Will the 4S shop still be responsible if problems occur after maintenance outside?

The 4S shop will continue to be responsible if the car is still under warranty. However, it should be noted that the problematic part cannot be the one that was maintained outside. For example: if the engine and transmission were maintained outside and the car battery fails, the 4S shop should be responsible for it. But if the faulty part is the one maintained at an external repair shop, the 4S shop cannot be held responsible. Below is the significance of maintenance: 1. Regular maintenance can extend the service life of the car and reduce the failure rate. Maintenance items include the vehicle's fluids and consumable parts, which need to be replaced. 2. Long-term lack of car maintenance can lead to severe carbon deposits and greatly threaten the safety of the engine. Once it occurs, it can cause the engine to fail to work properly.

I previously owned a new car and tried to save money by getting it serviced outside. When problems arose and I took it back to the 4S shop for inspection, they said the warranty requires all maintenance to be done at authorized service centers, otherwise they wouldn’t cover it. After checking the maintenance manual, I realized it was clearly stated. Now I understand that for the first few years of a new car, sticking to 4S shop maintenance is the safest choice—their technicians are specialized, and the parts are OEM-matched, avoiding unnecessary disputes. If issues arise, small outside shops might not take responsibility, leading to higher repair costs. I recommend new car owners spend a bit more for peace of mind, saving the hassle later, especially since critical component failures can affect driving safety.

As someone who cares about consumer rights, I find this issue crucial. New car warranty terms typically stipulate that maintenance must be performed at authorized 4S dealerships, otherwise the dealership reserves the right to deny responsibility for faults caused by external maintenance. This relates to contractual agreements, and manufacturers establish these rules to ensure service quality control. I recommend car owners carefully read the warranty manual at the time of purchase and consult legal advisors if they have any questions. Don't overlook small details—if problems arise, it could be difficult to provide evidence and may affect the vehicle's residual value, directly impacting driving safety and personal financial burden.
