NHTSA Complaint #11458910 — 2016 HYUNDAI SONATA

Hyundai Motor America is doing fraud with its customer’s and putting their lives at danger. They made engines with manufacturing defect. They sent a brochure to their customers to get the software updated for knocking sensors and then placed a lifetime warranty for the issues caused by it including any repair costs. They said the software will detect the knocking noise and will turn on Warning lights (Engine Light) as well as place the vehicle into reduced power, engine protection mode. Their brochure said they have defective engines in 2011-2019 Sonatas, 2013-2018 Santa FE Sports, 2019 Senta Fes, and 2014,2015, 2018 and 2019 Tucsons.I own a 2016 Hyundai Sonata. I did software update and then I started having engine knocking at around 76,000 miles. Sometimes, car automatically loses power on highways/freeways and sometimes it starts to accelerate on its own at very high RPM’s. I contacted Hyundai dealership in Spring, TX (North Freeway Hyundai), which told me that Hyundai doesn’t cover it anymore until unless its complete engine failure. This is not what their Warranty document (Brochure) said. They are denying to take care of the issue which was caused by manufacturing defect and their software update. Their brochure said they will take care of it including any engine repair costs. Their dealership told me that this is just the “Beginning of the engine falling apart”, they can start with putting a new cover on the faulty engine part rather than replacing it, which will cost me $640.50+tax to take the engine light disappear for few days. If they have to fix it permanently, it is going to cost me “Thousands of Dollars” into parts and labor charges. Private mechanic said Hyundai Engines are "Can of Worms" and wont even touch it. As per Hyundai case managers instructions, I ended up spending $435.50 out of pocket without any work done on my vehicle. As per their Brochure, they are making defected engines from 2011. Thousands of people driving those dangerous vehicles.
