Probe finds jump in runaway Toyota complaints-paper

* L.A. Times reports 1,000 sudden acceleration complaints

* Newspaper probe links crashes to 19 deaths, up from five

LOS ANGELES, Nov 8 (Reuters) - Over 1,000 Toyota and Lexus owners have reported sudden, spontaneous acceleration of their vehicles since 2001, including crashes blamed for 19 deaths, far more than earlier disclosed, the Los Angeles Times reported on Sunday.

The National Highway Traffic Safety Administration previously has said it had received reports of 100 such incidents, including 17 crashes and five fatalities.

Toyota Motor Corp (7203.T: Quote, Profile, Research) announced in September that it would recall some 3.8 million vehicles in the United States because of the risk of improper-fitting floormats jamming accelerator pedals in several models.

The recall includes the hot-selling Prius hybrid and would be the largest ever for Toyota, which has built a reputation for safety and quality that had helped it surpass General Motors Co GM.UL as the world's leading automaker last year.

But the Times said it had uncovered a problem much bigger in scope from its own examination of thousands of federal defect investigation records, NHTSA complaints filed by car owners, lawsuits against Toyota and reports by independent safety experts and local police agencies.

Owner complaints of runaway Toyota and Lexus vehicles helped trigger at least eight investigations of the problem by NHTSA in the last seven years, but the agency closed six of those cases without finding a defect, the Times reported.

According to the newspaper, federal officials eliminated broad categories of sudden-acceleration complaints, including cases in which drivers said they were unable to stop runaway cars using their brakes; incidents of unintended acceleration lasting more than a few seconds; and reports in which owners did not identify the possible causes of the problem.
