NEW YORK — Toyota dealers across America were swamped with calls Wednesday from concerned drivers but had few answers a day after the company announced it would stop selling and building eight models because of faulty gas pedals.

Toyota insisted the problem — sudden, uncontrolled acceleration — was "rare and infrequent" and said dealers should deal with customers "on a case-by-case basis." But drivers of Toyotas and those who share the road with them were left with uncertainty.

In an unprecedented move, the company said late Tuesday it would halt sales for the eight models — which make up more than half of Toyota's U.S. sales volume — to fix the gas pedals. Last week, Toyota issued a recall for the same eight models, affecting 2.3 million vehicles.
