The 2010 Volkswagen Routan has 3 recalls, all centering on the same ignition switch defect: the key can slip out of the run position while driving, cutting engine power and disabling airbags, power steering, and power brakes mid-trip.
When the key shifts unexpectedly to the accessory or off position, the engine shuts off without the driver intentionally doing so. Losing power steering means the wheel becomes significantly harder to turn, and losing power brake assist means the pedal requires much greater foot pressure to slow the vehicle. At the same time, the airbag system loses power, leaving occupants without that protection if a collision follows the sudden engine cutoff. The combined effect, reduced steering response, reduced braking ability, and inoperative airbags, raises the risk of a crash and increases the consequences if one occurs.
