INFINITI Q50 engine limp mode and shutdown issue with no turnover after button press on INFINITI Q50

Some INFINITI Q50 owners report experiencing engine limp mode and shutdown issues, often accompanied by a reduced power warning light before stalling. These problems may stem from a malfunctioning transmission control board in the valve body, which can trigger a check engine light and shifting difficulties, potentially leading to limp mode. Additionally, specific error codes like p0011 and p0022 have been associated with the vehicle entering limp mode randomly. Furthermore, issues with the exhaust camshaft position sensor on the driver's side can disrupt the sensor signal input to the ECM, resulting in engine shutdown. To address these concerns, owners are advised to scan the vehicle for error codes to identify the root cause, consult their dealer about the transmission control board if under warranty, and investigate the exhaust camshaft position sensor to ensure proper engine operation.
