No recall but there is a tech bulliten, it has to do with a code C0900 and needs to be scanned first. but here's the TSB:
Loss of Power Steering Assist, Power Steering Warning Message Displayed in DIC, IPC/Radio Displays Erratic, DTC C0900, B1325 Set (Replace Ignition Coil/Module Assembly and Add Ground Strap) TECHNICAL SERVICE BULLETIN Reference Number(s): 08-02-32-005, Date of Issue: May 12, 2008 Related Ref Number(s): 08-02-32-005 ARTICLE BEGINNING CONDITION Some customers may comment on a loss of power steering assist at high RPM (above 3500 RPM) and a power steering warning message displayed in the DIC. They may also comment some instrument/radio displays are erratic. Upon investigation, the technician may find DTC C0900 set. If the displays were erratic, then DTC B1325 will also be set. CAUSE This condition may occur when the system voltage exceeds 16 volts for one second for code C0900 and the system shuts down to protect it from over-voltage operation. If the voltage exceeds 18 volts for five seconds for code B1325, then other electronic systems protect themselves and shut down. It has been found that this voltage increase is caused by an interaction between the alternator and the ignition coil/module assembly. CORRECTION Replace the ignition coil/module assembly and add ground strap following the procedure below. 1. Disconnect the ignition coil electrical connector. 2. Disconnect the left side spark plug wires from the ignition coil. 3. Disconnect the right side spark plug wires from the ignition coil. 4. Remove the four bolts attaching the ignition coil to its mounting bracket and remove the ignition coil. 5. Remove the ignition coil from the mounting bracket. 6. Loosen the two lower ignition coil mounting bracket nuts. 7. Remove the two upper ignition coil mounting bracket bolts and discard.

Install the new bracket bolt, P/N 11570082, (do not tighten at this time). Prior to installing the ground strap, remove the captured nut and washers. They are not needed (simply pound them out with a hammer on a vise). 9. Install the washer (2), P/N 02436162, to the upper right side of the bracket between the coil bracket and intake.

How important to this solution is the washer P/N 02436162? I've replaced the ignition coil, the 80 amp fuse and installed the ground strap as recommended in a YOUtube video for the same problem. The problem went away for a few days and then returned. I connected the strap to the position 2 where you recommended placing the washer in your response. What did I do wrong? What else can be done to remedy this issue?

Thank you, Ken. I've read where others have replaced the motor assemblies only to have the problem return. What info to you have that replacing the PSA module is the accurate and final fix of the root cause? If this is truly the FIX, then why won't GM own up to their mistake of installing bad parts and do a full recall? 13 people have died due to this issue with these models!

I did find a TSB on the issue which as follows

REPORT RECEIPT DATE: February 04, 2015

NHTSA CAMPAIGN NUMBER: 15V064000

COMPONENT(S): Steering

POTENTIAL NUMBER OF UNITS AFFECTED: 69,633

ALL PRODUCTS ASSOCIATED WITH THIS RECALL:

VEHICLE MAKE MODEL MODEL YEAR(S) Chevrolet Malibu 2006-2007 Chevrolet Malibu Maxx 2006-2007 Pontiac G6 2006-2007

DETAILS:

5 Associated Documents

MANUFACTURER: General Motors LLC.

SUMMARY:
General Motors LLC (GM) is recalling certain model year 2006-2007 Chevrolet Malibu and Malibu Maxx vehicles manufactured April 1, 2006, to June 30, 2006, and 2006-2007 Pontiac G6 vehicles manufactured April 18, 2006, to June 30, 2006. In the affected vehicles, there may be a sudden loss of electric power steering (EPS) assist that could occur at any time while driving.

CONSEQUENCE:
If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.

REMEDY:
GM will notify owners, and dealers will replace the torque sensor assembly, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Chevrolet customer service at 1-800-222-1020 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14772. Note: This is an expansion of recall 14V-153 to cover additional vehicles built between April 1, 2006 and June 30, 2006.

NOTES:
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www. Safercar. Gov.

Looks like its the torque sensor that needs replacement. Here is the fix

Thank you, Ken. This information will be very helpful!
So do you think the torque sensor replacement and not replacement of the PSA Module (motor)should be the final fix or do they both need to be replaced? I called GM before to check if this vehicle has been recalled and they told me it had been and that the torque sensor was replaced. Since then, the problem had returned. What do you think?

To find out exactly whats going on a CAN scan needs to be done, Here is a video but I would start with the sensor since there is a bulletin. I know you replace it once already but if it is an issue it could be out again.

Okay Ken. Finally got the car to the dealership. The did a diagnostic check and came back worth the problem being the Steering gear? I asked how this part could be related to the issues with the power steering failing and he wasn't sure. Says that's what his technician is telling him.
What's your feelings on this? I haven't given them the go on repair just yet. I want to read more to see if this $900.00 repair will fix my issues once and for all!

You can do it yourself, but you will need a scan tool to set the module up. If you do the job a shop can calibrate it for you for about $130.00. Here are the instructions to do the job in the diagrams below.
