The multitude of high performance equipment, as well as modern technologies integrated in the structure of vehicles, have led to an important change in their area of viability. These changes also have effects on maintenance work. Due to sensitivity of the electronic equipment to environmental, temperature and working conditions, it is necessary to adopt effective solutions to protect them and maintain their state of operation. The major challenge among classic vehicles, but also hybrid or electric is the thermal management of this equipments. IoT is a strategic concept for the future of communications between the various functional systems of society, which will adapt and regulate vehicle traffic in relation to the environment. IoT technology will generate certain job opportunities for predictive vehicle maintenance. The research is a subjective, well-documented analysis, based on which some appropriate measures are proposed for the future, regarding the maintenance process of vehicles. In this direction, the preventive nature of actions and the implementation of 5G / 6G technologies at a global level are pursued. Also, the implementation of hardware and software solutions in the structure of vehicles is considered. They aim to adapt the operation of vehicles to the optimal parameters, by applying preventive corrections.
