2011 Toyota Tacoma. Consumer writes in regards to problems with the transmission and security system in vehicle.. the consumer stated one day as she was leaving work, the vehicle would not start. It seemed as though the vehicle didn't recognize the key and she was unsuccessful at jump starting it. The vehicle was towed to the dealer and the problem was determined to be with the security system, which had been installed and had not been removed completely. She also stated the automatic transmission was not shifting correctly, particularly when shifting up hills, it required her to forceful apply the accelerator pedal to get the vehicle to go appropriately. Again, she took the vehicle to the dealer, but the computer stated there was nothing wrong. The problem seemed to be getting worse, when in early December the consumer was in route over a double lane road over a mountain, when the truck suddenly felt as though it had slipped out of gear, there was no power to the drive train and there was a grinding sensation from the gas pedal. The consumer was able to pull over to the side of the road, put the vehicle in park, then drive and proceeded again. A similar event occurred as she made her way back over the mountain at the end of the day. However, the vehicle lost power again and it did not respond to the accelerator pedal, but it also made a very fast clicking sound. The consumer went back to the dealer, only to be told there was nothing wrong. The mechanic decided to test drive the vehicle and noted the vehicle seemed to be sluggish in the automatic drive position, but seemed to function more responsively in the 4th position.
