Engine and engine cooling: exhaust system: manifold/header/muffler/tail pipe
- What is wrong
- General Motors LLC (GM) is recalling certain model year 1998-1999 Chevrolet Lumina and Oldsmobile Intrigue, 1997-2004 Buick Regal and Pontiac Grand Prix, 2000-2004 Chevrolet Impala, and 1998-2004 Chevrolet Monte Carlo vehicles. The affected vehicles were previously repaired under recalls 08V‑118, 09V‑116, and 15V‑201 to address the possibility that engine oil may drip onto the hot exhaust manifold.
- Risk
- Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.
- Remedy
- The remedy applied under recalls 08V‑118, 09V‑116, and 15V‑201 did not adequately remove the safety risk. Under the improved remedy, dealers will replace the engines front valve cover and gasket. Vehicles that are covered by recalls 08V‑118, 09V‑116, or 15V‑201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number. The recall began on February 19, 2016. Owners may contact Chevrolet customer service at 1‑800‑222‑1020, Buick customer service at 1‑800‑521‑7300, Oldsmobile customer service at 1‑800‑442‑6537 and Pontiac customer service at 1‑800‑458‑8006. GM's number for this recall is 15757. Note: Until the improved remedy has been applied, owners are advised to park their vehicle outside since the fire risk exists even when the vehicle is unattended.

Engine and engine cooling
- What is wrong
- General motors is recalling 1,497,516 my 1997-2003 buick regal, my 1998-2003 chevrolet lumina, monte carlo and impala, my 1998-1999 oldsmobile intrigue, my 1997-2003 pontiac grand prix vehicles equipped with a 3.8l v6 naturally aspirated engine. Some of these vehicles have a condition in which drops of engine oil may be deposited on the exhaust manifold through hard braking.
- Risk
- If the manifold is hot enough and the oil runs below the heat shield, it may ignite into a small flame and may spread to the plastic spark plug wire channel and beyond increasing the risk of an engine compartment fire.
- Remedy
- Dealers will replace the engines front valve cover and front-valve-cover gasket with new parts of an improved design and remove the engines plastic cover and plastic oil-fill-tube extension, free of charge. The recall is expected to begin during may 2016. Owners may contact chevrolet at 1‑800‑630‑2438, oldsmobile at 1‑800‑630‑6537, and pontiac at 1‑800‑620‑7668 or http://www.pontiac.com or http:www.gmownercenter.com.

Vehicle shuts off when moving,turning or stopped at a traffic light. By switching to neutral, the engine may start after 1 or more tries. So far the failures have been on city streets and highways. But not interstates. The failures are many but unpredictable.
Vehicle fire. Vehicle caught fire while cruising at highway speeds. Very dangerous. Vehicle is a total loss.
I just recently bought this vehicle 03/11/20 and it ran great till yesterday when the intake manifold exploded and caught fire to the engine from the fuel lines melted this happened when I was getting a jump. It says there are no recalls pending it is the 3.8l and it looked original all the parts did can you please help me out
The incident happened this morning as I was leaving for work. My car was parked in our driveway and had not been driven in 2 days. I got in the vehicle and put the key in the ignition and as soon as I turned it to start there was a loud bang that sounded like a gunshot which I thought was a backfire. The entire plastic intake manifold gasket had exploded into pieces and white smoke began to rise from under the hood. When I opened the hood and the smoke cleared I began to assess the issue, I noticed the manifold gasket cover had been blown completely off and the manifold itself was in pieces. I've done some research and this seems to be a common but uncommon thing among early 2000's gm vehicles.
The power steering return hose rubs against some part of the motor and rub a hole in power steering return house
The security system locks and will not let me start the vehicle every couple times the vehicle is started.
Recall id 240424 received this from credit karma. Currently our car is having overheating issues. Engine cooling issues,exhaust manifold/header/muffler/tailpipe, oil leaking on to my exhaust I'm afraid to drive it, afraid it may catch fire.
Coolant system has been an ongoing problem with the vehicle. After refilling coolant and oil, it was discovered that oil and coolant were dripping underneath the car. According to a gm representative, there are service bulletins out for this year make and model, but I've been told my VIN is not one of them. It has all the same symptoms described in other bulletins. I'm not sure how/why this VIN isn't included when the same symptoms exist.
