In some cases, the staff of car 4S shops or car dealers use WeChat and other methods to register, so as to better use cars to explain the software of OnStar system. This situation can also be handled by contacting the salesman or the customer service staff of Anjixing. There are also some cases of returning cars. This situation is that other car owners have registered in the past, and it is very likely that they no longer need this car. This will happen frequently.
However, this kind of situation is rare, even if the car is returned, it will not endanger other characteristics of the car, because the owner just bought it before and has not signed the application for the car pick-up process. At most, I tried it at a car 4S shop or a car dealer.
