Ford Motor Co. finds itself in legal hot water again over allegations that the roofs of some Ford Explorer SUVs are not safe.
Safe Analysis and Forensic Engineering (SAFE Research), a California car safety advocacy firm, has asked the National Highway Traffic Safety Administration to investigate the issue, according to The Detroit News.
The firm says internal Ford documents show that a number of 1999-2001 Explorers do not meet the government's roof strength standard.
Ford disputes the allegation, saying the firm misinterpreted its tests, which it says were made on an experimental vehicle.
NHTSA expects to respond within four months.
Ford already is facing numerous lawsuits over the strength of the roofs on some Explorers.
