Huffines Hyundai Plano

2nd time to buy a car from Huffines of Plano. Bad experience with Mr. Ray Huffines,general manager, and the service department. This is 2nd time the dealership has had my car to fix the problem. The service department has had the Sonata for over 2 weeks and still can not find a solution. They installed a new electrical unit and the light still came on. On Monday a Hyundai tech is coming out to take a look, good luck... I spoke with Mr. Huffines on Friday and he kept insisting he was confident the problem could be fixed and to me brushed off the whole situation, maybe because I am a female. I maybe a female but I am a knowledgeable consumer. I have forwarded Mr. Huffines my emails to the general manager. I spoke with the general manager as well that day and told him I wanted either my down payment back or a different car. His only reply was let's wait and see. I am tired of the wait and see attitude cause their attitude is indifference. I was told I would have a loaner car and the service tech could not even do that right. I had to speak with the sales manager concerning the situation. The service tech expected me to drive my car with the light on. I did not purchase the car with TPMS light on and I can't believe they expect me to drive it this way. Please do not expect any satisfaction or that the delaership thinks customers are #1, cause clearly by my experience they do not care after they sell you the car...........
