: the contact stated while driving at various speeds the engine overheated. The vehicle was taken to an independent repair shop for inspection. The mechanic determined the engine's high performance additive caused corrosion to the aluminum cylinder head. The cylinder head was replaced which corrected the problem. Updated 3/28/2006 - the water pump failed. The battery and brakes failed. The coolant light illuminated. The dealer determined that the antifreeze had congealed and needed to be flushed and replaced. The driver side headlight went out. The driver side window regulator broke.

I purchased my 1999 Pontiac Grand Am GT in Feb. 2003 with 55000 miles on it. In June 2004 without any kind of warning it dumped every ounce of coolant 2 blocks from my house. I had to have it towed to the dealer where they diagnosed that the manifold gasket had blown and my battery was no good. There had not been one problem with the battery until the gasket blew. I had the car repaired (500.00 dollars). Then this past April 2005 I had to have the water pump replaced. Two days ago I notice a puddle of coolant under the car, I investigate it's origin and there is a stream of coolant running along the seam of the manifold gasket! I haven't even put 10,000 miles on this car since it blew the last manifold gasket. GM knows there is a problem here, show some integrity and take care of these problems!

My 99 Pontiac Grand Am is slowly leaking anti-freeze, the mechanic I went to knew exactly where to look, the intake manifold. He said they are getting one or two each week and did not know why they have not recalled the vehicle. I figure this would be an environmental concern and I have never heard of any vehicles leaking a coolant after only 60,000 miles.

When driving steadily over 50 mph for a period of 15 minutes or more the engine revs at 2000 RPM or higher. When going into neutral or park it reaches 3000 RPM. This is an intermittent problem. In the beginning it would stop once I turned the engine off and restarted it. Now I must sit and wait for the engine to cool in order for it to stop happening. I have not yet repaired this because I have not been able to recreate the problem when brining it in for service. The service engine light does not come on.

I have a 1999 Pontiac Grand Am GT, and have had problems that the dealer refuses to fix since day one! the first day that we brought it home, dealer had to come and tow it back to dealership because the alternator went out, suddenly with no warning whatsoever. Dealer fixed that problem because it was under warranty. We had a problem with the radiator soon after that, dealer refused to fix it even though it was still under warranty. I had to pay out of pocket, still. Recently, within the past 2 months, the intake gasket manifold is leaking antifreeze. Car ran hot suddenly and without warning. Dealer refuses to fix this because the car is no longer under warranty. This in itself will cost me another $700 out of pocket, not to mention all the other things wrong with the car. The leather on the door is peeling and folding, dealer refused to fix even though we had written orders from the manager to fix it. The driver side window squeaks and rubs when opening and closing. We have called and talked with dealership over and over again with no avail! I have maintenance done to the car every 3000 miles, so this is due to no fault of my own! all in all this car is a lemon! I will never buy a GM made car again! something needs to be done. My son could have been killed and my husband and I also! this needs to be addressed. Obviously GM knows about this problem, will they wait to do something about it until someone is killed?

Last year went to my dealer for routine maintenance and service tech "suggested" I buy a new car, because the problems they discovered were going to be over $4,000 to fix. Thought this was strange as I have only had the car for less than 3 years. My mechanic fixed the coolant intake manifold for a lot less than the dealer but said he has seen this in GM cars before and GM knows about this issue. They have recalled vehicles in the past for this problem. Apparently the glycol coolant eats the gaskets and causes the leaks to the rest of the systems. Fixing the gasket with the new and improved version just delays the damage that has already been done, and the recall that may happen one day, after we have all sold or junked our cars. Which I am sure is what GM is waiting for. Next time I buy an import.

(1)our low coolant light illuminated so we topped off engine coolant. We were turning around a curve at about 45mph and when the low coolant light came on again. (2) fortunately we were just finished a right curve on a secluded road or we would have veered into oncomming traffic when all power steering was lost. We regained control without power steering, lights or brakes on the passenger side. Upon investigation we were able to determine fluid discharged from the reservoir and covered engine belts, brakes and tires on passenger side therefore making them slipp. This is what caused power steering, lights, brakes and traction loss. If the driver was of less strenght and awareness, the conditions were wet or traffic was heavier this could have possibly been a disturbing accident and possibly fatal. (3) it was discovered that the vehicles lower intake manifold gasket leaked which caused the overheating and discharge of fluid. Vehicle had less than 60,000 miles. A friend of ours has the exact same vehicle and recently repaired the same problem.

Recall repair refund request. The engine coolant light had come on along with the heater not blowing hot air. The consumer had initially gone to master lube who informed the consumer that the intake manifold was malfunctioning and needed to be replaced. The consumer was also informed about a recall. The consumer was told that they would not be able to perform the recall for free because the vehicle was purchased used.

Second notice posted: Ince 2002: Replaced rotors, too thin when car was manufactured. (no recall ever done). Cooling system: Although the manifold gasket has been replaced, the water reservoir cap has been replaced, the radiator flushed repeatedly, entire cooling system bleed (to remove any excess air from radiator), serpentine belt replaced, all fuses, including the ac relay fuse/switch, all sensors replaced, and various mechanics have checked the entire car bumper-to-bumper, it continues to leak antifreeze coolant by forcing the water out of the radiator into the reservoir and out through the overflow tub (small tube located on reservoir tank). Excess pressure building up in the system. Leaking antifreeze once car is stopped. I have to refill the tank at least once a week. This problem (the Pontiac Grand Am leaking coolant) is a common problem with all Pontiac Grand Am. Recall to some component of cooling system is dire overdue! this car is an oil change every three months, regardless of 3000 miles or not, still out of the blue, the lifters are knocking and the belt is making a very high pitched screeching sound. Believed tension pulley needs replacing, with a possibility that all other pulleys need replacing. Its not the belt; the belt has been considered by three different mechanics has been "basically new". also, although it has only happened three times in the last several months, the engine has stalled. When this originally happened I changed the grade of gasoline I put in the car from 87 grade to 89 grade. Didn't help. (number of failures: For coolant leaks: Infinite).

I have a 99 Pontiac Grand Am and my wife has a 99 Chevy lumina. The lumina started to have trouble running, hesitating, and going through anti-freeze (1 gallon) weekly! I took her car to a garage and they replaced the intake manifold gaskets at a cost of $800. Her car only has 60,000 miles on it! the anti-freeze also gelled up and had to be flushed. When I picked her car up the mechanic laughed and told me that a 99 Grand Am just came in with the same problem! he knew I had a 99 Grand Am and told me to check it. I just checked it today and there is anti-freeze in the oil, and all over the engine. I had to fill the anti-freeze (about a half a gallon) and replace the oil before I can take it to the garage. What really angers me is that my car only has 45,000 miles on it!! what can be done about it?

Low coolant light came on I had just had the car service 2 weeks before and the intake gasket is leaking just got the car from a used dealer on Feb 20, 2004. Is there a recall on this problem. When I bought the car the dealer said it was normal for the temperature gauge to be at 200 I did not think that was right" now it looks like I have oil in my coolant could that be"

The heater control won't work at speed 1 and 2. the paint on the window frame is falling away. The rear struts failed. The transmission completely stopped working at all with no prior warning. The car doesn't heat up fully when it gets under 20 degress temperature. The rotors warp too quickly.

In August of 2001 when I purchased this car I felt a rattle on my brakes which is still there. My power windows are scratched from rolling up and down. Paint around the spoiler and bumper and on the roof is chiped off. I had to replace the generator in 2002. I had to have the intake manifold seals replaced in 2002. (3.4L V6) I had to have the waterpump replaced in spring of 2003. Now the head gaskets are broken the intake manifold seals again are broken. My transmission is no longer working. In other words I can not drive my car anymore; it is sitting my garage. The cost amounts to more than the car is worth in dollars and I still owe $9.500 on this car.
