Toyota Motor Corp will recall 1.1 million cars globally for defects, including 752,000 Corolla and Corolla Matrix vehicles in the United States to fix airbags that could be deployed inadvertently, the automaker said on Wednesday. The airbag problems have caused minor injuries such as abrasions in 18 cases that have been reported, Toyota spokesman Naoto Fuse said. Two accidents have been reported by customers outside Japan, although Toyota has not been able to confirm them, he said. An IC chip in the airbag control unit can malfunction when it receives electrical interference from other cars, causing the airbags to deploy when it is not necessary, Fuse said. Toyota will add an electrical signal filter to the airbag control module to the recalled vehicles -- repairs expected to take an hour to hour-and-a-half, he said. The spokesman declined to disclose the costs involved. Separately, Toyota will also recall 385,000 Lexus IS and its series, including 270,000 Lexus IS vehicles in the United States over wiper problems, Fuse said. The wiper arm nut of the front wiper in these vehicles may not be tight enough and the wiper may not work under certain weather occasions, including in snow. Toyota will exchange the nut in repairs that will take about 30 minutes, Fuse said.
