This was an unintended acceleration with non functional braking of a Lexus GS 350. This occured on December 18 around 8:00 AM. The driver noticed an orange triangular light in the dash while travelling slowly through a neighborhood less than a mile from the incident. While approaching a lighted intersection, the car suddenly accelerated when the brake pedal was depressed. The brake pedal was stiff and did not work. The driver tried to avoid another vehicle by veering right. The car hit a curb, travelled over a small hill and ended up in a parking lot after the ensuing damage disabled the car. The driver was able to escape from the drivers door before a fire erupted on the drivers side of the engine bay. The driver's safety and any other cars or persons in the vicinity were obviously put at grave risk.
