" 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. "
