As we were driving on a smooth asphalt dry road the abs light and the brake failure light came on along with an anunciator sound warning. We immediately pulled over and brought the truck to a stop. We tested the brakes by pushing on the pedal and we still had good brakes. We continued carefully on home and inspected the brake fluid which was ok. After turning off and then turning on the key and starting the engine, the abs warning light came back on but the brake failure light was not illuminated. Yesterday, (11/10/2013) our grandson brought his computer analyzer out, hooked it up and determined the failure was in the left front wheel sensor. He did not clear the history from the vehicle's computer. It seems to me this is a problem as this truck has such low mileage. I bought this truck from a Hyundai dealer about the first of August 2013 and have put less than 2,000 miles on it. They told me it had never been wrecked nor does it show any evidence of having been repaired. The previous owner apparently had it serviced on a regular and proper basis and has this all recorded in the back of the book that came with the truck. I am the second owner.
