For scale, 543 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year and 7 months.
Defect
In the crankcase ventilation system, the bending process parameters used to form the PCV valve are not appropriate for the material's characteristics, leaving the crankcase connection point with insufficient durability. Failure of the connection allows engine oil to enter the combustion chamber, where it burns and produces large amounts of white smoke from the muffler. In the worst case, the engine may stop while the vehicle is in motion.
Corrective action
Replace the PCV valve on all vehicles with a corrected part.
