An independent repair facility, a retail chain shop, or even you yourself can do routine maintenance and repairs on your vehicle. In fact, the Magnuson-Moss Warranty Act signed into law in 1975), and enforced by the FTC, makes it illegal for manufacturers or dealers to claim that your warranty is void or to deny coverage under your warranty simply because someone other than the dealer did the work. The manufacturer or dealer can, however, require consumers to use select repair facilities if the repair services are provided to consumers free of charge under the warranty.
If you own a car, you know how important it is to keep up with routine maintenance and repairs. But can a dealer refuse to honor the warranty that came with your new car if someone else does the routine maintenance or repairs?
The Federal Trade Commission (FTC), the nation's consumer protection agency, says no. In fact, it's illegal for a dealer to deny your warranty coverage simply because you had routine maintenance or repairs performed by someone else. Routine maintenance often includes oil changes, tire rotations, belt replacement, fluid checks and flushes, new brake pads, and inspections. Maintenance schedules vary by vehicle make, model and year; the best source of information about routine scheduled maintenance is your owner's manual.
