2008 Prius DEFINITELY has a brake problem

I have a 2008 Prius with 25K miles and just put brand new Nokian tires on the car (as recommended by this site). The car does NOT brake after hitting bumps (washboard-like) in the road. Additionally, the car slips in the rain and snow ALL THE TIME and the immediately after that, I have no brakes. I agree with the person who said it 'feels like hydroplaning'. This is a REAL and SERIOUS issue. I am now very concerned about driving this car.
In fact, I am so concerned I am thinking about dumping the car.

 

one additional note.... Right before I lose my brakes, the yellow 'traction control' (slippery surface) light comes on then goes off.

 

see my next note...

 

If we get enough domestic US responses, do you think they will do anything about it? I need a place to vent!

 

I have had this problem since I bought the car (although it didn't seem as frequent in the beginning, but still happened). They told me that 'it is normal for the traction light to come on over rough surfaces'. I say BS.

 

I have had cars that had traction control in the past and never had this problem. If I brake HARD on a flat dry surface, I can feel the ABS kick-in. It only seems to be a problem with rough and slippery surfaces. After the traction light goes out, I still don't have braking for a few seconds - which is REALLY unnerving...

 

PriusLewis - thanks man. I definitely agree with you, and I also owe too much to sell this without pain. I am planning on buying a third car (maybe a Jeep w/ 4x4), so I know I have traction.

 

I thought this site was supposed to be a fair and unbaised discussion around our experiences with our own Prius cars. I started a thread because I saw several other people having similar experiences. If I am dealing with pompous, uncaring individuals, that only care how their site looks and not deal with real issues, then thanks, but no thanks. I think PriusLewis was on the money by saying there are mostly Toyotaphiles who are snobs on this site.

 

Thanks Qbee64. I did look at the other threads (although I missed a couple). But what I don't see is any real solution. There has to be a mechanic on this site who works with Prius that can definitively say that this is a computer problem related to the regenerative breaking. Also, if there is no solution (yet) for the 2008 issues, I am willing to contact Toyota HQ to discuss as I have some contacts that may be able to help.

There is now so much going on with the on-board computers (between controlling the brake lighting, Antilock capabilities, and now regenerative braking) that with the millions of lines of coded, there is potentally some bugs. In addition, the stiff frame does not appear to be the issue as this occurs on wet flat surfaces as well.

I do not want to cause issues on the site and if I should have posted under a separate thread, then so be it. I am not sure what constitues the creation of a separate thread though.

 

apologies - I meant Qbee42...
