NHTSA Complaint #11510471 — 2023 FORD BRONCO

When attempting to use the wipers on low speed setting (constant on at a low speed, not on any of the intermittent settings) in medium and heavy rain situations, the wipers will initially operate at the constant low speed, and then after 1 to 2 minutes, the wipers will slow down significantly to a very low speed intermittent speed. The only way to get the wipers to return to the constant low speed setting is to switch the control stalk setting to high speed wipers and then return the switch to the low speed setting. Even when turning on the wipers at the high speed setting, the wipers will slow down significantly to a very low intermittent speed. This is a dangerous condition that creates issues in attempting to see during steady rain conditions.
