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.

  • What's New for 2003

    There are only minor upgrades in store for the 2003 Impala. New options include a side airbag for the driver and XM Satellite Radio. Remote keyless entry is now standard and four new exterior colors are available. Both base and LS models get new wheel designs.

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.

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

I originally wrote a review in 9/2006 shortly after purchasing the car pre-owned. As we approach the sixth anniversary of purchase, we are delighted to report that this has been the best sedan we have owned! In our entire ownership, we have replaced a relay fuse ($50), a manifold gasket ($300) and a wheel bearing ($225). We finally replaced the original tires and breaks a little more than a year ago. Speaking of tires, my earlier review spoke of front end road noise. This disappeared with new tires. The car was originally equipped with cheap Uniroyals. The car still looks great, and runs and runs and runs! It replaced a Nissan which we purchased new & was totally unreliable.




Buyer beware

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

Bought my 2003 impala from a reputable dealer with only 41000 miles on it. Originally bought for my wife as a family car, but it has been so unreliable that she won't drive it anymore. It has been absolute trouble since I bought it. First the intake manifold gasket went. Then, the electronics stopped working properly. No signal, no heat control, no air control. All failed at different times. Then the front end started having problems. Tie Rods, Rotors, and now finally today, the steering rack. Completely failed going down the road. Could not power steer at all. I have always been a chevy man, and have lived with typical chevty problems; but no more. This is my last car from them.

Love my impala!

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

I researched a lot before purchasing the impala, comparing to Dodge Intrepid and Nissan Maxima. Loved the impala because was midsized car and could fit 6 people comfortably. Including an adult male in backseat comfortably. Also a great price with great mileage per gallon. Perfect car for starting family and working a distance from home.




Solid car

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

Given that this was a Chevy, I didn't expect much in the way of reliability. However, I have been very surprised! This is a good and very reliable car. I currently have 133,000 miles on it and it is still going strong. The only real disappointment was that the transmission was replaced at about 105,000 miles. The front brake rotors also warp easily, but those are easy to replace when replacing the pads. The engine still does not burn or leak a drop of oil.

Car is junk

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

Bought car second hand, still under warranty.It refuses to start (won't turn over) about twice per month (passlock issue). Very very annoying. Have to wait 15 minutes, flick door locks, and car will start. Head gaskets failed at 40,000 miles. Rocker arm stud pulled out of head a year ago, just happened again last week. GM used weak aluminum heads. The steering clunks, another GM defect. Body control module has been replaced twice. Lots of other problems as well. Last GM car for me.
