general problems of the 2005 Buick Rendezvous

I bought my car from a used car lot. I had it about 3-4 months and out of the blue it overheated very quickly, the warning light was on, some type of loud buzzer was going off so I pulled over and let it cool off, it took about 45 minutes but it started back up. I checked all the fluids and coolant levels and everything was ok. This continued to happen for about 3 weeks, quickly overheat, lights, alarms pulled over, checked fluids over and over. After about 3 weeks it would quickly overheat and then shut off on its own and several times it happened so fast I barely got off the road. I took it to a mechanic that drove it around a little until it overheated which at this point only took about 3 minutes to happen. He said there was air in my radiator and he released it and it was fixed, I drove about 3 miles and it overheated again so I returned to the same mechanic and after about 6 minutes he came and told me it was a head gasket but they didn't repair those there so I called the next closest mechanic who looked at the car for about 3 minutes, stuck an air hose in the radiator and he said it was blowing out gas fumes from the radiator meaning I had a cracked head. I had to tow it 200 miles to my house, my wife drove it back and forth to work which was only 1 miles from home, she was able to do that for about a month and then the engine would start stalling at different times such as slowing to turn, pulling in to park, and some times it would stall while driving in busy 4 lane roads. Well, a little over a month went by with all these things happening all the time and finally one day she came home from work and started to pull in the parking spot and it shut off again, we had to push it into the spot but once it shut off that day it has never started since.

In the spring of 2012 (approximately 48,000 miles), I was driving in a 40 - 45 mph zone, made a sharp left turn into a parking lot and the engine shut down and power steering to shut down. I previously reported this incident to my local Buick dealer, pinegar Chevrolet, branson, mo, just to have this incident on record. On December 29, 2014 (89,000 miles) this same type event occurred when slowing down (in a 45 mph zone) and making a sharp left turn into a parking lot. Car shut off, had to completely stop, place gear in park and restart. Sounds like same ignition issues discovered in gm cars recently, but the Buick Rendezvous has not been included.

We found out that we had a problem with my wife's vehicle. Initially, the vehicle was stationary. I took it to get an oil change and was asked to come into the shop to be shown that the antifreeze was like yogurt in the reservoir. We were told that we needed a coolant flush. This led to being told that we needed a new radiator; bypass hose; and last but not least, head gasket job amounting to approximately 1600. 00. We were told that there was no open recall but yet there was litigation going on regarding dex-cool antifreeze and that it was causing all of the problems that were and are having with this vehicle.

Have had to replace head caskets two times since I bought this now having problems with gas smell when I turn on heater whats next its got about 51000 miles on it.

I recently purchased a 2005 Buick Rendezvous cxl. As I was exiting the driver side door, the inner door handle gave me a fairly deep paper- like cut. There seems to be a rough edge on the handle that almost looks like the metal coating is peeling or separating and it sliced my middle finger on my left hand. I'm not very impressed and I am wondering how often this is going to happen? I think this should be a definite recall. It is not a life threatening injury, but very concerning considering I have 3 children and it couldv'e been one of them that received the injury instead of me.
