Those errors can be triggered if the computer thinks the engine isn't running right. Happened to me when I failing fuel pressure regulator (attached to the fuel pump in the tank) causing intermittently high fuel pressures at the rail. New fuel pump cured it in my case at 210K, but I suspect a cam phaser problem would also result in the same codes because the stability control system requires the engine to be running within known paramters to remain engaged. You didn't disconnect the steering shaft in any of your repairs, did you?Alright, I did a little more digging and iv found the issue. Ended up being a large crack in the plastic of the radiator on the driver side and was bring blown to the passenger side it looked like. It is now holding coolant, but i have the traction control and sabiltrak errors now, any ideas on fixing that?
