Hyundai Sonata dangerous steering shake at 70 mph and loss of power, multiple repairs attempted on Hyundai Sonata

Some Hyundai Sonata owners report experiencing a dangerous steering shake at high speeds, particularly around 70 mph, accompanied by a loss of power steering. This shaking can manifest as vibrations and clicking sounds, raising significant safety concerns and potentially leading to a loss of steering control. The causes of this issue may include unbalanced or misaligned wheels, tire damage, bent rims, bad wheel bearings, loose lug nuts, faulty axles, worn suspension or steering components, or incorrect tire pressure. Additionally, some owners have noted that the loss of power steering during deceleration may be linked to a failed MDPS module, software issues, or a faulty steering angle sensor. It is crucial for owners to address these concerns promptly to ensure both road safety and driving comfort, and consulting a qualified mechanic or Hyundai service center is advisable for proper diagnosis and resolution.
