 In december 2010 i had my 2001 buick lesabre repaired at schepel buick in merrillville, indiana. they replaced the intake manifold gaskets and the thermostat because of the coolant leaking. i just found out the gm knew of this problem with the dex coolant for a long time and didn't let anyone know. i called the service manager a schepel bill and talked to him and he said that he never heard of this and neither did gm. its all over the internet. he lied to me. he told me not to believe what the internet says. i am out $779.45 for something that they should have paid for. the never had a recall because they wanted to keep it quite. i just don't think that they should get away with keeping it quite when someone could get hurt and to avoid paying for their mistake.

 Oil leak on 2001 buick lesabre. not only was leaking from sending unit, but from valve covers. obviously is leaking on engine, as i smell hot oil and at times see smoke coming from under the front hood. a recall: ea07008 nhtsa action number: ea07008 has been issued for various gm models including buick regal, all with the 3.8 engine, however the lesabre is not listed. this aforementioned recall indicated that this could cause a fire in the engine compartment, so considered a safety issue. *tr

 Engine: oil leaking somewhere, as smell the hot oil and sometimes smoke comes out from under hood. local service determined main leak was oil pressure sending unit and additional leak from valve covers. repair cost for just oil sending unit: $167. the cost estimate for valve covers: ~$300. decided to forgo that for now. *tr

 I am trying to get information on a recall for my 2001 buick lesabre. i spoke with buick and they acknowledged there was a recall for engine coolant leaks, but apparently being the second owner of the vehicle i was not notified. i am now having problems with engine coolant leaking into the motor. i have 73,000 miles on the vehicle and the dealer states it is age and mileage. i am not sure!!!!!! i feel if there was a recall due to a defective gasket which caused these leaks then i should be covered under that recall??? from what i could learn from your site buick had a recall for their regal and pontiac grand prix. it is gm recall. #07035. i know i have a lesabre,but it seems to be having the same problems. is there a recall on my vehicle also??it supposedly is affecting over 20,764 vehicles and the 2001-2003 models won't be notified right away. prior years were notified april 2008. i am a second owner so not sure if i would ever be notified. please advise. *tr

 Throttle valve plate sticking. the gas pedal has to be stepped on hard when you first start up after setting a while. i'm told this is a common problem with the unit uses on many of their vehicles mine is on a 2001 buick lesabre with a 3800 engine. waldecker pontiac, brighton, mi told me this item wasn't covered on the extended warranty i purchased (6yr/100000 mile) i had 94,000 miles on the vehicle but the problem has been around for at least 10000 miles. i now have 101600 i'd like to know why it wasn't a warranted item. this also could be construed a safety item as when you step hard on the pedal the car surges forward slightly. i'm aware of it so i automatically hit the pedal and release. *jb
