2012 HYUNDAI GENESIS — Complaint #1616120
Open-data reference.
NHTSA Complaint about SERVICE BRAKES, HYDRAULIC:POWER ASSIST:ELECTRIC:CONTROL MODULE filed October 28, 2019
NHTSA complaint #1616120 (ODI reference 11271565) concerns a 2012 HYUNDAI GENESIS and was filed on October 28, 2019. The owner reports the failure occurred on October 23, 2019. The vehicle had 79,000 miles on the odometer at the time of the incident. The report was geocoded to Minnesota based on the filer's self-reported location. The affected component is categorized as service brakes, hydraulic:power assist:electric:control module, 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 GENESIS cohort independently describe similar service brakes, hydraulic:power assist:electric:control module 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 2012 HYUNDAI GENESIS shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
ON OCTOBER 23RD, 2019, THE BRAKES ON MY 2012 HYUNDAI GENESIS R-SPEC SEDAN SUDDENLY FAILED WITH THE BRAKE PEDAL GOING ALL THE WAY TO THE FLOOR BEFORE THE VEHICLE EVENTUALLY STOPPED LUCKILY AVOIDING AN ACCIDENT. I WAS DRIVING ON THE HIGHWAY. THE VEHICLE HAS 79K MILES. I THEN TOOK THE CAR TO THE HYUNDAI DEALER IN ST. LOUIS PARK, MN AND THEY DETERMINED THAT THE BRAKE MASTER CYLINDER WAS FAULTY AND REPLACED. THE DIAGNOSIS AND REPAIR DID NOT FIX THE ISSUE AS THE BRAKE PEDAL WAS STILL SPONGY AND GOING TO THE FLOOR INTERMITTENTLY. I WILL BE TAKING THE CAR BACK TO THE DEALER TO HAVE THEM FIX IT CORRECTLY. WHILE RESEARCHING THE ISSUE, I HAVE FOUND THAT MULTIPLE OTHER OWNERS OF THE SAME CAR HAVE EXPERIENCED THIS ISSUE AND THE DEALER HAD TO REPLACE THE ABS HYDRAULIC ELECTRONIC CONTROL UNIT (HECU) AS IT CONTAINED CORROSION WITHIN THE UNIT DUE TO BAD DESIGN WHICH CAUSES HYDRAULIC BRAKING FAILURE TO OCCUR AT ANY TIME. THIS CAMPAIGN/RECALL BELOW OUTLINES THE ISSUE WHICH I AM GOING TO PRESENT
