#2 of 53 Dead Lesabre by kcwolfpack Nov 12, 2000 (4:47 pm)
I love this car. Engineering,ride and drive are superb. I would recommend this car to anyone in the market for a premium sedan. However,there are some annoying glitches which mine has. The worst one is a dead battery which happened twice in three months. the dealer says it was a bad cell. HAS ANYONE HAD THIS EXPERIENCE? It also had the dreaded kazoo windshield noise which was fixed. Now it is also making a popping noise from underneath the car, which I suspect is the exhaust heat shield. The car died and was restarted immediately once on a hot day. The people at my southwest Missouri dealership are first rate and are cooperative. I now carry walking shoes and a cell phone. When the battery goes, so does the standard OnStar. I also fixed a rattle in the dash by installing an old cut up windshield wiper blade between the windshield and the trim covering the A pillar. Thinking about an extended warranty? You bet.

I was interested in hearing that you have experienced the popping sound from under your 2000 Le Sabre. That is about the only problem I have had with mine. It has popped since the day I got it. I usually only notice it when I am first getting under way. It is more likely to happen when I change from one grade to another like entering the street from my driveway. You are the only other owner who has mentioned it as far as I know. I have been monitoring this thread for a year and a half. My dealer also thought it might be the exhaust shield but could not find anything unusual. I suspect it may be the self-leveling system but I am not a mechanic. It has not gotten worse over time. I am going in for my 15000 mile service next Monday so I would like to hear back from you if you have any more information.

Thanks for your quick response. I printed out the TSB data and will show it to my dealer on Monday. I will let you know how it turns out. I hope you get your electrical problem fixed quickly. I don't know how long you have been monitoring this thread but the dead battery problem has been discussed here from time to time.
#5 of 53 Battery by macarthur2 Nov 18, 2000 (5:29 am)
When two batteries go in a row it is definately time that a good mechanic was taking a good hard look at the alternator/charging system. Has anyone thought of that? You'll replace a lot of batteries until you check out the rest of the system. Two dead cells in a row? I don't think so. The odds are as good as Buchanan winning the election.
#6 of 53 Alternator trouble to report on 94 Ltd by jimsxn Mar 27, 2001 (10:59 am)
Car didn't start at all this morning..I had put a new battery just a month back. Upon investigation at Goodwrench, the alternator is down and would cost C$ 450 (USD300)to replace.
#7 of 53 jimsxn, alternator by tboner1965 Mar 27, 2001 (7:01 pm)
If it is anything like the alternator on my '87, it better not take more than about 10 minutes to change it. Mine sits right on top of the engine. Disconnect the battery cables and put it on a battery charger. (A really good way to ruin a new alternator is to immediately ask it to charge a dead battery.) Then, use a ratchet to take the tension off the drive belt at the tensioner pully, slip off the belt, unbolt the two bolts that hold the alternator in place. There should be a plastic connector that is easy to remove, and a wire on the back, held in place by a nut.   Take tha alternator down to the parts store and have it tested. If bad, get a new one. Have that one tested before you leave. Install in reverse order.   It will take longer to drive back and forth to the parts store than to actually do the work.   You can probably do this for $100US. Ask the counter guy for the best lifetime warrantied alternator and you should be all set.   Again, test the new one before you leave so you don't repeat the R&R.   TB
#8 of 53 lesabre tracking by kcwolfpack59 Apr 11, 2001 (9:10 pm)
mine tracks straight and true. I don't have to make as many micro-adjustments to the steering wheel as compared to other newer cars. however this car is more susceptible to crosswinds than my 97 Monte and the Olds 98 which was traded for the buick. I attribute this to the optional touring suspension in the Olds. I still am crazy about the lesabre and have not experienced the dreaded battery run down which I griped about in earlier posts. any new readers have this battery run down?
#9 of 53 by jimsxn Apr 16, 2001 (12:41 pm)
My battery change and alternator change were primarily initiated by a battery rundown...first time by a cellphone charger left in the socket and second time by a glove compt light. They were due for a change anyway so I don't mind as much..on the other hand they may have given more service. Beware of the lights left on....
#10 of 53 Buick Lemon by mbyrn Apr 26, 2003 (9:13 pm)
Our family has always bought Buicks and been Buick lovers until the purchase of our brand new 2000 Buick LeSabre Limited. We HATE this car due to mainly the constant dead battery problems. It is on its third battery and the car only has 18,000 miles on it. It also left me stranded in the middle of the street, downtown, on one occasion.(This problem did actually get fixed). The car has been to the dealer repeatedly to no avail. We only get the run around because they can't find what the real problem is. No more Buicks for us. Anyone considering purchasing one should have second and third thoughts about it.
