About Repair and Maintenance
Every car is slowly wearing out, and the difference between one that lasts 100,000 miles and one that sails past 250,000 is mostly attention. Fluids, filters, tires, brakes and batteries ask for little but punish neglect, and the average car on American roads is now well over a decade old. That makes maintenance and repair a bigger part of ownership than ever. This section covers the work of keeping cars running, from routine service to major repairs and the do-it-yourself crowd.
Cars have become far more durable over the decades. Engines that once needed tune-ups, points and frequent oil changes now run long service intervals on synthetic oil, and rust, the great killer of older cars, has been pushed back by galvanized steel and better coatings. But complexity has risen in step: turbochargers, direct injection, eight- and ten-speed transmissions and dozens of computer modules mean that a modern repair often starts with a diagnostic scan rather than a wrench.
The industry around repair is changing just as quickly. Independent shops and owners have fought automakers for access to diagnostic data and parts in the right-to-repair movement, which won a landmark ballot measure in Massachusetts. Technician shortages, rising labor rates and higher parts costs have pushed repair bills up. Electric cars remove oil changes and many wear items but bring new concerns about battery health, tire wear and specialized service.
The pages below divide the subject into routine maintenance, repairs and parts, and DIY guides. Together they follow service bulletins, warranty fights, shop economics, parts supply and the practical how-to articles that save owners money and frustration. The common thread is money and time: a little knowledge about what a car needs, what a fair repair price looks like and which problems a given model is known for can save owners a great deal of both over the years.
