My 2010 HHR is driving me insane....The ESC light comes on randomly sometimes it jerks and grabs at my brakes the traction light will come on the security light and sometimes abs will come on the radio will go in and out and sometime will change on its on from radio to cd or audio input the car may or may not depending the cars mood lose power while driving then it will just take off...HELP I've been to the dealer twice each time not finding a problem however gives me possible solutions like change the angle sensor and get new tires front end alignment HELP......

 

Strange that the dealer couldn't find the TSB. The problem is usually either the engine harness connector to the ECM or the harness itself getting burned or chafed.
