When it happens

Too few of these reports state a mileage to give a range.

What owners wrote

“I was approaching an exit on the highway going about 60 mph when my car braked suddenly causing rapid deceleration. I was not touching the brake pedal and in fact tried to push the accelerator to no effect. Only lasted a few seconds but very frightening as there were cars behind me also driving at that speed.”

“I was driving past a school zone at 20 mph, came to a stop to allow children to cross street, as I began my acceleration past the school crossing, I reached a 20mph speed again and my CRV activated the emergency braking system without having anything in front of me that could have activated the forward collision braking system. Luckily I was not rear ended.”

“Driving down Piedmont Road in Atlanta on an overcast morning with no pedestrians, obstructions or vehicles in front of the car, the collision avoidance and braking system engaged for no reason and almost caused the car behind mine to run into me.”

“The forward collision warning and braking has activated a couple of times without any car front of me for a wide distance or when everything is all clear. It also happened a couple of times when turning a curve or exiiting, also without any car in front of me. The only thing I could notice was the dashboard flashing but I could not read it because I had to focus on the road.”
