There is a lot of electronics in modern cars and they are likely to grow in the future. Therefore, it should not be surprising that the more electronics in the car, the more malfunctions in the system. Car electronics troubleshooting is best left to us rather than trying to repair it ourselves. The cost of electronics repairs depends on the type of system failure and how difficult it is to replace. It is often the case that a small detail breaks down at first glance, but it does not result in more components.
