2003 Chevrolet Impala - Electric Vehicle Guide
The 2003 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. The 2003 sits mid-run, with both earlier (2000) and later (2004) Impala model years also documented.
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 13 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 (194), exterior lighting (74), engine and engine cooling (58). A representative report reads: "My car sometimes cuts off while driving. Was on highway 301 running about 60 mph in the middle lane and just lost power no warning. No code no nothing. Sacred..."
