Q: What is making my engine knock?

asked by on October 29, 2015

Every time I start up my 2010 Chevrolet Silverado, there is a knock in the engine. The truck is only at 15,000 miles! I am very concerned, as the truck is very new and hasn’t missed an oil change or any scheduled maintenance. I need to fix this problem right away. Is this a common problem or is this truck a lemon?
