Manifold/header/muffler/tail Pipe problems of the 1999 Chevrolet Malibu - part 1

1999 Chevrolet Malibu upper and lower manifold gaskets replaced. Consumer believes there should be a class action suit for this problem. Consumer would like to know how to get reimbursed. The dex-cool coolant corrodes all parts of the engine it comes in contact with including the upper and lower intake manifold gaskets.

The contact owns a 1999 Chevrolet Malibu. While driving 30 mph the engine coolant indicator light illuminated on the dashboard. The contact took the vehicle to a mechanic, who stated that the intake manifold gasket failed, allowing the coolant to flow into the engine. The current and failure mileages were 54,300.

: the contact stated the low coolant light illuminated. The dealership determined antifreeze was leaking into the engine and replaced the intake manifold gasket. Three years later, the vehicle had the same problem and the dealership replaced the same component.

The contact stated the coolant light illuminated. He checked the coolant and it was low due to a leak from the intake manifold gaskets. He contacted the manufacturer. Repairs will be made at the consumers expense. Updated 01/11/06.

Coolant leaking. Have refilled several times. Took to car x, told me intake manifold gasket is leaking, has not failed but all engines of this type fail at some point. Is a known problem. Checking internet, that seems to be the case. Has not been repaired yet because of time involved and money ($600). Would like to see the part recalled.

I have had dex cool anti-freeze leaking from intake gasket manifold, causing engine damage. I have heard that the problem is caused by the dex-cool attacking the gasket and deteriorating it.

Consumer complained about an intake manifold gasket problem. It was leaking. Owner contacted the dealer and the manufacturer. Owner was told that it was common for this to break after 60,000 miles. When the consumer purchased the vehicle the mechanic told him the intake gasket was defective. The engine was leaking coolant.

I first noticed the low antifreeze light came on after the car was sitting for over 6 hours. After stopping to see what was wrong, the light went off. After getting home, I looked at the engine and noticed a collection of antifreeze pooling on the engine, and much sludge collected on the engine. I refilled the antifreeze reservoir and took the car into bob montgomery Chevrolet, louisvile, kentucky. They indicated that the intake manifold gasket needs replacement, which is what I figured after doing some research online. Apparently, this problem has been reported before by over 1100 car owners, and is a design flaw with this particular engine. Moreover, some research indicates that the design has not been corrected, and therefore can be expected to reoccur. My problem first occurred during the first week I owned the car, fall of 2000. This incident was repaired under warranty by uebelor Chevrolet, jasper, indiana, and has not recurred until now. This complaint should be added to the large group that came before it.

Vehicle was taken to dealer for regular maintenance, and results showed that the intake manifold was leaking fluid, which could cause it to overheat. Manufacturer will be contacted by consumer.

The intake manifold has been replaced 2 times on this car. We are still having engine cooling problems. It is in the shop as we speak. Now they are looking at the head gaskets due to coolant leaking into the overflow. There has been numerous complaints I have found in regards to this model. Why isn't anyone contacting the chevy to get this design flaw corrected and compensation for the affected consumers who were unfortunate enough to buy this particular model?.

Engine coolant light came on. Took car in to get checked while having oil change and was told that there was a coolant leak in both the upper and lower intake manifolds.

I have contacted GMC Chevrolet division via their customer service line to no avail. I have several pages of documentation that supports the vehicle I drive(1999 Malibu) is one that chevy should be ashamed to attribute to the "made in America" caqmpaign. I have had to replace on seven occasions the rear stop/tail lights. The bulbs burst, they simply stop and as of 08/14/04 I have replaced yet another set of bulbs except this time the lights failed to work at all. The worker at napa auto store in riverdale georgia even checked the fuses and found no fuse blown; he even showed me the fuses as he pulled them. Additonally I have had to replace the intake manifold gasket and the heag gasket;this is a common problem with these vehicles and there is a technology bulletin from gm that supports the intake mainifold gasket was/iis faulty because of the material it is made from on this vehicle on several gm mid-size vehicles. The dexcool product turns to sludge and thereby creates a leak. I read in the atlanta journal constitution that your agency's intervention has prompted gm to recall the Chevrolet Malibus from 200-202 (?) to correct the rear light problem and the article stated consideration was being given to extending the recall to the 1999 model for the same problem( rear light). I really need to find out the status of this attempt becasue I currently am unable to drive at night because I will be ticketed.

Anti-freeze is leaking from intake manifold gasket causing engine damage. I have heard that the problem is caused by dex-cool anti-freze. This new type of anti-freeze attacks the gasket material. The cause could also be inferior gasket material specified by gm.

Intake gasket was leaking coolant, and the engine was running hot. Consumer had to check it everyday. Also, had to add coolant.

I had frequent loss of coolant, and drips on my driveway surface. Upon taking to dealer I was informed that intake gasket leaking. Also I was told brakes were almost gone. At 53,000 miles this seemed excessive on both counts. The replacement of the intake gasket was about $700. 00. Replacing the pads and turning rotors cost $250. 00. This makes the 3rd set of pads, and resurfacing of the second set of rotors since I bought the car new. Shortly after the repairs the abs light started coming on whenever making a turn. Brought the car into the dealer in may and was told that the front wheel bearing assy needed to be replaced. I was also told that this occurance had nothing to do with the recent brake job, even though there were no problems until I had the brake job done at their recommendation. The dealer, while acknowleding no blame paid 50% of the repair leaving me with a $200. 00 bill. In little more that 30 days I have spent $1200 on critical part repairs for a well maintained car with only 53000 miles.

Intake manifold gasket leak. Replacement costing $613. 00.

Intake manifold gasket failing at 50,000 miles.

Coolant leak from the intake manifold gaskets and related parts.

On 8/20/2001 at 46,208 miles on my 1999 chev. Malibu, coolant began to leak from the lower intake manifold gasket. Dealership replaced gaskets under gmpp extended warranty. Now on 3/12/04 at 75,600 miles, the replaced gaskets are leaking. After the first repair, I discovered that the original factory gaskets along with dex-cool coolant were defective. At the first repair, still defective gaskets were used to make the repair. After this first repair, gm released a newly redesigned gasket and procedure to address this issue. I feel that there needs to be a recall on the issue due to the number of consumers who are experiencing this same trouble. This could become a safety issue should the gaskets completely fail and allow coolant to mix with the oil. This would cause engine failure while driving, possible resulting in a crash.

Plastic lower intake manifold gasket replaced under warranty @ 28,000 miles, and it needs to be done again @ 78,000 miles for a cost of $800. 00.

I myself, had to have my intake manifold gasket replaced in my 1999 Chevrolet Malibu. It was recalled on certain VIN numbers, but not mine. A friend of mine also owns this same make and model of the Chevrolet Malibu and she is currently having to have the same problem fixed. I am experiences several problems with my vehicle that I saw on a recall list for a particular set of vins. I find this to be a bit strange that I am currently having these manufacture defects, as well as others that own this make and model of this vehicle, and they are only recalling a select few. It seems strange that 3 people I know experience the same problems with this vehicle, yet, there is no recall on them.

Intake manifold gasket was defective-causing problems with stalling and ignition among others. Car has stalled three times while in motion. Chevy cannot replicate the problem. Left me sit twice because it would not restart-eventually would restart after engine cooled. Still runs terrible after some type of maintanence was completed on the car which chevy believes would fix the problem. Has become an unreliable car and I am fearful of driving it due to the ignition stalling problems. Chevy not really helpful in dealing with the situation.

Intake manifold gasket leaking coolant after only 25,000 miles. Numerous other complaints regarding this issue. All gm mechanics know about this issue but gm will not take responsiblity for this design flaw.

Lower intake manifold gasket leaking.

My auto over heats. Coolant leaks around the intake manifold gaskets near the heat sensor. I have to add coolant at least once a week. My auto is a 1999 Chevrolet Malibu four door sedan,VIN #1g1ne52mxxy111437. I didn't recognize this problem for what it really was until warranty expired. High gas consumption. Only 71,000 miles. Town driven by lady. Dealer says this common problem with car.

The intake manifold gasket fails. The dexcool coolant leaked into the oil. The bearings on the gasket are damaged. I was told that I really need a new engine, but that I could try replacing the gasket, but there are no guarantee that will work. I understand this is a common problem for most gm cars from that time frame and starting around 40,000 and that gm has even made a new part finding the original deficient.

Engine coolant leakage - warped lower intake manifold gasket causing engine coolant leakage and boil over. This is apparently a frequently occurring problem with general motors v-6 3100cc engines.

I am writing to find out the frequency of complaints regarding the Chevrolet Malibu I have a 1999 year and had problem with intake manifold that had to be repaired for $700(antifreeze would leak into engine) I was told by sources that this was a common problem with this model including gm mechanics themselves and that it should be a recall. Any help would be appreciated in how to proceed with gathering information on this and what you know about it.

I had my manifold intake gasket replaced and I know that gmac had a technical bulletin issued on it. I contacted gmac and they advised they would not pay for it. A couple months later my car started to make noise so I took it back where I got it fixed at and was advised I need a new engine. I contacted gmac and they didn't respond until December 24, 2002 and told me they wouldn't pay for the engine since I didn't get my car repaired at a gmac dealership. I told them when I took it to the Chevrolet dealer they said I couldn't get my car in until the following week and I couldn't wait that long because I needed my vehicle so I took it to another shop. Had I been told when I first called gmac I would have tried to take it to another Chevrolet shop. I am paying for a car that I can't even drive and the vehicle is only 3 years old. Please advise as to what I can do to have this matter resolved.

3/18/03 - Malibu is diagnosed with an intake manifold gasket failure. The vehicle was losing coolant, but there was never any signs of leakage on the driveway. An independant shop diagnosed the problem. A little research on the internet revealed that very many other gm owners were experiencing the same problem. We attempted to get assistance in paying for the repair from gm, but they refused. The design of the gasket system combined with dexcool coolant appears to be faulty. We also have a cronic problem with the braking system on this vehicle. About every 12000 miles the brakes need to be replaced, the rotors are warped and the pads are bad. So far, gm is picking up all those costs because the problem was reported while it was still under warranty. Through the internet we also discovered that many Malibu owners have the same problem.

While traveling on highway and without prior warning brakes went out. Master cylinder broke/ intake gasket failed, and oil and coolant had mixed together.

I have a 1999 chev Malibu and yes the intake manifold is failing. I have had this replaced by the dealer twice. Gm apparently knows about this problem for using shotty parts and they refuse to step up and fix it. I am formally complaining to the bbb gm itself and anyone else I can think of. Gm chevy stands for junk.

Manifold gasket replaced on 1999 Chevrolet Malibu that I paid for and gm has not even got back with me yet after I sent them copies of all my bills. This problem never should have happened and now I see a service bulletin on it and have a 2002 impala that they want to put sealer in instead of fixing the gasket. I think they owe me money for the Malibu and they need to replace the gasket on the impala.

The intake manifold gasket cracked, and caused coolant to leak onto the engine. The vehicle needed coolant about one year ago. The consumer added coolant in the beginning of 06/03 at approximately 37,500k miles and again one month later at 38,500k mile. Several mechanics said they had seen a lot of these problems around 40k miles.
