In Hyundai and Kia discovered a dangerous, but incomprehensible malfunctionJanuary 24, 2019
The American Institute for Highway Safety Insurance (IIHS) was unable to identify the cause of the mass spontaneous combustion of Korean cars.
Hyundai and Kia cars equipped with the Theta II family of engines have a higher risk of fire. These conclusions were made by experts of the US Insurance Institute for Highway Safety (IIHS), who studied the statistics of spontaneous fires Hyundai and Kia.
Recall that Hyundai and Kia were at the center of the scandal soon after the Center for the Fight for Car Safety (CAS) called on automakers to withdraw more than 2 million Kia Sorento, Kia Optima, Hyundai Santa Fe and Hyundai Sonata 2011-2014. The reason was the owners’ complaints about the smoke and the smell of burning, as well as the cases of spontaneous combustion of vehicles.
During the investigation into the causes of fires, IIHS experts studied detailed statistics of such incidents and concluded that the risk of a fire without a collision was much higher for the 2011-2013 Kia Optima and Hyundai Sonata models than the control cars (the make and model of the car was not disclosed ). In addition, the high rates of “fire threat” were received by the Kia Sorento 2011-2015, the Hyundai Santa Fe 2012 and the Hyundai Santa Fe Sport 2013-2014 release.
At the same time, the highest fire risk indicators were assigned to models equipped with a two-liter turbo engine. Thus, for 10,000 insured cars, 4.2 such incidents occurred. For comparison, in the control model this indicator was 1.7. Hyundai and Kia, equipped with 2.4-liter engines, also have a high risk of fire – 2.7 cases of fire per 10,000 cars. In addition, the researchers noted that the risk of fire “increases dramatically” with the aging of cars.
Experts add: in spite of the fact that much attention was paid to the Theta II family of engines installed on these cars, some fires may have other causes. Recall that about 1.7 million cars Hyundai and Kia were withdrawn, starting in 2017, due to engine problems. In particular, the motors could stall due to a defect in the crankshaft and bearings.
