On Sunday, a consumer safety advocate, who is all set to testify in the coming week in a congressional investigation of safety issues that are being faced by Toyota Motor Corp, said that the automobiles manufacturer has "skirted" a complete probe of unintended acceleration in its cars and trucks, which led to an increased risk of growing recalls.

"I suspect that we are going to see a series of recalls appear over a period of time here, certainly over the next year, and they are going to address varying issues and varying vehicles", said Sean Kane, founder of the Safety Research & Strategies Inc, a consumer safety group.

As has been revealed in a report of 180-pages that the group published on its official website on Friday, Toyota has still not been able to complete uncover the cause of unintended acceleration in Toyota and Lexus automobiles, that have led to the largest ever recall.

"We are looking at the report, but we are not prepared to comment at this time", said Toyota spokeswoman Martha Voss.
