2000 Buick Lesabre engine complaints
Page 3 of 4: complaints 41 to 70 of 96, newest first, as owners wrote them.
Vehicle was having a problem with the catalytic converter. The mfr. Was unable to repair the catalytic converter because there were no parts to repair it with. Dealership does not know when the parts will be available for repair. *jb the vehicle was taken to the dealer in april but as of may 17 no new catalytic converter was available from gm to replace the defective one.
The front right bulb socket was so corroded it caused the bulb to stop working. *ph the right rear tail light stopped working. The consumer smelled anti-freeze after the recall for the intake manifold was completed. *sc
When the consumer started the vehicle it smoked from under the hood. Consumer turned the vehicle off, opened the hood, and noticed that intake manifold cracked and leaked fluid onto fuel injection, which caused the engine to catch on fire.
Service engine light came on. Dealer said code was an 0741 and 0743 showing electrical or possible tourque converter. Dealer said they were unable to duplicate. However it shuddered upon hard acceleration during merges onto freeway or turnpike ramps. The original estimate was about 3000.00. The garage finally had to take apart the transaxle to for a diagnostic.
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.
The vehicle would misfire and stall when reaching high temperature. The problem was due to an intake manifold defect. The dealer stated that they could not fix it because of high mileage. *ak there was leakage around the intake manifold, poor gas mileage and acceleration. *sc
While driving engine check light would come on intermittently.
Multiple defects with transmission, cruise control, fuel system, engine cooling, etc.*mr vehicle leaked coolant so the upper and lower intake manifold were replaced. In addition, the vehicle would lose power over 40-50 MPH. *ph
When the gear was shifted from park to drive the vehicle jerked with out warning. *jb the consumer was initially told the motor mounts were broken/weak, however the problem recurred, and the vehicle was taken back to the dealer, who then informed the consumer the wrong chip was used to control the idle speed. The problem was due to the type of emissions on the vehicle. Ph.
The fuel tank sending unit shorted out on both of the consumer 2000 buick lesabre's which resulted in inaccurate fuel reading. The rotors and gaskets also failed. The consumer requested reimbursement for the replacement of the sending units on both vehicles. *mr *scc

Upper intake manifold had to be replaced due to a coolant leak. This type repair appears to be very unusual for this age of automobile. Complaint submitted by family member.

Vehicle has an upper air plenum problem (oil leaking into the radiator).

Leaking coolant LED to replacement of intake maniford on 2000 buick lesabre with 3.8l engine costing $540. Newspaper article reporting that the federal safety agency is investigating this problem on gm 3.8l engines of specific years(1991-2000). Conversations with salesman and meachanics at gm dealership leads me to believe that this problem is serious and widespread.
Loud noise under hood at start up. Start up failed. Restart worked but a constant strong burning odor continued followed by fluid leakage. Took to local dealer ( worden martin buick in champaign, il. . They determined it was the intake manifold that required a $753.00 repair bill, since it was out of warranty. Dt
While traveling on the highway without prior warning. Flames were shooting out from underneath the vehicle. Please provide additional information dealer is aware of the problem. Ts
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.

Fuel tank and sending lines need to be replaced due to o-rings improperly fitted on fuel pump. In july 2000, vehicle was making a knocking noise when turning or going over a bump.
