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.

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.

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?

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....

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.
#11 of 53 Possible dead battery solution by kcwolfpack59 Apr 26, 2003 (10:29 pm)
Make sure the your ignition switch is off. It is much easier than other cars to turn the switch back another notch to accessory. My mom has a problem with that and when it happens, it takes a day for the battery to run down. Since your problem is happening downtown, I assume you have not left it for more than a day and you would take your keys with you, eliminating the cause of the problem I am having. Please post your fix here. I am still a little worried about this. Otherwise I still love this car.

Sounds like you're still under warranty. If the dealer hasn't diagnosed the problem, why haven't you been to another Buick dealer. In three years I would have been sleeping on the service manager's desk to get it fixed. You didn't say what was the problem that was fixed...   Have you contacted the Buick 800 number????   Your dealer should have kept the car for several days while giving you a loaner to drive. During that time they could have looked for a drain on the battery or alternator problem. You have a dealer problem, not a Buick problem. You could insert any favorite name here, Lexus, Honda, Toyota, Infinity, Volvo, etc., and they could all have the problem with batteries.   Come on here. Let's not be so brutal on the brand, when it could be any car having that kind of trouble.   Good luck. And try another dealer while you're under warranty especially.
#13 of 53 Dead Battery Problem by mrpoetryman Apr 27, 2003 (7:15 am)
I agree with imidazol97. I also have a 2000 Buick LeSabre limited with 42,000 trouble free miles on it. I have had no problems with my battery. I would definitely go to another Buick dealer and let them keep the car as long as it takes to find out the cause of the problem. It could be as simple as a loose wire somewhere that is draining the battery. Your car is still under warranty, so you have nothing to lose. Good luck and let us know what the problem and solution are.
