| Description of the problem | When driving in dry conditions at various speeds over 25 mph, the vsc warning light comes on, an alarm sounds and the antilock brakes engage for no reason. This is a terrifying and extremely dangerous issue that is well documented by so many toyota sienna owners but to date has not been addressed or acknowledged by toyota. When taken to a dealership, they claim (as other owners have also stated) that they cannot replicate the problem and it does not register through the obd2 sensor so there is no record of it happening. With as many people as this is happening with, it is not a question of whether there will be accidents, injuries and ultimately deaths caused by this issue. The only question is when and how many have to occur before toyota acknowledges this is a problem. Driving down the road, in traffic at 65 miles an hour when for no reason, the car slams on the brakes without warning. It is happening all the time at this point making the car completely unsafe to drive for the owner, the vehicle |
