Buick Lucerne Electrical/Lighting

    Inside the trunk there will be a felt cover. When you remove that for access to the taillight area, there will be some kind of flat tap that holds the red lense in. Probably three of them. I don't have a Lucerne but my 03 has corner lights that are held in by little taps on 1/8 inch diameter studs that are part of the taillight unit.

  • I have the exact same problem with my 2008 Lucerne. Seems like a software problem. If the program is smart enough to realize that when the sun is behind the car it is safer to have the headlights at the higher setting it should also know enough to turn up the cluster display. Possibly the system is designed so those two functions are linked. Controlling the headlight setting independently of the cluster illumination level combined with a software change should fix it if Buick so desires. This really isn't that tough of a problem for Buick to solve in my opinion
  • I have a similar problem as a previous writer. If my 06 Lucerne CXS is not driven for 4-5 days the battery goes dead. The battery will be completely drained, for example, the digital clock goes blank and the car cannot be taken out of gear. Really enjoy driving the car, but with this problem, it is not practical to leave the Lucerne at an airport or an underground garage or a jump start will be required. Also it is not practical to have a neighbor occasionally start the car if you are out of town for a period of time.

    The Lucerne has been back to the dealer several times since new and the dealer has been very cooperative, but the problem still persists. The battery has been replaced, alternator & charging system checked out plus software changes have been made without a resolution. The last software change was to reprogram the heater control module. The dealer is now saying that the battery drain is caused by OnStar dialing out every 20 seconds or so & the only way to prevent the drain is to mechanically disconnect OnStar. Still have several months of warranty left, does anyone have any suggestions on what is causing the problem?

    In Nov '07, I bought an '06 Lucerne CXL with the Northstar V8. It was still a new car. It runds great, when it starts...5 times in the 2.5 years I have this car, it has been totally dead after sitting anywhere from 1 to 3 days in my garage. This last time, on a Sat, my 6 yr old and I had to walk 3/4 of a mile to my parents house to obtain a spare vehicle. The dealership is baffled. GM is doing absolutely nothing. Today, I talked to Larry Salazar-I guess he is a District Specialist Supervisor-he offered nothing...I asked for the Owner Loyalty Certificates to assist in me trading out of my '06. He said "You simply are not eligible." What a croc. In the last month, the car has been dead twice and barely started one other time. I am on my third battery. I have had the On-Star modules replaced, the parts that control the heated/cooled seats, modules in the doors etc. I think GM should bu this car back. Until today, I wasn't too frustrated. I am now. Mr. Salazar offered nothing. This car is proving to be more and more unreliable. If anyone knows a different avenue I can take, someone else to call etc, I would really appreciate the information. My 6 yr old has said "At least when we have a loaner, we know it will start". Geez. I have phone #s of the theGM folks I have talked to if anyone wants 'em. All in all, this car has been dead 5 times and barely started the one time.

    Have you tried asking at a different dealership about someone who has found various problems causing a battery drain? Have you worked with just one dealer?

    I'm not trying to put it as your fault, but I'm hoping another dealer has a tech who has taken ownership of finding these odd problems. When it's dead, the module that didn't "go to sleep" to eliminate power drain has probably already changed its status. I'm thinking, however, they could take the car and monitor it for a few days with a computer device to see what doesn't go to sleep and drains your battery.

    the dealer had the car for 3.5 weeks after the 5th time...since my last posting, it has been dead 2 more times...GM is offering nothing, and my dealer is balking...the owner even made a "less than professional" comment this morning. I am ready to buy some of those lemon static stickers and drive around, once my car starts. they have monitored and monitored and monitored...had GM techs on the phone and at the dealership...all the dealer is offering me now is to trade me for a used Lucerne...I think this is outrageous...I bought a NEW Lucerne, I should get a NEW Lucerne. what a pain.

    GM wants to disconnect the heated washer fluid in Lucernes and others and pay us $100 for non use. I would rather have them fix it. Does anyone know of a website where I can complain or get action? I can't believe GM is too lazy to fix something like that, especially for expensive cars that a high percentage of the owners probably bought new. Their easy way out of this problem is astonishing. I would rather have the feature than the money. It was a unique feature touted on Lucerne commercials.
    I remember when OnStar went digital and older analog cars were going to be disconnected. Customer demand made GM change their minds and retrofit.
    I still love my Lucerne though and have had very little problems.

    I don't think it has anything to with laziness. Maybe you want to start a company to supply repair kits for the unit. There already was one recall in the past. The company that supplied the units is out of business if I recall what I read. When there are problems with units like this, I suspect the cost of supplying repaired units or repair parts is partly or mostly on the supplier and GM does the cost of supplying them to the dealerships and paying the cost of labor.

    Here's your opportunity to go into business. :)

    Personally, I can't see any difference between using a quality antifreeze mix that is above the cheapo methyl alcohol mixes and having the mixes heated. I see a risk of cracking the windshield with a heated mix indeed.

    So I say asta lavista to the heated units-hope that's the right spanish. I dont' see any reason you can't just keep on using yours. Don't take it in to the dealer and if you do make clear you don't want it touched, at any price, to disable the heater. I would say you're on your own risk there, however.

    I live in the South and don't recall having used it maybe more than once or twice. I'll take the money and go to the casino to have a little fun. leaving it hooked up or going to the casino, either way it's a gamble.
  • kcwolfpack59kcwolfpack59 Posts: 122
    How about if I take the $100, go to a nearby casino in Oklahoma, win big and with my winnings start up a company that sells good heated units to GM? Well, it's a thought. Seriously, I am going to get it disconnected. Thanks for the info.

    Had mine done yesterday. However the $100.00 check comes from GM. No telling how long that will take.

    I appreciate everyone taking the time to share their experiences with this problem. I bought my 2006 Lucerne (brand new) in 2007. I suspect, I am fortunate our battery completely died yesterday (first time) and at the house. Interesting that we just had a 50K service 2 weeks ago and the dealer reported no issues with the battery nor any electrical systems. Similar symptoms: No power. No dome lights, no dash lights, cannot open the trunk nor remove the key.

    My wife and I really like this car; but, have lost some confidence in Buick for not correcting this problem, nor recommending a trickle charger for a car with demanding energy requirements.

    Would appreciate feedback on the final resolution that solved your problem, if solved. I'll do the same. :(
  • We too have an 06 Lucerne and it just wouldn't start today. No sign of problems before this. Today I drove for 20 miles, shut off the car and it wouldn't start again. We tried to jump start the car but nothing. The battery was so low that the lights wouldn't even come on. The man that tried to jump the car said that the positive on the battery acted like it was not taking a charge. Any solutions? Had to tow the car in to the dealership becuase we could not get it out of park, the wheels were locked up, trunk would not open...

    Crowing blow was when the recker picked the car up he just dragged it onto the tow truck. Probably need two new tires now!
  • We are experiencing the same problem.

    My mother in law has a 2006 Lucerne and very frustrated as having the same problem with the battery going dead. She has taken the vehical to several different dealers with no luck.(WI, Florida and Missouri) They kept the car for 4 days on a monitor and could not find anything. Random dead battery can sit for several days or even after an hour.

    Thanks for your help

    I'm experiencing an unusual problem with my 2008 Lucerne. It doesn't get really frigid here in Virginia, but going home from work twice on nights when it was about 35 degrees, the third brake light would stay on after braking and the cruise control wouldn't work.

    Has anyone else experienced this?
  • nace818nace818 Posts: 140
    I'm just curious as to how a dead battery could prevent the key from being removed.

    My 2006 Buick Lacerne has been in the shop 9 times begining in 2007 and is scheduled to go back to the dealer Monday Feb 20th for another look. I drive at any speed either in town or on freeways and the car just decides to stop dead without any warnings. It stopped at a force that the motor mounts on the transmission were broken. The engine light nor any other light comes on that will give you any clue as to what has happened to the car. When one dies dead there is no controlling it, you have no steering or brakes. to add to problem the the Engine light comes on when you fill it with gas, or when you turn the heater on and for no reason when you are just driving down the road. If you wait a few days the light goes out. GM and the local dealer and the engineers are always asking for my car to duplicate the problem. They can't seem to do it. In the last 3 weeks it has stopped 3 times. Finally after 9 and now the 10th time sending it to the shop where no one seems to know what is happening with the car I decided to file the Lemon Law. This seemed to be the only way to get attention from GM or the Dealer. The car should have been taken off the street long ago. I am frightened to death in this car. My car has been in warranty and just turned 39,000 miles, it is not broken in yet. We had the battery checked at Auto Zone, but the dealer has not broke the seal on the battery so guess they only check with computer, no thinking outside the box. I think this is a very bad way to do the customers who pay these prices for a nice car. The car is a nice car. Would like to see it operate correctly and give me peace of mind where I don't have to wonder when it will stop and leave me in the middle of traffic and possibly cause others to get hurt. Hope no one else is having this problem?

    If the dealer and Gm are asking or your car to duplicate the problem it sounds like they are trying to find what is happening.

    Did you buy the car new? How many miles were on the odometer at that time?

    When the car dies the motor stops turning and the power steering pump and the power brakes are gone. There is vacuum left in the power brake assist unit so one application down on the pedal should be used to stop the car without letting up again. Letting up depletes more of the vacuum and the next press down gets less assist force.

    The car should not stop with a lot of force slowing it down: it should coast losing speed gradually if the engine dies. A force slowing it down rapidly enough to break a motor mount sounds like a transmission problem.

    The engine light turning on steady without flashing when filling up would be a pollution system related problem. If it goes out after a few days, is that when the tank level drops below 3/4? The pollution system for fuel vapors on my Buicks checks for leaks when the tank is between 1/4 and 3/4 full and a couple of other conditions are met, one of which is a lukewarm restart on the motor. If that's when it turns off, your problem is clearly with a sensor or relay in the fuel vapor parts which includes a carbon cannister.

    Has the dealer suggested just keeping the car for a few days and having a mechanic drive it as their own until symtpoms happen again? They should give you a loaner vehicle or one out of used car inventory to drive and use yours. Once the mechanic felt the stop that you have tried to describe as being a quick slowdown, they would know where to start looking.

    08 Lucerne 39k. Occasionally the car will not start. Attempting to start it makes a noise like a chirping sound. Then nothing. Multiple attempts and 10 to 20 minutes later the car will start and run great. Happens 2-3 months apart. Dealer can't fix it because it is intermittent and they can't get it to do it. Has anyone else had this type of problem?

    Purchased a oxygen machine which has a DC adaptor and connects to the accessory outlet which is fused at 20A. The adaptor keeps blowing it’s fuse (10A) and the black box is extremely hot. Vendor says the car has a limiter in both the cigar outlets which causes the problem. Buick dealer provided a schematic of both circuits which shows no limiters and tells me the problem is the adaptor is insufficient to handle the electric requirements of the machine. Don’t know where to turn next. Any help would be appreciated.

    I would try the black box adapter in another vehicle's accessory power plug. If the fuse blows again, it's obviously the black box adapter's problem.

    I have a 08 cxl since new and it has been burning oil since new. My dealer has indicated that an acceptable oil use is 1 litre every 5000 kms. I find that burning of oil very unusual and question the dealers integrity.
    Does anyone have the same problem?
