We've got a fairly inexpensive bbq gas grill that's 4 years old. We just had to replace the gas regulator valve (it was leaking), the electric starter looks like it might be shorting out, and the grate plate (above the burners, below the ceramic grill) is either being burned away or eaten through from food drippings.
Structurally, it's fine. The burners still work, the cover still works, etc. So, what I'm wondering is: are there items on a grill, regardless of brand and price, that you have to replace anyway with heavy use? Even if we had a $2,000 grill, would some components still just wear out?
