This car cuts off power to save the powertrain from damage, that is what toyota told me. You must be extremely careful when entering traffic because you can lose power for 2-3 seconds if the cars computer senses any wheel spin. The way i see it this is a machine that was designed by the engineers to save itself from damage, the safety of the driver is of no concern to the computer program. You must always!!! Be…

While driving a 2009 toyota prius at 50-55 mph on a single lane highway outside of prescott az, the drive system suddenly shut down and no response was felt when depressing the accelerator pedal. Lots of indicators came on and my wife was able to steer the car to the side of the road where there was just sufficient room for following traffic to go past. After spending a few minutes going through the owner's manual…

I was driving my 6-month old 2009 prius one summer day on a dry, paved, slightly downward incline when the following problem occurred. As i approached a traffic circle at about 5 mph and then applied the brakes, my car jumped forward for about a second and a gold light on the dash was briefly visible through my peripheral vision. Because i was familiar with anti-lock braking systems, i think that i kept my foot on…

Power Train · Traction Control System
Loss of engine power in 2009 toyota prius. When accelerating into traffic in wet or low traction conditions every time one of the front wheels looses traction, the engine abruptly goes to idle for 3 seconds and the car severely decelerates. Only by removing your foot completely from the gas pedal and reapplying throttle will the car start going again. This extreme over-reaction of the traction control system is very…

When putting the prius into park and shutting off the car, it rolls back every time. Putting on the emergency brake helps but it still rolls. Also putting the car into neutral (ie going through a automated car wash) the car does not stay in neutral, it pops out and is very hard to put back into neutral. *tr

2009 toyota goes forward when i put it in reverse. I apply brakes, try again, and it goes into reverse, sometimes after two tries. Toyota service here claims they can't reproduce this. I don't believe them. It doesn't do this every time, but most times. Afraid to parallel park. Have you heard this one? *tr
