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.

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.

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.

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.
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.
