Took it to dealership and they put it on their wonderful computer system, but couldn't find anything wrong, and when they drove it the problem didn't duplicate itself. Now I am driving it and scared that it will die in traffic. Definitely not going far from home.

Car was serviced 9-28-18 at the dealership for 2 problems with losing power while trying to accelerate. Today while accelerating, it felt as though the brake had engaged, instead of gaining speed the vehicle began to decelerate. At the same time a red warning light appeared on the dash that said electronic throttle needs to be serviced, accompanied with red lightning bolt type flashes. It makes me feel unsafe.
