Dynacraft said the toys pose a fall hazard because they can quickly, unexpectedly accelerate.
Dynacraft is recalling the battery-operated Hot Wheels branded toys.
They were sold in green and black (Model Nos. 8801-05 and 8801-05com) or red and black (Model No. 8801-15). Dynacraft said both models have the Hot Wheels logo on them.
