2005 Toyota Prius Owner Comments

problem #1

Sep 302004

Prius 4-cyl

  • Automatic transmission
  • 100 miles


The shift-by-wire transmission selector in my 2005 Toyota Prius ignores my shift if I move the shift lever too quickly. This has almost led to several accidents. On my first day driving my Prius, I was parked in a diagonal, on-street space. My view of approaching traffic was blocked by the vehicle beside me. When I backed out far enough into the traffic lane, I realized that traffic was coming. I needed to move forward quickly to avoid getting hit. I quickly moved the shift lever to "D" and accelerated. The car lurched backwards instead of forwards. I hit the brake and quickly but carefully shifted to "D" again. Approaching traffic was now almost at my location. I accelerated again but the car lurched backwards, not forwards, again. The car had ignored both inputs from me and remained in reverse. Luckily the approaching traffic slowed to avoid crashing into me, giving me time to slowly and deliberately move the shift lever to "D." this time the car moved forward. I can easily shift the lever too quickly, which results in no gear change. Toyota said this dangerous condition is normal for the Prius. Also, there is a column-mounted stalk too close to the dash-mounted gear shift lever. It is easy to momentarily put your hand on the wrong stalk when trying to shift gears. Finally, the car loudly beeps whenever reverse is selected. This is inside, not outside I assume to let you know that you are in reverse. That loud, distracting interior beeper is a safety hazard. I was not aware of hearing it when I had the backing incidents described above but I am very aware of it when I am carefully backing up and trying to watch and listen for pedestrians, cars, etc. Behind me. My Toyota dealer told me that it cannot be disconnected. All drivers from owners to valets, expect the gears to change when they shift. The public should be warned about the Prius until Toyota makes a transmission fix such as retrofitting the cars with a conventional shift mechanism.
