Not nationwide applicable. The free maintenance services provided by the 4S store can only be used at the designated 4S store for after-sales service. Below is the relevant introduction about car maintenance: 1. Main items: Replace engine oil and oil filter, air filter, gasoline filter, transmission oil, and tire maintenance. 2. Purpose of maintenance: The purpose of car maintenance is to keep the car clean and in normal technical condition, eliminate hidden dangers, prevent failures, slow down the deterioration process, and extend the service life. 3. Importance: Daily car maintenance is very important. A slight negligence in daily maintenance will not only cause unnecessary damage to the vehicle and shorten the service life of the car but also endanger driving safety.

Regarding the issue of the six free maintenance services being valid nationwide, I also encountered a similar situation when I bought my car. Generally speaking, it depends on the contract signed at the time of purchase and the brand's policy. Some major brands like Toyota or Volkswagen usually offer nationwide coverage, allowing maintenance at any authorized dealership; for example, the free maintenance I received last time allowed me to easily change the oil at an out-of-town dealership without any restrictions. However, some smaller brands or specific promotions may limit the services to the purchasing dealership or local area only. For instance, a friend who bought a domestic brand car had the maintenance card clearly stating that services must be performed at the original dealership. So, the key is to check the terms of the freebies in advance or call the dealership to confirm, to avoid a wasted trip. Additionally, routine maintenance like oil changes and filter replacements can usually be done nationwide, but special services might be exceptions. It's advisable to ask the salesperson when picking up the car and keep all receipts, so you can present the records if necessary to assert your rights. Don’t wait until the service is about to expire to panic—early verification saves hassle.

I understand everyone's concern about the universality of maintenance, as it involves convenience. Different car brands handle it differently: premium brands like Mercedes-Benz or BMW are mostly nationwide, as their service networks are extensive, and their interconnected systems can identify and record maintenance history; economy brands like BYD or Great Wall sometimes restrict it to local dealers. From my own experience, check the maintenance manual or e-coupon—usually, the rules of use are clearly stated in the app, specifying whether cross-province service is allowed. If unsure, directly contact the service hotline or WeChat customer service—they can check the system for confirmation. Some 4S stores limit the scope to retain customers, which is unfair but a reality. Fortunately, consumer protection laws safeguard basic service interoperability. In short, don’t just rely on verbal promises from salespeople—written terms are more reliable. Make it a habit to read the agreement carefully before picking up the car, ensuring a worry-free driving experience.

Common issues with complimentary maintenance services can be easily resolved by checking the details on the maintenance card or app. Most brands allow nationwide usage, especially within authorized 4S dealership chains. If the contract doesn't specify restrictions, it's generally acceptable. For example, when I go for maintenance, I just present the coupon code, and the staff scans it – no location restrictions. However, it's wise to confirm before purchase to avoid issues during business trips. Ensure the service includes routine items like oil changes, and don't assume it covers everything. A simple check can clear up any doubts.
