In the age of online shopping, it’s tempting to think you can save money on your next car repair by purchasing your own parts and asking a shop to install them. After all, car parts are widely available online—so why not bring your own and just pay for labor?
While this might sound like a smart, budget-friendly move, the reality is much different. At Franklynn Automotive in Littleton, Colorado, we often explain to customers that bringing your own parts can actually cost more in the long run—and for good reason. Between warranty issues, fitment problems, and lack of protection for both you and the shop, it’s simply not worth the risk.
Let’s take a closer look at why bringing your own parts doesn’t work in modern auto repair, and how professional shops protect you by sourcing parts the right way.
Warranty Protection: The Biggest Reason to Let the Shop Provide Parts
When you bring your vehicle to a professional auto repair shop like Franklynn Automotive, every repair is backed by both a parts warranty and a labor warranty. That means if something goes wrong—a defective part, early wear, or a malfunction—the shop covers the cost of replacement and installation.
But if you bring your own part, that warranty protection disappears.
- No warranty on labor: If a part you brought in fails, the shop isn’t responsible for reinstalling it for free.
- No warranty on parts: Online sellers may not honor a warranty unless a certified shop purchased and installed the component.
- You take all the risk: You’ll end up paying twice—once for the original labor and again for reinstallation if the part fails.
When we source parts at Franklynn Automotive, we only use high-quality components from trusted suppliers that offer nationwide warranties. That means you’re covered even if you’re traveling outside of Littleton.
The Fitment and Quality Problem
Not all parts are created equal. Online marketplaces often list aftermarket parts that claim to fit a wide range of vehicles—but in reality, tolerances can vary greatly between brands and manufacturers.
Common problems with customer-supplied parts include:
- Incorrect size or fit
- Incompatible sensors or electrical connectors
- Low-quality materials that wear out prematurely
- Missing installation hardware or gaskets
Even a small mismatch can cause serious issues. For example, an incorrectly sized brake rotor or belt can cause noise, vibration, premature wear, or even safety hazards.
Professional shops have direct access to verified parts databases and VIN-specific catalogs, ensuring that every component fits your exact make, model, and year.
Shop Liability and Safety Standards
Auto repair shops are held to strict safety and legal standards. When a shop installs a part, they are responsible for the performance and safety of that component. If a customer brings their own part, the shop has no way to verify its origin, quality, or prior handling.
That’s why most reputable repair facilities—including ours in Littleton, CO—won’t install customer-supplied parts. It’s not about profit—it’s about protecting your safety and our reputation.
If a customer-supplied part fails and causes an accident or damages other components, the shop could be held liable, even though it wasn’t their part. To avoid this kind of risk for both parties, most shops maintain a clear policy: we provide and install the parts we can guarantee.
The “Hidden Costs” of DIY Part Purchases
Buying parts online might seem cheaper at first glance, but those savings can quickly disappear when you factor in:
- Shipping costs and delays
- Restocking fees if you order the wrong part
- Extra diagnostic time if the part doesn’t fit or function properly
- Repeat labor costs if the part fails prematurely
When you let the shop handle sourcing, you benefit from their relationships with professional distributors—meaning faster delivery, better pricing, and guaranteed quality.
The Colorado Right to Repair Act: What It Really Means
Some drivers in Colorado point to the Right to Repair Act, which ensures consumers can choose where and how their vehicles are repaired. While this law gives you the freedom to use independent repair shops instead of dealerships, it does not require shops to install customer-supplied parts.
In fact, the law was designed to empower independent auto shops by granting access to manufacturer repair data and diagnostic tools—not to force them to work with parts they can’t verify or warranty.
So even under Colorado’s Right to Repair Act, the best protection for your vehicle and your wallet comes from partnering with a reputable shop that provides both parts and labor guarantees.
Our Littleton tire shop offers a full range of tire services—from inspections and rotations to replacements—helping you stay safe on Colorado’s roads.

FINAL THOUGHTS: Quality and Safety Are Worth It
