2005 Buick Rendezvous: engine overheating

Filed Aug 28, 2023 · Electrical, Engine · WV

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

Car was sold to me in 2018. First day driving after purchase, overheated after going maybe a mile down the road. Have had several instances where this has happened, and several different parts replaced. Head gasket, water pump, thermostat, radiator flushed/filled, motor mount and left stranded several occasions due to this issue. Twice having to walk in the winter with my daughter. Vehicle overheats in motion, stationary and regardless of city or highway.

Vehicle overheated to the maximum, then it stalled. I waited a bit and was able to restart it. The temp. Returned to normal. While continuing to drive home at 35 mi per hr. It stalled again, and I was able to restart it, and make it home. I phoned my mechanic, and had it towed there. He informed me there was water in the exhaust which indicated expensive head gasket problems. He suggested I sell this vehicle asap. I had only owned it 2 months! When this problem occurred I was in motion at 35 mi per hr. On a city street. Very dangerous!

I took my car to the local gas station about 3 minutes from my house. I went in came back and out and before I was even halfway home my car started to overheat. I hadn't even driven half a mile. The thermostat and the coolant temperature sensor have been replaced and the radiator flushed. There was all sorts of brown gunk in the line but the issue still is not resolved. The heat only works occasionally after this and the car still will run hot and then drop back down to a normal temperature all within 2 minutes. No one is sure of what is going on with it. The cause cannot be found at this point.
