Hyundai Motor America has issued a safety recall affecting 28,439 Genesis luxury vehicles, including the full-size G90, mid-size G80, and sporty G70 models. These vehicles, manufactured in South Korea between June 2016 and September 2021, are all equipped with Hyundai’s 3.3L twin-turbocharged V6 engine.
Known internally as the G6DP, the Lambda II RS T-GDi was introduced in late 2015 with the Genesis EQ900, followed by the U.S.-spec G90 as a 2017 model.
In this iteration, the 3.3-liter engine generates 365 horsepower and 376 pound-feet (510 Nm) of torque, compared to the 420 horsepower and 383 pound-feet (520 Nm) produced by the 5.0L V8 variant.
Following the Smartstream FR G3.5T, the 3.3-liter engine is prone to oil leakage from the left-hand turbocharger oil supply line. Extended exposure to high temperatures could lead to a leak, potentially causing a serious engine compartment fire if the oil contacts the V6’s exhaust manifold.
Hyundai’s designated part number for the left-hand turbocharger oil feed pipe and hose assembly is 28240-3L100, also applicable to the Kia K900 and Stinger sedans equipped with the 3.3L twin-turbo V6.
Reports of turbocharger oil supply pipe cracking from markets outside the U.S., including South Korea, were brought to Hyundai Motor America’s attention by Hyundai Motor Company in June 2023.
Upon a preliminary review in August 2023, Hyundai Motor America observed an upward trend in repairs during colder weather. By January 2024, Hyundai Motor Company identified inadequate material used in the pipe and implemented a material change in August 2021 to address cracking issues.
Hyundai Motor America identified 81 reports from June 2020 to January 2014 related to this condition but has no reported incidents of fires or severe consequences.
The NHTSA’s safety recall report, recall number 24V-191, indicates that dealers and owners will receive notification on May 7. Service technicians are mandated to replace the left-hand turbo oil feed pipe/hose assembly with a redesigned part featuring stainless steel for improved durability in high-temperature conditions.
Currently, the G70 stands as Genesis’s most affordable offering, starting at $41,500 for the 2.5-liter turbo I4. Adding all-wheel drive costs an additional $2,100, while the V6-powered G70 begins at $49,950 with rear-wheel drive.
The G80, available in all-electric form, starts at $54,400 (excluding freight) with an internal combustion engine or $74,375 for the zero-emission variant.
The flagship G90, now exclusively powered by a twin-turbo V6 engine, starts at $89,200, while the 3.5T E-Supercharged AWD variant, incorporating an electric supercharger, retails at $99,500 in the U.S. market.
