- the contact owns a 1999 Pontiac Grand Am GT. The vehicle's current mileage was 61,000 miles and the failure mileage was 60,900. She took the vehicle to dealer for an oil change and inspection. The dealership informed her that the vehicle was leaking antifreeze and oil, and the intake gasket needed to be replaced. She found many complaints on NHTSA website for this same problem for the engine and engine coolant: Exhaust system: Manifold/header/tail pipe. The dealership informed her that this will cost her $1,100. She would be contacted by the GM manufacturer. There was no indication of this problem, and was surprised when the service department informed her of the oil and coolant leak. Updated 05/21/07

Intake gasket on 1999 Pontiac Grand Am failed for the thrid time. The second time I almost had engine damage. The car overheated and warped the heads, but was not enough to be replaced.

Where to start, .bought 1999 Grand Am GT in August of 2002 and ithas been downhill ever since. Replaced the alternator twice, have experienced the same intake manifold gasket problem, which was replaced, but still led to the demise of my engine, causing camshaft to snap in half. Thought the trouble was over with the rebuilt engine that was put in, but that was not the case. The window regulator broke in the middle of a snowstorm, causing me to drive with no driverside window. With the new regulator I assumed that the window would stop squeaking, which did not. I assumed the scratches on windows were just from me-sand or some other abrasive material in the window tracks--after reviewing other complaints I discovered I was not the only one with this problem. Have experienced various issues with the no trac/ABS lights, replaced the waterpump, done brakes 4 times in 4 years, front headlights are milky and make it hard to see at night. Have replaced the starter 4 times in just the past 2 years. Needless to say after reading all complaints I feel much better knowing that it is not just me, or my car, but all Pontiac. Bought the car for $10000, have put over $5000 worth of work into it. Will never buy another Pontiac.

After about 100,000 miles, I was told the intake manifold gasket on my Pontiac GM 1999 Grand Am needed to be replaced (coolant was leaking and after investigation I saw that the dexcool coolant was to blame for wearing of this intake manifold gasket). Of course, my vehicle is not under warranty, and GM will not cover it. If I didn't pay (or have ) the $1000 to fix this, I was probably going to ruin my engine. So, I needed to save up, and I am afraid that when I take my car in tomorrow for repairs, they will tell me the engine will have problems. There are many people complaining about this issues with the delco intake manifold gasket. This was the first vehicle I purchased as new, and even though I work for the american auto industry, this is deterring me from buying from GM again. I would appreciate them taking responsibility for a defect that should not have happened.

Coolant light began to come on increasingly often so I had it checked out at the garage where I work. I was told the lower intake gasket was leaking and if it didn't get fixed water and antifreeze would get into my oil. This car only has 76, xxx miles on it. I know of two other people that own these cars and they have the same problem I do. This is not safe if the engine freezes up.

Failure of lower intake manifold causing coolent and oil to mix in engine.

- Cleveland Heights, OH, USA

Low coolant light would come on for a few seconds then shut off. Made sure coolant was full, still kept happening. Stared overheating and no heat. Mechanic looked said there was air in the cooling line so he flushed and refilled, could not see any leaks. Same thing happened again with in a week. By this time my check engine light came on. Went back to mechanic and he then did a number of tests and found that it was the intake manifold gasket leaking. After paying $700 to have that fixed got the car back and engine light was still on and using allot of fuel. So took it back again and after extensive testing found that it was my piston rings were bad on the 3rd cylinder and that it would be cheaper to replace the engine than fix the problem. With so many cars with the same problem (not just a few, most of them) I can't believe that Pontiac will not back up their products. Pontiac has turned out to be a big disappointment.

I have a 1999 Pontiac Grand Am. It has been in the shop at least every three months. The brakes have been replaced 3 times and the rotors twice. I take the car to an independent mechanic due to the dealer always saying nothing was wrong. The water pump went out, the manifold gasket cracked, the low track light has gone on since the day I bought it every time I turn left or right. The windows scratch and have been replaced once and scratched again about 2 months later, the dealer said it was the tinter that ruined them so I paid. I cant do that again so they remain scratched. I looked at a website mycarstats.com and there were 526 complaints and every single one had the same problems. I work with 5 other people that own Grand Am and we've all had the same trouble. Something has to be done, why do we have to be stuck with 1000S of dollars in car repairs and the manufacture not assume responsibility. I've had problems since I purchased the car brand new so there are several incident dates. Thank you.

Have replaced the entire intake manifold on this car three times. 1999 Grand Am, purchased new, has less than 60,000 miles on it. In addition, have replaced power steering twice and brakes numerous times. Replaced alternator, serpentine belt, battery, starter on ignition, molding due to leaks, wiring on dash, air conditioning resistors/circuits, and headlights/taillights.

My wife's 99 Grand Am (Pontiac) has a problem with a failure of the intake manifold gasket. This seems to be a chronic problem with GM engines, and will cost over $800 to repair.
