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.
This is an awesome, big, comfortable car. Its handling is great and it is very smooth driving. The gas mileage is great and it has a great safety rating. Finally a 4-door sedan that is fun and practical to drive. Congrats Chevrolet on a great car!!!!
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 $1,200. Despite those issues I've had no other issues I love my car. It rides real smooth and has some nice power. Has great gas mileage on the highway. This is really the last stylish model before the new Impalas went out. The interior is very nice and there is plenty of room for 5 people to fit comfortably inside. Currently at 104,500 miles and the car is still running great!
Where should I start........ it was 2010 when i got my impala only had 70k it was the best car for about 4 months first at 85k the catalytic converter (600$) then the power windows went out (130$) then the oil gasket/pan (30$) did it myself then dash lights went out didn't fix it then ABS was going in and out then water pump (50$) did it myself then the thermostat (10$) and I've only had it 10 months now I'm just like what's next?? MY parents own 9 different chevy's 1971-2010 and this is the only one that as ever disappointed them.
8/1/2017 UPDATE: STILL RUNNING STRONG! Edmunds has asked for another update today, 1/28/2017, a year after a voluntary update, five years since my 2012 review, and eleven years since my original review. Well, the car is still running perfectly! It stills has its original exhaust system, and continues to run well with regular oil changes and tire rotations. We did just have to have the original oil switch replaced ($137) last week, and today I purchased a new set of wipers. Otherwise, the dang car just keeps going! 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. 1/25/2016 UPDATE: I just had to update my review to say it's STILL GOING STRONG! We have done nothing but routine maintenance since 2012, and we still love it!
