I've got a 2007 Grand Prix with sun roof--essentially the same mechanism--and I have not experienced whaqt you have described. I live in Texas and the car sits in the sun during the day so it gets to 100 degrees or greater. Sounds to me that you have something that needs adjustment or lubrication. Good luck. Clark

new owner, 07 3LT, 3.9, black, ebony, 26k by john_gilius

hello all. just purchased a certified 07 impala with 24,771 on it about a month ago. it is a beautiful car so far, no big complaints yet. has all options except bose (thank god, my 84 vette's bose sucked!) and it replaced a still thriving 160k 92 mercury sable LS. just wanted to post that the car has already been back to the dealer for a brand new alternator. it exhibited a pulsing in the interior lighting/blower/headlights when driven in the dark. changed variables inside the car over a week (fan on and off, a/c, fog lights, radio. rear defog, etc) to be sure it wasn't just one item drawing the electric system down. my guess of alternator or voltage regulator was confirmed yesterday, installed today, and the car is safely back home. let's hope that's the last major issue for the next 140k, LOL peace..... john in grand haven, mi

The Bose in the new Impala is hardly the same one as in your '84 Corvette. You can't compare the two. The Impala Bose is actually excellent. I have it in my '06 SS and it is one of the best features of the car!

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.

dangitall! by john_gilius

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.

There is a TSB that deals with the flickering headlights and interior lights for the 06 and 07. I'm not sure what the solution is but you can see it at http://www.chevroletforum.com/recalls-and-tsbs/make_CHEVROLET/model_IMPALA/year_- 2007/id_070842008/TSB.htm
