2011 Hyundai Sonata Owner Comments

problem #1

Sonata SE 2.0L I4

  • Automatic transmission
  • 61,000 miles

Amongst other issues that started at the 61k mile mark, the AC also started acting up. Only blows cold while vehicle is moving forward. I contacted dealer and was denied coverage by Hyundai USA. Contacted Hyundai USA and was denied again. The worst vehicle I've ever owned.
