Twice within a month, while traveling at 70mph, my vehicle suddenly and quickly slowed to approx 20mph all on its own, with traction control and engine warning lights turning on. Vehicle would not accelerate and stayed at 20 mph. Ability to steer and brake was hampered, but on both occasions I was lucky enough to be able to ease over to the shoulder without being hit or hitting anyone else. Both times the car was taken to the dealer for repair, but because the dealer could not recreate the problem, the only remedy done was to clean the connections to the traction control module. It is sheer luck that no one was hit or injured.
