Chevy Blazer Troubles Add to GM’s EV Growing Pains

As one of the nation’s first owners of General Motors’ new electric Chevrolet Blazer, James Hattin was loving the SUV—before the problems began.

On a trip from the mountains back to his home in Burbank, Calif., he and his wife heard weird clicking noises coming from the dashboard. A short time later, the cruise control went out. A few days after that, in his driveway, the car’s screens went blank and the car wouldn’t start.
