Review of the 2003 Chevrolet Impala

  • It might be called the Impala, but this disappointing front-wheel-drive family sedan has little in common with the V8-powered rear-wheel drive models of the past. Skip it in favor of the more refined offerings from Ford, Chrysler and Toyota.

  • Safety
  • Pros

    Six-passenger seating availability, good crash test scores, torquey V6 engines.

  • Cons

    Vague steering, soggy suspension, low-buck interior.

11 years and still going

Vehicle: 2003 Chevrolet Impala LS 4dr Sedan (3.8L 6cyl 4A)

I have had this car since new almost 11 years ago. I have not replaced any major components on this car in over 300,000 km. I have the full original exhaust system. In the past 20,00 km I replaced the wheel bearings and CV shaft. The car still runs like new. I have put paint on the hood and trunk to correct rust but then this car has never seen wax. I had a 93 Lumina and a (8 Lumina before this. In total the 3 chevs have gone a million km. I guess Ill buy another Impala. My son is looking forward to taking this car. Pretty dependable as well as economical.

Over all it's been a

Vehicle: 2003 Chevrolet Impala 4dr Sedan (3.4L 6cyl 4A)

I bought this car with 40,000 miles on it. Around 70,000 miles I had to replace my intake manifold gasket. I took it to a mechanic, not the dealership. He installed a quality after market gasket. I had brake rotor issues with this car until I did the brakes myself. I replaced the rotors with quality after market. The wheel lugs need to be torqued to proper specs, this will prolong rotor life. You need to flush and fill the radiator every 1 or 2 years despite dexcool specs. I keep it very clean. This car requires regular oil changes and cooling flushes. Synthetic oil and regular cooling flushes will keep it going. By using synthetic oil you don't need to change every 3K. Let the sensor work.

Overall a good buy

Vehicle: 2003 Chevrolet Impala LS 4dr Sedan (3.8L 6cyl 4A)

Bought my 2003 Impala LS second hand with 93,000 miles for my first car. Ran great for a good while but just had to get the catalytic converter replaced at 102,000 miles, Brake Controller Module Replaced, and my Idle Control Valve replaced, costing me all together $1,200. Despite those issues I've had no other issues I love my car. It rides real smooth and has some nice power. Has great gas mileage on the highway. This is really the last stylish model before the new Impalas went out. The interior is very nice and there is plenty of room for 5 people to fit comfortably inside. Currently at 104,500 miles and the car is still running great!
