This vehicle with an automatic transmission, by design, as I have been told by a Toyota technician, will not upshift until the vehicle has warmed completely. This is not only a hazard in traffic and is torture on the engine, but it is a hazard when one needs to use this vehicle in an emergency situation. For instance some one needs to be transported to the hospital immediately. With this vehicle you are required to wait until it warms up before one is able to transport. There are many other situations which could be presented, but I am sure that anyone who reads this document wi8ll understand the issue. Toyota needs to recall and design the vehicle to change gears if the computer determines that the driver is determined to drive the vehicle contrary to its programmed drive pattern. I notice that the document cl-10283172-6703 has proclaimed the same problem. As reported there, the colder the temperature the longer it takes for the vehicle to warm up. This warm up period is much longer than the average warming time for a vehicle. This is a critical issue for this vehicle and any others that have the same warming requirements. If one was required to drive the vehicle in a manner inconsistent with its prescribed procedures, it appears that a blown engine would probably be the result. This is not good because Toyota would not warranty the problem although they caused. Thank you for you consideration of this issue.
