Cracked frames discovered in 3 year old Vicinity buses. This is not a great sign at all. 3 year old, heavy duty buses should not have major frame issues like this. A huge warranty expense for the company especially if other customers have this issue at all. The Altoona bus test report for the 35ft version (report number 1902, on the Altoona test website) also stated multiple issues with frame cracks. https://panow.com/2021/04/30/entire-fleet-of-p-a-transit-buses-affected-by-cracked-frames/
