  All things that gone wrong - 2003 Chevrolet Impala
  By deaun - August 5 - 1:53 pm

  My family has always been a Chevy patron. I liked the looks, drive and amenities of my Impala, but in the last 2 years I have had to replace the catalytic converter$739, the solenoid $875(when I took it to the transmission dealer they had been told by the GM company to start carrying this part as it was defective) the intake manifold ($783)wheel bearing, I will never purchase another GM car.

  Car is Junk - 2003 Chevrolet Impala
  By Shawn - July 6 - 2:44 pm

  Bought car second hand, still under warranty.It refuses to start (wont 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.

  GM has knowledge of existing problems - 2003 Chevrolet Impala
  By Super pissed - May 3 - 12:03 pm

  MANY PROBLEMS! This is not my first GM car and I always keep up with the maintenance on my car. Bought my 03 Impala 01/07 with 40,000 miles. Had the catilytic converter replace and back lighting in dash. Last year had $4000 worth of transmission work done because of slipping. Had the intake manifold and gaskets replaced due to the dexcool that gm uses in Dec. here I am 5 months later with a blown motor at 96,000 miles. There are many lawsuits against Gm for the damage the dexcool coolant causes. ADD ME TO THE LIST! Sad to say i will NEVER buy an American made car as long as I live.

  Very Disapointed - 2003 Chevrolet Impala
  By Courtb86 - January 8 - 9:37 am

  I bought this used - 1 owner before me. Drove great at first - loved the car - then this year everything just crapped the bed at once. The transmission went. I love Chevy but I will never own another impala again, my cavalier was more reliable than this car.

  Very Angry at Chevy - 2003 Chevrolet Impala
  By boinjax - May 17 - 10:47 pm

  As a long time domestic car fan, especially GM, this has sealed the deal for me... NEVER AGAIN, in addition to 3 thermostats, a water pump, radiator and 5 sets of brakes, not to mention a common electrical problem linked to the pass key, now the transmission went out.. the car only has 105k, other INTERNET sources found identical problems from 100-130k miles, the car was bought new, female driven and meticulously maintained, but this car isnt reliable, just decides to run hot and arbitrarily wont start, dealers want a fortune to fix even though they are aware of these problems as common, no wonder the police wont drive them, used to love GM, now, HATE THEM wont even rent a GM car...too bad

  Consider Something Else - 2003 Chevrolet Impala
  By Bill - February 5 - 6:05 pm

  The car hasnt been terribly unreliable, but the front brakes and rotors wear very quickly. Also, the transmission started slipping after only 50,000 miles and had to end up being replaced. I wish this would have happened under warranty. I just wish some domestic car maker could put something on the market that would last at least 100,000 miles.

  Wont Buy Another Chevy - 2003 Chevrolet Impala
  By PhilNTexas - August 10 - 12:15 pm

  Bought the 2003 new, previously owned a new 2000. The 2000 my below average, but the 2003 is a really crummy car. 21mpg, too low, Horrendous road noise that the dealer couldnt fix. cant keep tires on it, 2 sets in 55k. No torque in drive without hitting passing gear. I had the extended warr, but have had constant problems, motor mounts caused the engine to strike the firewall, rotors were out of balance, replaced myself, check engine light problem, the dealer kept it 2 days, and finally said a squirrel had chewed a wire. If you believe that I have a bridge I want to sell you. Last problem was traction light came on, and dealer wanted $1200 to fix, but finally after many meeting, fixed it.

  Disappointed - 2003 Chevrolet Impala
  By Gman - August 4 - 9:57 pm

  Bought the car new. I dont put many miles on it, so Im especially disappointed. Thought it rode nice at first, but not so much now. The car has ample power. No problems with the drivetrain. Brakes are terrible, and the steering shaft clunking (apparently a common problem) has me really hating this car. Rotors are so warped. Rear rotors are so grooved and rusty, they must barely be working.

  OK Car - 2003 Chevrolet Impala
  By ayadre26 - January 22 - 10:22 am

  I traded in the my 2002 Chevy Tracker in for this car for more room, better performance and less problems for my family. At first I was happy, now Im having all kinds of problems with this car. From replacing all 4 brakes, rear rotors, computer malfunction,bad battery when the indicator said it was good, 2 fuel injector failure, replacing a converter, and now every once in a while the security message come the message display. Tech said to watch, might not be anything. Other than these things the car has been OK. Would have like an armrest for my right arm. I do love the design of the car. Might not buy this car again.
