The government plans to release the findings of its investigation into runaway Toyotas today.
The Transportation Department's report is due out this afternoon, but experts think the government may not be able to come up with definitive answers as to what caused those acceleration problems.
Toyota recalled vehicles because of sticking accelerator pedals, pedals that snagged on floormats, and other safety issues.
There have been more than 11 million recalls since Fall 2009.
In August, officials said a preliminary review did not reveal electronic flaws.
Toyota has had to pay nearly $50 million dollars in fines connected to the two major recalls.
The company could face costs of up to $10 billion dollars in potential lawsuits.
The final report is expected to be released Tuesday afternoon.
