The differential mounting bolt on the passenger side (the only one on that side) backed out and broke causing that side of the differential to smack the bottom of the car and then sag on the passenger side after letting off the throttle. Once it dropped it made the car come to a compete stop fast. Luckily there was no accident. This exact issue has already been fixed previously under recall, due to this the dealership nor manufacturer is wanting to fix it under the recall again.

Service brakes, hydraulic: antilock/traction control/electronic limited slip: control unit/module
- What is wrong
- Hyundai Motor America (Hyundai) is recalling certain 2011-2015 Elantra, Genesis Coupe, Sonata Hybrid, 2012-2015 Accent, Azera, Veloster, 2013-2015 Elantra Coupe, Santa Fe, 2014-2015 Equus, 2010-2012 Veracruz, 2010-2013 Tucson, 2015 Tucson Fuel Cell, and 2013 Santa Fe Sport vehicles. The Anti-Lock Brake System (ABS) module may leak brake fluid internally and cause an electrical short, which can result in an engine compartment fire while parked or driving.
- Risk
- An engine compartment fire while parked or driving can increase the risk of injury.
- Remedy
- Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will replace the ABS fuse, free of charge.

Recall number 23V651000 · Recall details
Air bags: sensor: occupant classification
- What is wrong
- Hyundai Motor America (Hyundai) is recalling certain model year 2010-2016 Genesis Coupe vehicles manufactured December 12, 2008, to June 11, 2016. The electrical harness connector for the front passenger seat Occupant Classification System (OCS) may dislodge when the seat is moved.
- Risk
- In the event of a crash necessitating deployment of the passenger frontal air bag, the disconnected OCS would, by default, cause the first stage, and only the first stage, of the air bag to deploy, whether there is a child seat in the front seat and the bag should not deploy or if the crash is severe and both stages should deploy. Either scenario increases the risk of injury to the front seat occupant.
- Remedy
- Hyundai will notify owners, and dealers will secure the OCS connector to prevent it from disconnecting, free of charge. Parts are not currently available and a second letter will be sent to owners when parts are available. Owners may contact Hyundai customer service at 1‑855‑371‑9460. Hyundai's number for this recall is 151.
Recall number 16V722000 · Recall details
Power train: driveline: differential unit
- What is wrong
- Hyundai Motor America (Hyundai) is recalling certain model year 2013-2015 Genesis Coupe vehicles manufactured December 28, 2011, to April 6, 2015, equipped with manual transmissions.

- Remedy
- Hyundai will notify owners, and dealers will verify the proper assembly of the differential, free of charge. The recall began on December 30, 2015. Owners may contact Hyundai's customer service at 1‑855‑671‑3059. Hyundai's number for this recall is 135.

The contact owns a 2015 Hyundai Genesis Coupe. The contact stated while driving 10–20 MPH, the vehicle went into LIMP Mode in the first twenty minutes of driving. The vehicle speed was reduced. The check engine warning light was illuminated. The vehicle was taken to the local dealer, but the dealer was unable to determine the cause of the failure. The dealer cleared the DTC codes. The vehicle was not diagnosed or repaired. While driving, the check engine light warning illuminated. The vehicle was taken to another local dealer, Happy Hyundai (9121S Cicero Ave. Oak Lawn, IL 660453), where it was diagnosed that the accelerator position sensor needed to be replaced. The throttle body needed to be cleaned and replaced. The vehicle was not repaired. The manufacturer was contacted. The approximate failure mileage was 34,000.
There is a code that comes on my car, makes the engine light come on then it goes out on its own . And every year it’s back on same code. Has been happening for years . I took it to the dealership 2xs for the same reason each time they said nothing was wrong cleared the code and the engine light went out. This year being the 9th year having the vehicle the engine light kept coming back on every day after it was cleared and nothing found. So the Happy Hyundai dealership ship said leave the car overnight and see if the engine light is back on and if so he can see then what the issue is because it won’t be historical. I paid $212 for diagnostic, and then a few days he said leave overnight. He discovered that the throttle body had an issue and suggested cleaning. But the car goes in limp mode and I couldn’t accelerate but 20-25 mph. The first 20 mins of driving every day. Then it takes off. He determined that an accelerator pedal position sensor was bad. And I went years without any one diagnosing this. My car only has 34550miles approximately. And it’s almost 9 years old. 34k miles a sensor shouldn’t be bad that soon. The codes were P0651/ and P2106. And now in 2024, someone finally figured it out. But now it’s been almost 9 years and I’m paying $900 or 1k for replacement when it was clearly something wrong years ago . Undiagnosed.
While driving I noticed an engine noise/rattle about 3000RPM. The engine seemed to run fine but was making this abnormal noise. At 73,083 miles I towed the car to the Hyundai dealer. They found an anomaly in cylinder #5 and recommended engine replacement but refused warranty powertrain coverage because I am not the original owner. They also refused goodwill coverage even though this is a known issue with Hyundai engines.
I should have listen to all the noise in the market but instead I went any head and did it anyway. The start a knocking sound out of no where. My problem is why do they built these engines when one have to buy another one before the car even gets old enough.
