honor their work saying it was the other side, and it would be another 1500. Needless to say, I brought it to D&D and they did the REAL testing finding it was simply and O2 sensor. I will always use them for future repairs and suggest others to drop their dealerships and follow suite.
