1999 Buick LeSabre Problems

Engine -- Verified

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

Engine -- Verified

The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.

Heating & Air Conditioning -- Verified

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

Drive Train -- Verified

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

Engine -- Verified

The water pump may develop a coolant leak resulting in an engine overheating condition.

1999 Buick LeSabre Reviews

This has been a great car. Bought it in 2001. No major problems other than rotine maintenance.
Just had it checked at my garage. Paid $69 for used car safety check to make sure everything was OK. I needed a serpentine belt replaced ($260) and that was it.
Looks like I'll be driving this car for awhile longer.
