#13 of 61 Dead Battery Problem
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.

Doesn't your LeSabre have a power saver that shuts off power to accessories that are left on and will drain the battery (like interior lights) about 10 minutes after the ignition is shut off? I believe this is standard equipment. If so the problem is not a trunk light or glove box light that is sticking on. I agree, go to a dealer who is intersted in servicing Buicks instead of the one you are going to who only wants to sell them.
#15 of 61 Battery Problem

Thanks for all of your advice. We have had our Buick to two different Buick dealers to try and have our battery problem diagnosed. One dealer kept the car over the weekend looking for what was draining the battery but could not find the problem. The battery only goes dead once every three or four months so we think it has a short in something but all the dealers tell us is "we need to drive the car every day at least ten miles" or that we don't drive the car enough. We find this ridiculous. We have contacted the Buick home office but they say at this time they can't do anything.

Neighbor had trouble with Gran Prix Supercharged 3800 with battery draining. The car had an incident early with smoking wiring which dealer fixed, so neighbor thought drain was related to wiring problem.
But two batteries and lots of jump starts later, another neighbor who's a used car lot type repair what comes in mechnic's knowledge, replaced the starter. Replacement battery from Walmart and no more problem.
Somehow something on the starter was causing a drain that zapped the battery. Relay or ???? caused the drain. But it wasn't always happening.
#17 of 61 Dead Batttrey Problem
May 05, 2003 (4:44 pm)
A year ago I had a problem with a dead battery on my 2000 Buick Lesabre Limited. If the car sat for two or three days the battery would be dead. I took it to the Buick dealer. The problem was with the underhood light. They had to order one. Since then I have not had a problem.

I will try that. I disconnected the trunk light thinking that was the problem and put a mercury switch from the junkyard in. I since found out it was not it and it is on the battery saver program. We had another "incident" last week ago and mom had it towed to the dealer without me knowing. She insisted they put another battery in. I hope these ideas fix it.
#19 of 61 Battery Problem...that brings up a memory.....
May 15, 2003 (9:05 pm)
I had a chronic dead battery problem when I bought my 1994 LeSabre in 2000. All of a sudden, no more starting....I took it to two different places; one changed the battery and the other changed the starter. Problem persisted. Then I did a little diagnostic on my own and found that at one time the glove compartment wasn't shut properly because of too much stuff and at the other time, I had left some interior lights on. I started taking care of these little things and hasn't had a single starting problem in last nearly two years....and I live in cold Canada.
Buick has so many lights and so much of electronics, something gets left on and it is easy for battery to get drained.
#20 of 61 Engine won't crank on 2004 LeSabre
Jul 30, 2004 (10:29 pm)
We have a new 2004 LeSabre with 1200 miles. It would not crank and the dealer replaced the dead battery. That was two weeks ago. Two days ago it would not crank in the morning but it did in the evening. The dealer could not find any codes listed and would not replace the switch. My 2000 Impala had the same problem when new. Replacing the switch corrected the problem. Any other ideas on this one?

Went thru this with my 2000. I think it was my mom turning the key to accessory instead of off, thus draining the battery. With this model it is easy to do. It has not happened again since I showed her.
#22 of 61 Alternator problems
Nov 01, 2004 (10:58 am)
I have had 3 LeSabres and two Centurys. I replaced one alternator.
93 LeSabre 70K replaced. Still running at 150K.
98 LeSabre 120K -running fine.
03 LeSabre 20K - running fine.
89Century traded at 120K okay.
87 Century traded at 98K okay.
I thinks there's something wrong with certain Bonnevilles that causes alternator failure. Neighbor had 3800SC Gran Prix that had battery drains for 3 years. It had an alarm that seemed to drain the battery and something had burned up a wiring harness early in the cars life. REplaced under warranty.
But the neighbor, a shadetree mechanic who had worked with used cars all his life, changed the starter and the drain was gone... after 80K.
The neighbor's dad has a used car lot. He says 3800 in large cars is good for 300K. He sells a lot of used ones with high mileage.
