First, the quality problem.
First of all, all the cars bought by men have corresponding quality problems, because the existence of these car quality problems may lead to some specific safety accidents, such as some cars can't be locked, or cars can't start normally, or the shock absorbers of cars have problems, which will bury corresponding safety hazards for the subsequent use of cars and endanger the life safety of car owners, so car owners need more help and quality inspection of cars more often.
Second, men don't know how to operate.
Some cars are smarter cars. For some high-end brands, more cultural knowledge is needed to better use them in the process of use, because the cars of these brands will involve more high-tech use in the process of research and development, so for car owners, what they need more is to be familiar with the basic operation of the car, even some advanced operations, so that they can better operate the functions of the car after learning.
Third, people nearby interfere with their signals.
If there are criminals in the nearby crowd who interfere with the signal of the car, it will inevitably lead to the problem that the car can't close when it closes. Once this problem occurs, drivers need to call the police immediately, because such criminals have some illegal purposes when using some signal jammers, the main purpose is to better interfere with cars and steal cars.
Note: after a series of tests, we can find out whether there is a problem with the quality of the car. If there is a problem in the village, we can let it provide corresponding treatment. If there are operational problems, you can consult the corresponding master in time.
