I have had my impala since 04 I bought it used with 60,000 miles on it. I have replaced the motor once, tranny once, and the power steering went 2 times and that was withing the first 2 years under the warrenty as well as the ABS and traction control sensors in the hubs are a pain they go every 2 years if not more often. Now after the warrenty is up I will say this thing has sucked more money out of me then if I had children! I find my self replacing the power steering pump constantly and the high presure line and the rack and pinion. The gas gauge doesnt work cause the level sensor in the sending unit is frozen and they want 300 for the whole unit cause you can't get just the level sensor.
I have owned my Impala 9 months. YOU can't find a better car for the MONEY! You can't find more ROOM in it's class. You can't find better GAS milage in it's class. You can't beat the PRICE. Luxury, Ride, Power, Handling, Room, Looks, What's not to like?
I have had my impala for 7 years now, with over 225000 miles, I still get 29 miles to the gallon average for all driving. I have only replaced the catalytic converter. It still has the same get up and go. It is wonderful on long trips. The only car I have ever owned that does not hurt my back after 12 hours of driving. I own three Chevy's all over 200000 miles, one over 300000 miles, if you want minimal repairs and a long lasting vehicle, Chevy's are your car, with Impala's leading the pack
I know many had problems with the 2000 - 2004 - engine cradle, brakes, windshield leak to mention a few. Traded mine in with 109,000 miles, slight hail damage, LOUD Front End Bearing Noise between 40 and 70, along with sensor failures. It just got old. It was a good car until the sensors started wear out. Got low 20 around town and upper 20's on the Interstate for gas mileage. Bladder full before gas gauge screams for attention. Styling was not too dated, always comfortable. Always knew the electric bells and whistles would be the end of the car. Front Air Dam was shot too. Engine temp slowly increased as the the Dam deterioated. Used extended warranty, paid for itself.
From the get go the car was awesome. Then the lack of starting periodically. Some said the ignition/alarm but I searched the internet and found the problem to everyone's trouble was the 1) BCM (body control module) Chevy charge $350 reprogrammed a new one and solved that problem 2) Rotors. Solved that too. Ceramic brake pads. Keeps the rotors cooler on contact. 3) Rack and Pinion. Shot but works like a BMW. Can totally feel the road now. 4) Corners bad-solved with polyurethane bushings to the sway bar. Now the perfect family sedan. Corners like a police car/mileage like a small car. Buy a 2003 on for Onstar 90,000 mile 34 mpg consistently on the hwy. Still a great multi-duty vehicle
