A month after Toyota vowed to fix vehicles that suddenly accelerated, some car owners have already started complaining that the repairs were insufficient, according to a report in the Los Angeles Times Wednesday.

So far, at least seven complaints in the last two weeks have been filed with the National Highway Traffic Safety Administration, saying the repairs to pedals and floor mats have not stopped their cars from surging unexpectedly, the paper reports.

NHTSA has not confirmed the allegations.

"There is already doubt out there that the solutions Toyota has put forward really fix the problem of unintended acceleration," Aaron Bragman, an auto industry analyst told the newspaper.
