I bought an '09 Tacoma 4x4 on April 4, 2009. Since that day my transmission is slipping, especially when trying to accelerate coming out of a turn. Rpms bounce around and sometimes it get stuck in a gear or revs like its in neutral. I have almost been hit twice from behind because the truck doesn't accelerate. This is a real problem and a safety issue. When I talked to the dealer they admitted it was happening but that it was "normal" due to new technology with computers. When I did some research it seems that lots of others are having the same problem and Toyota isn't doing anything about it. Someone is going to get hurt-there will be an accident because of this.
The contact owns a 2009 Toyota Tacoma. While accelerating, the vehicle acts as if it is stuck in neutral. Afterwards, the rpms slightly increase accompanied with sudden screeching noises. The contact took the vehicle to the dealer and they replaced the computer module. Soon after the repair, the failure recurred. He is in the process of taking the vehicle back to the dealer to have it inspected, and is currently waiting for a response from the manufacturer. The failure mileage was 400 and current mileage was 700.
