Recently purchased this vehicle 3 months ago took it in for a routine oil change after driving it for several miles and filling the gas tank loud exhaust sound with an onstar diagnostic p0151 code appeared. Thinking there was water in the line I purchased heat to remove the moisture with no results. I proceeded to open the hood of the car for inspection and found the oxygen sensors lying in the cooling fans and the catalytic converter disconnected from the engine block. The plate was still connected with new nuts and bolts but the part looked rusted which seem odd for a car this new as a result of the heat escaping the engine block via the opening the cooling fans melted. I check for recalls on this model and there were none showing via several sources including the manufacturer's web site. The issue could have caused severe damage to the engine and electrical systems well due to the high temperatures from the engine block under the hood of the vehicle. The vehicle will operate and drive in this condition showing a check engine light on the instrument panel. What seemed odd was the bolts were shiny and the plate was discolored as seen in attached photos. The welds were also a concern as well.

2003 Chevrolet Impala 3. 4l is difficult to start, replaced many parts to try and fix: fuel filter, fuel pump, spark plugs and wires, oxygen sensors, fuel evap valve, and throttle control. Vehicle currently has 52,xxx miles. Security light flashes, was able to pull error code p1626: theft deterrent fuel enable signal not received. Keys are original to car, I have tried to re-learn keys to vehicle with no success. Numerous repairs are listed under this error code, including the replacement of the bcm, and this doesn't always fix the problem. This issue needs to be researched further.

In less than one year the vehicle's catalytic converter converter had to be replaced. The oxygen sensor may have been the caused of the failure. The driver's information center stoppedworking, the passenger side window shattered and the oxygen sensor needs to be checked again.
