Prius 4-cyl

  • 650 miles


Emergency braking delay in brake action. When the vehicle ahead of me immediately hard-braked on a yellow stop light at a "red light" camera monitored intersection (westbound Illinois 38 at summit in villa park, il) I had to brake hard and maneuver to avoid rear-ending him. This was the first, and only, emergency stop situation I have had with my 2010 Toyota Prius. We were travelling just a bit below the posted 35 mph limit, and I was following at an appropriate interval (3+ seconds or about 3 car lengths). There was about a 1 second delay between jamming on the brake and significant braking action. I never experienced such a delay in my ABS equipped 2000 Chevrolet Monte Carlo ss or my 1995 Ford Windstar LX, since this experience I drive the Prius with a greater interval, although this means other drivers regularly merge into the "safety" gap that I am trying to provide.

2010 Prius brake applied in zero temperature weather approaching a red light on slight down sloping road covered in ice/snow. The brake pedal was pushed as would normally be applied (maybe approx 1/3 - 1/2 brake pedal travel) and there was no applied braking. The car kept rolling forward to where I had to make a decision to continue rolling with a right turn into the intersection and continue travel. Luckily the oncoming traffic was far enough away to not crash into me. I would estimate that the brake was applied for about 1-2 seconds, enough travel time to force me to make a decision that I needed to continue through the intersection before the oncoming traffic. This same type of scenario occurred on an exit off of an interstate ramp down another down slope with ice/snow that again when the brakes where applied, the regenerative engine brake applied, but when the ABS went to engage due to the slippery surface, there was a 1-2 second duration of sensation of no brakes. Pushing pedal further (or just waiting the 1-2 second delay) seemed to eventually apply brakes. I am a systems/test engineer that performs numerous work on commercial and military aircraft and I now know how to anticipate this situation for myself (I.e., I am more careful on braking earlier especially on slippery surfaces more than normal distance from my other Honda vehicles on same type of surfaces to account for this possible 1-2 delay time in braking); however, this is unacceptable for my wife who does not have the same experience as I do or same technical feeling of what this vehicle is doing. Again, if the traffic on that one intersection was closer to me than it was, there would have been a side impact collision. I have yet to experience this issue on solid roads over bumpy surfaces. With today's Toyota revelation that the Jan 2010 Prius has a fix for this, I demand to have this same fix applied to my three month old 2010 Prius.

I was driving my 2010 Toyota Prius down the road here in berkeley, ca, and applied the brakes as I was hitting a bump in the road. The brakes did not work. I thereafter lifted my foot off the brake and hit them again, at which point the brakes worked correctly.

I want to report a momentary brake failure of 2010 Prius over uneven roads 2 months ago. I didn't report it earlier because I didn't know if it was a one-off or systematic issue. Two months ago, I was driving a newly owned Prius with hardly 4000 miles on it over a stretch of rt. 93 from andover to boston. I was traveling at about 65 - 70 mph on the left fastest lane. I cam across a bumpy patch, probably the road was being repaired, and it was not late for me to slow down as I didn't expect such unevenness on a major highway. I stepped on the brake while the car was being tossed up and down by the bumps and I immediately felt that the car lost braking. Luckily, there was no car ahead of me and the braking did recover after the car settled down. I owned 4 Toyota's from SUV to the hybrid and Prius is the only one that has this problem. I just want to support other people's complaints about this car. I must say that the braking did recover quickly that a collision was not likely unless someone drive the car very fast on an uneven road that is also crowded. However, a car should not behave like this under any conditions.

I have a 2010 Prius that "lurches" when I brake. This only happens every once and a while. I took it to the Toyota dealership, they looked it over and said it was fine. To say the least I continue to be very concerned.

Prius 2010 slow braking. I thought it was just me but now I found out the braking is rather slow and a lot of others feel the same way. I have to adjust my braking when I switch cars with my wife and have to extra careful when I switch back to Prius.

I have a 2010 Prius and had a 2005 Prius with all the safety features. When I had the 2005 Prius, I noticed on some roads that during braking, the brakes would release then reengage, giving the sensation that the car is accelerating. This happens when the road has a series of dips (washboard). The first couple times this happened, it was rather frightening because the car in front of me had stopped, and I felt as if I were accelerating. This is a reproducible event that occurs at a known location that I simply avoid. The road in this particular area is also down slope, which lends to the acceleration feeling. I have driven my 2010 Prius over this same area with very much the same result. My initial assessment was that the traction control took over to regain traction, however I would not thing this is acceptable. The Toyota dealership said this is normal behavior and is not a problem. Please feel free to contact me and I can describe better the conditions for this very reproducible event.

I've been monitoring the Toyota recall news because I have experienced similar braking issues with my new 2010 Prius. The best way I can describe it is as if the braking system "hiccups" when the brake is applied while traveling over an uneven road surface. As this was a new vehicle type that I had never driven before I thought it was inherent.

We have been experiencing, intermittently, the exact problem described in recent news accounts about the momentary failure of anti-lock brakes on the 2010 Toyota Prius. When braking on a rough or slick surface, such as thermoplastic lane or crosswalk markings, the car feels like it's surging forward. We believe it is not so much an actual surging as it is the momentary absence of loss of braking, but it feels like the car is a bit out of control, and potentially dangerous. We have experienced this momentary brake failure on perhaps a couple dozen occasions. Fortunately, none of these incidents have resulted in a crash. We contacted the dealership to let them know that we had been experiencing the same issue described in news reports, and were told that they have not yet received instructions from Toyota about a recall or potential fix.

When braking at lower speeds and traveling over a transition (manhole cover, pavement break), the car will act as though the brakes lose grip for a second, then regain stopping power. I haven't hit anything, but it's been unsettling.

2010 Toyota Prius purchased April 2009. Reported to dealer shortly after purchase that antilock brake system releases brakes and lunges car forward if tires encounter uneven surface (e.g., pothole) while braking. Occurrence has resulted in missing stop signs, but no accident to date. Toyota dealership reported that this was normal operation despite my calling the dealership on two separate occasions.

The contact owns a 2010 Toyota Prius. While driving at speeds of less than 20 mph in overcast weather conditions and approaching a stop sign at a busy intersection, the brakes failed to engage and the vehicle proceeded with caution through the intersection. The dealer was contacted and stated that they never heard of any similar failures. There were no recalls or repairs made to the vehicle. The failure and current mileages were 1,400. Updated 03/18/10 updated 05/12/10.

I own a 2010 Toyota Prius and have experienced several times the braking failure problems recently discussed in the national media on snow and ice and on rough road surfaces. This has happened several times during the winter weather season particularly on snow and ice. I purchased my Prius in July 2009.

2010 Toyota Prius II--purchased August 2009. On January 23, 2010 I crashed my vehicle into a car that had stopped in front of me. I applied the brakes but was unable to stop the car before it hit the car in front of me. I am contacting you because I believe the brake issues with the 2010 Prius may have been a contributing factor in the crash. In the 5 months that I owned the car I remarked that the brakes did not seem to function like ABS brakes on other cars that I had driven. I chalked it up to the fact that car was new to me and had many features that were different from a traditional car.
