Fumes of evaporated coolant from faulty gasket were sucked into vehicles ventilation system. GM needs to take responsibility.

Coolant leak off of bottom side of motor. I own a 3.1 liter V6 and the cost of replacement is outrageous considering that I have been researching this problem on the internet and have several posts that have had the same problem. I have a 1999 Chevy Lumina, my coolant leak started over 2 years ago. I have not fixed it cause I don't drive the car that much, my car only has 90000 original miles on it. The leak of coolant is due to poor manufacturing of manifold gasket seal. Please refer to this website for more complaints:

I began having problems with my car overheating. I changed the thermostat and all the radiator hoses in order to fix the problem. Thinking that this corrected the problem because my mechanic could not find a leak I continued to drive the car. It was not until I had to start using the heater in Oct 09 when the problem recurred. I then used radiator flush and cleaner and still my mechanic was unable to find the leak. I was having to put antifreeze in the car several times in order to make it to work (usually a 15 min drive). One cold morning I noticed the car was smoking from under the hood and was able to make it to the mechanic shop. It was at this time that he showed me the leak at the intake manifold. He was able to fix the problem, but informed me that this is a recurring problem with this car. The fix is only temporary. It cost me several hundred dollars to fix the intake manifold gasket (650.00). This does not include all the other work and repairs that were made prior to replacing the intake manifold gaskets. I changed the thermostat twice and all the radiator hoses before finding the leak in the intake manifold and getting it fixed. I would also go through a gallon of dex-cool antifreeze every other day; at a cost of $14 plus tax. The old part is no longer available. My mechanic showed it to me and it was eaten up. He told me he has fixed hundreds of cars with this same engine and problem...

My Lumina suddenly began to loose refrigerant causing the car to overheat. Took the car to several shops including a dealership and the diagnosis was a lower manifold gasket. Each and every repair facility said this is very common in the Lumina. With 56000 miles I am now faced with a very expensive repair.if this is so common why has nothing been done about this.? I have had an air conditioner replaced as well as many other expensive items. I am paying twice for this vehicle in repairs. The position of the battery makes it impossible for a person to replace themselves. The Lumina is turning into a money pit.

I have a 1999 Chevrolet Lumina. A couple of weeks ago my car started to over heat. It became increasingly worst. The car was leaking coolant severely. I took the car in to the shop and was told it was the intake manifest gasket. I never knew how much this was a problem until I started to research this. It will cost be about $350 dollars to have it fixed. I have also had to replace my water pump.

Only by observing a slight but lesser coolant level in the overflow jug of my 1999 Lumina L/S passenger car, were we made aware of this costly defect at such an early stage. A subsequent and closer look at the applicable areas, resulted in confirmation of a leak at the intake manifold. At a cost of $850 to replace gaskets and vital fluids, I was very surprised to encounter such a heavy duty repair for this low mileage and vigilantly looked after Chevy product. Fortunately for me the discovery was made prior to an engine overheat, which would certainly have resulted in more sever and expensive repairs. Much thanks to my husband for his meticulous care of our Chevy vehicles.

(1) our '99 Lumina had an intake gasket failure and a water pump failure which I was told is due to a design failure of the gasket (2) thankfully we found the problem soon and the engine wasn't effected (3) the shop replaced the intake gasket set, water pump, replaced coolant and seals at a cost of $795.13.

My 1999 lumnia, at 28,000 miles developed a coolant leak around the intake gasket and head gasket. Was small but dealer replaced the battery, then a week later the alternator, at 38,000 the coolant leak was very noticeble. $$$ to replace gaskets when I was told the manufactuer knew of the bad gaskets used in its manufactureing.

There was coolant leaking from underneath the vehicle, causing vehicle to overheat. Dealership is aware of problem.
