2004 Chevrolet Impala Owner Comments

While applying the brakes for the first time after start up at low speeds (less than 20mph) the antilock brakes kick in when not needed. For about 2-3 seconds, there is extremely reduced braking ability. After this initial time period, the whole antilock braking system shuts down and also turns off the traction control system. Once the shutdown has taken place, the car's braking system functions as if there was no antilock brakes on the vehicle. Took car to dealership which indicated that the wheel sensor was bad and could be replaced for $600. Also while driving on the interstate, noticed that the speedometer was stuck at 65mph, regardless of speed. When turned off, the vehicle still read 65mph. Was unable to determine proper speed. Noticed that the vehicle reset the speed 5mph lower each time the ignition switch was moved from off to on. Multiple cycles of turning the ignition switch on and off finally reset the speedometer to 0mph. Don't know if this is only a temporary fix for a problem that will probably get worse. Although not a serious issue, the tachometer does the same thing.
