Warranty is an obligation imposed by law upon the manufacturer of a product. This legal basis forms the foundation for the sales terms and conditions used by Daimler AG, and these contracts form the basis for any legal claims filed by buyers of Mercedes-Benz product. It means that Daimler or Daimler official agent is liable for ensuring that any product sold complies with the conditions of the sales contract. Daimler or official Daimler agent is liable for defects that existed at the time of sale even if these do not become obvious until a later date that is within the period given for warranty. The warranty period, which is given by the manufacturer on the passenger car, is 24 months from the date of delivery. The date of delivery can be translated to the date of the first registration or initial operation, whichever comes first. The warranty, which is provided by the manufacturer to the commercial vehicle, is subjected to the sale terms & conditions.

The warranty is limited to a "freedom from defects upon delivery corresponding to the level of technology for comparable vehicles of the model of the vehicle sold". This also means that unavoidable production tolerances, which series production has to be subject to and structural conditions which do not impair the vehicle characteristics in any way, are not eligible under the warranty.

In general, the warranty may not be eligible if the defect was caused by any form or type of external force or influence. For example, following cases may be considered.
