2007 Buick Lucerne Lighting problems

I purchased my '07 buick lucerne cxl about a year ago ago an I actually love the car however; about 3 or so months ago I noticed a what I am suspecting is the transmission or possibly a censor or relay issue causing the car to make a hesitation and drag when I try to keep a consistent speed and only quits when I press or depress the gas pedal making the car either accelerate or decrease in speed drastically. Also, about a month ago I noticed the headlights and dash lights get brighter and then dimmer in a flashing...

Both right and left headlights, both hi-beams and low beams will not illuminate. All other exterior lights work. Ac delco 22860591 body control module has been replaced and programed. All fuses and relays have been checked. Headlight switch # 15926061 (without fog and trunk release) replaced. Head lambs still do not work. Without headlights this car is unsafe to drive.

The passenger side head lights failed and the problem was not the bulbs. The primary connector for both the high beam, low beam, and turn signal lights proved to be defective with a burn mark on the terminal that supports the above lights. I was advised by the buick dealer that there is a kit to replace this connector because it is a known problem.

2007 Buick lucerne. Consumer writes in regards to rear view cameras and automatic headlights in all cars.. *Smd

Left home in the evening and turned headlights on. Noted the highbeams were on and tried to change to lowbeams, but headlights remained on highbeams. *Tr

Instrument panel on 2007 buick lucerne difficult to read in the daylight. The gauges are recessed in tunnels such that the light doesn't make reading the temperature ,gas and speedometer readable. This is a design defect. *Tr

Re: 2007 buick lucerne. In daylight driving the instrument cluster is not visible. Very hard to read odometer or gas gauge, have contacted dealers with no success in solving problem. *Tr

Dash cluster display is unreadable during daylight hours depriving the driver of critical information which could present a safety hazard, viz., Speed, engine temperature, oil pressure, etc. I notified dealer of this problem a few times and they replaced the cluster; however, the replacement was no improvement. The dash is still illegible during daylight hours. I have followed up with the dealer on this defect and was told that there was no fix for the problem. *Tr

The xm radio gps panel can not be dimmed at night this is a serious safety problem and can't believe it cant be fixed. *Tr

2007 Buick lucerne lighting system on the dashboard becomes invisible at different times. *Nj the consumer stated the dashboard cluster was modified, but it did not help. *Jb

Cannot read the odometer or fuel gauge when driving in sunlight. It is completely dark when it is sunny outside. Dealer suggests tinting windows?? Panel has been replaced, but still same problem. Is buick going to do any thing about this??
