I noticed a strange rattling noise from the engine when starting my car 1st thing in the morning and when starting it after it has sat for a few hours; I researched online for other similar complaints and found that Toyota has discovered an issue with the cam shaft on some vehicles. I have just learned of a 2nd recall on my vehicle, this one for the rear suspension after visiting the Toyota website, but I found nothing about a recall regarding the cam shaft. I had planned on bringing the cam shaft issue to the attention of the service tech when I take the vehicle in for the rear suspension recall but am unsure if anything will be done. Please advise.

While stopped at red light with right foot on brake, engine suddenly accelerated to very high RPM. Shifted to neutral and engine revved even higher. Turned off ignition. Signal turned green and since I was in traffic, decided to try to start engine again. Engine started and performed normally. Immediately drove to Toyota dealer who said they could find nothing wrong. We are now afraid to drive this vehicle! things could have been much worse had we been moving in traffic!

I was coming to a stop at traffic light. As I slowed down with my foot on the brake the engine suddenly began to surge. Since my foot was already on the brake I was able to push down harder on it to stop it from hitting the car ahead of me. Within a second or two, as the engine continued to surge, I shifted the transmission into park. When I did this the engine surged even more. I then turned off the engine by turning the key which did shut everything down. I then restarted the engine and it ran normally. I was somewhat shaken up by the incident. Note that this had nothing to do with the floor mats or hitting the wrong pedal. My foot was on the brake pedal the whole time the incident occurred-if it hadn't been I would have crashed into the car in front of me.

While driving 25 mph, I started to brake for a light. The car suddenly accelerated and it took both feet applied to the brakes to stop and avoid hitting the car in front of me. Ten minutes later, another sudden acceleration occurred, followed in rapid succession by a third acceleration.
