The details
How we count
Every number here is a repair bill an owner reported, never a shop's price list. Two sources: the bills owners wrote in their own complaints to the U.S. government (NHTSA), and the dollar amounts owners said out loud in YouTube repair and ownership videos. A figure counts for a repair when that repair is the part named nearest to it. Left out: purchase prices, payments, rentals, towing, warranties and deductibles, amounts under $50 or over $15,000, parts-only prices ("the part was $80 on Amazon"), bills for two different repairs named together, and money someone else paid. One number per complaint (or video) and repair: the biggest, so it's the bill, not the diagnosis fee.
The range is the middle half of the bills (the 25th to the 75th percentile), so one wild number can't swing it. Owners who complain to the government often had expensive repairs, so a typical bill can be lower. Costs vary by shop and region, by dealer vs independent shop, by parts and by miles. This is what owners reported, not a quote for your car.
