Repair shops can't get parts for 2-6 weeks, leaving customers stranded without cars

Independent repair shops and even dealerships regularly face 2-6 week backorders on common replacement parts — not just for exotic vehicles, but for mainstream models like Toyota Camrys and Ford F-150s. So what? A customer brings in their car for a failed alternator or a leaking water pump, and the shop discovers the part is on national backorder with no ETA. So what? The customer's car sits on a lift or in the lot, occupying bay space the shop can't bill for, while the customer scrambles for rental cars or rides. So what? Rental car costs of $40-$80/day for 3-4 weeks add $840-$2,240 to what should have been a $500 repair. So what? Shops lose revenue from tied-up bays and frustrated customers who blame the shop for delays beyond their control, damaging the shop's reputation and customer retention. So what? Some shops resort to sourcing parts from junkyards or unknown third-party sellers, introducing quality and counterfeit risks. This persists because the automotive parts supply chain consolidated around just-in-time inventory models, and post-pandemic disruptions, semiconductor shortages, and tariff uncertainties have never fully resolved, leaving thin buffers for demand spikes.
