I also had a braking problem with my 2006 Toyota Highlander Hybrid, where I coasted into the car in front of me because I was travelling under 20 mph and the ABS brakes never "grabbed" during an emergency stop. I filed a complaint with the government agency the National Highway and Transportation Safety Administration at http://www-odi.nhtsa.dot.gov/. If enough people file complaints there, they will open an investigation for a possible recall. The Consumer Affairs website is useful for lawyers to find class action lawsuits, which would be nice to recover all of the money that people are spending on these rear-end and slow speed accidents. I also alerted Consumer Reports, as they always rate these cars very highly, which is misleading.

One has to be extremely careful.
So far, most HH owners have reported a "slip" or "gap" in braking at low temperature but few, if any, have reported incidents that resulted in a "run away" condition as you have reported. So I will caution against generalizing this to be something that has been reported "all over" the web.
I have heard of ABS incorrectly activating at very low speed (Chevy?) when it ought to shut off. ABS activation at low speed causes the brakes to not fully engage so the car keeps on rolling. Low speed rolling though should not send a car across so many lanes plowing onto curbs. So something is definitely wrong with your vehicle.
Unfortunately, the recent "gas pedal" run-away problem that resulted in deaths have shown that Toyota will also hide the truth and refuse to acknowledge safety concerns. It continues to blame the matt instead of looking into the accelerator system. Anyway, do be careful how you make the claim.
All that said, I am losing confidence in Toyota's reputation. Having a defect is one thing but refusal to own up to the problem and fix it is much worse. Time to look at Ford again.

Not sure what this means. You need to be very careful and not confused the problem. Is this inappropriate ABS activation at low speed causing car not to stop? Certain Chevy trucks of a particular model year had this problem.
By not grabbing, do you mean the brakes did not work? Or did you cause the car to lock up and skid because ABS did not work?
The manual states that ABS will not activate under 25-MPH. This is not new and is actually a requirement of ABS systems. ABS is supposed to shut off at low speed else it will keep the brakes pumping and not able to stop your car. This is a totally different problem that the ones we have been reporting? Is this what you are experiencing?
#73 of 139 Hi Hy Brake issues
Feb 03, 2010 (7:12 am)
I have a 2006 Hi Hy Limited that I bought pre certified in 2008 with 38K on it. First let me say I LOVE THIS CAR!! I would buy it again in a second!! I have experienced the brake "coasting" slightly when I step on it lightly but I believe this to be less a defect and more of an after effect of the regen brakes. You simply have to learn to brake differently? The brakes are drive by wire as is the gas pedal. NO LINKAGE!! This is a radically different driving concept and you really need to treat it as such. I've always tried to follow other cars at a safe distance and when the coasting effect does occur, simply pressing the brakes slightly harder corrects this and stops the car on a dime!! I am amazed at how well this car does stop!! Follow at a safe distance proportionate to your speed!!! This more then your Hi Hy's brakes is probably the bigger problem?? Hope this helps???

Not Applicable. My brakes work properly as long as i don't hit a bump in the road. Let's say I am slowing down from 25 mph. The dial on the left (mine is an Rx400h) show regeneration, i.e. it is below the neutral zone. Then, I hit a small bump, an irregularity in the road surface. It doesn't take much. The braking power is reduced and the dial shows that regeneration has stopped. Regen, doesn't come back unless i stop braking momentarily.. If I stop and reapply the brakes, the dial shows regeneration again and the braking power returns to normal.
This could be a loose connection. The dealer says he never of heard of this problem. But, it could also be a bug in the ABS or stability control systems.. That is, the small bump could stop wheel rotation which is sensed by both of these systems.
Thanks for trying to help...
#75 of 139 Will recall affect HH?
Feb 03, 2010 (5:09 pm)
Seeing the news today about the Prius braking problem coming to light, it sounds all the world like what we've been describing on this thread with our HH's.
Wonder when HH's will finally be recalled to address the braking gap problem.
#76 of 139 Here's the latest from Toyota
Feb 03, 2010 (5:13 pm)
Hot off the presses Feb. 3, 2010, from Toyota:
Statement Regarding 2010 Model Year Toyota Prius Inconsistent Brake Feeling
In certain 2010 model year Prius vehicles, Toyota has received reports that some customers have experienced inconsistent brake feel when the vehicle is driven over potholes, bumps or slippery road surfaces.
Toyota is currently in the process of confirming these reports and investigating the vehicle driving conditions under which the reported phenomenon occurs. It would be premature to comment until the investigation has been completed.

I have to agree with this comment. When you have been mentally calculating your stopping point while gently breaking and hit a small bump in the HH you suddenly discover your mental calculation was wrong. This isn't some sort of expressway experience. The comments about "traveling too close" demonstrate that there is a lack of understanding about the problem being described by some of us who have experienced the sudden change in braking friction after the bump. It's the unexpected transition from regen to hydraulic. This is NOT normal or something we just need to get used to. The denial by certain reps is cover. I talked to a Toyota mechanic just yesterday - having the car serviced - and he knew exactly what I was talking about and admitted the problem exists. Now Prius Hybrids are being examined for brake problems. I have enjoyed this vehicle - but am very frustrated with Toyota's response of "plausible deniability". Why did they wait until a family was killed with a proven gas pedal irregularity before taking action. Chances are these brake problem will only cause a slight bumper crunch for those who have learned to anticipate it - but someone is going to be mortified when they didn't stop in time for the pedestrian at the mall when the brake transition fooled them into stopping a further distance than intended.
#78 of 139 new today; prius brakes had problem in braking
Feb 04, 2010 (6:10 am)
Today Toyota released info. that they had fixed a problem in Prius where the gap in braking was noticeable. They did not do a recall, but said it was a programming problem they corrected in models designed after January. It's disapointing that it wasn't made public before now, but I would guess that many companies do this.
We just sold a Mazda CX9 with multiple problems, none of them recalled or discussed by the company, even though service knew them to be recurring problems. We bought a 10 HiHy fully loaded except DVD at invoice plus $200 for color (only amethyst pearl equipped this way in California) but discounted XM install $400, so all good. We feel very confident with Toyota and were happy to get the discount, as he had been quoted $1500 and $700 xm install over invoice at the beginning of the month. Good luck with brakes, ours seem ok but will take to the dealer if a problem comes up.

I have the same car with the same problem. But it happens to me even more than bumpy roads. It happens all the time without warning or explainable reason (braking from high speeds, low speeds, smooth roads, bumpy roads, cold started vehicle, warm started....) This just happens all the time. I have been to 2 dealership and can't "recreate the problem" because they take it on a 1 mile loop, hook it up to a machine and say it didn't read any bad codes. I made a formal complaint with the NHTSA today and suggest everyone does. There is more of a chance they listen now than ever. I am taking back to another deal again on Tuesday after hearing about the prius problem.
I will give an update on Tuesday. In the meantime, everyone who owns a Toyota/Lexus hybrid, start your complaint. There is a safety problem with these cars. It is the best way to save us all money and maybe a life.
P.S. If your gas pedal sticks, PUT IT IN NEUTRAL!
