Keep in mind that only the belt material has been changed. The seatbelt mechanism is still Honda/Acura. Generally, seatbelts don't falter. If in an accident and the mechanism goes off then you would need to replace anyway. So I do not think warranty is an issue here. As for insurance, again these are not aftermarket mechanisms. If you are thinking the webbing will fault and break, you are probably dead if that happens and warranty is not so much an issue for you. If your heirs are in court and trying to sue the shop that replaced the seatbelt color with another, they would have to prove that the mechanism or belt material failed as a result of the color change. Or they would have to prove that the belt material used was insufficient for this specific purpose. A good lawyer would sue everyone and hope that deep pockets prevail. SeatBeltRestore uses belt material manufactured for this particular purpose (seatbelts) and meets Federal Guidelines. Also, Honda/Acura have deep pockets compared to a shop and the focus would be on how their seatbelt design or function resulted in someone's death or serious injury.
