Why Car Ownership Myths Persist
Some driving beliefs are passed down like family heirlooms — repeated confidently at dealerships, in parking lots, and across kitchen tables. The problem is that many of them are simply wrong, and acting on bad information can cost real money. Whether you're a first-time buyer or a driver with decades behind the wheel, a few stubborn myths deserve a direct rebuttal.
For a broader look at what vehicle ownership really costs, see our full breakdown of ownership costs beyond the sticker price. What follows corrects some of the most persistently misunderstood ideas about owning and maintaining a car.
Myth
Red cars cost more to insure because insurers see them as a higher risk.
Fact
Insurers do not factor in vehicle color when calculating premiums — it simply isn't part of the rating formula.
This myth is remarkably widespread, yet no major US insurer includes paint color as a rating variable. What actually drives your premium includes your driving history, the vehicle's make and model, its safety features, your location, and your annual mileage. If you're curious about what genuinely moves the needle on insurance costs, the variables are more nuanced than you might expect.
Myth
Missing a single scheduled service automatically voids your manufacturer warranty.
Fact
One missed service does not automatically void a warranty, but documented neglect that causes a specific failure can allow a manufacturer to deny a related claim.
Under the federal Magnuson-Moss Warranty Act, manufacturers cannot void an entire warranty simply because you missed an interval or used an independent mechanic. However, if a missed service directly contributes to a mechanical failure — for example, skipping oil changes leading to engine damage — the manufacturer may deny coverage for that specific component. Keeping maintenance records is your best protection, regardless of where the work is done.
Myth
You must warm up a modern car by letting it idle before driving in cold weather.
Fact
Modern fuel-injected engines warm up faster and more efficiently under gentle driving load than they do sitting idle.
Idling to warm up made sense with older carbureted engines, but fuel injection systems have made it unnecessary. Extended cold idling can actually wash oil off cylinder walls and introduce unburned fuel into the engine. The better approach: start the engine, allow 30 seconds or so for oil to circulate, then drive gently until the temperature gauge reaches its normal range.
Myth
High mileage is always a red flag and means a car is near the end of its life.
Fact
A well-maintained higher-mileage vehicle can significantly outlast a neglected low-mileage one — service history matters far more than the odometer reading alone.
Many modern engines are engineered to run reliably well past 150,000 miles with proper upkeep. When evaluating any used vehicle, service records, the quality of past repairs, and a pre-purchase inspection by a qualified mechanic tell you far more than mileage alone. Our article on the financial logic behind high-mileage ownership explores when holding onto an older vehicle makes sound financial sense.
Myth
You must take your new car to the dealership for servicing to keep the warranty valid.
Fact
You are legally entitled to use any qualified independent mechanic for routine maintenance without voiding your new car warranty.
Again, the Magnuson-Moss Warranty Act is clear on this point. Dealerships cannot make warranty coverage conditional on exclusive use of their own service department. What matters is that the work meets the manufacturer's specifications and that you retain proof of service — receipts, invoices, or a service logbook. Dealer servicing may be convenient or preferred by some owners, but it isn't legally required.
What the Myths Get Wrong — and What Actually Matters
The myths above share a common thread: they each push drivers toward unnecessary spending or, worse, away from genuinely useful habits. Understanding how warranties, insurance pricing, and engine mechanics actually work puts you in a far stronger position when making ownership decisions.
40%+
Of drivers believe car color affects insurance cost
Consumer surveys consistently show a significant share of drivers hold this misconception, despite color being absent from insurer rating models.
150,000+
Miles many modern engines are designed to last
With regular servicing, many contemporary vehicles are engineered to reliably reach high-mileage milestones that would have been exceptional a generation ago.
Warranty protection in particular is widely misunderstood. The Magnuson-Moss Warranty Act prevents manufacturers from voiding a warranty simply because you used an independent service shop or non-OEM parts — provided those parts and services meet the manufacturer's specifications. You can read more about the real consequences of skipping maintenance in our guide on what happens when you skip scheduled servicing.
Your Warranty Rights Under Federal Law
The Magnuson-Moss Warranty Act gives US consumers meaningful protection against overreaching warranty restrictions. Manufacturers cannot require you to use their dealers for routine servicing as a condition of keeping your warranty in force. If a dealer or manufacturer implies otherwise, ask for that claim in writing — it's unlikely they'll provide it. When in doubt, consulting a consumer protection attorney or your state's attorney general office can clarify your rights.
Good ownership habits don't require mythology. They require accurate information and consistent follow-through. Our guide on habits that keep a car running well covers the practices that genuinely make a difference — none of which involve idling in the driveway or avoiding independent mechanics.

Don't Let Myths Replace Actual Maintenance
Debunking myths isn't a license to skip maintenance altogether. Knowing that one missed service won't void your warranty is different from making a habit of neglecting your vehicle. Consistent upkeep — oil changes, tire rotations, brake inspections — remains the single most reliable way to extend vehicle life and avoid costly repairs. Check your owner's manual for the intervals that apply to your specific vehicle.
