The Los Angeles Time has reported that investigators from the San Diego County Sheriff’s Department could not rule out electronic or mechanical problems in the deadly unintended acceleration crash that killed a California Highway Patrolman and three others.

The high-speed crash of a Lexus ES 350 that killed an off-duty California Highway Patrol officer and his family Aug. 28 may have been caused by the car’s accelerator pedal becoming trapped by a rubber floor mat, but a range of other possible electronic or mechanical problems could not be ruled out, investigators for the San Diego County Sheriff’s Department have found.

The crash, which killed CHP Officer Mark Saylor, his wife, daughter and brother-in-law, has led to the recall of more than 4.2 million Toyota and Lexus vehicles to fix what federal safety regulators have called "a very dangerous problem" involving the amount of clearance between the gas pedal and the rubber floor mats.

But the inquiry leaves open a number of questions about the cause of the accident and the role floor mats have played in more than 1,000 reported acceleration events across the nation in the last eight years. The investigators’ 61-page report also raises the possibility the Saylor crash was preventable.

Toyota denied that it even had a sudden acceleration problem for more than five years. Even when Toyota acknowledge there could be a problem, it did so by making "inaccurate and misleading" statements about the safety of Toyota vehicles and received a strong public rebuke from the regulators at the National Highway Traffic Safety Administration (NHTSA).

The findings from the independent investigators at the San Diego County Sheriff’s Department further bolster the findings of independent safety experts that the Toyota electronic throttle — not floor mats — is to blame for these unintended acceleration events.

And in the key finding about the cause of the Saylor crash, the sheriff’s report hedged its conclusion, saying, "There is an indication [the incorrect floor mat] may have caused a sudden acceleration event." Investigators cited two associated factors, the lack of a key that could readily turn off the engine and brakes that "failed" because of prolonged heavy braking.

But the report further hedged it findings, saying: "Due to the catastrophic damage . . . other avenues of unintended acceleration could not be explored. Beyond the all-weather floor mat, other and/or additional factors causing a sudden acceleration event (re: electrical, mechanical or computer generated) should not be ruled out."

Independent safety expert, Sean Kane, of Safety Research & Strategies, has identified more than 2,100 Toyota sudden acceleration events. Many of these events occurred in vehicles with no floor mats at all.

Consumer Reports also confirmed that many of the sudden acceleration events occurred in vehicles with no floor mats. "There was something else, outside the cabin, that was causing the problem."

After ignoring this problem for more than five years, Toyota’s accelerator problem has been in the spotlight for several months after an August collision involving an out-of-control Lexus ES (made by Toyota) in San Diego County that killed four people, including an off-duty California Highway Patrol officer.

That collision and public outcry led Toyota to finally recall more than 4 million vehicles. While Toyota initially tried to blame the accelerator troubles on a floor mat issue, it became evident that this was not simply a floor mat problem. Independent safety experts continue to point to Toyota’s electronic throttle controls, not the floor mats, as the source of the sudden acceleration defect.

Fueling criticisms of Toyota’s electronics and electronic throttle controls, the National Highway Traffic Safety Administration (NHTSA) just announced an investigation into nearly 400,000 additional Toyota vehicles because of engine stalling related to the vehicle computer.

Why did it take Toyota more than five years to even acknowledge this problem? Why did Toyota put its head in the sand when it came to problems with its electronic throttle controls? Did Toyota think it didn’t have to play by the same rules as the rest of us? How many deaths does it take for Toyota to do the right thing?

Until Toyota finally creates a solution that actually fixes the problem, all Toyota drivers must be prepared. You can learn how to stop your vehicle if it experiences the sudden acceleration problem at this post.

    I am the owner of a 2007 Toyota Corolla, which has not been part of the recall, but I thought I needed to let someone know the electrical computer problems that I have experienced, so if anyone else has had these problems some more dots could be connected. Last summer my "check engine" light came on. I took it to the dealer. This is what the report concluded verbatim..."c/s check engine light is on. see diag sheet. The transmission operation seems different. The electronic control unit has an intermittent internal malfunction. Completed testing of the ECU. Found no codes. Could not communicate with the ECU with the tech stream. Replaced the ECU. Clear and Reset the system. Road tested." The engine computer was replaced. This was before any recall issues...

    Then, several months ago, my cars passenger side "fasten seat belt" alarm kept going on and off when there was no one sitting there. It would literally be activated every time I turned a corner or pushed on my brakes. My only remedy was to fasten the passenger seat belt at all times. I was planning on taking it back to the dealer to get it fixed , and then the issue just stopped. I don't know where I should be reporting this, so if anyone could further assist me, please contact me at
