Manifold/header/muffler/tail Pipe problems of the 1999 Oldsmobile Alero

Car began to overheat two days ago. Intake manifold gasket replaced a year ago. Dealership stated the intake manifold needs to be replaced again. We also found out that we may have a blown head gasket and possibly a cracked engine--which means a new motor. Car has 80,000 miles on it and has been very well taken care of. We are devastated as this is our daughter's car and she is about to be a freshman in college. The car broke down on her while traveling down an interstate-at night.

1999 olds Alero 70,000 miles and will have to spend over 700 replacing the intake manifold gasket. If we do not repair, will lose engine at over 2500 expense. We have talked to shops and read internet issues predominant on this same issue. Gm should do a recall on this vehicle due to so many complaints on this issue.

In March 2006 at 73,277 miles I had to have the intake manifold gaskets, valve cover gaskets & water pump assembly replaced due to a constant antifreeze leak. Then in April 2007 at 87,452 miles had to have the head gasket replaced due to the same problem. Was told by the mechanic this was a common problem & gm even changed the intake manifold so the one I had put on in 2007 was different than the one in 2006 because they have had so many problems. Seemed like they should be reimbursing people & having a recall because they obviously knew about the problem.

1999 olds. Alero 3400 GLS. There is a problem with the manifold gasket many people have this problem I think it should be looked into for a safety recall.

Discovered during a vehicle inspection that oil was leaking around the upper part of the engine. . . Near the head and intake manifold area. Plus have been smelling burning oil through the ventilation system. . . Occasionally. At the time, vehicle was no longer under manufacture warranty. . . Contact manufacture for assistance, but assistance was denied.

Engine coolant leak onto engine block and transmission housing. Intake manifold gasket needed to be replaced. Oldsmobile dealership stated that this was a common problem with the 3400 v6 engine.

My car's coolant light came on the first time about 2 weeks ago. At that time I replaced the coolant that was missing, only to have the light come on again 2 days later. I again replaced the coolant. I could not find any visible leaks under the car. I was driving to the mechanic when my check engine light came on, and the check coolant light came on. The cars tempature gauge was topped out. I had to pull over to the side of a major freeway and call for help. After 2 hours of waiting for a tow truck. The mechanic tells me that the upper and lower intake manifold gaskets need replaced. Also, the coolant had leaked into my engine and mixed with the oil causing the engine to miss. I had to have the gaskets replaced with a new version. And also have the engine flushed, an oil change and a coolant flush as well as a coolant change. All of this costing well over $700. Apparently, gm has issued a service bulletin related to this issue but has failed to issue a recall on that particular part. My safety should be of some concern to this car manufactuer to say the least!.

A leak in the intake manifold that is allowing coolant and oil to leak into the engine. It costs between $600 - $800 to repair and this is a faulty part in a majority of the gm vehicles. There was a service bulletin dated March 2003 that entails the exact details of the problem, yet gm has not offered its customers any remedies to the problem such as paying for the repair. I have maintained this vehicle with all required service work. I want gm to pay for the repair.

1999 Alero having problems with manifold leaking oil and failed fuel injectors. The front spring had broken suddenly as the vehicle was in motion. The manifold and injector problem occurred within one week. Recall #3v473000 and there was a recall for the suspension.

At 50k miles, low coolant light would flicker on and off so per the manual dexcool/water mixture was added. This alleviated the problem only temporarily however. Light continued to come on, and later at 61k, oil leak was noticed on the side of the intake manifold. An appointment was made to bring the car to the dealership the same week, during which the security dummy light came on (for no apparent reason). Also during this week, the "change oil" dummy light came on 100 miles before the oil change was due (at 2900 miles). The car was brought to the dealership to fix per its appointment, and not only was coolant leaking into the engine, but the upper and lower intake manifold gaskets required replacement. In addition, on its way to the dealership, the engine started to misfire causing the "check engine" light to flash for several moments before turning to a steadily lit dummy light. Car has always been given routine maintenance and oil changes every 3k or as necessary, so this performance and obvious design flaw are very disappointing. Would not recommend this car/3. 4l v6 engine to anyone looking to purchase a new vehicle and considering this make/model/engine type.

I bought my Alero in may of 2003, and it is not March 2004 and I am replacing the motor. Started out with brake problems, then went on to the leather under the windows and on the dash "bubbling" up in the sun. Next, I had coolant/oil leaks at the intake manifold. Low trac light came on all the time, low tire pressure light stays on, the fan for the a/c or heat only worked in the 3-5 positions. (it's full blast or nothing. ) coolant light frequently came on, transmission fluid vanishes, coolant leaks, yet no one knows where from. The temperature gauge never goes below halfway, and it ran hot a lot. Had to replace the coolant cap and overflow resevoir. The gas hand sticks, the speedometer sticks, the leather seats are tearing, had to replace the factory radio because it would not pick up any channels, rear defrost works only when it wants to, and service engine light stayed on about half the time. I took this car to 7 mechanics, had it hooked up to diagnostic computers, had everything checked-yet no one could tell me what was going on. Finally, I left the mechanic shop after being told that the car was "good to go" (which I would never put in the same sentence with Alero again. ), and it starting skipping. I had it towed, only to find out that I had a cracked block and cracked heads. (new motor needed-final prognosis) my mechanic told me that it would do absolutely no good to put a motor in it because in 2 years-the new motor will do the same! Oldsmobile should be ashamed that they would recall a glove box latch, yet not the motor. After reading the reviews that I have read in the past week, I am seeking legal action in regards to this issue. I did not pay $17,000 for a lemon, which is all I got!! don't buy!! buyer beware!!.

Head gasket and manifold gasket leak on a 1999 olds Alero with 55000 miles.

The check engine light came on. Upon checking the coolant levels, it was low. The repair shop diagnosis is a leak in the intake manifold with an $800+ repair cost. According to research, the particular type of coolant, dexcool, used in gm cars is linked to corrosion to the intake manifold gaskets.

Car overheated. Had to have it towed. Rear of intake manifold was found to be leaking. Intake manifold gaskets had to be replaced.

The "coolant" light came on - then the car died & overheated. . . Apparently coolant was leaking into the engine because a gasket failed. . . Now the engine must be replaced at 70,000 miles. Starting at 3,000 miles, the check engine soon light came on & it has been in and out of dealerships ever since!!! gm hasn't done a thing to help me! I just spent $1,300 to get the gasket replaced in the intake manifold & now they tell me the engine needs to be replaced!!! please help me - I need a contact for gm - the customer service line has not done a thing to help & apparently this is a common problem. . .

While driving driver noticed smoke coming under the hood. Pulled vehicle over and checked. Noticed coolant was leaking on the intake manifold. Took vehicle to dealership. Mechanic had not determine the cause of the leakage.

Due to gm defect to date I have had to replace intake manifold gasket, water pump, thermostat, serpentine belt and am now looking at replacing gas tank and heater core. .

Engine: 3. 4l v6. The manifold gasket and water pump failed at approximately 40,000 miles. The dealer picked up the cost of the parts under their "goodwill" policy, but out of pocket cost to me was still over $800. The manifold gasket on my 2002 Buick rendezvous, VIN 3g5da03e52s528965 also failed and had to be replaced at 18,000 miles. This was done under warranty at no cost to me. This was also the 3. 4l v6 engine. It is obvious this is a problem gm has known about for quite some time and have not taken corrective action in a timely manner. An extension of the warranty on this engine is certainly called for. I have advised many friends to avoid purchasing a gm car with either the 3. 1l or 3. 4l engine.

Water pump and intake manifold gasket had to be replaced at 40,000 miles. Very disappointing. Appears to be common problem with gm 3. 4l v6 engine. Reconsider before purchasing car with this engine.

Gm v6 intake mainfold leak.

I have a 1999 Oldsmobile Alero with a 3. 4l v6 engine that leaks coolant from the intake manifold gaskets. My dealer is jim muir Oldsmobile, who put me in contact with gm customer service. They claim no knowledge of the problem. According to the internet, there are thousands of vehicles with the problem. My father, who works at gm says that at least seven people he knows in his office have had repairs done. Gm needs to acknowledge the issue and start fixing them.

We purchased this car in July 2002 from classic Chevrolet in owasso, ok. We also purchased an extended warranty. In December the car was hit from the rear by a hit and run driver. In January the engine began to knock. I called the warranty place and got permission to take it to a mechanic, he said it was the intake manifold gasket, replaced it when it still knocked he said it would take awhile for all the water to get out of the engine. We took it back, and got a run around for 4 weeks, finally called the warranty place told them he wasn't getting it fixed and requested permission to take it to a different shop. Granted then when they found out it needed a new engine they refused to pay for it, said they would only contribute a sum of money toward fixing it. I called gmac because they financed the warranty, one person told me that gm should honor the warranty and so I have a call in to a dealer in pittsburgh, KS. We no longer have a gm dealer in our town. My point is that someone needs to make this right and put a new engine in my car at no more expense to me. When I talk to gm I will be letting them know that I found your site and checked it out, and lodged a complaint. I am unsure of the exact date of the incident and since it is 4:15am am unable to call and get it.
