The contact owns a 2000 Chevrolet Impala. When the vehicle was started, a clunking sound was heard. The contact looked under the vehicle and noticed that a fire had erupted near the exhaust manifold. The fire extinguished on its own. Also, the vehicle intermittently misfired and performed sluggishly.

I went to start my 2000 Chevy Impala after sitting for 2 days in the cold. It would not start. We opened the engine to charge the battery. I tried to start the car one more time and it sounded like a bomb went off. Parts flew everywhere hitting everyone around the car. When we checked the engine we noticed the intake manifold exploded. This is extremely dangerous and we were lucky no one was hurt be flying intake parts.

Impala 6-cyl

  • 108,000 miles


Oil and coolant (anti-freeze) is evaporating or being burned up. After extensive research online, it seems there is a defect in the material used by Chevy with regard to a gasket called a plenum that is located in the intake manifold. The gasket warps under heat and age and allows coolant and or oil to enter the engine compartment which evaporates. With the amount of complaints I found online, this seems like a common issue with the Chevy Impala 3.8L V6 type 2 engine. GM should replace the inferior material used with a superior metal gasket. This issue seems like it could cause a fire in the engine. I also read that this issue can cause oil to be burned. GM used a cheap gasket to save money but this is a safety issue when coolant and oil is being burned up internally at an unusual speed of time. The second unknown issue is, will this cause a fire?

Impala 6-cyl

  • 118,259 miles
About weeks before the incident, my car seem to misfire. The car was parked for 3 days. When tried to start it, the engine exploded and caught fire. The intake manifold and motor oil cover and some other engine parts exploded out of car. When contacted GM and mentioned the incident, no action was taken by GM and the refuse to take any action or acknowledge any responsibility. It appears that same engine has issues which caused a recall on April 14, 2009. The symptoms/cause are described as: "GM recalled 1.5 million vehicles with this engine on April 14, 2009 due to risk of fire from engine oil leaking under the valve cover gaskets onto hot exhaust manifolds. The fire could spread to the nearby plastic spark plug wire retainers on the valve cover and then to the rest of the engine compartment. GM fitted the affected vehicles with redesigned spark plug wire retainers.[3] these engines were noted for having problems with the plastic upper intake manifold cracking around the egr passage. The engine would then vapor lock. " I did take my car to dealership to take care of this recall but it appears that it does not fix the problem and it still exists and my car is totaled. But GM has told me that according to Texas law it is not responsible for any issues after 4 years from the purchase date.

While driving this car it would just stall or die as if someone had reached over and shut the car off and would not start for a few days. I have brought this car to two mechanics and neither were able to stop the problem but told me that different parts were the culprit, so 800 dollars later I have replaced the fuel filter, fuel pump, crank shaft position sensor, mass air flow sensor, replaced the battery, tested the alternator, tested the fuel injectors both hot and cold, tested the ignition module and still the car died leaving my child and I stranded on the side of the freeway in cold temperatures. I then called a GM dealership whom said another $120 just to look at it and said they couldn't find the problem. This is outrageous!

Impala 6-cyl

  • 200,000 miles
My car (a 2000 Chevrolet Impala, 3.8L V6 engine) repeatedly died as I was driving or stalled. It became a huge safety issue, especially when I would be driving at high speeds on the freeway with nowhere to pull over. I took it in, but diagnostics showed nothing. I kept replacing parts, but to no avail. I felt unsafe driving anywhere and even got a bike so I wouldn't be facing near-death experiences every time I drove. Eventually I found a message board that suggested replacing the crankshaft position sensor. I just did and am hoping it works. Something needs to be done about this though, it's crazy to have to go years with a faulty car and no one can find a fix for it.

Safety recall 09047 for 2000 Chevrolet Impala. The consumer stated the reason for the oil seepage onto the exhaust manifold was due to the valve covers being made of plastic and it required frequent gasket changes, because the covers did not properly compress the gasket. The consumer stated the only effective remedy would be to replace the valve covers with metal ones, which would compress the gasket more evenly and prevent oil leakage onto the exhaust manifold.

Impala 6-cyl

  • 105,000 miles
The contact owns a 2000 Chevrolet Impala. The contact received a recall notice for NHTSA campaign id number 09V116000 (engine and engine cooling). The remedy stated that the dealer will remove the spark plug wire retention channel at the front of engine and install two new spark plug wire retainers for free. Oil has already begun leaking from the contact's vehicle; therefore, the remedy would be insufficient in correcting the failures. The manufacturer did not assist. The vehicle has not been repaired. The failure mileage was 105,000 and current mileage was 140,000. Updated 07/17/09 the consumer stated the recall was performed on June 25th. The consumer insisted that the technician tell him where the oil leak was coming from. The oil leak was coming from the front valve cover gasket, which was below the spark plug wires and spark plug wire retainers. The spark plug wire retainers that they replaced had no evidence of oil, therefore the leak was not related to the recall and did not pose a safety threat. Updated 07/21/09.

The contact owns a 2000 Chevrolet Impala. While the vehicle was parked in the garage, the contact heard a loud banging noise. She immediately noticed flames under the hood. The power windows and locks failed and trapped the contact in the vehicle momentarily. The fire spread to the side of the garage and caused minor property damage. The manufacturer would not assist with the repairs and only offered $1,000 towards the purchase of a new vehicle. She received a recall notice for NHTSA campaign id number 09V116000, which stated that if the manifold is hot enough and the oil runs below the heat shield, it may ignite into a small flame and spread to the plastic spark plug wire channel and beyond, increasing the risk of an engine compartment fire. A police report was filed. The failure and current mileages were unknown.
