The ODI will evaluate both the scoping and timeliness of the decision making, as well as the adherence to reporting requirements. Obviously enough, the feds will further look into the varying defect and remedy descriptions of the safety recalls.
As mentioned earlier, nearly 6.4 million vehicles were recalled in total for potential anti-lock brake module fires. The 16 recalls are split equally between Hyundai and Kia, beginning with 20V-520, 20V-543, 21V-161, 21V-160, 21V-303, 22V-056, 22V-810, and 23V-651 for Hyundai. Over at Kia, the safety recalls in question are 16V-815, 20V-518, 20V-519, 21V-137, 21V-331, 22V-051, 22V-800, and 23V-652. The first two characters indicate the calendar year of issuance, namely 2016 for recall number 16V-815.
Said recall concerns 71,704 examples of the 2008 to 2009 model year Kia Sportage over the improper sealing of the hydraulic electronic control unit's wiring harness cover. If moisture reaches the circuit board, the subsequent electrical short circuit could lead to a fire. Back then, Kia instructed its US dealer network to replace the connector cover. In case of corrosion on the connector pins, dealers had to replace both the connector cover and control unit.
Hyundai further explained that brake fluid could leak onto the printed circuit board of the anti-lock brake controller, leading to an electric short circuit. Rather than replacing the ABS module with a better-designed assembly, the South Korean automaker will replace the ABS fuse to limit the operating current of the ABS module. Known owners have been informed about this recall on November 21.
As the ODI notes in the audit query (attached below in portable document format), these discrepancies in defect and remedy descriptions are suspicious. More suspicious still, there are different accounts for how the recall condition was corrected in production.
Given how much time is required to get to the bottom of each and every one of the 16 recalls, the Office of Defects Investigation within the NHTSA will likely provide us with an update in 2024. First half or second half of 2024, it's nigh-on impossible to tell.
