According to an Office of Defect Investigation (ODI) filing with NHTSA, the 3.3-liter V6 diesel used in the 2017 Santa Fe has a potential engine knock.
The National Highway Traffic Safety Administration’s (NHTSA) Office of Defect Investigation (ODI) is currently reviewing a petition filed on February 2, 2024, requesting an emergency investigation into the alleged defect affecting Hyundai’s Korean-brand 3.3-liter vehicles. GDI Lambda- II engine in the USA. NHTSA is a United States federal government agency, part of the Department of Transportation, that focuses on transportation safety in the United States.
The petition, filed by Jasmine Jewell, owner of a 2017 Hyundai Santa Fe, expresses concern about engine malfunctions and safety risks associated with the 3.3-liter GDI Lambda-II engine. Jewell’s Santa Fe developed engine failure at 98,834 km, prompting him to find a replacement engine at a cost of $19,997 which is approx. ₹16,60,075, excluding labor charges, after finding local Hyundai dealers overwhelmed by such issues.
Jewell’s petition claims that the 3.3-liter GDI Lambda-II engine is susceptible to engine knocking, causing the engine to seize without warning. Despite previous recalls for 2017 Santa Fe models with the same engine, Jewell says major concerns about engine reliability remain.
Additionally, Jewell notes that multiple class action lawsuits have been filed against Hyundai and Kia, alleging defects in GDI engines that pose a risk of stalling or catching fire. The Kia Sorento is also being investigated for the same engine issue. In Canada, a class action has been filed for various Hyundai GDI engines, including the 3.3-liter Lambda-II, while a separate lawsuit in Australia claims Hyundai has been aware of engine issues since at least 2015.
In his petition, Jewell is formally asking the NHTSA to begin a rulemaking process to evaluate and potentially modify existing vehicle safety standards governing the Hyundai 3.3L V6 Lambda II engine. He says that such a commitment is necessary to ensure these vehicles comply with safety standards that fully address identified defects and prevent further harm to consumers.
As of now, the request is still being investigated by the ODI, and no decision has been made regarding further action or possible reinstatement. NHTSA will continue to monitor the situation and provide updates as the application progresses.
While the Santa Fe was also sold in India, the Indian model had a 2.2 liter diesel engine, which is also used in cars like the Kia Carnival.
