My Toyota Sienna 2000 might has an ABS system malfunction and caused a minor accident on Aug 28 2007 at 3:30 pm. The weather ~90C and sunny. I drove in school zone at the time the school over and the students presented on the sidewalk. I drove ~20-25 mph or less. The distance between my van and the car in front of me ~ 2 cars space. The car in front of me stopped suddenly because of one car in front of us turned left or made a U turn without warning. I stepped on my brake pedal very hard but the van still cruised like the brake was doing anything and I hit to the rear end of the car in front of me. My car have 133,000 mile on it. I had my front brake replaced by dealer when it 100,000 mile, the same time they replaced the timing bell, they told me the rear brake were in good condition at that time so I didn't had it replaced. Till now, I still have not heard any noise from my brake, no warning indicator light, and it has been always reacting correctly everytime I stepped on the brake paddle until the day my car involved into the accident. I plan after fixing the body of my van, I will send it to Toyota dealer for a break and ABS system check or inspection. I have a neighbor also have a Toyota Sienna 1999 van and he told me that he also involved in accident last year at the low speed and the ABS system didn't work also. And he brought it to the dealer for inspection, they found nothing wrong and his van had not failed again. I hope if there is problem of Toyota Sienna brake or ABS system, your Agency will investigate and notify us so we can avoid any accident related in the future. I will report the same thing to the dealers service department when I bring my van in for repair. Thanks for your help.

ABS pump motor failure. Almost lost control on wet surface. ABS panel light was on since Aug. 20006, Toyota dealer inspection stated code #14,51 (ABS pump motor failure) it is unusual but not cover by warranty.

2000 Toyota Sienna with approx. 64,000 miles: Antilock brake system (ABS) computer failed. Dealer said replacement cost would be $2000 and blamed failure on "dirty brake fluid" which seems extremely unlikely since vehicle was purchased as a certified used vehicle at 36,000 miles less than 2 years prior to failure. Failed ABS computer is still installed on vehicle since we cannot afford to replace it.

At approximately 40,000 miles anti-lock brake warning light started turning off and on. Eventually ABS light stayed on and the ABS system stopped functioning. The ABS system has not been repaired due to the very high cost of the ABS actuator part. The lack of a functioning ABS system makes the car unsafe in situations where the anti-lock braking feature is needed (such as wet roads).

I took my 2000 Toyota Sienna into a dealer because the "ABS" light went on approximately 2-3 days ago. Although phoenix has had a wet winter, there has been no significant rain for a number of days. The dealer said the ABS "ECU" was "dripping wet" and the ABS computer was "fried". the cost to replace with materials and labor was $1,800. Do these units typically fail" why would the ECU be so exposed to the elements as to make it "dripping wet"" he did not identify any defect in any protective cover (if there is such a thing).

I bought this 2000 Sienna new. I have had three major problems in two years. The latest failure is on transmission. Toyota replaced it with a rebuilt and it is giving me all sorts of problems that Toyota is refusing to acknowledge and unwilling to replace the substandard transmission with a new part. The transmission is noisey. I have experienced slips in gears, hesitation in shifting, underpower when accelerating beyond 60-65 mph or driving on hills. I have difficulties changing in and out of fast lanes, it is dangeours and Toyota insisted that it meets the standard. The same arrogance that they have displayed when I presented them with the power door porblem. Now they revealed to me that they acknowledged the door problem but why aren't them issuing a recall. There was also problem with the antilock brakes. I nned you assistance to resolve my transmission problem as well as bring the safety issue on Sienna to the public awareness!

Location-parking lot, raining, tires lost traction and accelerator stuck on full, brakes would not function. The vehicle propelled forward glancing off the back of a full sized pickup and deflected into a Suburban where it finally stopped. No one was hurt but this situation could have been very serious if anyone had been near because I had very little control(steering only).

Intermittently when the brakes are applied the pedal went to the floor, resulting in extended stopping distance. The dealer has inspected and repaired the vehicle several times.
