Does the "security" light come on? It may be an issue with the GM Passlock anti-theft system. There is tons of information on repairing the GM Passlock problems. Just search for "2003 Passlock issues."

SOURCE: 2003 chevy impala impala shakes when brakes applied
If it only happens when braking, then it is definately you brake system. Most likely you rotors and pads need replacement. If you can do car work, then this is not a difficult job, but requires some wrenches. The parts can be purchased a lot cheaper on-line. A shop will get you for $300-$800. I bought all my parts for my 2001 VW passat for $200 shipped to my door. Good Luck.
SOURCE: Where and how many o2 sensor's on a 2003 chevy impala?
There are two sets of 02 sensors on most cars today. On set is set directly behind the header, one on each side, if it is a V engine. This set is used for the engine's ECU to control timing as well as other variables. The other set is placed on a bung in your Catalytic converter. This 02 sensor is used for emissions purposes only.

I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.
