Buick Lacrosse owners have reported 1 problem related to crankcase (pcv) (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 Lacrosse based on all problems reported for the Lacrosse.
There is a known issue with this model as well as other 2. 4 litre gm engines where the pcv valve may become clogged and if it is not fixed it can cause the rear oil seal to be damaged, hence rendering the engine useless. There is a special coverage bulletin that cover this vehicle and others under certain VIN numbers. However my vehicle had the same issue and is over $1`,000 to diagnose and fix. After talking to Buick, even though I am within coverage dates and well below the mileage, my vehicle does not qualify for repair and I must pay for it out of pocket, despite it being a known issue in other vehicles. This should be moved from a special coverage to a recall for any affected vehicles under the 10 year, 120,000 mile threshold.
