Powertrain requires service
Avoid hard acceleration
An issue has been detected in the powertrain system.
The vehicle is OK to drive, but you should schedule
service as soon as possible for a powertrain inspection.
Your vehicle has detected excessive backlash (lash)
between the drive unit and the wheels. High, or
excessive, lash is indicative of mechanical wear.
There are many possible causes, so a powertrain
inspection is needed.
Your vehicle is OK to drive to your immediate
destination and to a service center. Avoid hard or heavy
acceleration, as this puts more stress on the powertrain.
Schedule a service appointment at your earliest
opportunity. If this issue is not addressed, your vehicle
might unexpectedly stop while you are driving.
