Volvo uses ultra high strength steel (UHS) and boron steel in a lot of their components. The tensile strength of these parts changes when repaired and can only be cold straightened if straightened at all. If incorrectly repaired the metal can deform or fail during a collision that would effect airbag deployment timing and could allow more damage to transmit into the passenger compartment. The shop did the right thing standing their ground. I have been in the repair industry at a body shop for 20 years and the insurance company’s have shifted from doing the right quality repair to being about how cheap they can fix it. The big shift was during covid once the insurance company’s saw the profits from all the lockdowns and no one driving the wanted that trend to continue.
