Damn, I just typed a whole long reply and I accidentally erased it! [:'(] I will try again here...I called the customer service number again and told them my story...again. I complained about this being a safety concern, a nuisance, and a general annoyance when driving the vehicle. I also told him, mostly for the engineers to hear, that this problem does NOT seem tohappen in vehicles that have the V-8 engines that drop half the cylinders. I have heard from a few SS Impala owners, and we have a fleet of brand new suburbans here at work which I have driven and none of them exhibit the symptoms of the 3.9. Does anyone know if the similar cars to the Impala...Buicks and etc. have the same engine and problem? Are those owners complaining of this problem. Just out of curiousity...what cars are similar to the Impala? Buick Lucerne? Anyway, the customer service guy called my dealership to see if they knew anything he didn't, and then called me back. He said it is a known problem and General Motors is working on it (sounds like a broken record). I told him I know its a known problem because the last time I had it at the dealership they found the TSB about it, and disconnected the battery voltage regulator or whatever it is called, this did nothing to fix the problem FYI. Supposedly, when it was there, they had an engineer from GM to look at the car, but I don't know if this person ever showed up or not. If its a problem on the 3.9, and works on the v-8's, why can't they fix it? Argh.

 

G.M. must have done something on the recent LTZ's.
My late Dec.06 blt. and rbarriosFeb blt. appear OK.
And I realy check for this every time I drive at night and the lights
are not flickering.

yeah like n7jqp said, our 07 built in Feb has not displayed these symptoms.

 

does somebody know someone who works at a dealership or who has acess to TSB's? The latest TSB's should be checked, or even better yet, Technical Assistance Center (TAC) should be contacted

 

well, I just got off the phone with the GM custormer service guy. He said that my file is being closed because the problem was not fixed/they could not fix it for me, and that they are going to send me a Better Business Bureou letter in the mail...whatever that means. He did say the problem is still known and they are working on it, but he closed my account because he could not help me the day I called - for the second time! I told him the situation with the later build dates not seeming to have the probem, and he said he could not add that to my complaint, I could call back again, re-open my original complaint, and then add it in. What a bunch of BS, and these are the people who are trying to help us!

Here is another symptom of the lightsI have noticedwith mycar, does it happen with all of your cars that havethe lightproblem? When the car is running and in Park...like when you start it in the morning, when I shift from Park intoReverse and then into Neutral and thenDrive, the lights dim when I move the selector into Reverse on my way to Drive. They go back to normal after a second, but it definately does dim when I shift from Park into Reverse on my way to Drive. Park against a flat surface at night and try it and see if it does the same thing. I am curious to see ifyour carsdo this like mine.

 

When I talked to the GM support center to an East Indian woman I could hardly understand, I told her that I had the problem and was told by the dealership that there was no fix at this time, she said if there was no fix what did I want. In no uncertain terms I told her I want them to get off their *** and find a fix. I think that I have waited long enough. I don't think that going to the better business bureau will do anything or else they wouldn't be sending you a paper. I am thinking about going to the media. ABC has done things of this sort in the past, maybe if they start getting bad press about the way they are treating their customers,they might start thinking different. Every time I see an ad on TV about the Impala being a reliable vehicle, I get ticked. I have had three out of four of my last vehicles being GM products, but I think this is the last one and I will tell anyone who will listen about the way GM treats their customers. Maybe that's why they were almost bankrupt. Maybe if everyone who has been treated this way called some sort of media and got them to do an article, things might change.

 

Check and see if your state has a "Lemon Law". My state has one and basically if you have had it in 4 times for the same problem and they will not or can not fix it then you can ask for a full refund on your car less mileage. Keep good records. Google"Lemon Law"and the name of your state.

 

I have already contacted my state facilities inspector, and I will begin to pursue further action, because now my lights flicker no matter what, and no matter how fast i drive. I used to be able to go 75 mph and the blinking would stop. Now, it flickers no matter what. I am sick of this. But I am curious as to the later built ones which dont seem to have this problem...can someone who doesnt have this problem pop their hood and see if their alternator pulley has a black plastic cover on it? Maybe they got rid of the decoupling device that could be causing this headache

 

Black cap appears to be nothing more than a pully. I pulled and twisted it and it is solid.

thanks for the info, mine is the same, but if u look on the v8's and the 3.5l in the base models, their pullies don't look like that.
