Toyota Motor Corp.'s accelerator pedal problem isn't likely to have much of an impact on its bottom line this year, but the damage to its image will undermine it in the long term, analysts said Thursday.

"The impact on Toyota's business performance will be limited," an auto analyst at a Japanese securities house said on condition of anonymity. "But Toyota's image of safe and high quality is damaged."

The world's top automaker said Thursday it will recall an additional 1.09 million vehicles in the United States to rectify potential problems with gas pedals and floor mats.
