GM has hired an outside law firm to find out what went wrong in the ignition recall case. But Adler wouldn't say whether the firm will look into other safety and process problems that occurred around the same time. "We are focused on this case," he said.
GM also said Wednesday that it will send letters to all 1.6 million owners starting March 10 telling them to use only the key in the ignition until repairs are made. Anyone with ignition problems should contact dealers. Another letter will go out in April telling people they can take their cars in for repairs.
