2012 HYUNDAI GENESIS — Complaint #1597158
Open-data reference.
NHTSA Complaint about SERVICE BRAKES, HYDRAULIC:POWER ASSIST:ELECTRIC:CONTROL MODULE filed August 23, 2019
NHTSA complaint #1597158 (ODI reference 11246144) concerns a 2012 HYUNDAI GENESIS and was filed on August 23, 2019. The owner reports the failure occurred on August 23, 2019. The vehicle had 73,000 miles on the odometer at the time of the incident. The report was geocoded to Ohio 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
WHEN THE BRAKE PEDAL WAS DEPRESSED TODAY 08/23/19, IT TRAVELED TO THE FLOORBOARD, BARELY ESCAPING REAR ENDS OF SEVERAL VEHICLES ON THE HIGHWAY AND CITY STREETS. THERE WAS NO WARNING INDICATOR ILLUMINATED. THERE IS NO EVIDENCE OF A BRAKE FLUID LEAK. THERE IS THE APPROPRIATE AMOUNT OF BRAKE FLUID IN THE RESERVOIR. HAVING ENTERED MY VIN # INTO THIS SITE HAS PROVIDED NO RECALLS. ALTHOUGH READING EVERYTHING ABOUT NO.114, THAT I HAVE SOUNDS LIKE IT SHOULD BE AND IT SHOULD BE CORRECTED. SOME PEOPLE, WHO HAVE ALSO HAD THIS PROBLEM, SAID THAT THE BRAKE FLUID USED WAS CAUSING FAILURE IN THE MASTER BRAKE CYLINDER VALVES. THIS IS OBVIOUSLY A MANUFACTURER ERROR, AND HYUNDAI SHOULD BE HELD RESPONSIBLE. I HAVE UNFORTUNATELY HAD TO LEAVE MY CAR DUE TO THIS SAFETY HAZARD OVER HOUR AND A HALF FROM HOME. THIS NEEDS TO BE ADDRESSED/FIXED QUICKLY.
