Loss Of Drive Power From Fuel Pump Failure

Posted on by

Hyundai is taking action to address a fuel pump issue in certain 2021-2022 Genesis vehicles. This problem came to Hyundai’s attention in September 2022 when they received their first warranty claim related to a 2022 Genesis GV70 vehicle experiencing a stall / hesitation problem. As more warranty claims started pouring in, Hyundai launched an investigation to pinpoint the root cause of the issue.

The vehicles affected include:

  • 2021-2022 Genesis G80
  • 2022 Genesis GV70
  • 2021-2022 Genesis GV80

In June 2023, Hyundai successfully replicated the problem. Their investigation, which included a dimensional tolerance CT scan, revealed a potential problem: interference between the impeller (a key component of the fuel pump) and its housing, causing an obstruction. Hyundai collaborated with the supplier and identified a specific production lot of fuel pump assemblies that lacked sufficient impeller material. This issue potentially affected vehicles manufactured between June 2021 and December 2021. Consequently, Hyundai made the decision to initiate a recall.

The issue lies with the low-pressure fuel pump assemblies in these vehicles. Some of these assemblies may contain impellers that do not meet the required material specifications, which can lead to deformations. This deformation can result in the impeller interfering with the fuel pump housing, creating mechanical resistance that can cause the fuel pump to shut down.

A fuel pump shutdown can severely restrict the flow of fuel to the engine, potentially causing a sudden reduction or complete loss of power while driving. This poses an increased risk of accidents.

As of the latest available data up to August 22, 2023, Hyundai has received reports of 879 unique incidents related to this defect condition in the United States, spanning from July 1, 2021. Fortunately, there have been no confirmed crashes, fires, or injuries linked to this fuel pump issue.

To rectify the problem, authorized Hyundai dealers will replace the affected fuel pumps. The recall associated with this issue is identified by Hyundai as number 016G, and it has been assigned the NHTSA campaign number 23V-630. Additionally, the NHTSA has designated a specific campaign number for the fuel pump recall, which is 23E-068.

In summary, Hyundai is addressing a fuel pump problem in certain 2021-2022 Genesis vehicles to ensure the safety and reliability of these vehicles on the road. If you own one of these vehicles, it is important to receive the necessary replacement to avoid potential issues related to the fuel pump.

2023 Genesis G90 Abnormal Pretensioner Deployment

Posted on by

Hyundai Motor America (Hyundai) will be contacting the owners of certain 2023 Genesis G90 luxury sedans because of a defect affecting the seat belt pretensioners in their vehicles. The problem could result in an increased chance of injury to vehicle occupants.

In October 2022, Hyundai received information pertaining to an investigation into allegations of abnormal seat belt pretensioner deployments in vehicles associated with recalls 21V-796, 22V-069, 22V-123, 22V-218, 22V-354, and 22V-458. Recall 22V-816 was initiated as Hyundai continued to evaluate vehicles equipped with the same Samsong pretensioners that had not yet been recalled..

In January, during the continued analysis of the airbag control unit (ACU) crash pulse data recovered from a North Carolina incident, they found that the micro gas generator (MGG) separated despite having a lower pretensioner “time-to-fire”. This was the problem that was previously thought to be the contributor to over-pressurization of the pretensioner pipe. Because of this information, the North America Safety Office (NASO) decided to conduct a safety recall 012G (23V-094) of Genesis G80, GV60, GV70, and GV80 vehicles equipped with pretensioners without a vent valve. Recall 012G (23V-094) supersedes Recall 009G, obsoleting all affected population(s) of Recall 211/009G (21V-796).

In March, during the review of details surrounding Hyundai’s assessment of the open investigation into the recent recalls, Hyundai noted that the recent recalls address all U.S. vehicles equipped with the subject Samsong seat belt pretensioner excluding Genesis G90 vehicles. The G90 contains the same seat belt pretensioners but because it is installed facing outward and away from occupants, fragments entering the cabin area and injuring occupants are significantly less likely to happen. Based on this information, the NASO decided to conduct a safety recall (013G) of Genesis G90 vehicles equipped with pretensioners without a vent valve. NHTSA campaign number 23V-210.

According to the defect report, the subject vehicles are equipped with frontal/rear pyrotechnic-type seat belt pretensioners that could deploy abnormally in certain crash conditions. The problem is due to the over-pressurization of the pretensioner pipe. Depending on specific vehicle characteristics such as pretensioner load limiter specification, the airbag control unit logic, crash duration/severity, and micro-gas generator orientation, occupants could experience an increased risk of injury.

Owners of the affected vehicles will be notified with instructions to bring their vehicles to a Hyundai dealer to have the seat belt pretensioner’s micro gas generator and delivery pipe secured with a cap to prevent potential abnormal deployment.
