Buick Lucerne: Engine & Performance

    You don't say if the Lucerne is new or used. Is it under the 4-year warranty or 50,000 miles, which I think is the warranty now?

    Is it oil? Or coolant, which is orange and can feel oily to the touch.

    It could be an oil filter seeping slightly or a drain plug on the oil pan seeping.

    I'd check with the dealer.
  • I am pretty sure it is oil. They are just two or three so0 it might not be
    serous. The car has 20,000 miles on it.
    Have owned two parl avenues in the past and loved them.

    Also might be power steering fluid which is clear and a mineral oil if I recall. It has no smell.

    I'd put a newspaper or white paper under the car where the drip occurs to see the color of the drip and the consistency. Also look at directly above the drip on the motor to see what parts are in the area so you can tell the dealer under which part of the motor the drip "appears" to be falling--sometimes the drip travels from where it starts before it falls off to the ground!
  • I took it to the dealer and found out it was the right drive seal.
    They are going to fix it under the warranty so it turned out fine.
  • I took my Lucrene to the dealer and they fixed the leak. It still has some warranty left. We took a short highway trip yesterday and I
    love the way it drives on the highway just smoth as silk. Sometime
    will have to take a longer trip and see what kind of milage we get.
    The onlu compalints I have is I'm 6'4'' tall so I can't see all the rear
    view mirror and the headrests are righ aganist my head. It's not bad
    so I can live with it. The color is dark crimson mettalic and am in the
    process of waxing it. Is'nt pretty the way water beads on it. Never
    thought I would have so much fun waxing a car.
  • In November I bought a new 2009 Buick Lucerne because I had such good service out of my 1997 Buick Riviera. I am now thinking I might have made a mistake. The Lucerne apparently has an oil leak. The dealer put a dye in it the other day and is going to check it out Tuesday. When standing under the car looking up, the oil is in the corner of a square area beside the oil pan. He said the gasket may have had a nick in it when it was installed. I am worried that this will be an ongoing problem with this car. Does anyone know what the chances are that this can be corrected and not happen again for many, many years or is it most likely going to be a problem always? The car has 1300 miles on it. I am so disappointed because I really like this car.

    If the issue is a simple gasket, and the dealer properly repairs it, the problem should not recur for several years (if at all.) Now if your leak is massive, and is resulting in quarts of oil being lost in a short amount of time, that would be very concerning and may indicate other issues.

    I wouldn't allow this seemingly minor issue to ruin your enjoyment of the car. It sounds like the dealer is working with you, which is a good thing. Your car is only 3 months old. Make sure you document all visits related to this issue. In the event the dealer cannot completely fix the problem in 3 or 4 visits, you could always look into the Lemon Law in your state.
  • Ryster, thank you for the encouraging words. The dealer is a very reputable dealer and I had no doubts they would fix the car, if possible. It did put a little scare in me since the car was so new. The oil pan gasket was replaced on 1-22-2010 and I have not seen any more oil, yet anyway. I hope that was just a fluke that is now fixed for many, many years. I still really like this car a lot.

    Has anyone had experience with coolant loss? Had this problem on 97 park and of course it was the plastic plenum. My Lucerne has 61,000 mile and seems to have lost about 2to 3 quarts of water from resivor in last 1000 miles. My engine has an aluminum plenum. Dealer has not seen this problem in these cars. Any help would be appreciated.

    The 06 Lucerne I just bought has the rear end bobbing slightly up and down on the highway. It only has 10000 miles on it so I don't see how any shocks can be worn? Does anyone else feel this in theirs? It does have a trailer hitch on it, but I have no idea what the previous owner pulled with it. Anyway, with such low mileage it shouldn't matter.

    My other problem that I had concerning the knock or click in the steering wheel when I made a slow turn was fixed. The mechanic knew exactly what it was, the intermediate steering shaft. He told me they had been putting cheap shafts in them since 1999, hence the trouble with my Intrigue and now my 2009 Lucerne. They replaced the shaft and as far as I know that fixed the problem. Now I have a different problem. Situation: I am stopped at a traffic light or stopped any place such as this(foot on brake and car in Drive). I can feel a strong vibration with my hands on the steering wheel. Took it to the dealer. Went for a test drive. Couldn't get it to do it. After a few days went back to the dealer. Stopped in front of the service entrance. The steering wheel was vibrating. Called the service desk. Asked someone to come out and verify steering wheel was vibrating. It was verified. Made an appointment. Took it in to be fixed. They adjusted the cradle forward. They said it was better. Service person said he would call in couple days to see how it was doing. I drove it about a half mile. Stopped at restaurant. Vibration was as strong as it was when I took it in. Went on home. Waited several days for the service person to call to see how the car was doing. Never did call, so I had to call him. Told him there was no improvement. Made another appointment. This time they adjusted the shaft, changed the harmonic balancer, and changed the drive belt. I also had a small oil leak, so they had to replace the timing cover oil seal.Service person called and said car was ready. Said they thought it was better. I live about 12-13 miles from the dealership, the two times I had to stop, I hadn't gone very far and the car hadn't warmed up it. I didn't feel any vibration. I thought, yeah, maybe they have fixed it. I didn't have to stop again until I pulled into my garage. What a downer, the vibration was just as bad again as the other times. Being as the 2009 model has a new engine in it, 3.9 instead of the trusty ole 3.8, there is not much feedback yet and they were having problems getting information on what the solution to the problem was. I was wondering if anyone on this forum has any information or ideas what is wrong. I would really appreciate it. Thanks

    This is just an amateurish guess, but based on a similar experience I had with a 2007 Ford Taurus, check to see if the electric fans that cool the radiator are kicked on when you feel the vibration. When the fans are not on, the vibration should be gone. Perhaps one of those fans is out of balance in some way. Hope the idea helps.

    Lonclip has a good point. I had a Buick which had a rougher idle when those two cooling fans kicked on--under some conditions.

    It may be so many things in a new application of a motor. Is it different in reverse than in forward, even with the car stationary? One thing that does happen is power steering tubes or other connectors on an engine transfer vibration to another part which can be felt inside the car. I do not know if your Lucerne has electric steering, but there might be other items that transfer movement.

    And it may be motor mounting which is what they're working at changing.

    My Lucerne started to have a small leak at about 13,000 miles.Been to dealer three times and the leak is still there.They replaced the harmonic balancer and seal on the first two trips to the dealer.The last time they resealed the seal that did not fix it.I have the 3.9 V-6. I'm open to any help on what to do next.
