## NHTSA's summary

Service Update \- Certain 2020 model year Cadillac CT5 vehicles had the incorrect torque applied to the starter nut. \(6Nm instead of 12Nm\). The nut may loosen over time due to insufficient clampload. This could cause intermittent start issues, a no start condition, or prolonged crank times. Arcing or sparking may also occur. Dealers will tighten the starter nut to 12 Nm and replace any parts that show arcing.
