while driving about 35 miles or more the stabilizing service system kicks on, it feels like the car trying to stop while driving, and when you hit the brakes its like a vibrating feeling.
When turning the service stability system is displayed and the car puts on the brakes all by itself. It has also happened at speeds of 35 mph and the brakes lock up and car slows to almost dead stop. I take foot off accelerator and cost and within seconds am able to apply gas again. Almost got me killed yesterday.
Service stability system light comes on and when it does it kicks off my cruise control

I just had the same problem 2 weeks ago.
Just had the car try and kill me the other day while accelerating and at about 30mph, it locked the front right brake and veered right, almost onto the shoulder. I braked manually and pulled over restarting the car and it was fine. Been getting a service stability system message every now and then, but no symptoms until now. Going to replace the steering wheel position sensor. Heard that is a common fix. Go to Rock auto to find the part. It is made by Airtex/Wells and can be had for around $75.

Service Stability Sys message came up. Brought cat to dealer. They said it was a bad hub and oil pressure sensor? $850. dollars later I picked up the car and on the way home the jolted like I had hit the brakes then released. Service Stability Sys message and Service ABS message came up. Went right back to dealer. They said the steering wheel position sensor failed and $350 dollars later the car seems to be runningok.

Getting abs light and traction control light on. Als a service stability and service abs light. Braking assistant is turned off. Code says it's a steering wheel position sensor... Causes my car to engage the right front brake above 30 mph. Making the car swerve to the right towards the ditch or traffic depending on what lane I'm in. Miss very dangerous and it's my only car... I use the interstate to and from work but have been taking the back roads for now till I get this figured out...

Upon getting the 'Service Stability System' message, the car steering temporarily jerks to one side almost as if something is locking up. I took it to the repair shop and was told that the sensor on the steering pinion assembly as well as the sensor on the internal steering column was rusted. Since the sensor is attached to the steering pinion (found underneath the car), the whole assembly had to be replaced. Total repairs came to about $2000. And that was with discounts from the repair shop.

Stability sensor engaged, then my brakes grab and pull
it states that all the time when i turn too sharp.
While driving my stability control information light will come on and the back right side will pull hard to the right. And it threw a code for the steering wheel position sensor.

The car was fine until I stopped and turned it off. When I started it back up there was a whining noise like the power steering and then suddenly the wheel took a lot of torque to turn it. The fluid level is fine.
Power steering is leaking / spitting out power steering onto engine
