This is a new Hyundai Sonata 2015. The engine check light came on and the engine started running erratically. The following symptoms can be a safety concerns: 1. sometimes when idling at intersection the engine RPM goes up all of a sudden and the car starts moving forward and only a stronger push on the brakes stops the car from crashing into the vehicle ahead or running a red light. 2. when driving on highway the car lacks power even if the gas pedal is depressed all the way into the floor. This prevents the car from properly accelerating when merging into incoming traffic. I took the car to the dealership and they identified the issue is "cam cover leaking" and "oil coming through the oil seal making the motor do weird things". these are the quotes from the paper I got from the dealer. The car spent 2 weeks with the dealer. They replaced the cam cover. But 2 days later the problem appeared again. I'm afraid of driving this car now, because engine behaves erratically. And this car only has 3500 miles on it.
