Is Car Rust Covered Under the Three Guarantees Policy?

[DiManuel]

Car rust is covered under the Three Guarantees policy. It is recommended to consult the 4S store first. If there are other requirements and the repair solution is not accepted, you can contact the manufacturer for further handling. The causes of car rust are generally related to manufacturing processes and usage environments. The specific reasons can be assessed by an independent third-party appraisal agency. If it is indeed caused by non-human factors during the warranty period, it falls under the warranty coverage, and the 4S store usually handles it for free. New Three Guarantees Law for Cars: Vehicle Replacement - If the same fault is repaired more than 5 times, the car can be replaced. During the Three Guarantees validity period, if the cumulative repair time exceeds 35 days or the same product quality issue leads to more than 5 repairs, the consumer can request a replacement. Within 60 days from the date of the purchase invoice or within 3,000 kilometers, whichever comes first; Vehicle Return - If the engine is replaced twice and still does not function properly, the car can be returned. During the Three Guarantees validity period, if severe safety performance faults are repaired twice but remain unresolved or new severe safety performance faults arise; or if the engine or transmission is replaced twice; or if the same major component of the steering system, braking system, suspension system, front/rear axle, or body is replaced twice due to quality issues and still does not function properly, the consumer can choose to return the vehicle, and the seller shall be responsible for the return. If a household vehicle meets the replacement conditions but the seller does not have the same brand and model or a product with a configuration not lower than the original vehicle, the consumer can choose to return the vehicle, and the seller shall be responsible for the return. If repairs take more than 5 days, the owner has the right to use a replacement vehicle. During the warranty period, if a household vehicle has product quality issues, the consumer can use the Three Guarantees certificate to receive free repairs from the repairer, including labor and material costs.

I remember my old car started to rust underneath after more than five years of use. At first, I thought it was a minor issue, but it got worse over time. Later, when I took it to a repair shop, I learned that if the rust was caused by manufacturing defects, such as poor anti-corrosion coating or material issues, the manufacturer would have to repair or replace the parts for free within the warranty period. However, once the warranty expired, it became a hassle. If the rust was due to my own negligence in maintenance, like frequently parking in damp areas or not addressing scratches, it wouldn’t be covered under the warranty, and I’d have to pay out of pocket. My advice is to regularly inspect the paint and chassis of a new car, especially before and after the rainy season, and keep records of each maintenance session. This way, if issues arise, it’s easier to argue with the dealer—don’t wait until the rust eats through to regret it.

The three-guarantee policy essentially means the manufacturer's warranty for product defects. Whether rust on a car is covered depends on the specific cause. If rust appears shortly after purchasing a new car, especially in concealed areas like door seams or the chassis, it's likely due to inadequate rustproofing during production and should be repaired for free within the warranty period. However, if the rust stems from external factors like scratches, seawater corrosion, or improper maintenance, the manufacturer won't cover it. Consumers should carefully review the vehicle warranty manual and owner's manual, which clearly outline the coverage. Additionally, regular car washing and avoiding parking in waterlogged areas can reduce risks, but don't expect the three-guarantee policy to cover everything—prevention is key.

Having worked in auto repair for many years, rust issues are common. If rust appears within the first couple of years on a new car, it's usually the manufacturer's responsibility and covered by the warranty policy. However, for older cars or cases of owner neglect—like failing to wash off salt or touch up paint promptly—rust repairs are out-of-pocket. Regular checks for paint cracks and early treatment are recommended.

Preventing car rust is key to avoiding disputes over the three guarantees. Avoid parking in damp roadside spots daily, and wash your car promptly after rain to remove dirt. If rust spots appear, apply rust inhibitor for minor issues yourself; for major problems, first check the warranty period. The three guarantees only cover rust due to manufacturing defects, such as lack of rustproof coating or faulty parts, not rust from improper maintenance. Developing good habits saves both hassle and money.

After driving for a long time, I realized that parking habits affect rust risks. I always avoid parking in puddles or coastal areas, and I don't expose my car to direct sunlight in summer, so the paint is less prone to aging and rusting. If the car body does rust, can the three-guarantee policy help? The answer depends on whether it's the car's own issue, such as production defects or incomplete rustproofing. Within the warranty period, it can be repaired for free, but rust caused by scratches or lack of maintenance is on you. It's recommended to check after each car wash and apply sealing treatment if necessary.
