Consumer Description

Unknown PCV valve failure caused catastrophic engine failure on interstate highway (70 mph speed limit). Luckily there was room to pull to the side and no one got hurt. This part was recalled in 2019 models due to possible loss of control from engine failure. Dealer tore down engine to determine cause for possible warranty coverage and found the PCV valve was the cause of engine failure. There were no warning lights or indications of any problems before this.
