Unfortunately no replies to my message. But in the spirit of helping others, just wanted to mention the outcome of my issue. I took my car to the dealer. The service representative was nice enough to do a quick drive the car and suspect the transmission - so he persuaded me that we should do a transmission diagnosis. Unfortunately, they didn't get to it that day and I took my car back that day (Wed). The next day, as I drove the car, I was more or less convinced that it was a transmission problem since the car would tend to stall more when going up hill. When I changed to a lower gear, it took off. Anyway, dropped off the car to dealer on Fri. The dealer diagnosed it as a constricted catalytic converter. Fortunately, the catalytic converter is covered beyond the 3yr warranty and was replaced by the driver. Now that the acceleration is back - you guys watch out for this maniac in the Impala!

I had the check engine light come on about a month ago. I was near the end of a tank of gas. After about a week, and a fill up it did not go out on its own. I finally got a chance to check the code and it was due to this P0440 code also. I reset the code. Fortunately in my case, it has not returned. There were no noticeable problems with the car. I can't say I noticed the how the pressure felt when removing the gas cap. I'll have to pay attention to that at the next fill up.

#1451 of 2014 2003 LS three problems
Sep 02, 2005 (12:43 pm)
Great forum! Thanks! I have a 2003 LS(78,562 miles) which eats brakes, shudders on load, and worst of all has a clunking sound up front. The first brakes and rotors were replaced at 11,000 miles (was a serious grinding sound). The whole car has a shudder that can be felt most at higher speeds and under load (climbing an incline), not so bad down a hill. Mainly under accelleration. The worst problem is the clunking sound. When I bought the car i had none of these problems so I know something is wrong; but what! I just wish that whatever it is it would just break. That way a mechanic is sure to find it. As it is right now, the mechanics say 'needs brakes" or "bad rotors" or "rotors need to be turned" or "tires need balanced" or "need new tires" or "tires need to be rotated" or sometimes all of the above. I read in some of the ealier posts about the bad cradle but that seemed restricted to the 2000 model. I also read something about the intermediate shaft that might handle the clunk but would that take care of the shudder? Any help would be appreciated. I just want to give the locl mechanic some ideas to fix my car.
#1452 of 2014 Whine under a certain speed range
Sep 03, 2005 (9:48 pm)
2001 Impala base 46K miles.
Recently developed a kind of whining noise from the front. The whine can
only be heard when the car runs in roughly 20 - 30 mph speed range (sometimes 20-25mph)
Tried switching gear to neutral when whining, most of times the noise is
still there until the car slows down below ~20mph.

i own a 2003 impala.heres my list.rear rotors resurfaced 12000 miles.steering shaft and outer tie rod ends at 28000 miles.rust in left rear inner door threshold.body control module at 38000 miles.ignition switch and pass lock module at 39000 miles.and now at 48000 miles intake manifold leak.gm rep basically told me that since maintance was not performed at a dealer and that only warranty repairs were done at the dealer that he could not help me.car was serviced at a pro care since new.anyone else have all these problems.

I have an '03 Impala and never had any problems until I was in an accident recently. The front of my car was hit mostly on the right side where the headlight is but the damage extended across the other side of the hood as well. One of the parts damaged was the engine cradle and the collision center that was doing the repairs had to send it off to another shop to fix it. So five weeks after my accident, I was told that my car was finally finished. Only a few days after getting it back, I noticed a slight creaking noise when I turned the wheel. By the time I took it back to the collision center to be checked, it had gotten worse, occurring more often. So the collision center sent it back to the other shop to be fixed and I just picked it back up last night. As soon as I turned the wheel to back out, there it was again. The shop was already closing so I drove it home to make sure that the cradle was for sure what I was hearing. On the way home it was getting worse. Not only did it creak when I turned the wheel, but also when I would accelerate or brake. It was constant with every movement of my car! I called the collision center just a few minutes ago and they apologized..blah blah blah..and just asked me to bring it back in when I could and they would send it back to other shop.
The guy at the center responsible for my car, when I asked him why there could still be a problem, said that it's probably just some bolts that aren't fastened properly. Now I don't know a whole lot about cars(I am going to start learning more after all of this, however), but I'm not seeing how just a few lose bolts could be overlooked twice already, or could there be a bigger issue here? Could somebody explain the structure of a cradle and things that could go wrong with it?
#1456 of 2014 '03 Impala LS - ISS Replaced @ 55,000
Sep 10, 2005 (3:33 pm)
I've had Impalas since 2000 and am very familiar with the ISS issue. I had hoped that by '03 the issue would have been resolved, however not. Back then, the fix was to replace the ISS. That was too expensive for GM, so for a period of time, the solution was to lubricate the ISS. Now in the summer of '05, the updated TSB calls for the replacement of the ISS again. I hope that means they finally got it right this time.
Anyway, last week at 55k miles, I needed mine replaced due to all the usual suspected conditions, etc. It could me $200 and they would not cover it as a warranted item. It time to contact GM and asked them why I have to pay for an issue that's 5-years old, regardless of how many miles are my Impala.
That being said, it feels like a new car again. The suspension feels tightened up, smooth and very responsive.
