Ignition Module problems of the 1998 GMC Jimmy

I have 86,000 miles on my 1998 Jimmy and dropped my granddaughter off at the my other daughters place, the key turned off no problem. I drove to work and could not turn the key to the acc or off position and could not get the key out. I checked the website and noticed that this happened to a couple of other owners who ended up paying over $700. 00 for the repair, which included replacing the ignition module and reprogramming. This happened at a time when I am going through a divorce, my other daughter is in the hospital and my father is having heart problems, so it really is inconvenient and with all that is going on, has changed my attitude regarding GMC's. I used to swear by them, now I am thinking of looking at other dealers. I had the head gasket blow on this model, when they repaired it, they dropped a bolt down inside the piston, which they did not catch until it cracked the piston, which delayed me getting my vehicle back. They misdiagnosed a control module that would sound like the signal kept turning on by itself, they replaced my brake pads stating that goodyear installed them wrong, because they kept squeaking. I paid $200. 00 to have them replaced and they still squeak. This was done at jim lupient in st. Louis park. The technician after repairing the engine forgot to tighten the air intake clamp down and it vibrated against the air-conditioning hose, which cut a hold in the hose and drained all the freon. When they repaired the hose, they did not evacuate the lines, so the air-conditiioner sounds like it gurgles at startup or when you step on the gas.
