But, unfortunately, ECU failures are more common than you think, and they can be a costly problem to fix. In this post, we'll explore the warning signs of an ECU failure and why it's essential to address the issue promptly.

The Consequences of ECU Failure

An ECU failure can cause a range of issues, from poor fuel efficiency to engine misfires. If left unchecked, it can lead to more severe problems, such as decreased engine performance, increased emissions, and even complete engine failure. Moreover, ECU failures can also trigger costly repairs, including replacing the entire engine or transmission.
