I have just purchased a 2001 impala from dealer less than a week ago (4/29/2005) and I took it to the dealer today for some maintenance. The dealer told me the intake manifold is leaking antifreeze into the engine and it is quite serious. I have checked some online discussion groups and there seems to be a lot of complaints on this issue. It seems like this is a common problem on the impalas. I think gm should issue a recall for this issue and reimburse my cost of repair.
The low coolant light stays on indicating that the engine could over heat. Consumer checked the engine and found that there was a fluid leak out the engine. As a result the consumer has to put in coolant about once a month to avoid overheating.*ak dealer put new gasket in at intake manifold and repaired radiator. *bf

Our low coolant light came on, then my engine light came on we took it to get it service at first the dealership did a leak infection and found nothing to be wrong with the car they reset the engine light but my low coolant light kept coming back on the needle on the dash board hardly moves,then we brought it back and they said they found coolant leak at intake manifold gasket they also replace a tapping noise (which occured on our way to the dealership) which was caused by the lifters along with a brake check/pad replacement our bill total was $1504 out of pocket because our warranty expired already. I have been reading the internet and found an info regarding this leakeage on manifold is caused by dexcool which what they use in my car,I found out that the chemical doesn't contain an agent to fight rust but contains some acid chemical instead, do not quote me but go to website type dexcool and you'll see it.

(1) cooling system failure, temp gauge not working, check engine light, cooling fans running continuously (2) improper engine operation, roadside stoppage (3) reset connection on coolant sensor , system returned to normal operation.

The intake manifold/gasket on this vehicle has to be replaced. Car was overheating when idle. No heat was being generated. Cost to repair has been quoted as $580. This is a known problem on these vehicles, gm needs to issue a recall as any knowledgeable mechanic is aware of this very common problem, due to poor-quality intake manifold/gaskets being used on these vehicles.
I have two gm cars both 2001 my grand am I just changed the manifold gaskets and the head gaskets, now my impala also needs the same gaskets changed maybe there is a reason for this defect. I do not think that it possible to change these gaskets after four years. My grand am was covered my impala is not. What happens in the next four years? Please respond.
Have a chevrolet impala with a intake gasket leak. It is so bad it makes my young children physically sick. The turn signals have decided to only work once in a while and the locks on the doors (ours is a 4 door) are sticking - trapping us inside or keeping us locked out. Our trunk wont open at all!

Complaint received via e-mail."I would like to report what I consider to be a defective and potential fire hazard on my truck. The catalytic converter failed and the egr valve returned hot gases into the intake manifold. The hot gases burned a hole in the plastic intake manifold and melted the wiring harness. This could of caused a fire in the engine compartment. The engine stopped working properly and the vehicle had to be towed to the garage. My local garage replaced the intake manifold. The engine was still not running properly. I had my local garage take the car to our chevrolet garage. They found the problem with the converter and replaced it under federal warranty. I reported this to gm. Both garage agreed that this was caused due to the failure of the manifold. I believe the plastic manifold should be recalled as a safety factor." *jb
Manifold and pump gasket leaked. *nm the low coolant light came on. *tc
Purchase - may 2003 transmission - may 2003 transmission (electrical wire) october 2003 the car continued to run irregular.

September 2004 - catalytic converter october 2004 - undiagnosed due to chevy's refusal to diagnosis the car for free after just replacing the catalytic converter six (6) days ago.

Traction control light is lit when car is put in reverse.. There is no wheel spin when this happens.

Low coolant sensor has failed (4) times (beginning with the first at 35,800 miles). Dealership has flushed coolant system and replaced the sensor on each occasion. Each sensor has failed at about 20,000 mile span. Currently on fourth sensor which has failed on 5-27-04.
2001 chevrolet impala purchased new. Had to replace lower intake manifold gaskets at 48,000. Warranty expires at 36,000. This appears to be a common problem for this particular engine. 3400 v6. Dealer offers no recall. Consumer must pay the price.
While driving at 35 MPH vehicle caught on fire, heavy smoke came under the hood. Vehicle was taken to independent shop, technician determined that intake manifold caught on fire.
Coolant leak around thermoplastic intake manifold. This coolant leak developed around 42000 mi and is a design flaw that the dealer admits. Also dex-cool is falsley advertised that it can go 150,000 or 5 years. Most consumers aren't aware that it turns acidic and destroys gaskets and other cooling system components. I feel the coolant leak and associated dex-cool problems demonstrates gm failure to correct a known defect. Unfortunatley the consumer pays dearly right as warranty expires. Gm should replace thermoplastic intake manifold with something more durable and heat resistant.
When the heating system was turned on there was a strong anti freeze odor within the cabin. The odor caused a burning irritation in the eyes and nose. This was caused by the heater core leaking anti freeze into the cabin of the vehicle onto the driver's side floor.*ak
