unintended acceleration

On 1/11/2016, on Route 1 S College Park, MD, the weather was clear and the road was dry, at around 1 PM, as my husband was slowing down at an intersection, the Honda suddenly accelerated hard and he nearly hit the car in front of him, but he managed to put it in park and it stopped. He took it back to Priority Toyota and their diagnostic machine said there was no problem with the vehicle. Believing their assurance, he kept driving the vehicle, then the same sudden acceleration happened again on Wed 1/13/2016 and it happened twice on 1/14/2016. So he did return the vehicle to the dealership and the Sales Manager gave him a 2012 RAV4. Less than an hour later, when he slowed down to exit from 395 S in Arlington, VA he experienced a hard acceleration and slammed hard on the emergency brake to override it. Then 2-3 miles later, the hard acceleration reoccurred. He then overrode it again by slamming on the emergency brake. Then the battery died and he was stuck in traffic at 6:30 PM. That was the first time in 50 years of driving different vehicles that he was ever stuck in traffic. Unbelievably, Carfax never reported any prior problems with this vehicle's history in its reports.

Just five days after I experienced acceleration during braking I had the same occurrence on the road in heavy traffic while releasing my foot from the brake the car accelerated causing me to reapply the brakes to avoid striking the car in front. My wife experienced this firsthand and fully understood what had happened to me just five days earlier, albeit under different circumstances (parking). Do I have a lemon or are other people experiencing the same thing. The dealer did not want to talk about it because he said Toyota's instructions about such incidents are to contact the company directly. The only problem I had today was that the number they provided was Toyota Financial Services and not corporate complaints. We'll see how it goes tomorrow.

My 2012 Rav 4 has done this from the day I bought it. Periodically, it accelerates while braking for 1/4 to 1/2 second. It is serious when you are going 55, come to a stop at a red light with someone in front of you. Sometimes I have to use 2 feet to brake. The acceleration comes miliseconds after the transmission downshifts. Mostly noticable when it shifts down to first or second gear. There will eventually be a recall on this. I almost rear ended another car at a stop light. The acceleration feels like you are pushing the brake and accelerator at the same time. Problem is, it only does it about once every ten times. It doesn't happen all the time.
