No new NHTSA electrical complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
The engine turning off unexpectedly can increase the risk of a crash. If a crash occurs under this condition, the air bag may not deploy, increasing the risk of injury.
The engine may inadvertently start and run for up to fifteen minutes. The engine may continue to start and stop until the fob battery is depleted, or until the vehicle runs out of fuel. If the vehicle is parked in an enclosed area, there is a risk of carbon monoxide build-up which may cause headaches, dizziness or, in extreme cases, unconsciousness and/or asphyxiation.
