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.
