After 2 years of owning my new 2011 Honda Accord, I noticed a grinding sound during cold starts that lasted 1-2 seconds and then stops. I have the dealership inspect the problem but they quickly dismissed and said the noise was being made by the vtc and to not worry about the noise. In addition, they said that no harm would be caused by the noise. Now I have over 100,000 miles on the car and the noise is on every cold start no matter what the temperature and last for 2-5 seconds. I recently called the dealer and they indicated that if the vtc was the problem (which it has been all along), then I would need to pay in full for the repair since it is out of warranty.
