#28 of 65 2006 Prius repeated loss of power at high speeds
Nov 13, 2007 (9:34 pm)
On 3 separate occasions in the past 6 months my wife's Prius has lost power while operating at high speeds in the commuter lane on the freeways in Southern California.It is amazing that she was not involved in an accident on any of these occasions.Each time, She had her car towed to a Toyota dealership.The warning signs all came on with each episode.The Toyota dealership has never told us that this has been a problem with Prius automobiles in 2004 and 2005.One dealer actually accused her of running out of gasoline and precipitating the power failure.We are disappointed in the way Toyota has handled this situation.They have not been honest with us.My wife is seriously considering going to arbitration with Toyota and getting a new car that she can drive with confidence.

From my experience, I've learned that "inconsistent" sensor inputs will cause the Prius control computer to shut down. Evidently the gas pedal sensor in my 2001 Prius was occasionally putting out a faulty signal, causing the shutdown, after which the car would struggle along on battery only. From an Internet board I learned that turning off the ignition, waiting, then turning the engine on again, three times, will "reboot" the computer. Indeed, that got me back running the last time this happened. (That also explains why, when the car was hauled back to Toyota, they found it running okay.)
A good technician at Toyota was able to identify the problem through the computer readouts. Since the gas-pedal sensor in my Prius was replaced, I've had no more of these on-the-road failures.

Several years ago, a dozen or so similar incidents were widely reported in the national press. All were traced back to a software problem that prevented the ICE from coming on due to a false faulty sensor that the software did not handle. With the ICE not coming on automatically, the big traction battery soon runs out and the car comes to a quick halt, most times in a fast traffic lane. I had heeded the TSB and had the software updated a few weeks before and have never suffered from that problem although your 2006 won't have that software problem, it might have another. More likely, it's one of the many sensors thats shutting down the ICE for some other reason.
#31 of 65 Battery Failure?

I read recently that sustained highway driving can result in the hybrid battery failure, causing the car to run on the gas engine only. The article claimed that deceleration and braking were necessary to recharge the battery. Is this true, or is this bogus??

"Several years ago, a dozen or so similar incidents were widely reported in the national press. "
It's been a while since this stuff was covered on the Forum, but IIRC there were around 50 unique complaints in the NTSB database on the problem. There were more reports than that, but some appeared to be duplicates.

That was an old software+sensor bug that has been fixed. Anyone who had the TSB applied could not have had the problem.
#35 of 65 It happened last night
May 07, 2008 (3:00 am)
The one night I didn't bring my cell phone to church!!! System failure on my 2005 Prius going about 65 mph on country highway. It slowed down in speed and I pulled over where I could. If there was an "update on the software" I was never notified. AAA came out and dropped it off to Toyota..on my way there this morning armed with the CNN article. What is this? I just made my last payment two days ago!!!! I had to walk in the dark for about 1.5 miles in heals before a neighbor passed...my fault on that!

May 6, 2008 at 8:50pm. AAA towed to Toyota and they started working on the car before they called me. It started up for them but with the engine light on. I got a free rotation and oil change out of that because no one called me until 8am when I was already on my way in. Anyway, the air filter was heavily dirty and after running a computer check, nothing else noted. I didn't fall within the "system" recall of 2005's so we'll see what happens. The dealership was great though I must admit. So many Prius's here and I'm the first with something odd to happen. I still love my car!!!!!!!!!!!!!!!!!
