I have a 2007 Impala with the 3.9 candy apple red. I have had it back 3 times for the hesitation in the acceleration. Twice they put a new map sensor in it, that did not help. The last time I had it in they gave me a bulletin from Chevy that they are a wear of the problem, at this time there is no fix to it. I do not like it, but per Chevy I have to live with it. I am not happy.
I have also had it back as I was having some dash problems. They had to put another ground in it some place, that fixed that problem.
Back to the problem with the hesitation, now you got me fired up again, its time to fire off another e-mail to Chevy

hello, looks like the impala goes back in the beginning of the week. wife has driven the car the last few mornings, and the same flickering in the electric system is being noted. no car i have ever owned has done this...wait, i have never owned a new car...... hmmmmm... it's funny an electrical gremlin like this made it into the second year of the new model. so much for my late father's advice to buy the second year of a new model. i will keep you all abreast. peace...... john on the fresh water west coast!

Is the flickering/pulsating constant or only when one of the elctrical accessories is used? For example, the headlights on my '06 Impala will dim slightly when I use the power windows. But once I release the power window switch the headlights go back to normal.
If this is what you are experiencing, I would say it is normal (I have owned several cars that also exhibited this type of behavior). However, if your lighting is pulsating/dimming/flickering constantly while driving then that is a problem that the dealer should easily be able to resolve...especially if it is doing it when the radio, A/C system, rear defroster, turn signals, overhead lights, etc. are ALL OFF. That leans toward one of the underhood components putting an abnormal load on the electrical system...or shorting out.
Do the lights flicker if you turn the headlights on manually using the headlight switch as opposed to the auto setting? If they do not flicker on the manual setting, it could be something as simple as a faulty auto-headlight switch or sensor.

hey ryster... i know when stuff like power windows are used there can be a dimming of the lights, but this is actually like a pulsing of the lighting system where the dimming is like going between say a 50 watt light to a 55 watt light and back again. it occurs randomly, and i compliment my wife on trying all different things as she's driving to isolate the source or cause of this. she did try the headlights manually to no avail. the car will be back to the dealer. i can't take the chance that the electrical system might end up funny because of this problem and have it bite me in the butt at 36,004 miles. i paid a bit more than i think i should have for a "certified" vehicle, but that was for peace of mind that the car is right. and right now.... it isn't totally right. any other suggestions are welcome. i get to drive the car after dark tonight, so i have a chance to check out a few things myself.

I have an '06 SS, no electrical problems whatsoever. You must have a lemon.

hey wbowl99, you were dead on, and when i did another online search for that TSB, i came across another forum http://www.automotiveforums.com/vbulletin/t880299.html that perfectly described the same problem as me, and the fix. armed with that, walked into my dealer today, they were impressed i found the problem, LOL i talked with the tech who replaced my alternator last week and he said that he never took it for another test drive at night with the car to verify he had fixed the problem. i told the tech i had told the service manager to keep the car for as long as it took to find the problem, glad he didn't. at first, he looked up TSB's on his computer for the 2007 impala, and it didn't show up. when we looked up the TSB number, there it was. the tech stated that he didn't find that TSB because it didn't show up under the impala category. odd. needless to say, he printed out the TSB and went right to the service manager with the information, the SM stated he'd get the parts located and delivered ASAP and that i can expect them to work on the car tomorrow. i will keep you all abreast. priggly, it appears as though this problem is confined to the 2007 impala and maybe the monte with the 3.9 V6, so hopefully i don't have a lemon. talk with you all soon. peace..... john
#153 of 272 programming a new remote
Sep 30, 2008 (1:38 pm)
hello.. picked up a new keyless entry for the 07 impala, and in following the instructions for programming it to my car, i haven't beeen able to get out of the blocks yet. in looking at a few different sites, the basic conceptual procedure is the same. close doors, hold down unlock button on car door, turn key to on,off,on,off, release unlock button; then car will lock and unlock to show it is prograrm mode, then procede with the remotes. i have tried several times to do that part of the procedure to get the car to do the lock/unlock thing, but i am not sure if my timing on the ignition switch part is right. is it a quick onoffonoff or a on, off, on, off, or is it on...off....on....off? any tips are as always appreciated. peace.... john

Glad to help John, and glad you got a different reaction from your dealership than I did when I mentioned TSBs. I was asked if I'd read the small print at the bottom and knew that TSBs were only for trained mechanics and not for me.
