What 269 owners told NHTSA about the 2012 Hyundai Genesis Coupe

Brake pedal has been intermittently low/spongy and has progressively gotten worse. During these events, the brake pedal goes nearly to the floorboard, and braking power is weak but will typically function after pumping the pedal repeatedly. Stopping or slowing in an emergency situation may not be possible. There is no manual emergency brake. No trouble codes found, and no warning lamps illuminated related to the braking system. Dealer diagnosed faulty antilock braking system (ABS) hydraulic electronic control unit (HECU). This exact defect is addressed in Warranty Extension TXXP: Hydraulic Electronic Control Unit (HECU) [XXX] Hyundai rejected this under the warranty coverage because the vehicle build date is approximately 2 weeks beyond the date range in the TSB. Subsequent web searches revealed replacement parts were available for production in late XXX. The TSB's affected date range ends on XXX. This vehicle was produced on XXX and was not included in the recall notifications. It is not known if a complete stock purge was performed on the production line or if parts were continued to be installed until old stock was depleted. Other vehicles outside of the TSB stated production date range may also have this latent critical safety defect.

I am submitting this letter as a formal safety defect complaint regarding my 2012 Hyundai Genesis 5.0 sedan, which is experiencing braking system behavior that directly mirrors the defect described in Hyundai Recall Campaign 114 (NHTSA Campaign 13V489000), despite my vehicle not being included by VIN. Although excluded by VIN, the functional failure mode matches recalled vehicles, indicating the defect population may extend beyond the original VIN range. The vehicle exhibits the following symptoms: 1.Excessive and inconsistent brake pedal travel 2. Soft and spongy brake pedal feel 3. Highly variable brake biting point 4. Requirement to pump the brake pedal to obtain normal braking 5. Unpredictable brake engagement during normal driving These symptoms are intermittent and occur without warning, significantly increasing stopping distance and reducing driver confidence. The behavior is consistent with internal hydraulic or HECU malfunction, which the original recall attributes to corrosion caused by improper brake fluid formulation. I am particularly concerned because I am a disabled driver, and any reduction in braking reliability presents an elevated safety risk. Unpredictable brake response materially affects my ability to operate the vehicle safely and to respond to emergency conditions. While Hyundai has limited the recall to certain VIN ranges, Model Years Affected: 2009–2012 Hyundai Genesis sedans built April 30, 2008 – March 28, 2012. The braking behavior is functionally identical to recalled vehicles. This suggests the defect may not be limited to the originally identified production range and warrants further investigation. I respectfully request that NHTSA: 1. Review this complaint in the context of the existing recall 2. Evaluate whether the defect population should be expanded 3. Initiate further inquiry into VIN-excluded vehicles exhibiting identical symptoms 4. This issue represents a clear safety concern with potential for serious injury

Brake line on driver rear rusted and leaking above brake hose. Cannot drive vehicle safely with this leak. Would leak brake fluid each time I step on brake pedal. Problem magnified when car is on and brake booster is working. Vehicle not at dealer or mechanic yet, but link to video of driver rear brake line leaking on 1-31-2026: [XXX] Service Campaign 991 [XXX] ) was completed less than two years ago on Feb 19, 2024 (today is 1/31/2026). See note about "dealer will apply an anti-corrosion treatment to certain parts, and *replace the brake lines if necessary*" Not told about any rust, nor any parts replaced. Link to service campaign quote: [XXX] No warning lamps, messages, or symptoms of the problem. Assumed wheel liner covered brake line from salt. Vehicle is located in [XXX] and I suspect other brake lines are also rusted out. Would like manufacturer to replace all brake lines under warranty.

During normal driving conditions, the 8 speed automatic transmission will randomly hesitate to upshift from 2nd to 3rd and from 4th to 5th, causing an unpredictable loss of power. Symptoms will show up intermittently, and do not seem to be caused by certain events. This is unsafe because the unpredictability of the problem could cause power loss during moments where acceleration is needed to avoid an accident (moments which would otherwise be completely safe, i.e. merging onto a freeway, turning across incoming traffic, right turns into the direction of traffic, etc.) This problem already has a TSB issued by Hyundai. Problem has been reproduce by a technician. Component has been checked by a technician. There are no warning lights or other symptoms before failure.

Driver's side passenger door lock does not electronically function--either by key fob or by driver's control. Passenger door must be manually locked and unlocked. This defect was present from time car was purchased new but was only discovered after car was out-of-warranty since passenger door had never been used until grandchildren began using back seat. This represents an safety hazard in the event that back-seat passenger needs to exit car quickly via electronic means. We are aware that this defect is quite common among 2012 Hyundai Genesis owners. Hyundai Motors of America knows that this was a manufacturing design defect but thus far, is unwilling to support warranty repair. Warranty repair is quite costly, averaging $700-900, and this is likely the reason why HMA has elected to publicly hide and ignore the issue.

Brakes are spongy/soft - My car has been inspected by a Hyundai dealership and an ABS control module replacement has been recommended at cost of $2901. A safety recall campaign was issued in 2012 to include "certain 2009-2012MY Genesis (BH) produced from April 30, 2008 to March 28, 2012 (Recall #114). On May 9, 2022, TSB #22-BR-001H-1 was issued. My car's VIN indicates that my car was produced March 30, 2012 and the repair under the "extended warranty" has been denied because my car was produced two days later and therefore not included in the safety recall. I have reached out to Hyundai and I have a case manager assigned to me.

Vehicle shuts off at red lights or when making very low speed turns. Indicator on dash shows 'KEY' symbol and sometimes battery symbol. I then have to shift to park or neutral to push button restart vehicle. Other times I'm parked with vehicle idling and it simply shuts off. This issue puts me at risk because it shuts off while driving on public roads with other vehicles. The repair shop can't find out why this is happening and the vehicle flashes no check engine light and there are no stored codes. This began a couple months after I had a new battery installed in the vehicle and put a new battery in the key fob. Vehicle now, no longer recognizes key fob. I have to manually insert key fob into a key fob slot inside vehicle in order to crank it. This seems to be an issue with the 2012 model Genesis, as I have read on several online forums of other owners experiencing the same problem.
