(AP) -- WASHINGTON - Government investigators have found no new safety defects beyond problems with accelerator pedals that explain reports of sudden acceleration in Toyotas, according to preliminary findings by the Transportation Department.
Safety experts have said vehicle electronic systems could be to blame for the massive recalls but the initial review by the government has found no evidence of those problems.
Toyota has recalled about 9.5 million cars and trucks since October.
The Transportation Department says it has not found any new causes of the problems beyond two previously identified problems - floor mat entrapment and sticking accelerator pedals.
