With laser cruise control on, vehicle will suddenly slam on the brakes and release with no other vehicles in front of it. This has happened 8 or 9 times in the time I have owned the truck. I have taken it back to the dealer 4 times for this problem, only to be told that they cannot duplicate it and nothing was done to repair the problem. The next day I received a recall notice to bring the truck to Toyota to repair a front sensor for this problem. I brought the truck in to the dealer and they said that water was getting into the front grill sensor and they glued a piece of rubber/foam over the sensor. A few days later the same thing happened again. My wife and I are afraid to even drive the truck and Toyota has said everything is ok. The second problem is with laser cruise on and set at 75 miles an hour traveling up a grade, the vehicle will downshift into third gear running the tach to 300 rpm's over the redline. Toyota says that this is fine and the truck has a governer to keep the truck from over revving 300 rpm's above redline at 5800 rpm. I explained that in the owners manual it says to never run the engine to redline. Again Toyota says this is normal and that they will not fix the problem. Redline is 5500 rpm.
