What is the national standard for the warranty period of auto parts?
3 Answers
For household automotive products, the warranty period shall not be less than 3 years or 60,000 kilometers of mileage. Below are the relevant details: 1. Warranty: During the warranty period of household automotive products, if any quality issues arise, consumers can obtain free repairs (including labor and material costs) from the repairer by presenting the three-guarantee certificate. 2. Replacement of parts: Within 60 days from the date of purchase invoice issuance by the seller or within 3,000 kilometers of mileage (whichever comes first), if major components of the engine or transmission have quality issues, consumers may choose to replace the engine or transmission free of charge. The types of major components of the engine and transmission shall be clearly indicated by the manufacturer on the three-guarantee certificate, and their scope shall comply with relevant national standards or regulations. Specific requirements shall be stipulated separately by the General Administration of Quality Supervision, Inspection and Quarantine.
I have researched the automotive three-guarantee policy, and there is no separate national standard for the warranty period of auto parts. Currently, it mainly follows the "Regulations on the Repair, Replacement, and Return of Household Automotive Products." The warranty for the entire vehicle is 3 years or 60,000 kilometers, but the warranty periods for specific parts vary. Core components like the engine and transmission may follow the vehicle warranty, while wear-and-tear parts such as wiper blades and brake pads usually only have a warranty of 3-6 months. The most reliable approach is to carefully review the maintenance manual when purchasing a car, as it will detail the warranty period for each component. If the dealership promises a longer warranty period than the manual states, make sure to have it written into the contract—verbal promises don’t count.
Our fleet has been managing vehicle maintenance for over a decade, and there's actually no unified national standard for parts warranty. It's basically divided into three scenarios: original parts are covered under the vehicle warranty during the warranty period, wear-and-tear parts have shorter separate warranty periods (like tires, which are only 3 months), and parts replaced in accident repairs are covered according to the repair contract terms. Last time, my colleague replaced an alternator, and the 4S shop offered a 1-year warranty. I recommend always asking for warranty documentation when replacing parts—standard parts usually come with at least 3 months of coverage, while critical components typically have 1 year or more. Keeping repair receipts is especially important, as they serve as crucial evidence when you need to assert your rights in case of issues.
