 Transmission no longer shifts into 3rd or overdrive. with shifter in overdrive and in stopped position once you take your foot off the brake to begin acceleration the torque converter slams to a stop and the engine shuts off. transmission fluid full at all times, engine warmed up. repeated stalling, repeated tachometer quits. repeated engine quits when you place in overdrive from neutral. must start movement by placing in lower gears 1 2 or 3. this transmission never shifts out of second gear. put it on code analyzer and got 2 codes that indicated pc solenoid torque converter solenoid issues. seems like these 2000 buicks have reoccurring defects and gm won't standby their product. why on earth would a company that designs cars ever put a battery under a car seat. one spark with hydrogen gas under that seat could kill an infant in a car seat if it exploded.. come on!!

 On june 25, 2010 approx 8:30 pm our 2000 buick lesabre was sitting by our house, not running, no keys in it. we heard a huge bang/backfire. the car had been parked since 4:00 pm. we saw a huge amount of smoke and fire as high as the porch deck roof. immediately called 911. the hood was blown apart, the windshield blown in, rear view mirror & visors blown off. the car was completely totaled; everything on the engine melted, radiator gone, tires melted & tire rims look like they were blown outward. it was a very hugh explosion & we did find the odi report ea 02-030 for recalls #03034 & #03054 for explosions/fires in this buick. the recalls for our vehicle were completed and done in 2005 for the above items of fuel regulator causing defective/leaking fuel reg asm etc. or coolant causing improperly seal throttle body this vehicle was always a good running car with few problems and a car should not blow up just sitting still, so obviously the problems were not sufficienly corrected. the only event before this was that when the ignition was turned off at 4:00pm the passenger door lock was clicked at the same time and we heard a big clunk kind of sound. our mechanics who viewed the vehicle and all who saw it never saw something that bad and all said that we would most likely have been killed if we had been in the car when it blew up. the vehicle is presently still sitting in the exact spot where it blew up as requested by gmc, but it will need to be moved before snow plowing as it is 6'6 from our house steps and is a hazard to our residence. we told gmac that we would be removing it before aug. 30th, however, they have not inspected it as of yet. other property damage includes melted vinyl siding on our home, damage to deck paint, much needing power washed & damage to tar driveway, plus soot damage. have many pictures, if you have e-mail address.

 Coolant leakage from coolant resevoir into air intake manifold. it is obvious that engine coolant drawn into cylynder head can have numerous results damaging to the operation and longevity of the engine. further the loss of coolant form the resevoir can result in inadequate engine cooling and high and destructive engine temperatures. while there was no observed evidence of coolant loss before gmc recall to tighten throttle body bolts, the loss of coolant accelerated after the unsuccessful effort to eliminate coolant loss. that this problem has been present since early in 2000 model of the buick lesabers is evidenced by complaints and service reports. the recall program of summer 2003 was an inadequate solution to the problem. in addition to this history, the existance of long standing problem is confirmed by gmc's recall in the summer of 2003. my complaint is heightened by the fact that both the dearler and gm refused to investigate the coolant loss observed after the recall as a part of the recall and used the expiry of my original warranty after the recall announcement and also after the completion of recall servicing without fully charging me for the investigation and required remedial work to resolve the coolant leakage malfunction. during my research into this situation i encountered a mr good wrench who worked in service department of a large buick dealer. while discussing the throttle body leakage, he commented the buick has an even bigger problem with the plastic section of the intake manifold which is encountering frequent cracking of this section of the manifold resulting in loss of coolant and major engine operation difficulties. sounds to me this problem which is even more damaging and expensive to consumer than the throttle body leakage merits an investigation.*ak

 I had at least 6 different times that i would go to start the engine and it would only hum, not start. i took it to the dealer while under warranty and they said they could not duplicate the problem. i asked if they checked the battery cables and they said yes. i asked this as i thought that was the problem, a loose battery connection. i knew they did not check, as the battery is under the rear seat and i placed a kleenex box in a marked position and it was exactly the same when they returned the car. it finally just wouldn't start at all, so i had it towed to a repair station (not the dealer) to be fixed. they said the battery cable was loose and arking and they were surprised that i didn't have a fire under the back seat. the reason for my complaint, i don't want anyone injured or killed from a fire under the rear seat in any 2000 buick lesabre. hope you will make gm check all battery connections on any model with the battery under the back seat. thank you.*ak
