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

[VivienneRose]

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.
