1 Car Throttle Stuck problem of the 2018 Hyundai Sonata

Failure Date: 04/14/2019

I own this 2019 Sonata since 1/16/19. Was runing good at the first. But couple times start showing the engine light for seconds. But on April Sunday 14 2019 my car shows the engine light and the tire control stabilizer at the same time then the car start shaking lossing speed,the brakes getting hard and power steering. . Lucky I went at 10mph to 15mph. The vehicle will be placed in a temporary engine protection mode with reduced power and acceleration. No speed no acceleration then I park in a parking lot for towing at the nearest Hyundai dealership. Technitia found code( p0638 ) active code and (p211935002a00 throttle body carbon cleaning- adjustment and found rubber grommet stuck in the throttle body roved grommet. This cause trouble with the intake and injectors making the car limp and state in protection mode. I have lucky I wasn't in the freeway at 55,60 to 65 mph. O can be a different risk and dangerous for me and others drivers. Please take this note seriously before something worse can happen to others drivers . Thank you so much.

2 Car Throttle Stuck problem of the 2008 Hyundai Sonata

Failure Date: 10/30/2010

While driving our vehicle the throttle had stuck, I pulled on the floor mat as I was applying the brakes thinking this was the problem. This was not the case as the car wasn't slowing down. I popped the throttle with my foot hoping this would free up the throttle, which just made the problem worse. I placed the car in neutral and shut the engine off, kept applying the brake until I safely got the vehicle to stop. I had the dealership look into the problem that same day to find out that the computer chip had failed. I dont want this to happen to anyone.
