Toyota targeted by environmentalists at car show.

LOS ANGELES -- Toyota Motor Corp. is usually the darling of the Los Angeles Auto Show, but testy relations with environmentalists and questions about quality are making the show a headache for the automaker this year. It doesn't help that Toyota chose to introduce a full-size sport utility vehicle at the show, and the redesigned Sequoia doesn't have a hybrid option like full-size SUVs from General Motors Corp. and Chrysler LLC that are debuting across the show floor. The Los Angeles show opens to the public Friday after two days of media previews.
