NHTSA recall 16V272000

What's wrong: The memory chip in the electronic brake control module (ebcm) may fail and cause the loss of electronically controlled brake systems including anti-lock brakes (ABS) and electronic stability control (esc). As such, these vehicles fail to conform to Federal Motor Vehicle Safety Standard (fmvss) number 126, "electronic stability control systems."

Why it matters: If the ebcm fails the primary braking system will still function, however, the loss of ABS and esc increase the risk of a crash.

The fix: Gm will notify owners, and dealers will install a replacement ebcm, free of charge. The recall began on June 17, 2016.
