Will a Dealer Warranty Cover OEM Parts vs Aftermarket Parts?
When your vehicle needs warranty repairs, the type of replacement parts used affects both quality and your satisfaction. Understanding how warranties handle parts helps you know what to expect.
OEM Parts Explained
Original Equipment Manufacturer (OEM) parts are made by or for the vehicle manufacturer. They're identical to the parts originally installed. OEM parts typically cost more but guarantee exact fit and function. Some warranties require OEM parts; others don't.
Aftermarket Parts Explained
Aftermarket parts are made by third-party manufacturers. Quality varies from excellent to poor. Good aftermarket parts meet or exceed OEM specifications at lower cost. Lower-quality parts may not fit or perform as well.
What Your Warranty Specifies
Check your contract for parts terms: 'OEM or equivalent' - allows quality aftermarket, 'Remanufactured or rebuilt' - repaired used parts may be used, 'New OEM only' - strictest and most expensive coverage, 'At administrator's discretion' - they choose.
Requesting Specific Parts
If you want OEM parts but your warranty allows aftermarket: you may be able to pay the difference for OEM, some contracts allow OEM requests with surcharge, and discuss options with the repair shop and warranty company before repairs.
Key Takeaways
- Warranty contracts specify parts requirements
- OEM parts cost more but guarantee exact fit
- Quality aftermarket parts may be acceptable

Frequently Asked Questions
Are aftermarket parts lower quality?
Not necessarily. Some aftermarket parts equal or exceed OEM quality. However, quality varies by manufacturer. The best aftermarket parts are certified to meet OEM specifications.
Can I refuse aftermarket parts?
You can request OEM, but may need to pay the price difference. If your contract specifies OEM, you're entitled to OEM parts.
What about remanufactured parts?
Rebuilt parts are cost-effective and often come with their own warranty. For many components (alternators, starters, transmissions), quality remanufactured parts perform like new.
