2011 Hyundai Genesis

On October 28, 2013, Hyundai Motor Company (Hyundai) submitted a Defect Information Report (DIR) to NHTSA describing a safety defect in the braking system of approximately 43,500 model year (MY) 2009 through 2012 Hyundai Genesis sedans (NHTSA Recall No. 13V-489).The Hyundai report indicates that the recalled vehicles may contain brake fluid that does not sufficiently inhibit corrosion on the zinc plating of control valve armatures in the Hydraulic Electronic Control Unit (HECU) module. The DIR indicated that, over time, the build-up of corrosion products may affect operation of HECU control valves, resulting in a low/soft brake pedal with reduced brake effectiveness, which may increase the risk of a crash.In October 2011, the HECU supplier notified Hyundai that the brake fluid used in production plants was causing corrosion of valve armatures in the control module.The supplier changed the coating of the valve armatures in late March 2012 to correct the problem in production vehicles.Hyundai's recall includes Genesis vehicles produced prior to the implementation of the HECU change.In March 2013, Hyundai initiated a Service Campaign (TL6) to replace brake fluid in the subject vehicles with brake fluid with better corrosion resistance properties.According to Hyundai's DIR letter, after PE13-033 was opened, the company noted that some of the vehicles serviced in the TL6 campaign subsequently required HECU replacement.This was an indication that internal corrosion had progressed enough to affect valve operation and brake performance, prompting Hyundai to conduct a safety recall.Hyundai's repair procedures for 13V-489 require brake system flushing and replacement in all recalled vehicles with a new fluid containing the necessary corrosion inhibitor.In addition, for vehicles produced prior to June 1, 2010, dealers will perform an inspection procedure to verify that the HECU is functioning properly and replace units that do not meet the test requirements.Hyundai indicated that, based on analysis of claim data, only vehicles produced prior to June 1, 2010 have been in service long enough to require the additional inspection/replacement of the HECU. Analysis of failure data reported to NHTSA and provided by Hyundai in response to ODI's information request letter for PE13-033 identified 756 complaints and 1,683 warranty claims for 30,114 subject vehicles produced prior to June 1, 2010, resulting in a complaint rate of 25.1 incidents per thousand vehicles (IPTV) and a claim rate of 5.6 percent.The MY 2009 vehicles, with the longest exposure times, experienced the highest complaint (33.5 IPTV) and warranty (7.0 percent) rates.For the 45,639 subject vehicles produced after June 1, 2010, ODI identified 13 complaints and 34 warranty claims, resulting in a complaint rate of 0.3 IPTV and a warranty claim rate of 0.1 percent, indicating that the brake fluid corrosion concern had not progressed far enough to result in significant rates of brake system performance symptoms in those vehicles.This investigation is closed.ODI will continue to monitor complaints to evaluate the effectiveness of Hyundai's recall.The VOQs noted in the Failure Report are: 10569231, 10560898, 10560495, 10559360, 10558279, 10558264, 10556964, 10556631, 10556577, 10556322, 10554988, 10554802, 10554122, 10552958, 10551817, 10551157, 10551110, 10551092, 10550791, 10550773, 10550431, 10549750, 10549634, 10549629, 10549567, 10549402, 10549376, 10549270, 10549228, 10549186, 10549021, 10548903, 10548823, 10548791, 10548737, 10548722, 10548716, 10548705, 10546565, 10544803, 10543663, 10542962, 10541959, 10541741, 10538208, 10537934, 10536652, 105354

Noticed after driving my Hyundai genesis and once running for roughly 15-20 mins once the engine has warmed up I noticed a bounce feeling coming from the front end(I thought)and then noticed my speed dropped and when pressure was apply to the gas pedal it wouldn’t go, as the car slowed down by itself until it came to a complete stop I cutt the car off and began walking around to where I smelled something burning and then seen smoke coming from my front driver wheel to discover my brake had locked up for no reason. I left the car to cool down and returned to get it and luckily it was unlocked and was successful to drive it home(4min drive), a couple days later I had to take my son to school to where it did the exact same thing again, days later I had all braking replaced which failed to solve the issue. This has been happening for over 4 months now and has always been my daily driver and has always been upkept and never had any issues with my car until now. I’m a single parent with two children whom I have to take to school daily and pickup and this issue has already cost me a lot however I was made aware of this issue by a professional mechanic whom said my car has a current recall for this exact issue I’m having but my vin doesn’t show it even thought everything lines up!

The HECU has been malfunctioning in my car for over a year now. It is an open recall for my make, model and year of car. I took it to Bob Rohrman Indy Hyundai and they diagnosed the failed part. This part affects my ABS. There are currently two warning lights on one for the ECS which is the traction control stabilizer and the ABS light is on. Meaning the use of the breaking system is limited and not working properly. I have asked the corporate Hyundai to uphold the recall warranty but I was advised they would not cover this because my vehicle has a rebuilt title. I drive my vehicle on a daily basis and I’m terrified of my brakes going out. The corrosion from the fluid is what causes the HECU to malfunction and it is so scary to think about. This problem was diagnosed and first reported to my his dealership on 6/23/2022.

The window regulators are built with a hard plastic that essentially melts in Florida heat and then your windows just drop. Each window in my car has dropped and will not go back up without paying Hyundai a lot of money to repair the window. For instance, in December 2022 I paid Hyundai $660 to repair the right rear window and in August 2022 I paid Hyundai $651 to repair the left rear window regulator (second repair). Now the front driver side window has to be repaired for the second or third time. The parts were ordered and just the parts will cost $900 and I still will have to pay the labor expenses for inferior made materials. The driver side window was replaced and a new regulator was installed by Napleton Hyundai in West Palm Beach. I do not have the paperwork for the repairs made by Napleton. Then Coastal Hyundai in Melbourne, Florida worked on the rest of the windows including putting in a new regulator in the driver side and will install a new motor. These windows are neither reliable nor safe and should not have been constructed with plastic. They just fall and will not go back up. The window parts should have been recalled and replaced. I attached a copy of the invoices that I have paid already and could locate. Also, I want to report that when I contacted Hyundai to issue a complaint about the right rear window in December 2022 it took 30 days for the customer service representative to respond to me. He apparently, would document that he planned to call me in the computer and never followed through. I called and asked to talk to his Supervisor and was told that I would have to talk with him. Not having a Supervisor to talk with was also a problem because he knew that I could only talk to him so he took his time. I don't know if anything will be done but I wanted to document my concerns.

In certain areas, a vehicle’s underbody may exhibit corrosion due to road-salt usage. As a preventative measure, a cavity wax coating is applied to the internal surfaces of underbody components and an undercoating spray is applied to exterior surfaces of specified underbody components. The service campaign describes the procedure to perform this preventative service on certain 2009-2014MY Genesis Sedan (BH), 2011-2016MY Equus (VI), and 2010-2016MY Genesis Coupe (BK) vehicles.

Certain Equus (VI), Genesis Coupe (BK), and Genesis Sedan (BH) vehicles may exhibit underbody corrosion due to road salt usage. As a preventative measure, this bulletin provides the procedure to apply a cavity wax coating to internal surfaces of underbody components, and an undercoating spray to exterior surfaces of specified underbody components.

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly.

Certain vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin provides the inspection and repair procedures for vehicles exhibiting this condition. All internal combustion engines consume engine oil as part of normal engine operation. Oil consumption rates may vary based on mileage, operating conditions, driving habits, and maintenance history. Hyundai recommends following the prescribed maintenance schedule and periodically checking the engine oil level using the dipstick to maintain proper engine oil level.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.
