According to a document posted online by U.S. safety regulators, General Motors tested 16 cars with defective ignition switch mechanisms to show that the vehicles are safe to drive.
A General Motors report filed by the National Highway Traffic Safety Administration (NHTSA) said it removed the switch detent plunger and spring from the faulty switch to make it easier for the switch to change positions, but the switches did not malfunction in the additional tests, according to Automotive News.
“Test results showed no incidents of unintended key rotation when only an empty key ring was attached to the ignition key,” General Motors said in the May 6 report.
General Motors spokesman Jim Cain added, “We stress tested our conclusions from the initial 80 tests. We did this at our own discretion to present the strongest possible case that our advice is good.”
General Motors has gone on record saying the recalled cars are safe to drive as long as drivers use only the car key without any other items on the fob. A Texas lawsuit was filed to get GM to issue “park it” orders, but the judge ruled that the NHTSA, not the court, had more say on the matter. The NHTSA has stated it doesn’t feel this imperative is necessary.
