There was something about it on DFOAB and there's a guy you contact about defective ones. You'd have to send them in and they'll check them. More than likely, the tech did it wrong though.
Here's the answer from DFOAB:
"3/18/15 - Dallas response to Mr. Mace... Hi Mr. Mace, Thank you for the response and for the answers to the questions. Based on field feedback and validation performed, we all concluded that the repeated replacements of the torque sensor were related to technician training and not following the procedure steps. Most of the issues were related to sensor learning/reprograming after performing the recall. This can occur when the service procedure is not carefully followed. TAC call volume reduced significantly after the latest enhancement to the SI procedure/Video/communication/TAC Training. The first part of the installation procedure is the most critical (Steps 1-14). It includes all the steps on what should be performed before, during and after installing the sensor into the column housing. This is sensitive sensor so it is important to follow the latest procedure as published for correct installation. We have requested that any service parts which are perceived to be at fault prior to installation be returned for Engineering and supplier analysis. To date, no parts received have been found to have any issues other than improper installation. Although it should not be needed as standard practice, a technician can connect a new torque sensor to the Power Steering Control Module and check the voltage readings using the Tech2 prior to installing the sensor to the column assembly. These are noted as “Torque Sensor Signal 1” and “Torque Sensor Signal 2” and should be between 2.1-2.9 volts, with a preference to be as close to 2.5 volts as possible. This can be done to ensure that the part is correct before installation. Also, it is important that Power Steering Control Module Programming and Setup be followed in the correct order shown in the procedure. Remember that proper voltage must be maintained on the vehicle to ensure successful programming. Austin Ellis
2948 03/05/2015 3/5/15 - Dallas Walton (Brand Quality) left Larry a voicemail and followed up with an email using the TAC questionnaire. Dallas left him the necessary shipping address for parts to be returned for review - If parts are returned, the next step is to have them reviewed by GM Engineering for evaluation. "
