Auto Shop Refuses Customer-Bought Parts; Owner Admits It’s to Protect Profit Margins

A family-owned auto repair shop in Michigan, USA, named Jerry’s Automotive, has recently sparked widespread debate. The shop explained on TikTok why it refuses to install customer-supplied parts, citing concerns over part quality, the risk of customers purchasing incorrect models—which disrupts workflow efficiency—and even drew an analogy: “You can’t bring your own steak to a steakhouse.” However, what truly ignited public backlash was the owner’s admission in the comments section that they do mark up parts, calling it a “reasonable markup” necessary to cover costs such as rent, equipment, and employee wages. A former auto parts store employee revealed that some repair shops sell parts for as much as 3.5 times their wholesale cost. While some industry insiders support this markup model, arguing it’s essential for business sustainability, most online commenters accuse shops of using “quality” and “warranty” as excuses to mask profit-driven motives. The video has already garnered over 50,000 views, and the controversy continues to escalate.
