Liability for Software Defects

We live in an age of "smart products" with software powering our cars and medical devices and even financial systems.  This software enables cloud computing and Internet of Things (IoT) devices, self-driving vehicles and robotics, smart grids/roads/cities, and much more.  Unfortunately, software does not always work reliably and software defects can cause substantial physical or financial harm.

When an electronic system malfunctions, forensic analysis and a thorough review of the design of the electronics and software can be useful to identify the root cause of the mishap.  Barr Group's consulting and testifying expert witnesses routinely assist plaintiffs and defendants in personal injury torts and other litigation relating to software failures and defects.

Barr Group's experience with class actions is extensive and includes source code analysis and testimony in the runaway Toyota economic loss and personal injury cases as well as in suits relating to excess VW diesel emissions, faulty MyFord Touch subsystems, and deadly GM ignition switches.

Case Study: Runaway Toyotas

In support of automotive product liability lawsuits and a class action against Toyota, a team of Barr Group automotive software experts performed an extensive source code review of the engine control unit software for seven Toyota and Lexus models spanning the 2002 to 2010 model years. In analyzing these millions of lines of automotive software source code, the Barr Group team built upon a prior NASA review and concluded they'd found what NASA's engineers sought: “a systematic software malfunction in the Main CPU."
