Recall - Prius ECU brake update completed today

I got my 2010 brake ECU reflashed yesterday here in the USA, and noticed no difference. It was raining/snowing/sleeting here and was driving appropriately for the conditions so I can't say if I would notice under dry road conditions.

The brief reduction in brake force when braking lightly over uneven or slippery road conditions is not something either my wife or I notice too often, and we both thought it was at about the same levels as on our 2007 Prius (sadly wrecked by a deer last year) and absolutely nothing to be alarmed, or much concerned over as the car always would stop regardless. We just thought it's a slight quirk in how hybrid cars work, like the engine shutting off every now and then. If people insist it was more common on the 2010 I'll not argue, but we did not notice it to be so, albeit from our memory of the behavior of the 2007 version.

Rumple

 

I did notice the problem before and now feel the difference.
I agree totally that it feels more like a non hybrid car and waiting to see if it effects anything else like MPG. I think I'll do the same with reverse beep next time I service the car.

 

I don't have a 2010 mpg baseline to use for before vs after the brake campaign. I sort of hope Toyota hasn't gone and overcorrected the issue now. As for the reverse beep. I disabled it on my old 2007 Prius but have decided to leave it alone on the 2010 because I was sometimes ignoring to even look when I backed up--dangerous chances. Anyway, I realized that the beeping helps me focus more on my backing up use of the camera.

 

My Prius's reprogramming is planned on March 19th.
I will keep you informed of my felt.

I experienced the brake problem twice since purchasing my 2010 Prius. After getting the update, I drove over the same railroad tracks where I had the second experience and applied the brakes. The car acted normally. Since then I have tried to recreate the problem on several bumpy roads but as yet have been unable to.

As far as the feel of the brakes, I feel no difference when applying the brakes. Some here have posted that the brakes now feel different, but to me they feel exactly the same.

 

Got a letter from my dealer about the recall this week. My only incident with the brakes was just after I got the car and I attributed it to a slightly slippery road--didn't know about the "problem" at that time. After yesterday I really joined the ranks of those experiencing the braking "hesitation"--and know the first time was probably ice. I hit a pothole coming up to a stop on a freeway off ramp. Just kept pushing the brake and no problems and no panic. Sort of glad I found out what people were talking about! Will probably get it fixed in the next month. Now--have to find the thread where the "grabbing-brake-while-in-reverse syndrome is discussed. Had to shut off the car and restart to get backed out of a parking space yesterday. Not a good braking day!
