Internal Ford documents about Explorer rollovers take a look at engineering
These days, federal safety investigators are scrutinizing Toyota, seeking the elusive causes behind hundreds of reports of unintended acceleration.
But a decade ago, the federal safety agency were facing another high-profile technical mystery: More than 100 people had died in Ford Explorers. Was it faulty Firestone tires or was the Explorer itself too prone to rollover?
The National Highway Traffic Safety Administration eventually sided with the automaker, blaming the tires and rejecting charges that the popular sport-utility vehicle was unstable.
But previously unreported internal Ford documents dredged up in lawsuits since then conflict with the finding that only tires were to blame and call into question the agency's decision not to open a full investigation into the Explorer. The Ford memos show that the company's own engineers had discovered potential dangers in two key Explorer features, its suspension and roof strength, that could make the vehicle especially lethal during a blowout.
