In June 2009 I had to replace the rack and pinion steering on my 2006 Silverado weith only 50, 627 miles on it. GM would not do the work under warranty...cost $1, 290.23. Today I took the vehicle back to the dealer...leaking steering fluid. I have to replace the rack and pinion again, with only 70, 000 miles. The truck is never off-road and used in the city/normal highway driving. Again, GM won't honor the work they did last year. Apparently warranty on parts is only 1 year. read full review »
