A new fix is still being developed.
BMW vehicles affected by the expanded recall are certain 2008-13 128I vehicles; 2006-12 3 Series models; 2006-10 5 Series vehicles; 2007-10 X3 SAV models; 2007-10 X5 SAV models; and 2006-11 Z4 vehicles.
The recall also includes 98,000 vehicles in Canada and 18,000 in South Korea, a spokesperson told Bloomberg.
In a recall report submitted March 2 to NHTSA, BMW said the affected vehicles contain a Positive Crankcase Ventilation, or PCV, valve heater that "may not have been produced by the supplier to specifications."
Part irregularities could lead to a short circuit and cause the PCV valve heater to overheat, increasing the risk of a fire.
German auto supplier Mahle International makes the PCV valve heater.
"Smoke may be noticeable from the area near the engine compartment," BMW said in the report. "A plastic burning odor may also be noticeable."
The expanded recall “includes certain model year 2012 and 2013 vehicles not previously recalled and re-recalls many of the vehicles previously named in the 2017 and 2019 campaigns,” Jay Hanson, BMW’s product and technology spokesperson, said in a statement to Automotive News.
“However, it also removes a number of vehicles from previous recall lists because they were produced with a different, more robust PCV valve heater design.”
Hanson said the new remedy and a sufficient inventory of parts are expected by mid-2022.
“In the meantime,” he said, “as the likelihood of failure is extraordinarily remote, customers may continue to drive their vehicles.”
BMW has not received any reports of accidents or injuries related to the issue, according to the report.
Dealers were notified March 2. Vehicle owners will be sent notification letters starting this month, Hanson said.
