i had many issues with my power steering going out on me while drving various speeds or turning , or even hitting a bump>> Doing research i called GM and told them i got a 05 g6 with 62,000 miles at the time ( last year) and they did have a TSR out to replace steering Columns on 05 G6's.. Got it replaced at NO cast to me and have not had a problem with the steering column since , and now i got 70,000 miles on it..
