Have had repairs done with the same problems and with oil leaking and burning badly so much as you can smell inside the vehicle while driving. It's a safety issue that could cause a fire.

My vehicle will suddenly drop in speed regardless of increasing gas, by adding pressure to the gas pedal. It is also making an odd noise from the engine. I took it to the mechanic who stated that they heard the noise but it was beyond their scope and I should take it to the dealer. I called the service department and told them the problem and also mentioned the lifetime engine warranty that Hyundai was pressured to offer. This was the statement for Hyundai at the Mall of Georgia. "Hyundai engine warranty is only on blown push rods." I stated what happens if the car suddenly dies or engine blows while driving 70mph on Interstate 85. All power being lost causing an accident and injuring or killing people. He stated, "I'm just telling you what Hyundai said!" This will cost Hyundai much more than engine replacement. I am suppose to here from them 12/30. I have been wait for two weeks after being put off twice. Please address for saving lives. Sending copies to media as well.
