Buick Lucerne headlights problems

Filed Mar 16, 2019 · Electrical, Lights · 63,000 miles · IL

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 manner at no certain interval; now the "service battery charging system" dic message along with the red battery dash light comes on and goes off also at no specific time or interval ( at which time my heater/seat warmers/radio/etc shut off ). I am able to force the dic message and battery dash light to go away upon my revving the engine or accelerating drastically. I have had both the battery and the alternator checked and both are in good working order so now, after some online research, I will check the fuses and relay switches more intensely. I pray I am able to find a solution as I really do love my car. Also, last week my transponder key quit working in the ignition and had to use the fob remote start to start the engine, thankfully upon checking the fuses under the back seat ( I guess from removing and replacing them ), the key and console ignition did start operating normally again. And I checked my VIN # on this site and it is returning clear to having no current recalls. I am however worried of some of the stories I have read regarding malfunction, I fear I may be facing a future alike incident so if anyone has any solutions I am all ears. Thank you...

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.

Head light failure due to passenger side relay harness module failure. Low beam lights failed on dark night on mountain road. This problem has been reported by numerous buick lucerne drivers. Buick obviously knows there is a problem because they offer a replacement front light harness module that must be spliced into the existing main light harness to replace the original equipment module. This is an obvious manufacturing design defect and a difficult module to replace. The replacement module is approximately $50 and the replacement labor is around 1.5 hours. With normal use this light module connections shorts out because of the overload on the module. Why hasn't this problem been considered for a recall? Gm has admitted it is a design defect with the availability of the replacement light harness module wiring kit. My wife almost went off the road and wrecked when the lights went out.

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. This is a safety issue because this connector can fail at any time and it is impossible for a non-mechanic to repair this connector in the field because access to the connector involves a partial dismantling of the bumper shield and special tools. The fact that there is a kit to replace this connector suggests it is a design defect in either the wiring or the connector and that it should be considered a recall item because of the potential danger of sudden loss of headlights. My lights went out at night while driving in mountain terrain. I have gone on the internet and this apparently is a problem that has been experienced by a number of buick lucerne owners. This is an engineering mistake and gm should be forced to recall these cars and repair this design defect.

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.

This electrical problem began about the first of the year when the electric door locks started to cycle while driving. It has since migrated to turning off the cruise control and causing the headlights to flash off and on. The remote start will start the car but will shut down the motor after a few seconds. These problems continue during every operation. I have been informed by the dealer that it is a p140 code and will take about 3 to 4 hours to diagnose where the problem at $80.00 per hr. Plus repair.

Tl*the contact owns a 2006 buick lucerne. The contact stated that he has moisture vapors covering the high and low beam headlights on the passenger side of the vehicle. As a result, his headlights are not shining bright enough. He took the vehicle to the dealer and they stated that the headlights should clear up within two to six hours and work properly again. No repair was needed because the failure was caused by atmospheric conditions. The failure mileage was 1,400.

The digital odometer and radio gauge readouts are pitch dark and are impossible to read when the auto-headlamps are turned on during daylight, such as right after exiting a garage, a tunnel, parking structure, etc. Warning messages are also displayed through the same readout area.
