Sitting in a parking lot and the VSA light came on. Looked it up and saw the recall on the VSA so intended to get it checked out. A couple days later I'm tooling along at freeway speed and for a brief second it felt like someone slammed on the brakes and released, and the VSA light came on.

Took it to the dealership and the codes they found were for some sort of a power drop and blamed it on a possible power outage or drop at some point. Maybe alternator, battery or something, but they didn't find anything wrong with any of those, but it cost me $125 to be told they don't know. The VSA recall was completed in 2012 for the wiring harness. Today (a week later) I'm going about 25 on a surface street and the exact same thing happened, so I took it to the dealership without turning off the engine and possibly clearing any codes.

What they came back with was a faulty Yaw Sensor code, but they want to keep it for a couple days to do further research. I'm told it is connected to the main computer and if it is the Yaw Sensor then the main computer has to be replaced, at a cost of $1650 (they will credit toward the repair the $125 I paid last week for the non-answer).

In reading online, I'm not the only person who has had this issue. Also reading online a quick review seems to lead me to believe that the sensor CAN be replaced by itself, separate from the main computer, at a much lower cost. Any input?
