Hyundai cars, Sonatas in particular, have been subject to numerous problems including brake line deficiencies, transmission problems and defective gear shifters. In J.D. Power's 2014 Vehicle Dependability Study, an average of 169 problems per 100 vehicles were reported by Hyundai owners.
Hyundai recalled 133,075 cars in 2014 stating affected sedans were experiencing brake fluid leaks stemming from insufficient seals between the inner brake hose and metal brake-line fittings. 880,000 Sonatas from model years 2011 to 2014 were also recalled because automatic transmission levers were not displaying the correct gear position while the vehicle was in motion. Cars were able to roll off even if the lever showed the car was in park.
