I have been a loyal weber grill customer for 40 years. I purchased a new s-400 series natural gas grill in 2016. its been 7 years and it is just falling apart. The first ss lid developed rust spots in the 2nd year and weber replaced it. The SS flavorizer bars are rusting out and need to be replaced. The IR burner which I have only used once will not light. The poorly engineered hidden rotisserie motor mount is so flimsy that the spit pops out of the motor during cooking. The grill itself has very uneven heat distribution. all the metal parts on the inside of the grill are rising out and to add insult to injury any grill bought prior to 2017 is not covered under the 10yr warrantee. Also this grill is on my deck and always covered with a weber cover 3rd one in 7 years as the don't hold up either.
