Abs brake light comes on and beeps, and brakes become squishy on my 2003 toyota prius. Toyota dealer does not know what the problem is. I have spent hundreds of dollars on diagnostics, but the problem keeps happening. I have noticed similar complaints on the internet regarding this abs light problem, and squishy brake problem. Toyota dealer informs me that they have heard nothing of this problem from the toyota…

A number of times when i brake on uneven roads, the brakes on my 2003 prius feel as if they aren't working. They have always caught almost immediately, so that i haven't thought of reporting the problem until the recent reports on the newest prius model. Incident date is the most recent, even though the problem has been there since i bought the car. *tr

I have a 2003 toyota prius and also experienced the exact same braking problems as has been reported about the 2010 prius. If i go over a dip in the road while braking, occasionally the brake will not hold (even if it is fully depressed) and i need to release and depress again. I was told by the dealer that this was the antilock braking system and not a real problem with the car. I now suspect that it is the same…

I own a 2003 prius. When i bought it, before i ever drove it (was snow and ice) dealer told me to be careful of the brakes. He said, when applied, it may feel for a split second that i was speeding up or not stopping. The car does this on slippery and rough rd and always has. I thought that was the nature of the hybrid and have learned to drive accordingly but it is definitely a trying situation. *tr

In reading recent media reports regarding braking failures of the 2010 toyota prius, i realized that i have experienced similar lapses in my 2003 prius' braking since the day i bought the car. I wanted to get this on record as it seems the media reports believe this to only be a problem in the 2010 model when this may be an issue that has been going on for a long time. Basically, whether or not the phenomenon occurs…

I hope you are not limiting your investigation of prius brakes to the 2010 model. I have had the same problem on my 2003 prius since the day i drove it home. When going over uneven surfaces, particularly metal plates or manhole covers, braking momentarily stops and does not resume until the wheels hit the regular road surface. Although i have had no accidents, the sensation of skidding is frightening. *tr
