I have owned this grill for 9 years, use it 2-3 days per week, slow cooked pork tenderloin, rotisserie chicken, and burgers. After 9 years of use the burners needed replacing, corrosion holes through the bottom housing.  Customer service sent me the new pieces. No charge for parts or shipping!  They honor their warranty.  I replaced a few additional parts not covered.  Well worth it. I am looking forward to another 10 years of use!
