Five problems related to engine stall have been reported for the 1998 Buick Lesabre. The most recently reported issues are listed below.
On 07/21/03 my 1998 Buick Lesabre (VIN 1g4hr52k6wh425412), suddenly and without prior symptoms, began to run extremely rough and the engine stalled and was unable to be re-started. Fortunately, I was able to get off the road before the engine stalled. I am now saddled with a $2,000 repair bill all, apparently, as a result of the failure of the plastic gm plenum. The plenums failure caused other failures within the engine (including, but not limited to, the ignition control module and the starter). According to the mechanic that serviced the vehicle, this is not uncommon in gm vehicles that utilize the plastic plenum. I would seek restitution from general motors for what appears to be a historical and systemic failure of this plastic plenum resulting in extraordinary engine repairs.
