A San Diego County sheriff's report says a customer complained of gas-pedal problems with a dealer's loaner Lexus three days before the same car accelerated out of control and killed a California Highway Patrol officer and three family members.

The report obtained Friday by the San Diego Union-Tribune says the man told a receptionist at the El Cajon dealership that the gas pedal on the Lexus was sticking, the same problem that led to the deadly crash three days later on Aug. 28.

The man told investigators he was worried and emphasized the problem.

The crash killed 45-year-old Officer Mark Saylor, his wife, daughter and brother-in-law and led to a massive recall of several Lexus and Toyota models.
