At about 80,000 miles, the vehicle started making a loud and constant knocking sound in the engine. The Hyundai dealership service department determined that: "internal rods are making knocking sound - engine must be replaced." This very loud knocking happens all the time whether the vehicle is stationary or moving. The vehicle is not safe to drive. This issue is identical to the 2015 recall of many other Hyundai vehicles from the same model year (I.e. NHTSA campaign number: 15V568000). Hyundai denied this claim since the vehicle is out of warranty. Hyundai Consumer Affairs case#: 10847090.

After starting the engine and tapping on the accelerator, the car will accelerate on it's own and rev up to 1,500-2000 RPM without pressing on the accelerator. Even when braking. Returning the car to neutral causes the engine to rev up to or beyond 2,000 RPM until the vehicle has been turned off. This incident first occurred in April 2016. I was told there was an issue with the sensors by the Hyundai dealership. The issue resurfaced again in January 2017. This time they told me it was due to a carbon buildup in the fuel system. Now it's doing it again. I have seen many other reports of this happening to hyndai's on the internet. This is a huge safety issue.

The contact owns a 2012 Hyundai Accent. While operating the vehicle, the vehicle accelerated on its own. While parked, the vehicle would rev to approximately 5,000-6,000 rpms even when the brake pedal was depressed or when the vehicle was in another gear. The only way to stop the failure was to remove the key from the ignition. The failure occurred without warning. The vehicle was taken to the dealer where it was diagnosed that the throttle body needed to be cleaned. The vehicle was repaired; however, the failure recurred. The manufacturer was not notified of the failure. The failure mileage was approximately 61,000.

Around 50000 miles the car would over rev about 1000-2000 RPM when the clutch was released and foot off of the gas. It has progressively gotten worse. Now it will on its own while standing at idle run up to 5000-6000 RPM without warning and the only way to stop it is to turn the car off. When in gear, the car will accelerate without warning. If you depress the clutch, again it will run up to 5000-6000 RPM. The problem becomes exacerbated in warmer weather and lessened in cold weather. During the 12/24 heat wave here in pa, the car was undriveable and dangerous as I could not depend on it not "taking off". the dealer updated the software on 12/22 which did not resolve the issue, and no codes were found in the computer! before 50,000 miles everything was fine.
