Buick Lesabre owners have reported 19 problems related to check engine light on (under the engine and engine cooling category). The most recently reported issues are listed below. Also please check out the statistics and reliability analysis of Buick Lesabre based on all problems reported for the Lesabre.
While driving the vehicle at 35 mph, the dashboard check engine light illuminated. The engine idle speed became erratic and the vehicle stalled. Upon scanning the computer for fault codes, a p0102 code was found. The mass airflow sensor and the idle control valve were both replaced, however the p0102 fault and check engine light re-appeared the next day. I have found hundreds of complaints online for the identical problem that Buick Lesabre owners are experiencing with no solid "cure" for the problem. This condition is un-safe and renders the vehicle unreliable for driving.

The check engine light came on in my 1998 Buick Lesabre and I pulled over to discover that there was low levels of coolant. It had just been checked 2 months earlier at an oil change and the week brfore when I got gas. I added coolant and got back on the road. After 5 miles the car quit running in heavy traffic. I had it towed to a Buick dealer who diagnosed the problem as a failed plenum that allowed coolant to foul the plugs. The dealer replaced the plenum, fouled plugs, coolant, and oil for $800. 00 dollars.

While driving on my way to work the vehicle started to slow and the engine light came on. I pulled over and attempted to start the car and the engine would not turn over. I called my auto club for a tow and the car was towed to a connoco station in park rapids. They immediatly knew what the problem was, stating they see a lot of the 3800 engines do this. The intake plenum rotted away allowing coolant to fill a cylinder and stall the engine. Gm has issued a service bullitin for the problem, but no recall. This could be a major safety concern with loss of power to the engine the steering and brakes will not function as they should.
