Hyundai Motor America is recalling 2022-2023 Genesis GV70, GV80, G80, and G90 vehicles because the fuel pump may fail, which can result in a loss of drive power. According to documents made public today by the National Highway Traffic Safety Administration, this is an expansion of a previous recall for the same safety defect. More than 31,000 vehicles are affected assembled at Hyundai Motor Manufacturing Alabama or imported for sale into the United States.
“The low-pressure fuel pump assemblies in the vehicles may contain impellers that can deform under certain environmental conditions, such as high ambient temperature. Deformation of the impeller could cause the impeller to interfere with the fuel pump housing, resulting in a mechanical resistance that could lead to a shutdown of the fuel pump,” the NHTSA filing said.
A shutdown of the fuel pump could restrict fuel flow to the engine, resulting in a sudden reduction or loss of motive power, increasing the risk of a crash. The fuel pump impeller might not meet material durability specifications under certain environmental conditions, such as high ambient temperature, due to a deviation in the production process of the Tier 2 supplier located in South Korea.
How Hyundai Got Here
- On September 11, 2023, HMNA launched recall 016G (23V-630), a safety recall of certain U.S. market Genesis GV70, G8V80, and G80 vehicles to address a known condition involving swelling of the impellers used in the vehicles’ low-pressure fuel pumps.
- On 27 September 27 2023, HMNA’s North American Sales Office initiated a part recovery request for vehicles outside the affected production scope of 23V-630 for investigation based on continued monitoring of fuel pump assembly-related warranty claims.
- By 18 October 2023, seventeen (17) fuel pumps were recovered and shipped to HMC for analysis. Around this time, HMNA noted an increase in claims received for vehicles produced from July through August 2022. HMNA continued recovering parts and continuing its investigation accordingly.
- On 1 December 2023, HMC and the supplier performed a joint inspection of several production lots containing fully assembled fuel pumps. A suspect lot potentially containing defective pumps was identified and recovered for disassembly and analysis. During subsequent analysis of recovered parts, HMC discovered evidence of swelling on 12 out of 21 fuel pumps recovered.
- On 6 December 2023, North America sales provided an update of Recall 23V-630 launch status, including TSB release information to NHTSA’s Office of Defects Investigation (“ODI”) during its monthly review of top safety-related investigations.
- January – April 2024 Hyundai continued analyzing recovered parts through January 2024. Thirteen (13) additional fuel pumps were recovered and sent to HMC for analysis. During this time, NASO noted that several pumps were produced on dates outside of the suspect production range identified in the prior decision to conduct Recall 23V-630.
- On 15 February 2024, HMC informed N North America sales that additional testing performed on parts from the Middle East indicated that fuel pumps used in certain model year Genesis G90 vehicles may also be affected by the defect condition. NASO conducted a review of U.S. and Canadian market field information and escalated the case directly to the Technical Review Committee (“TRC”) for further consideration. North America sales continued frequent communication with HMC to fully understand the raw material lots used throughout the subject vehicles production range to determine the scope of vehicles potentially affected by the subject condition.
- On 28 February 2024, North America sales reviewed its initial findings with ODI during its bi-monthly review of top safety-related investigations.
- On 12 April 12, 2024, North America sales convened its North America Safety Decision Authority (“NASDA”) to review the TRC’s analysis of HMC’s findings and decided to file a new recall to address all vehicles potentially containing suspect low-pressure fuel pumps from the additional production lots identified by HMC and the supplier.
- As of the date of this filing, HMNA has confirmed 463 unique incidents involving the subject vehicles received from 27 July 2022, through 13 February 2024. There are no crashes, injuries, fatalities, or fires related to the recall in the U.S. market.
Genesis dealers will inspect and replace the fuel pump assembly, free of charge as required by US safety regulations. Owner notification letters are expected to be mailed 18 June 2024. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai’s number for this recall is 022G. This recall is an expansion of recall number 23V-630.
