I have a 1999 Chevy Lumina purchase new in 1999. The intake gasket has ben serviced on 3/14/03 at $216, on 12/15/03 car smoking and fluid leaking again and this was $737. Now I have been faced with the same problems. For several weeks I was adding coolant on a weekly basis until it started to be every 2-3 days. Then the car started smoking and I panic and took it to the nearest shop on my way to work. The manager told me that it was a intake gasket manifold problem. When they were done it had cost me $763 dollars. I was told that there were other vehicles in their shop with similar problems. However, after leaving that same day, the car begun hesitating when accelerating as though it was not getting any gas. That made no since because I had 3/4 of a tank of gas. Why are these problems happening at this point because I have consistently serviced this vehicle on a regular basis since purchasing in 1999. I am told that there are recalls on these particular problems. Please help me because I value and take good care of my cars, but I feel that everything is defective. I have also had issues with having to have brake jobs every 6 mos. On this same vehicle. What is the problems. Will you help.

Vehicle was running hot. Took it to midas, midas who said it was a intake manifold problem with the plastic cap and needed to replace it for total of $700. Midas said they have had a lot of customers with same problem due to antifreeze strength the dealership was required to put into vehicle. Also having problems with vehicle stalling, and when filling vehicle up with gas, which seems to run out or maybe leak out fast.

My car was parked in my garage and I notice anti freeze leaking. I had the car looked at and was told it is the intake vavle that needs to be replaced. I am going to have the repair done and yes the replaced part is available. My vehicle is a 1999 Chevy Lumina and I only have 60,000 mile on it. I have maintained my car according to the manual and have had several major problems with it. I have had to replace 2 fuel enjectors. I replaced the altenator at 41,900. I am very good at keeping my car maintained and it has never been driven rough. I am the only owner and the car had less than 100 miles on it when I bought it.

My starter recently went on my 1999 Chevrolet, Lumina, upon repair it was found the failure was due to a short created by a seal failure in my engine. The antifreeze is leaking out my engine block from the manifold/seal and onto my starter. This was saidd to be due to the plastic seal used on the aluminum engine. It is said to not be "chemically compatible" causing "inevitable warping of the seal". the cost for repair is be $600 just for a new seal. But at 54,000 miles they suggest to due the standard maintainance while the engine is out like tune up, transmission flush, etc. Looking at a cost of $950. This has been told to me by several mechanics to be a "manufactures defect" but it has been overlooked due to the overwhelming numbers of Lumina's that have beeen sold. I find this unexceptable as a buyer who trusted GM and cheverolet consumer reports and its overall reputation of quality. Now I feel like I am driving a time bomb which can't be sold without my loss due to its faulty seal and the required repair. I had to replace my battery first because I was loosing power ($65) and then had to try process of elimination by the suggestion of auto zone and their computer read out. My car was still not starting so then after having my car towed, due to the short in the starte. I had to have my starter replaced due to the leak from my engine and the cost then (for a lifetime warranty) was $182 plus the antifreeze flush I paid for to try and stop the leak. I am very disappointed. How can such a defect be accepted by such a prominent manufacturer.

Manifold leak developed at 62,840. Miles, resulting in loss of coolant and a $500. Repair bill. Now I see from this site that many, many others have same problems with GM 3.1 liter V6 engines! N.a.H.

Intake manifold cracked...gaskets leaking. Coolant wont stay in engine. I have researched and many 1999 Luminas (3.1 V-6 are having the identical problem) approximately cost of repairs $1,000 GM is definitely aware of this huge problem. A total recall of this vehicle and correct this problem must be made immediately.

1999 Chevrolet Lumina, only 70,000 miles, have had the injectors flushed X3, now need manifold replaced and head gasket replaced, costing approximately $1000. Problem related to defective gaskets on Chevrolet's part should be paid for by Chevrolet, not the auto owner. Chevrolet has been aware of this problem and there are numerous persons having to replace parts due to their failure to make a correction or a recall. I want Chevrolet held responsible and to reimburse myself and others that have had to have this done to their vehicles.
