![]() Clearly, a malfunction in this feature could lead to an unexpected twisting force and potentially cause crashes. For example, Mercedes-Benz USA recalled 41,838 of its SUVs in the North American market in early 2021 due to a software error in its Electronic Stability Program, a feature that applies a twisting force to one of the car’s front wheels so that the car pulls itself towards the turning direction during sharp turns to maintain stability and comfort. Timely recall is especially important for software parts that are crucial to safety. In the mid-2010s, OEMs saw a drastic increase in the number of emergency recalls with regards to software flaws and errors, with the percentage of software-related recalls reaching 46% in 2016. Having more software means more software issues. For instance, ECUs are built into the powertrain to run features like advanced driver-assistance systems (ADAS) and to monitor turning angles and road conditions to allow for on-demand all-wheel drive and traction control. With more than a hundred electronic control units (ECU) equipped in an average car, almost every function is either controlled or monitored by software. This might have been the case a few decades ago, but a modern vehicle today contains many more software components than it seems. Many car owners tend to believe that software only exists in a car’s infotainment system and thus downplay the importance of software maintenance. ![]() The Software-Oriented Car: Skyrocketing Software Compliants and Recalls Such software updates are called Over-the-Air (OTA) Car Updates. ![]() But as cars become increasingly connected today, OEMs are trying a new approach by sending and installing software updates over the air (the Internet) to the cars directly-the same way that smartphones and computers receive updates. Traditionally, software updates are performed in person at service centers. Software updates are an integral part of the overall user experience as they contain important feature enhancements and crucial security patches. Just like how IT software and operating systems receive regular updates from their vendors, vehicles receive software updates from their manufacturers. ![]()
