Sorry guys but finally got my car back--took forever. Battery and alternator was fine? but the fault code was 5EC0. A steering angle sensor was faulty. Here's what they typed on the paperwork:

53642 internal fault in SZL performed short test and found fault codes 5EC0. Performed test plan S3450_L4_LWS-sterring angle sensor adjustment test plan was successful. DCS light came on during road test, scanned vehicle again and same code 5EC0. Performed test plan again and calibration with encoding and the SZL keeps changing to zero point during calibration. The SZL is faulty but will not give diag code for failure to initialize the correct angle. Left feed back on ISID. Replaced SZL and programmed SZL with CAS.
