problem #12

Nov 112015


  • 105,000 miles


This afternoon I entered the highway and was going about 60-65 mph when my car suddenly started accelerating on its own, I repeatedly depressed the brake, even standing on it in an attempt to slow the car. The car was making a revving sound and the brakes were doing nothing to slow the car, it just kept accelerating. Finally, the brakes seemed to engage, the revving stopped, and the car seemed normal again. I pulled off the highway and called aaa to have the car towed to mechanic. Car has about 105,000 miles on it and it's been very reliable up until now. I will report to Toyota and I will not drive this car again, much less let my children ride in it.

The car's vehicle stability control (vsc) will activate unexpectedly, braking hard and causing temporary loss of control. There is also an audible alarm and the vsc light turns on. Occurs intermittently when driving between 30-50 mph, typically on a gentle curve like a freeway interchange. Has occurred as many as 9 times on a single drive, and has caused a couple near accidents. An internet search of online forums shows that this issue is common in Siennas after 100,000 miles. Thus far my Toyota dealer has claimed they are unable to reproduce the problem.

Driving various speeds, up hill or down and into corners especially the traction control or stability control system would engage the brakes and cut engine power, alarm beeping. Happened several times over a one hour trip. Streering would pull to the right. Driving conditions were such that the system should not have engaged at all. Dry, warm, newer tires driving recommended speeds for the road. All drivers on the road were at risk with the sudden breaking and steering pulling into another lane.

I was driving my Toyota Sienna 2006 today morning and the driver in front of me abruptly stopped. I was maintaining a safe distance and immediately hit my brakes. Although the brakes seemed to engage, the car accelerated and very badly rear-ended the car in front me. Has this happened to anyone before with the car auto-accelerating on it's own?

On March 13, 2015 driving on I-95 South in a 2006 Toyota Sienna van the cruise control would not disengage when the brakes were applied approaching an exit ramp. The vehicle would not slowdown in spite of pressing the brake pedal as hard as possible. Moving the control lever forward to disengage the function was also not successful. The exit ramp was inclined so the cruise control accelerated the engine in an attempt to maintain our speed at 70 mph. The vehicle went thru a stop sign, bounced off the guard rail and came to a sudden stop with the engine not running. The impact destroyed the right side of the vehicle and the stopping was so abrupt that the cell phone (in my shirt pocket)flew out ripping the pocket off the shirt. Neither the front nor the side air bags were deployed. Skid marks made by the vehicleż's right front tire (and possibly the rear right tire) prior to and after hitting the guard rail indicate the brakes were working on at least this side. Skid marks attributable to the left hand tires were not noticed.

ABS light and brake lights are on. Take the vehicle to a mechanic and they said that it is not the first Sienna with that problem and when both lights are on, the ABS system is disabled.

While driving in a residential area, going 5-10 mph, the anti-lock brake light came on flashing and beeping loudly. The steering system locked up and lasted 45 seconds to 1 minute. It would occur on a highway as well, no reason, ground completely dry. It would occur driving into the pa turnpike toll booth, rounding corners, going straight on 65 mph highway, (it occurred intermittently 60-70 times). The dealer (North hills Toyota 7401 mcknight road, pittsburgh, pa 15237 412-318-3000 were unable to fix it after I took it in twice. The last time, they disconnected the antilock brake system to fix the problem. I currently am driving with the system unconnected.

The car was sent to the dealer for timing belt kit replacement, upon inspection the technician found the anti lock brake system is malfunctioning due to the fact the above mentioned part, part # 44050-08030, the anti lock brakes hydraulic unit, is damage or inoperable. The technician told me this is not the first time he has encountered this situation in the same model/year of my car, but because Toyota has not pronounce on this matter there is little he can do about it except for replace the part which cost about $1,680, he advise me to inform the proper authorities for further investigation on why the part malfunction.

The contact owns a 2006 Toyota Sienna. The contact stated while driving approximately 5 mph the anti skid break light illuminated and the vehicle made a loud beeping sound. The contact was able to drive the vehicle to her residence after the failure occurred. The failure occurred sixty or seventy times over a period of one year. The vehicle was taken to a dealer where the mechanic could not diagnose the failure, because it occurred intermittently. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 84,000.

Removed the run flat tires and replaced them with regular tires. I am constantly having the "tire balance" light go off in my car and getting flat tires. Ever since I switched the tires the alignment has always been issue.

Approaching slight right turn on a park way at about 40mph, down hill of the right turn suddenly the slip icon light on the dash board was on and off with beeping sound alarm and observed grinding or braking sound on the vehicle which made jerking like on and off power of the vehicle. Road condition was dry and sunny at about 11:30 am.

The vehicle sustained intermittent brake failures. The brakes would function normally, then completely fail, then begin functioning normally again. This incident resulted in a low speed collision. The initial occurrence was after driving at highway speeds for approximately 20 miles and braking for stopped traffic. After braking to approximately 10 mph, the brakes were released, and then the brake pedal was applied again. There was no braking effort. The driver began pumping the brake pedal, and was able to do so three times before impact. The vehicle was then placed in park and an accident report filed. The vehicle was then moved under its own power to a nearby parking lot, during which time the brakes functioned normally. The vehicle was then taken home. The next morning the vehicle was being backed out of the garage and had another complete brake failure. The vehicle was stopped by placing the transmission in park. At this time, the vehicle is scheduled to be towed to the lariche Toyota dealership in findlay, Ohio for diagnosis and repair. The telephone number to their service department is 419-423-5656.
