| Description of the problem | I noticed an article recently about a probe into toyota's (camry and lexus) that surge. My 2004 toyota sienna surges forward when braking and though it does not do this consistently, it happens every so often and could potentially cause an accident. I have reported this to the dealer and they have examined the vehicle and said that there is nothing wrong. My personal experience with the electronic throttle control is that not only does it surge when braking, there is also a delay in the signal when accelerating that either causes an unsafe delay in entering into traffic and can also cause the vehicle to "peel out" from a stopped position. I basically feel unsafe in this vehicle, yet my concerns voiced to the dealer have been dismissed. This defect needs to be seriously monitored in siennas as well as other toyotas with the electronic throttle control.*ak |
