2004 HYUNDAI SONATA — Complaint #1888495
Open-data reference.
NHTSA Complaint about SUSPENSION filed April 18, 2023
NHTSA complaint #1888495 (ODI reference 11517597) concerns a 2004 HYUNDAI SONATA and was filed on April 18, 2023. The owner reports the failure occurred on December 12, 2022. The report was geocoded to VI based on the filer's self-reported location. The affected component is categorized as suspension, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same HYUNDAI SONATA cohort independently describe similar suspension failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2004 HYUNDAI SONATA shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
NHTSA Campaign 09V124000 (Hyundai Recall #089) - excessive corrosion, thinning of the metal and perforation of the front sub-frame steel, due to road salt, resulting in separation of the forward mounting of the lower control arm increasing the risk of a crash. The recall was issued in 2009 for 1999-2004 Hyundai Sonatas. The present owner purchased the vehicle in 2014 with no knowledge of previous recall. The excessive corrosion and perforation of the sub-frame was brought to the owner's attention in December 2022 during a routine oil change by a Meineke shop and reported as unsafe to drive. The vehicle was towed to Route 1 Hyundai in Monmouth Junction, New Jersey, for inspection and repair estimate on December 30, 2022 and an online complaint filed with Hyundai Motor America for the recall (Case #[XXX]). Following numerous email communications to Hyundai Consumer Affairs, it was confirmed by a National Consumer Affairs representative that the vehicle was covered in Hyundai Recall
