The evidence is right there in the name: General Motors, Ford Motor Company and Bavarian Motor Werks, to rhyme off just a few.
Today’s high-tech engines still bear some resemblance to Nikolaus Otto’s four-stroke internal combustion engine of 1876. Despite almost 150 years of research, development and refinement, the principle of using a reciprocating piston to extract power from a controlled explosion endures.
Still, mistakes can happen. Some engines can run out of oil or throw a timing chain and grind themselves to smithereens. Here are seven engines in some late-model vehicles that have been known to fail catastrophically. Use at your own risk.Hyundai and sister company Kia may be winning trophies for quality, but here’s some sobering news: The South Korean automakers are recalling 1.4 million cars and sport utilities because their 2.0-L and 2.4-L four-cylinder engines can spontaneously seize, increasing the possibility of a crash. The Theta II engines were made at Hyundai’s plant in Alabama.
The U.S. National Highway Traffic Safety Administration revealed that metallic debris left behind from the manufacturing process can restrict oil flow to connecting rod bearings. The restriction can increase temperatures and cause the bearings to wear and fail, and the engines can stall and even seize abruptly. An ominous sign is a knocking sound emanating from the engine.
The recall covers some of the automakers’ most popular models, including 2013-14 Hyundai Santa Fe Sport SUVs and Sonata sedans, 2011-14 Kia Optima sedans and 2011-13 Kia Sportage and 2012-14 Sorento SUVs. And it’s not the first time. In 2015, Hyundai recalled half a million 2011 and 2012 Sonata sedans whose engines exhibited the same issue. Laudably, Hyundai and Kia will replace the engine block at no cost, if required.
