Flow Chevrolet Buick GMC

We took our 2005 Saturn Ion in on 4/10/2014 for the well known SIR coil problem. Flow installed a new coil and charged us $89 for the diagnostic test and $348 to replace the coil. The next day after we brought it back home the power steering went out. We took it back to Flow and they said it would cost $99 for the diagnostic and we would have to pay for the power steering to be repaired and that there was no recall. I have no idea if its a very strange coincidence that the power steering went out the day after we took it to Flow or if they had to remove the steering column to fix the SIR coil and didn't put something back right, but why wouldn't the first diagnostic find the problem if it was there before they worked on it and why charge us for another diagnostic? Apparently GM doesn't inform the dealerships before they send customers recall letters and until GM posts it on some GM website Flow will not fix it. I can't post links in this review but GM does have a post on their media site about the recall. The Title is "GM Recalls Older Model Vehicles to Fix Power Steering". We own 4 GM vehicles, purchased the other 3 brand new, 2 from Flow. We were test driving 2 new vehicles the day we took the Saturn in for service the first time, they have definitely made the decision not to buy those two vehicles an easy one.
