Has happened on the freeway surface streets, turning, accelerating, even when braking.there have been times when it wouldn't start and no documentation or invoices available at this time. We have to tug on ignition wires. Possible reason-ignition switch under the steering wheel section is bad. This vehicle has a console, plan on getting new ignition switch.”
