Subaru has issued separate recalls for the Subaru Crosstrek and Impreza as a result of two engine issues, according to documents filed with the National Highway Traffic Safety Administration. The first, which includes 466,025 Crosstrek and Impreza models, is related to a buggy engine control module, which affects 2018-2019 Crosstrek vehicles and 2017-2019 Impreza models.
According to the documents filed on October 18, the ECM may continue powering the ignition coil after the driver shuts the vehicle off, which can lead to a short circuit and a blown fuse. If a short circuit occurs while driving, the driver can unexpectedly lose power and the engine might not restart straightaway. This can increase the likelihood of a crash. Subaru said that among the warning signs, drivers should be aware of irregular vibrations and cylinder misfires while the engine is running.
The recalls cover as many as 466,205 late-model Imprezas and Crosstreks, Subaru said in a statement to the National Highway Traffic and Safety Information Administration https://t.co/d59bd4FerV— CNN (@CNN) October 25, 2019
Subaru says updated ECM software will resolve the problem; therefore, owners should bring their vehicles to a dealer to have the software installed. During the visit, a technician will also review the ignition coil and switch it if needed. Vehicles with confirmed ignition coil damage will also be fitted with a new front exhaust pipe. The repairs and work are free of charge.
The second recall is related to a separating positive crankcase ventilation (PCV) valve, which may deposit debris into the engine. The recall, which was filed on October 17, affects 205,000 2018 Crosstrek and 2017-2018 Impreza models.
If the component separates, it will flood the combustion chamber with engine oil. Owners may see increased amounts of exhaust fumes from the tailpipe. In addition, if the PCV valve keeps shifting and separating, pieces may enter the engine and result in the Crosstrek or Impreza losing power, which can also increase the risk of a crash.
Owners affected by this recall should have a technician inspect the PCV valve and replace it. Once the new part is installed, the technician will check to see if it also separates, in which case the separator cover and oil pan will need to be removed. If the separated parts aren’t visible during inspections, Subaru will replace the short block engine at no cost to the owners. Both recalls will begin on December 13.
