I took my Tucson in to Service Dept because it was having difficulty starting and driver door wouldn't unlock. Bought the vehicle at this dealership and it has less than 30,000 miles. I also paid for the extended warranty - just in case. They charged me $136.41 for replacing the battery in the key fob. Battery cost $5.95 plus tax. Installation $130. I was told by the Service Dept that they had to "run diagnostics." All they did was test the battery. Ridiculous!
