2015 Hyundai Genesis Coupe Owner Complaints

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. My case number with hyundai [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

AFTER REFUELING MY VEHICLE ON THE EVENING OF 11/09/2017, THE HEADLIGHTS WOULD NOT COME ON USING THE "AUTO-ON" FEATURE. THEY DID WORK WHEN SWITCHED TO "ON".

THE DOORS WOULD NOT LOCK AND THE SEAT BELT LIGHT WAS ON "CONSTANT" AND THE SEAT BELT CHIME WAS AUDIBLE FOR (15) MINUTES OF THE (30) MINUTE DRIVE. THE INTERIOR LIGHTS (DASH) WERE AT FULL BRIGHTNESS AND COULD NOT BE DIMMED. THE FACTORY GPS WAS LOCKED IN "PREPARING" MODE.
