“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.”

“The contact owns a 2012 Hyundai Genesis. The contact stated while driving at an undisclosed speed, the brake pedal was depressed and went to the floorboard, and the vehicle failed to immediately stop. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the brake booster and brake master cylinder. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 13V489000 (Service Brakes, Hydraulic) but the VIN was not included in the recall. The manufacturer was notified of the failure, and a case was opened. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was 22,000.”

“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…”

“WITH LOW BEAM HEADLIGHTS ON WHILE DRIVING, ACTIVATING THE TURN SIGNAL WILL TURN ON HIGH BEAM HEADLIGHTS OR CAUSE THE LOW BEAMS TO TURN OFF INTERMITTENTLY (ABOUT HALF OF TURN SIGNAL OPERATIONS). LIGHTLY TOUCHING OR TAPPING THE LIGHT STALK WILL HAVE THE SAME EFFECT. ON OCCASION, THE HEADLIGHTS WILL CEASE FUNCTIONING ON LOW BEAM WITH NO DRIVER ACTIVITY. THIS PROBLEM HAS BEEN OCCURRING FOR THE PAST 3 MONTHS. OTHER GENESIS OWNERS HAVE REPORTED THE SAME PROBLEM ON THE HYUNDAI GENESIS OWNERS WEBSITE. I HAVE STOPPED DRIVING THE CAR AT NIGHT.”
