On 2/24/14 at approximately 2:50 pm, I properly attached a set of battery jumper cables from my truck to this car to start it from a dead battery situation. When the owner attempted to crank the car, there was an explosion from the intake manifold during the cranking, resulting in an explosion and small fire. The owner immediately switched the car off, and exited the vehicle, and I immediately closed the hood so that the fire would not spread, called the fire department, and removed the vehicles around it. The fire dept. Responded within 5 min. , and extinguished the fire with water. The fire dept. And police inspected the car, and left after it was determined that the fire was properly extinguished, and there was no further risk of the fire re-starting. The fire damage was confined to the entire under-hood area of the car. When the explosion happened, the engine cover and oil filler cap was blown approximately 5 ft. From the car, the intake manifold was blown open, and the fire was burning inside the intake manifold. We attempted to push the car into the parking space, but it would not move. It seemed the engine had seized, probably as a result of the fire. The car has since been towed to our mechanic. The car's owner was inside of the car, attempting to start it via the ignition key. I asked her if there were any prior issues with the car, and she told me that at the time, other than a flat tire and dead battery, the a/c was inoperative, and not being used. Approximately 2-3 years ago, the car was brought to a local dealer, and a recall issue was performed on it. She did not remember what service and recall repairs were done on the car. Prior to this incident, the car had not been operated for approximately 2 weeks. I am the person most able to give the details of the incident. The owner of the car (sister) has authorized me to act on her behalf in this matter.

23 Manifold/header/muffler/tail Pipe problem

Failure Date: 09/01/2012

The chevy Impala had a loss of coolant even though there is no leak on the ground. After research online, I found the following: "the 3. 8-liter v6 may leak coolant into the engine from the intake manifold. A new gasket kit, revised throttle body nuts, and sealing compound is needed. " due to the number of complaints found online pertaining to this issue, this should be a recall for this model car.

24 Manifold/header/muffler/tail Pipe problem

Failure Date: 01/31/2012

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?.

Failure Date: 07/18/2008

Intake manifold gasket failure, engine coolant light will come on which is prelude that coolant is leaking into the oil. Most all people will not even know this. Gm used a plastic gasket and if you check with any repair shop/gm service garage they will all tell you the same, the plastic gasket just deteriorates, with any mileage from 60k to 90k and the cost to repair is from $795 to $995 plus tax and garage surcharges ie some charge clean up and add ons such as cost of towels and cleaners etc. I was told by several repair professionals this is such a common problem they know as soon as a Impala rolls through the door, exactly what it is. ""I believe gm should take ownership for using a defective part as no other vehicles have such poor failure rate, nor have I ever in my 58 years of live and ownership of 15 cars/trucks ever had to replace an intake manifold gasket because of deterioration. Just search the internet and you will find a million people of the same issue. If they knew where to complain, I am sure you would be swamped. I hope something can be done to help all of the owners. Thank you for your time and assistance.

Failure Date: 08/03/2006

2000 Chevrolet Impala LS, 3. 8 engine. At 78,000 miles the "lower intake manifold gasket" failed causing loss of coolant. Required $804 repair. My research indicates this is a widespread pattern failure of gm 3. 8 liter engines of that year, due to insufficient torque on the intake manifold bolts and/or a faulty gasket. This affects other gm brands using the same engine. A properly maintained engine should not suffer this type of failure at 78k miles.

34 Manifold/header/muffler/tail Pipe problem

Failure Date: 07/25/2004

"plastic" by pass tube from intake manifold to water pump cracked, causing antifreeze to leak out at a rapid amount. Can't believe that the tube is made out of plastic since it is in contact with the intake manifold which is very hot. Fortunately my wife and son were just around the corner from our house and not on the trip to ohio which was planned. Only going about 10 mph when noticed a gurgling sound. Got out of car and saw fluid leaking. Came back to house and I checked it out and found that the plastic tube above the water pump leading into the manifold was indeed the problem. Took car to Chevrolet dealership. They replaced the by pass tube at a hefty cost of $262. 38.
