Well, to be honest the subject say''s it all. Ever since I have owned the vehicle I''ve had the bad light deal where all the light (ineterior/exterior) flicker. Damn that is annoying and unsafe if you think about on coming traffic that thinks your flashing them or something. If anyone know''s the fix please let me know cause the dealership sure doesn''t wanna help.
The start ups are a little rough. It kinda reminds me of when a car diesel''s when you turn it off, but in this case when you start it and it doesn''t start. Again, if anyone know''s the fix please feel free to let me know.
Thank''s alot for what may be the fix to my headache!

1) On the flickering issue, I have the same thing on my wife''s 2005 uplander LT. I am going to try replacing the battery before winter anyway, but I don''t think it is the battery. Best thing you can do is submit a complaint to the NHTSA about the headlights flickering which is what I did....if they get enough complaints GM will have to do something about it. Flickering headlights are a major safety issue....it almosts seems like the vehicle is loosing all electrical powre for a split second...like maybe a bad ground or something.
2) On the hard start issue, I have the same thing as well. It only seems to happen after the vehicle is warm + has only been turned off for a short time. For example, if I drive the vehicle for half an hour and then go into the store for 15 minutes, then come back out it doesn''t want to fire up. My brother-in-law has been a chevy mechanic since 1974 at the same dealership. He says that these cars are notorious for burning up fuel pumps...but that usually causes a no start condition....but we were talking and thinking it may be possible that the fuel pump has a bad motor and just isn''t building enough pressure...the car also seems to have no power at all...but then if you step down on the gas hard....about 10 seconds later it will give a surge of power. It''s not bogging down or hesitating at all though and I have cleaned the throttle body recently which hasn''t fixed either issue.
Some other issues with the uplanders in general are
-warped rotors/pulsating brakes, this fix being new rotors
-Fuel guage goes crazy....drop the tank and put in a new sending unit....haven''t done this yet on mine...but will eventually and I will also plan to do a fuel pump while I have the tank down just in case.
-The strap for the lift gate is so poorly designed that it brakes very eaily.
-Strut mounts and struts are garbage....don''t count on them lasting longer than 60k miles.
When I slap in a new battery, I will let you know if that fixes it...but this car would be gone if it weren''t for the fact that my wife loves it so much. I wlil not own another GM product that is for sure.
