Buick Rendezvous overheating problems

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.

Tl* the contact owns a 2002 buick rendezvous. While driving approximately 35 MPH, the vehicle started to overheat and the temperature gauge started to flash. The vehicle was taken to an unknown independent mechanic where it was diagnosed that the intake manifold gaskets were damaged and it would be best to rebuild the engine. The dealer was not contacted. The manufacturer was not made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 169,000.

My vehicle did not have heat. I was not able to determine if it was blowing cold air or not blowing at all. Before I had a chance to address the heating issue, the vehicle ran hot and continued to run hot until a mechanic replaced the thermostat and the coolant and cu at 2/3 slit in the rubber under the hood. It came to my attention that the vehicle had overheating problems before it was sold to me. I have since tried to sell it and found th st it was not accepted by two car buying/selling websites due to previous salvage. I purchased from a buy-here pay- here. It still has over heating issues and it still has not heat blowing inside. I want to know if repairs will help since it's regarded as a salvage. Is it lawful to sell a salvaged vehicle knowing the purchaser was putting the car on the road? I bought the car in ohio and I live in new york.

The vehicle was running for 45 minutes on two-lane paved country roads. I drove the first 15 minutes, with one of my sons driving the other 30 minutes while I was a front seat passenger. We pulled into a parking lot and switched drivers so another son could begin a driving lesson with me. When he began to back out of the parking space he said that the brakes did not feel right and noticed what I thought was steam coming from under the hood. I told him to pull back into the parking space and release the hood so I could check for an overheating engine, even though there were no warning lights on the dashboard and the temperature gauge was in the center of the visible range. When I opened the hood I saw a six-inch wide area of flames to the right of the alternator. I told my sons to get out of the vehicle and asked one of them to call 911 on his cellphone and the other to go to the nearest building, about 75 yards away, and look for a fire extinguisher. In the meantime, I opened the rear vehicle hatch to look for something I could use to put out the fire. Finding nothing useful, I ran to the building my first son had approached for a fire extinguisher and found him inside the outer door of a locked lobby area. We both ran to the next building about 100 yards away where we located a fire extinguisher and returned to the vehicle. I estimate this took less than five minutes. When we returned to the vehicle the flames were about twelve inches wide, still only to the right of the alternator. I was able to quickly put out the fire, but had to aim much deeper into the engine compartment than the visible flame area to stop all flames. When the dealer later checked the vehicle I was told it appeared that a ruptured brake line had sprayed brake fluid on the exhaust manifold and started the fire. There had been no prior leaks or brake issues observed.

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!

It started overheating , a very reputable mechanic checked it , said it was possible radiator , then said said may be gaskets . I saw where others had overheating problems on the internet . Will the company pay for this to be fixed and are their other safety issues with this car I have a disabled son and do not want to be out in it and have it catch fire or worse .a older lady owned it and her sister sold it to us when she had to go into the nursing home its been well taken of its a four door.

I purchased this car on june 23 and the next day it wouldn't start took it back to the dealership and they replaced the battery and the alternator said it was fixed but several hours later the car wouldnt start again took it back the next day and they said it was the air conditioner running while the car was off draining the battery so they took the fuse out and said they would fix it the next day but when I called to take my car to them I got no answer from them. Three days later the car overheated and I got it completely checked by a different mechanic to see why my car is running hot and he gave me a list of problems every head gasket is blown out and the motor is gone. He said that there was a recall a few years back on these types of buick cars for the coolant and the wrong coolant was placed in the car and it messed up all head gaskets I immediately called the dealership but again no response I called the bank because I still have a 30 day tag and only had the car for two weeks but again no response I called buick and spoke with someone to ask about the coolant recall and he said he would call me back in a hour and again no response. I asked for a carfax report and the dealership said they didn't have one but gave the couple behind me a carfax for their car the brakes and rotors are completely gone I cannot stop with my brakes I just have to coast so I want hit anyone this car will stall out on me without any warning. There has been no action taken from the bank or the dealership on how we can fix this problem they have all been ignoring and not responding to my calls texts or anything.
