2012 Hyundai Genesis service brakes problems

“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…”

“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…”

“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.”

“Sep 22, 2023 Manufacturer Recall Number251 NHTSA Recall Number23V651000 Recall Status: Recall Incomplete, remedy not yet available June, 2024 It has been 10 months since an alert from Hyundai to park this vehicle outside due to chance of fire. I need this car repaired or repurchased by Hyundai. 10 Moinths is far too long for a repair.”

“Re: [XXX] It has been 6 months since a recall notice was sent indicating: FIRE RISK WHEN PARKED As of 3/9/2024, the recall is still marked: REMEDY NOT YET AVAILABLE This is unacceptable. What are my options to get this resolved immediately? [XXX] [XXX]”
