The plastic pice holding the throttle lines snapped off and my cable went under my bracket and it took off I destroyed the Transmission putting it in neutral to stop the vehicle after I had gotten it stoped the fire from the engine was small I will recommend this car and yes I do want another one but it is a common issue I will recomed this car because the body is made out of steel and they are basicly tanks with the 3800 Series II and it was easy for me to spot what was happening and get ahead of it before it got worse I drove 5 miles with this happening before the engine overheated and caught fire

I started my car in the morning, per my usual routine. After a few seconds, I heard a very loud bang and the car stalled. A few seconds later, there was a large amount of smoke coming from under the hood. I opened the hood to see a large fire had started. My son, who heard the loud bang, came outside and saw the flames from under the hood. He ran into the house, grabbed a fire extinguisher, and attempted to put out the fire. He got the fire out but it was difficult. I had the car looked at by a mechanic and told me that the intake manifold had literally exploded. He has stated that he has never seen anything like this. It appears that the exploding manifold ruptured a fuel line. He told me there was a recall on this vehicle relating to a rupturing manifold and leaking fuel but that my vehicle had already had the recall performed. He thought that the new parts may be defective which is why I am reporting this incident.

This Preliminary Information communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester  and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.

This Preliminary Information communication provides information to the technician about vehicles that the Heater-Vent-Air Conditioning blows warm air. Before calling General Motors Technical Assistance Center technician will need to have high and low pressures, outside temperature, humidity, and vent temperature.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

This service bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.
