Volkswagen Tiguan back windshield wiper activates unexpectedly when engine is turned on on Volkswagen Tiguan

Some Volkswagen Tiguan owners report experiencing unexpected activation of the back windshield wiper when the engine is turned on. This issue may be caused by the rear window intermittent wiping feature overriding the system, which can sometimes be resolved by toggling the feature off and then back on. Additionally, some owners note that the windshield wiper system may have sensors that detect liquid on the windshield, triggering the wipers to auto-swipe for improved visibility. If the rear wiper activates without any fluid or pump sound, it could indicate a faulty switch or a more complex electrical problem requiring professional diagnosis. Furthermore, issues with the rain-sensing feature or settings in the vehicle's infotainment system might also contribute to this unexpected behavior. If these troubleshooting steps do not resolve the problem, consulting a qualified mechanic or Volkswagen dealership is recommended for further assistance.
