2. Non-OEM Modifications:

   • Coding changes that deviate from the OEM specifications or are intended to enhance performance beyond factory settings can potentially void the warranty.
   • Example: Modifying engine parameters to increase horsepower or disabling safety features can be considered non-OEM modifications.

3. Burden of Proof:

   • Manufacturers generally need to demonstrate that the coding changes directly caused the failure for which a warranty claim is being made.
   • This can be challenging, but if the modifications are significant and clearly linked to the issue, the warranty claim may be denied.

4. Dealer Discretion:

   • The impact on the warranty can also depend on the dealership’s discretion. Some dealerships may be more lenient than others regarding coding changes.

5. Specific Examples:

   • Voided Warranty: Significant modifications to the engine control unit (ECU) that result in engine failure are likely to void the engine warranty.
   • No Impact: Simple cosmetic changes, such as enabling certain lighting features, are less likely to affect the warranty.

6. Magnuson-Moss Warranty Act (in the US):

   • This act protects consumers by preventing manufacturers from voiding warranties unless they can prove that the aftermarket modification directly caused the failure.
   • However, this act primarily applies in the United States and may not be applicable in other countries.

7. Best Practices:

   • Keep a record of all coding changes made to the vehicle.
   • Consult with a trusted technician or coding expert before making any modifications.
   • Be aware of the potential impact on the warranty and weigh the risks and benefits.

8. Consulting with CAR-CODING.EDU.VN:

   • CAR-CODING.EDU.VN can provide guidance on which coding changes are less likely to affect the warranty and can help ensure that modifications are performed safely and within OEM parameters.
