09 wrx hatch, the traction control and hill assist lights will illuminate sporadically. After the vehicle is turned off and then back on , everything works fine. I haven't found any variables that are consistent. It doesn't matter if it's rain or shine, hot or cold, both lights will just randomly come on.
The O2 sensor was replaced by resale dealer, after filling car with gas the check engine, traction control, and flashing cruise control light came on. Sensor was rechecked by dealer, and it is okay, codes wiped and reset. Car was filled with gas, lights came back on after commuting back home. Drove until there was 1/4 tank left, lights went off, filled back up with gas all the lights came back on. Sensor still tests back as the problem, but the sensor is okay.
As I was pulling into a parking space at work the hill assist light, vdc light, and abs light all illuminated. I turned the vehicle off and later turned it on and the lights were off. I drove the vehicle home and as I got off the highway the lights illumintated again.
