08 Malibu LT 2.4 ecotech 117,000 miles ... The last couple of weeks the wife has been complaining of a hit or miss power steering failure that's especially causing on the first start of the day. The last few days the issue has progressed into a reoccurring issue everytime we go to drive, if the power steering works it's constantly vibrating and pulling and then the pump goes out... I've already checked apparently this vehicle had the recall fix about 5 years ago, I've only owned it for three.. So my question is?? Is it the power steering assist module? Is it the steering wheel position sensor? Any ideas on where to get a discount power steering assist module? Any help would be greatly appreciated.
