These days, highly distributed control units (ECUs) with intricate hardware parts are seen in cars. Most cars have more than 125 ECUs, which take up a lot of room. Integrating ECUs can handle a variety of tasks from a single device, including dashboard, head-up display, rear-seat entertainment, augmented reality, and in-car entertainment. The expansion of the automotive electronic control unit market is fueled by this integration, which removes requirements for GPU, CPU, and camera as well as broadband network interference. 

One major restraint of the automotive electronic control unit (ECU) market is the increasing complexity and sophistication of the ECU's software. As the ECU's software performs a growing number of functions, it becomes more complex, leading to technical problems with automobiles. The complexity of the ECU's network structure and connectivity issues, caused by the increasing number of ECUs in vehicles, also presents a challenge. Technical flaws in the ECU can result in issues such as unintended acceleration, increased fuel consumption, unintended airbag deployment, and decreased vehicle performance, further restraining the market growth. 

The engine's fuel level and timing may become invalid due to an automobile electronic control unit failure, which would impair the vehicle's performance. This could result in sporadic problems with the car, such as a stall or fire. Power loss, acceleration, and fuel efficiency can all result from ECU failure. Most associated controls have an impact on one another, and the control units are extremely complicated. Thus, the car may start if the control unit malfunctions totally or is tampered with. To a great extent, there is no auxiliary backup to account for human error because the car with ECU function has no additional financial load. Thus, a defective control unit could result in potentially deadly issues like activating airbags when they are not needed. Customers must bear additional costs because of these unit failures. As a result, this could impede the market's expansion for car body electronics.
