Remember when our parents threatened to stop the car right now in the middle of the highway if we didn't simmer down in the back seat? Yeah, the driver assistance system in the 2014 Chevy Impala is kind of like that, but actually acts on it. A 2014 Impala owner is a bit shaken after his car came to multiple screeching halts without ever touching the brakes.
The worst occurrence was when the car went from 40mph-to-zilch an an instant, making this owner look more like a Hollywood stunt driver than a daily commuter.
Right before stopping, the car allegedly sounded three or four beeps from the forward collision avoidance system. NHTSA said they will also look at the 2013 Cadillac ATS as well because it uses the same driver assistance system -- a system that apparently isn't a fan of Newton's first law of motion.
Interestingly, NHTSA decided to open this investigation after a single complaint. Perhaps that's because they recently took heat for ignorning issues about GM's faulty ignitions and defective power steering problems.
It's still early; if the investigation advances or leads to a recall, we'll let you know about it.
