Sonata

  • 11,000 miles
This incident occurred with a 2011 Hyundai Sonata limited: 6 months of perfect operation and approx. 11000 miles. Violent shaking of steering wheel and steering column after acceleration onto an on ramp. Immediate and entire failure of steering with violent and extremely loud shaking and vibrating of steering wheel. Shaking continued even after ignition shut off. Occurred for 20+ minutes. Disabled only by disconnecting battery. Blisters on hand from hanging on to steering wheel. Nothing could be done to steer, operate, or control vehicle. This incident occurred without warning and within seconds. Towed to dealership. Kept for 3 days. Could not replicate. Steering column recall performed with steering software update, ESC reflashed, reprogrammed eps. Hyundai was excellent in their response - both dealership and Hyundai usa. Hyundai usa engineers and tech's were involved with resolving the problem. This was a frightening and dangerous incident and possibly life threatening. Whether repair attempt will resolve only time will tell.
