The windshield on my 2018 Honda Accord Hybrid Touring cracked spontaneously while it was being backed out of a downtown parking space. It has fewer than 7,500 miles on it. I'm told there is a 4 to 8 month backorder for an OEM replacement - the only kind that Honda will accept if I'm to maintain their warranty. Is this length of time excessive? Are there so many problems with Honda windshields that the supply chain can't keep up with the demand?
