The Magnuson-Moss Warranty Act prohibits product manufacturers from conditioning consumer warranties on the use of any original equipment part or service. Furthermore, a manufacturer can only deny warranty coverage if it can demonstrate that a non-original equipment part or related service caused a defect to occur in the original product. In the case of motor vehicles, new car manufacturers have ignored these conditions outlined in Magnuson-Moss and have misled consumers to believe that they must have dealer service shops install only original equipment replacement parts or fear having their new car warranty voided.

As-Is Vehicle Purchase: With an as-is purchase, once you leave the dealership, all repairs and maintenance are the owner’s financial responsibility. There is no warranty to assist with the cost of repairs.

What is the Magnuson Moss Warranty Act and how does it affect me?
The Magnuson Moss Warranty Act is a consumer protection law enforced by the Federal Trade Commission. The federal Act outlines the clear and easy-to-understand terms that a written warranty must include such as:
- Who is covered by the warranty
- A clear description and identity of what’s covered
- Responsibilities of the warrantor and the consumer, including where and how repairs and maintenance can be performed
- Warranty expiration
- Ways to handle disputes with the warrantor
For more information on the Act, visit the Federal Trade Commission’s
website and view the Car Care Council’s
What is the difference between aftermarket and original equipment manufacturer (OEM) parts?
OEM parts are produced by or for the vehicle manufacturer and are labeled with the name of the manufacturer. Aftermarket parts are produced independently of the vehicle manufacturer and are labeled under the brand name of the manufacturer of the part.
Do aftermarket parts meet OEM specifications?
Some aftermarket parts meet or exceed the requirements of OEM parts. If you have questions regarding the quality of a part, you should confer with your repair shop or the salesperson who sells you the part at a parts retailer.
Am I required to follow the manufacturer's maintenance schedule in order to maintain my factory/dealer warranty?
Yes. You should follow the manufacturer's routine maintenance schedule; however, you can have your vehicle maintained at any certified repair shop. You are not required to obtain non-warranty-related services at the dealership.
What is the difference between my manufacturer/dealer warranty and my insurance policy?
There are many differences between a warranty and insurance. The major difference is that a warranty covers certain mechanical breakdowns, and the parts and labor repair cost. Insurance coverage helps to repair your vehicle if it’s damaged by a specific cause such as an accident, theft, etc.
For specifics on your warranty, contact the manufacturer or dealer; for more information on your insurance policy, contact your insurance agent.
Do repairs that are covered by the warranty have to be completed at the dealership?
The manufacturer or dealer may require consumers to use select repair shops if the services are provided for free under the warranty. However, you can have your vehicle serviced at any certified repair shop for non-warranty repairs. You are not required to obtain service at the dealership.
If I do not get my vehicle serviced at a dealership, how will I be able to prove I have done the recommended maintenance on my car?
Record all maintenance and repairs that are completed on your vehicle and save the receipts for the service. Ensure the receipts are clearly dated and list an accurate description of the parts supplied and service performed. It is important to remember that the manufacturer or dealer, and not the consumer, is responsible for demonstrating that a failure due to use of a non-OEM related part or service, actually caused the failure.
