2004 Chevrolet Impala - Electric Vehicle Guide
The 2004 Chevrolet Impala belongs to a Chevrolet Impala lineup that Know Your Ride tracks across 5 model years, from 2000 to 2004. It is an all-electric vehicle, so it skips the oil changes, spark plugs and exhaust-system service of a combustion Impala entirely. It is configured as front-wheel drive with an automatic 4-spd. This 2004 car is the most recent Chevrolet Impala model year on record.
The high-voltage battery is covered for 8 years or 100,000 miles, separate from the bumper-to-bumper warranty. Routine upkeep centers on tire rotation, DOT 3 brake fluid, Dex-Cool battery/cabin coolant, cabin air filters and brake service rather than engine oil. Know Your Ride lists 15 scheduled maintenance items for this vehicle, the earliest interval falling at 7,500 miles. Documented torque values include lug nut 100 ft-lb.
NHTSA complaints for this vehicle cluster around electrical system (555), exterior lighting (70), engine (43). A representative report reads: "Cars acceleration causes me to be unable to pick up speed it decelerates up hills small or latg ramps cats constantly fly pass to avoid a multi car pile up..."
