Two problems related to engine shut off without warning have been reported for the 1998 Buick Lesabre. The most recently reported issues are listed below.
I came home after bible study on Wednesday night and got up Thursday then the security light went blinking. My husband had the key ignition replace then brought new key but car still wouldn't start so had the car towed and repaired. 10 months and three weeks the car did the same but I was driving this time and it shut down in the road with me and my children. It was frighten but we made it safely out of the road before anything happen. I don't understand that this problem occurred again . I am upset about the problem. A car has no business shutting off in the road while a person is driving it accident or no accident because it in danger peoples life. A serious problem for many people whom have these cars made by gm.
While backing out of the garage and driving down city streets suddenly and without warning vehicle just shut off. Contacted dealer, and he was not able to find the problem.
