Exerpt from the Detroit Free Press article on it...
"Death wobble is a term that sounds dramatic, but it is not known to have led to any deaths. A spokesman for Fiat Chrysler Automobiles, which owns the Jeep brand, references the term “steering system vibration” when answering queries about it."
I'll give them that "steering system vibration" sounds better than deathwobble but it's not going to change the headline!
