  • It's still under warranty and will be visiting the dealer ASAP. The dealer said no TSBs on it, so I was hoping that someone on this board might have a similar experience so I can relay info. to the dealer. They will probably run their hydrocarbon emissions tester over everything to find it. In the mean time, its parked outside. Thanks.

    The owner's manual for my 2009 Lucerne states that the oil life system will indicate when the oil should be changed, yet a service adviser at a GM dealership says that it should be changed every 3,000 to 5,000 miles and that the oil life system can be inaccurate. Do you follow the oil life system or the advice given to me? In other words, who should I believe--the manufacturer or the service adviser of one of its own dealerships?

    After a very long drive in my 2009 Buick Lucerne, which has 10,000 miles, it had a very loud humming noise from the trunk, the source of which was later identified as the fuel pump. Two mechanics listened to the humming, which by then was much quieter since it is much reduced in city driving, but both have no previous experience with this condition. One said that the fuel pump is a very powerful machine and that it's possible that when the tank is low on gas it makes more noise since it is no longer submerged in gas which would insulate the sound. My feeling is that it's not normal for it to be humming at all to begin with, much less when it's practically screeching, but the two guys have nothing to compare with, and so I'm left with this noise coming from the trunk. Does anyone know anything about this noise or have had experience like this?

    Follow the advice of the manufacturer/oil life system. The service adviser's advice is designed to drum up business for the dealership. Oh, and use synthetic oil, not mineral oil. The synthetic oil is better in every way except a marginal increase in price which is well worth it.

    Your car is under warranty. Have the service manager listen to the pump noise with a low tank if that's what it takes. If he doesn't agree there's something needing work, then ask for the dealership manager to ride with you. Do it before 12,000 miles.

    I wonder if something is touching somewhere outside the tank and transmitting a normal vibration so it's amplified inside the usually quiet car.

    Or the pump is going bad

    Or the pump needs to be removed and checked--through the opening in the trunk that makes it a relatively easy job.

    Warranty. And do it before 12,000 when they expect to take care of little things like alignment and balancing. Then after that they begin to feel those are owner problems from normal wear and tear.

    I Bought a 2009 Buick Lucerne that had 7000 mi. on it
    after a few days I noticed a low rumble from the rear at
    about 58 to 65 mph and now at lower speeds. I took it back
    to the dealer and they put a complete new exhaust system on it.
    It seemed to help until I got it home. It's still there.They can't figure it out.
    It's more like a viberating rumble. thanks for any help Jim
  • We have a 2008 Lucerne that has had the battery run-down problem. This happened after the car sat for 3 or 4 days. Had it back to the dealer 3 times. They could find nothing, but did install a new battery. Interesting that it was mentioned in another reply that the ONSTAR was the problem. I too am having onstar problems, which the dealer is yet to resolve. Guess I'd better print this off and take it to the dealer.
  • I have 2006 buick Lucerne CX with a fast left turn signal light and a left rear tail light that needs to be replace. How do I replace the tail light and is there a fuse or something that may be causing the fast left turn signal. thanks for your help.

    This is exactly what it is made to do. If you burn out a bulb, it causes the blinkers on that side to operate faster. (sensor detects the change in resistance from a burned out bulb and operates the blinker at 2x the normal speed)

    There should be an access panel in the trunk. It uses standard automotive bulbs.
  • Jimmy you have been had just as I was. I bought an 07 Lucerne CXS (a demo) with 6000 miles on it. From the get go I noticed a vibrating/rumble at various speeds. I took it back to the dealer around 8 or 9 times. They rotated and balanced the wheels; didn't help. Took it back again and they did the same thing again; same result. Took it back again and they said the front rotors were out of round (aka=warped, so they turned them). Didn't fix problem. Took it back again and the dealer said one of the wheels was bent; they replaced it and still no fix. Took it back again and they road force balanced the tires and determined that I had two bad tires which they replaced. No good. Took it in and met with the GM factory rep who said it didn't vibrate that much. He said he had seen them much worsse and told me to turn up the radio - with a straight face. I told him I didn't listen to the radio as it was a disrtraction. Also, both of the front seat belts were defective as was the tire pressure monitor as was the fuel sender as was the window washer fluid ssensor.. When I got home, I parked the car in the drive and for some reason left it running and reved the engine a little at a time and when it got to 1500 rpms, the whole car vibrated. The problem is inside the engine, not in the suspension, etc. I took the car back again and the dealer had the engine and transmission lifted off of their mounts and had it "centered" back on the mounts. This did absolutely n othing for the problem. I brought it back again and this time the service people had a conference call with GM and the engine and transmission were lifted off their mounts and some of the mounts were replaced. Nothing. The car still vibrates whenever the engine is running at 1500 rpms. It is a manufacturing defect in the engine. I filed a lemon law suit. GM offered me $1600 to go away. WTF!! I had paid over $30,000 for the car just 9 months ago and they expect me to live with their crappo car. I told my lawyer that I wanted GM to buy back the car. I was told that they had never seen GM buy back a car with this typoe of problem. The lawyer went back to GM and they offered me $2600!! I don't know what is up with them but I told my lawyer that GM could stick their $2600. The minimum amount that I would even consider is $10,000. I could then use that with the miserable trade in value on this car to get into a Nissan or Honda. GM is a mess. This car which cost me over $30,000 last June is now only worth about $16,000 in trade. It has depreciated $14,000 in 9 months. And it only has 9000 miles on it and is loaded with every option available. It stickered at $42.000 when new. So much for good old GM products. I told the service manaager that all that I really wanted was for them to fix the car. He told me that he could not fix my car - period. And GM was not going to authorize any more attempts to correct the defect. Unbeleivable!!! Whatever happened to Mr. Goodwrench?? Where is he when I need my poor excusse for a car fixed?
  • plektoplekto Posts: 3,738
    I didn't notice a problem. It vibrates that way because it's a V8 and probably needs a less restrictive exhaust. I don't drive at 1500rpm, ever, though. That's lugging the engine and isn't good for it.

    I have a 2006 CXS & would like to upgrade the headlights to an HID Xenon setup or at least a bulb upgrade to Sylvania Silverstars. It looks as though you can not replace any front end bulbs without dropping the front bumper clip (absolutely insane). If this is true, is there a shortcut or trick to accessing the front lights and is there a GM mechanic or lighting specialist out there that can direct or suggest a superior product and an appropriate route to take. I want lighting that is long lasting, trouble free, with an installation that is the least complicated and intrusive to the vehicle. Also, I'm in warranty to 2012 and want something that will not conflict with the wiring harness and cause any damage voiding the warranty. I'm in the Phoenix Metro area, so if anyone can recommend an auto lighting specialty shop or product, it would be greatly appreciated. Thanks! CXSROBB

    To be honest, I hadn't been in the car market since 2008 and hadn't kept up things like engines, etc.

    I ended up buying a 2009 Lucerne CX for my mom, with the 3.9 V-6.

    Having the 3.5 DOHC in my 2000 Olds Intrigue, I thought this was also an DOHC because it was so smooth and had plenty of pep.

    If you want a race car, then you want the V-8.

    But the 3.9 V-6 in the car I bought is no slouch.

    Mileage during the first tank of gas was 16.5 mpg. But considering that this was the first tank and my mom never drives more than 8 miles at a time....
  • Well, here I sit boken hearted. I have just been asked to leave my dealer's service area by the owner of the dealership because I was "haranguing" his employees. What I was doing was asking for them to fix the vibration in my car - a 2007 Buick Lucerne CXS, no more and no less. Well, evidently I was way out of bounds with my request which was for them to get rid of the annoying vibration which occurs whenever the engine is doing 1500 rpms. Someone on this site said that this is lugging the engine. Well, just glance at your tach; you'll be surprised at just how often it is doing just that when driving. I also requested that they fix the tire pressure monitor which is dead in the water. Well, the owner the el presidente of the dealership in no uncertain terms told me to leave and that they would no longer work on my car. Gee, I wonder why they have a service department and why the car came wilth a warranty which the dealer is not honoring any more. He told me that he would set up an appointment for me at another dealership - my how kind of him. He should have ushered me out of the door when I got stuck with the car which he had driven for 6000 miles and that he knew darn well it was vibrating. His employees told me that he is a real nit picker so I know darn well that he had them trying to fix the vibration, but I guess that they couldn't then either. I accused him of covering up the defect in the car and he said he didn't care. I guess not; he already has my money. When I first arrived in the service area I was told by the service writer that he didn't think that they would work on my car because I had started a lemon law suit. I never knew that action allows the dealer to cease performing repair work on the car under the warranty. But, I guess all bets are off now with GM about to fall flat on their collective face. I never had this kind of problem with the dealer not being able to fix a problem and then just kicking the customer out of the dealership. But then, it is 2009 and all bets are off. At least I can enjoy watching GM crash and burn; they have brought this nightmare on themselves; it is just a shame that a lot of honest hard working people are being made to suffer as collateral damage from this debacle. Semper Fi
  • In my current quest to unburden myself of this poor excuse of a car - the Vibrating Hulk of a Buick Lucerrne CXS (I wonder just what "CXS" means, hmmm??), I did a lot of auto research and testing. And, surprise, surprise, that new kid on the block (well, kind of) Hyundai has quite a nice car which rated an 8.3 in the Edmunds review versus the lowly 6.8 earned by the Buick Lucerne. I should have done my research a year ago ....Well, I think that I am going to TRADE UP FROM BUICK TO HYUNDAI!!! The Hyundai Azera Limited with the Ultimate package is head and shoulders above this Buick dionosaur - an old platform, with an old engine linked to an older transmission with halogen, yes halogen, headlights. I am surprise they don't still use kerosene lamps by golly. I have owned over 40 cars in my 73 years and I have to say that the worst of the lot is by far this %^%^%$% (excuse my language please) Buick Losecerne!!! I hope to unburden myself within the next day or so before its value drops any lower; it has already dropped $14,999 since last June. UNBELIEVABLE!!! Many of the dealers told me that I should get rid of the car before GM declares bankruptcy which they are definitely going to do in June - the one year anniversary of my dumb deal for which I blame myself - I should have known better. Whatever happened to "with age comes wisdom..." Duh on me. SemperFi P.S. If you see an 07 White Buick Lucerne CXS for sale with only 9000 miles on it, just keep walking....

    Make sure you thoroughly research and test drive the Azera before you trade. Azeras have a well known issue with their suspension. No company currently makes aftermarket struts/shocks for the Azera, so you are at the mercy of Hyundai if you experience issues. You could end up trading one problem for another of equal annoyance.

    Also make sure you fully understand Hyundai's warranty. They like to tout their 5yr/60K mile standard warranty (and 10yr/10K mile powertrain), but NOT everything is covered during the 5y/60K miles. There are numerous components that are only covered 3/36, and even some that only have 1/12 coverage. If you are buying used, you will not receive the 10/100 powertrain. Second, and subsequent owners, are only entitled to a 5/60 powertrain warranty.

    Resale value on Hyundai is no better than Buick. I just looked at a 2008 Azera Limited with only 7500 miles on it this past weekend (I had considered trading my '06 Impala). Price was $19K. Rumor has it the 2009 Azera will be the last year for the Azera. The Azera also uses halogen headlights. They may be projector beam units, but they are not HID's...just standard halogen bulbs. I found the Azera's interior to feel rather confining. The overall assembly quality and materials were not impressive. The center console creaked if I just touched it, and it felt very flimsy (and this was on a unit with only 7500 miles.) Leather quality was poor. Overall, it was a very disappointing experience. The interior was so unimpressive I never got around to actually driving the car. The dealer actually has 5 of these low mileage '08 Azera Limiteds on the lot and they have all been there for at least a month.

    I have owned 10 cars in the past 20 years, 5 of which have been GM vehicles. I used to be a GM fan, but my experience with my current '06 Impala has driven me away from GM in the future. My Impala is 3 years old and has 41,000 miles on it. It was $21K when I bought it new, but now I would be lucky to get $7,000 on a trade. My Impala has been the most trouble-prone vehicle I have ever owned (water pump failure, power steering issues, brake issues, steering shaft issues, peeling trim, numerous interior squeaks and rattles, etc.)

    I continue to look for a new vehicle, but it will not be a GM or a Hyundai.

    You bought the car used IIRC>

    Have you checked to see who owned it initially and why they traded it?

    I would suspect the dealer hid the existing problem from you. It may have been bought back as a lemon previously.

    I'd find out what I had to do for a title check on the car, maybe an attorney that specializes.

    Another dealer might be able to check based on VIN to see if it was defective and traded back in. Their VIN check would show service attempts on the car.
  • cooterbfdcooterbfd Posts: 2,770
    I would definitely go to another dealer w/ this problem. Our '04 Rainier had a slight vibration in it while turning at parking lot speeds. 3 TIMES to the selling dealer, and they couldn't find it. Finally, I got fed up, and replicated the problem in my driveway. It was the PS hoses vibrating. I brought it back with the newfound info, and told them. They said it was normal for the hoses to flex ( I said shudder). That's when I knew I was dealing with idiots.

    I brought it to a competing dealer, told them about it, they put their best mechanic on it, and w/in 5 MINUTES they had found a TSB on the Steering rack. They had it taken care of in one trip !

    I am surprise they don't still use kerosene lamps by golly.

    LOL. Good one.

    I just popped in. This is the first I've heard of the Lucerne having problems. I read Consumer Reports religiously and they have it on their recommended list.
  • Got a "final" offer from GM to make me go away; it is $4000. A far cry from a buyback, eh what? My attorney's office is processing paperwork; however, I took the el presidente's advice and went to another dealership. The service manager sat in the car, started it up, and rev'd it up to 1500 rpms. Yep. Good old vibration right on cue. You could use the car for a sex toy (almost). He confimed that vibration is not normal; it is a definite problem in the engine; he will take it into his shop on Monday and attempt to correct the problem. I must pause here in this saga because up until now all of the GM people just couldn't seem to feel that this was a problem and the car was performing as designed LOL. Here was someone actually confirming that this is a problem. I kind of got the impression that the negotiations with GM were skewed by the Mr. Badwrenches who had worked on the car previously and was funneling bum info back to GM corporate HQ. I told the new service manager on my quest about all of the previous efforts to fix the problem and he kind of brushed them off saying that he would go ahead and contact GM on Monday and go from there. At this point I do not know where I stand with the $4K payoff. I am darn sure that I am not going to bend over for GM and let them shirk their responsibilities for repairing the car under their warranty. And I am considering backing off from the proposed $4k settlement in deference to having the engine problem corrected. This whole fiasco was the result of poor procedure on the part of the dealership's service people from the get go. This whole thing gets crazier and crazier. But then there is the upcoming backruptcy of GM and its effect on their abililty to continue to service their cars under the GM warranty. They do not have the necessary funds to provide this service and with the talk that they are going to dump around 1500 deealers, the GM service base is going to shrink as well. I know for a fact that the service writer was joining in the circle jerk in the service area and their ineffective attempts to fix my car. And the plot thickens.....Semper Fi

    "They do not have the necessary funds to provide this service and with the talk that they are going to dump around 1500 deealers, the GM service base is going to shrink as well."

    The way you make it sound, the number of "dealers" will be shrinking, but the "dealer service base" won't change at all, simply because you did not get much "service" until this last dealer
  • The time came to say sayonara to my Buick Losecerne CXS. I finally woke up and realized that the GM debacle was going to go wider and deeper and longer than anyone has owned up to. So rather than shoot myself in the foot once again (a court-martial offense), I decided to unburden myself of this heaving, vibrating hulk of an excuse for an automobile. I swapped it in on a 2008 Hyundai Azera Limited with the Ultimate Package. This Hyundai rides circles around the Buick (turning radius too) and drives like a Lexus ES350 at half the price. I did thoroughly research the car and found it to be highly rated by just about every reviewer which I read. As for the front end problem, it was resolved and any Azera with a build date after October 2007 was not having any of the difficulty which has been discussed in Edmunds and other sites as well. It cost me $118 to complete the transaction and a well spent $118 at that. The car handles, drives, and STEERS superbly. The Losecerne steered worse than an 18 wheeler with its gargantuan turning radius. And with the CXS and its wider wheels made this major flaw in the cars performance even worse. It was an unbelievable car to TRY TO drive. It was a nightmare what with its undulating and vibrating its way down America's highways and byways. And just a note to the contributor who maintains that there will be no decrease in the service locations for GM. Take a look at the abandoned buildings that were once thriving auto dealerships including their service areas. You will not see shuttered showrooms with thriving service areas alongside. The whole kit and kaboodle is shuttered and will remain so for the foreseeable future. Hence, you will have to arrange for service some place else if your dealer goes belly up thanks to a :Dear Dealer" letter from the General (Nuisance that is). So so long to this site and that poor excuse for a car that was once my 2007 Buick Losecerne CXS; I should have shot it and put it out of its misery. SemperFi

    Nice that you decided to resolve your anger. I suspect it was going to consume you no matter how the car problem was resolved.

    >drives like a Lexus ES350 at half the price

    You are aware the 350 is a Camry in drag. :sick: :P so saying your Azera rides similar to one is not a compliment.
  • bryangzbryangz Posts: 24
    That's a shame he got a bad Lucerne.

    The one we have is tomb quiet inside. It rides smooth and soaks up holes and bumps like they aren't there and for a big old boat it handles pretty good.

    While I wish it had a 5 or 6 speed auto, the 4 speed and the 3.9 V-6 are plenty powerful for me.

    Like, I think I noted before, I had to look up the 3.9 V-6, because it was so smooth, I thought it was a DOHC.....
  • plektoplekto Posts: 3,738
    My impressions of the Lucerne CXS were that it drove a lot like an older S420 - the big Mercedes tanks from a decade or so ago. But it wasn't quiet - it has a V8, after all. And it has the same gremlins all GM cars do in that it's not quiet - the power steering and hydraulics do vibrate and hum a bit, and the fuel pump is noisy at times.

    And the OEM ties were too directional and causing it to track the rain grooves on the highway. A bit of humming and vibrating as a result. The fix is, well, different tires. OEM shocks/struts and tires and so on are almost always cheap junk no matter what brand you're buying these days.

    Then again, it's a fine car. I think people are just expecting their cars to be like a video game or bank vault these days. Go drive an old 1960s Mercedes and try to hear yourself think. :P

    BTW, you want 4 gears with a V8. The bigger the engine, the fewer gears you need and want. 1 - because you're not drag racing it. and 2: You're not going over 80-85mph anyways. Less shifting/smoother ride and more hp and torque as well, since it's generally in its power band driving around town. Cheaper to fix as well.

    Small engines, otoh, do require more gears.
  • bryangzbryangz Posts: 24
    Just wondering if the base CX model has a quieter/smoother ride versus the CXS and CXL models with the stiffer suspension, bigger tires?

    The CX that I drive my mom around in is extremely quiet (it does have the ABS startup hum for a few seconds) and it rides smoothly with no vibrations.
  • imidazol97imidazol97 Crossroads of America: I70 & I75Posts: 18,312
    I wondered about the fuel pump noise. I haven't heard a fuel pump on any of my GM cars while driving.

    The CXS is much better tired. That does cause road noise.

    I suspect the softer tires on the base models are more what I would like.

    I'm not sure about the power steering humming. If that is during turns when the pressure is higher doing the assisting, the hose is probably out of place and touching the firewall transmitting the vibration of the pump. Not right.
  • plektoplekto Posts: 3,738
    Evidently the hoses do hum and vibrate, and that is heard and felt through the firewall/foot areas. It's a known "issue" that causes people to think there's something wrong. But nothing really is. The fuel pumps, well, they occasionally whine a bit but most cars do that now. The tires, being slightly more aggressive and unidirectional, plus lower profile, are noisier. When they hit rain grooved cement highways, they chatter and hum and pull a bit back and forth(tires want to drift, but each side is reversed so it pulls back and forth.

    This is tires. Put the normal CX/all seasons on it - something with a bidirectional non-"rain" type pattern and watch it disappear completely. When you go in to get the tires "replaced" - replace them with lower cost and higher profile(same as on the CX) tires.

    My theory is that the newer cars aren't ANY different than before. It's that the makers have gone to silly lengths to make them quieter and smoother, so any small gremlins that you never noticed before suddenly worry all the yuppies.

    The Lucerne CXS is the quietest and most insulated Buick ever. After driving my 1990s LeSabre the the dealer (at the time - now sold, good car) and immediately testing the Lucerne CXS, the CXS was Mercedes refined and quiet.

    Cars are noisy, clattery, humming, buzzing, vibrating things by nature. We just forget. Really. Go drive an old VW Bug and you come out half deaf, sore, and feeling like you've been working out with your legs and arms compared to say, a bog standard Focus.

    Case in point - my 4Runner has injectors that are as noisy as bad lifters or a tapping valves. Really. It happens when they are over 10 years old or so. The engine is so noisy at anything over idle, though, that I don't hear it at all 90% of the time.

    But put a sewing machine engine out of a Civic in it and it would probably drive me nuts. Heh.
  • imidazol97imidazol97 Crossroads of America: I70 & I75Posts: 18,312
    Fuel pump: I can hear it before starting the car, but driving with the blower on and a radio on, I'd never hear it. In fact I'll bet I can turn the accessories all off and not hear the pump on our paved road which is quiet pavement.

    The tires really make a difference. The standard leSabre has a General tire with high compliance to forces and very low rolling resistance. I always replace them with Michelins which are stiffer and give more road noise with long life treads.

    Current 60 profile on 225 X 16 inch wheels gives a more controlled steering reaction with the original SYmmetry by Michelin used on a lot of GM cars in 03. But when I replaced them with Harmony, they howl on certain concrete type road textures and a few other large pebble road mixes. But other times are quiet enough. I suspect a higher profile Harmony wouldn't do this on a 15 inch wheel on the same leSabre.

    I looked at a Sonata a couple years ago, and the model I'd want came with low profile tires on a large rim. Not what I wanted, both for noise and for replacement cost and life.

    Some of the automakers have really worked on minimizing the noises, like injectors, to help the quiet ambiance inside. Do I recall the Lucerne has layer side windows to help muffle sound?
