2001 buick lesabre custom: 40 mph..shuts off with no warning..coasting

Customer Question

My 2001 buick lesabre custom has died five times while i was driving in the past week. I'll be going 40 mph or slower and it just shuts off with no warning. I'll be driving the next thing i know i'm coasting down the road with no power. It will start right up after i stop and put the car in park. I have no idea what's going on.

Hello & Welcome to JA,

John :

This 9intermitten) problem can be hard to track down.i have found faulty crankshaft sensors on these engines ,many times.The fault does dot occur long enough for the computer to set a failure code usually.Replace the crankshaft sensor.

John :

(intermitten) , sorry for the typo.
