Continuous issues with traction control system almost daily. Any time vehicle veers towards the right anti-slip indicator light, alarm sounds and ABS system activates. This happens almost daily, on dry roads, going downhill or on a curve, even while switching lanes now. This happens above 20 MPH. Driving becomes stressful and worry-some when alarm begins to sound and dash light come on. Fear of losing control becomes great, fear for your passengers safety as well as other drivers safety becomes real. During the past 3 months there have been 5 separate incidents in which the vehicle has lost acceleration, pulls steering in one direction and sudden break lock occurs. 2 of which took place on the freeway on ramp at a speed of 35mph, 1 driving downhill, slightly towards the right, at a speed if 20mph and the last 2 while switching lanes, 35 MPH. Vehicle began losing power and slowing instead of increasing speed. There are many complaints regarding this issue with many drivers in many areas. Why isn't this being investigated?

Sudden loss of power by model year
What owners say
The traction control system is activating improperly. The vehicle's anti-slip indicator warning light illuminates; an alarm sounds; the ABS system activates; and the vehicle sometimes loses power. This happens on dry roads, most commonly either going downhill or else on a curve, even a mild one. This happens above 20 MPH. When it happens, the combination of alerts and sensations are very startling to the driver, creating a dangerous situation. It has occurred while trying to accelerate to merge onto a highway. This was exceptionally dangerous as the vehicle began losing power and vehicles behind us almost hit us from behind as we were slowing instead of increasing speed. From my internet searches (including the federal safety agency complaints), this appears to be a recurring issue with this make/model/year range. This has been happening for the past 3 months. Our vehicle has approximately 135,000 miles on the odometer.

2005 toyota sienna: power steering fails intermittently, resulting in a loss of power steering and sudden increase in steering effort, increasing the risk of a crash. Driver is at risk if sudden steering away from an event is necessary due to the effort and inconsistent nature of the steering. There are many complaints about this that can be found on various forums on the internet. It is a serious problem that should not be ignored and should be addressed before rather than after someone dies as a result of this vehicle fault.
2005 toyota sienna had cruise control on. The vehicle began to 'shake' and the speedometer climbed to 80 MPH then down to 60 MPH. It didn't seem to actually be accelerating--it felt like the vehicle was fighting to not lose power. I deactivated the cruise control by touching the breaks. I pulled off the freeway, turned the motor off, waited and started again at a slower speed without the cruise control on. After a while the vehicle again began to 'buck and shake', the speedometer raced to 80 MPH (though the car itself) did not seem to have rapid acceleration) then the speedometer dropped to 50 MPH. Over the phone my husband advised I turn on the cruise control and turn it off again. I did and drove about 45 minutes home at speeds from 55-65 without another incident. I will take the car to a dealership tomorrow to check out. The vehicle has approx. 100,000 miles on it.

- What is wrong
- Toyota is recalling certain model year 2004 avalon vehicles; 2004 and 2005 camry, camry solara, highlander, and sienna vehicles, 2006 highlander hybrid; 2004 and 2005 lexus es330 and rx330; and 2006 lexus rx400h vehicles manufactured from june 1, 2004 through march 31, 2005, equipped with the 1mz-fe or 3mz-fe engine. The amount of adhesive agent applied between the outer ring and the torsional rubber damper (inner ring) in the crankshaft pulley may be inadequate. If the adhesive is insufficient, there is a possibility that the outer ring may become misaligned and it may not properly rotate with the inner ring, causing noise and/or illumination of the battery discharge indicator light.
- Risk
- In some cases, the belt for the power steering pump may become detached from the pulley which could result in a loss of power steering and a sudden increase in steering effort, increasing the risk of a crash.
- Remedy
- Toyota will notify owners, and dealers will check the crankshaft pulley to identify whether it was produced by the u.s. Supplier. If so, the dealer will replace the pulley with a new one at no charge. The safety recall is expected to begin during early january 2012. Owners may contact toyota at 1‑800‑331‑4331.
