NHTSA Complaint #11558502 — 2023 FORD BRONCO

While driving at multiple different speeds in the rain and snow, the wiper blades on the vehicle slow down on their own to an intermittent speed without driver input. This slowing of the wiper blades causes the driver to lose visibility while driving, creating a safety hazard on the road. This issue has occurred numerous times when the wiper blades are set to the highest speed. After about one minute, the wiper blades start to slow down and eventually reach a stop/start speed where the blades only wipe every 5-10 seconds. To remedy this, the driver has to turn the wiper blades off and turn them back on again to get the wiper blades going again at the higher rate of speed. However, this only lasts for a short period of time (about one minute) and then the wiper blades slow down again on their own. The driver has to keep repeating this to be able to maintain visibility while driving in rain and snow conditions. This causes the driver to have to take a hand off of the steering wheel in inclement weather to keep adjusting the wiper blade speed. This issue has not yet been taken to a dealership for inspection, but this issue has been referenced in several online forums for this particular vehicle. There were no warning lamps or messages that appeared on the vehicle. In fact, in online forums, other Bronco customers have stated that Ford says this is how the wipers are supposed to operate.
