In moderate or even heavy precipitation the vehicle will reduce wiper speed from high or low continuous to intermittent, severely reducing and limiting visibility. I took it to Corwin Ford in Reno to fix this and they say that it does this on purpose and it is working as designed. Picture was taken while it was doing this, even with this much rain on the windshield the wipers won't stay in low constant and reduces the wiper speed to intermittent resulting in this level of visibility.

Windshield wipers stop moving at regular wiping speed. After a short time the wipers change from regular speed to intermittent speed causing loss of vision to the road ahead during rain and snow.

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.

Windshield wipers slow down when driving in rain/snow. Even on the highest setting, they start to slow down after a few minutes and you have to toggle them off and on again to get them back to normal speed.

Wiper motor does not stay on Low or High. Within a minute, they revert back to Intermittent and the driver must constantly switch between Low and High in order to keep visibility. This has been happening since the day I took delivery (in the rain). I will be contacting the dealer on 3/6 to discuss. Many others in forums have reported the same exact behavior. There has been no inspection yet. No warning lamps, etc.

Wipers automatically dramatically slow down when placed in the high setting during heavy rains causing unsafe driving conditions

I was driving in moderate rain today and had the windshield wipers in the low setting (continuous wipe, not intermittent). After approximately 60 seconds, the wipers stopped continuous wipe and I could not see. I switched to high, the wipers began working again so I switched back to low. 60-90 seconds later, the wipers once again stopped their continuous wipe, I could not see, so switched to high to get them working again. I continued my drive, having to switch the function from low to high to keep them operating. When the rain let up, I was able to see when the wipers quit and noticed they decided to wipe intermittently, despite being in the low (continuous) position. As my drive continued the rain let up a little, I switched to intermittent high (shortest delay). This function worked for about 10 wipes, then the delay increased and I couldn't see between wipes and had to manipulate the switch again to gain visibility of the road and oncoming traffic. To answer the questions I offer the following: 1. The wipers do NOT work in the position selected even if there is significant water on the windshield. 2. When the wipers stop working, you can't see out of the windshield. This requires constant manipulation of the switch, taking a hand off the wheel which endangers me, any occupants, and others on the road. 3. I have not gone to the dealer. I read the 25 page post on the B6G forum and found many others have experienced this as well and a link for this site to post the issue. 4. It has not been inspected by anyone. 5. There were no warning lamps, messages, or other symptoms. The vehicle only has 700 miles and this is the first time I've driven it in the rain when I needed continuous wipers.

Wipers run normal speed for 39 seconds and they revert back to five seconds in between wipes, no matter what the rain conditions or settings

Windshield wipers fail to maintain consistent operation. Cadence slows down on its own to an unusable speed causing unsafe visibility. Clearly there is something wrong with the programming.

- Lyons , CO, USA

When wipers are on they will intermittently stop even when in run mode. No change in how hard the rain is coming. Causes inability to see anything. Will sometimes start back up but usually can't wait that long and chandelier to fast mode to get them moving again

- Prosper, TX, USA

Wipers will slow down during constant on operation is selected, in low and high speed mode. They wipe as normal for 30-45 seconds, then start a slow speed wipe (in high or low, both slow to a crawl) for 2-3 wipes, then stop completely until the switch is changed to another setting. Then the cycle repeats. Makes driving in anything more than a drizzle challenging to see while constantly fiddling with the wiper switch.

The contact owns a 2023 Ford Bronco. The contact stated that while driving at an undisclosed during inclement weather, the contact activated the windshield wipers; however, the wiper blades started wiping very slowly until the wiper blades became inoperable. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 900.

- Arlington Heights, IL, USA

Wipers have some type of smart setting and the will actually stop working in heavy rain situations. Very dangerous configuration

- Morristown, NJ, USA

Wipers function for about 30 seconds on continuous, then go to intermittent, then stop. Does this at all speeds and all rain settings (heavy to light rain). Constantly having to turn wiper off and on to get it to function. Makes it difficult to see in rainy weather.

- Rancho Santa Margarita, CA, USA

The wipers slowed and stopped during heavy rain making visibility very poor. I had to manually turn the wiper speeds in order to see the road.

When wipers are on slow speed, after 17-22 sweeps will either stop, or to slow intermittant, does not matter on amount of water on the windshield. SSM FROM FORD IS NOT AN ANSWER. WIPERS SHOULD STAY

- Petaluma, CA, USA

After less than a minute of running, the wipers suddenly slow down to the lowest wiper delay setting. You notice because, if you're in a storm or rain, you suddenly can't see out of the windshield. It does this on all of the wiper settings. If you're in a bad storm and you have the wipers running on maximum, they suddenly stop and go to like a once every 30 second wipe. you have to constantly turn the wiper control back and forth the whole time you're driving to keep the wipers working.

- Oxford, MS, USA

So when wipers are on fast or slow constant mode that they slow down and go into a slow intermittent mode all on their own. After about 35 seconds the wipers start to slow down then after 50 seconds they stop causing a serious safety concern. This has now happened several times. I was unable to see in front of me and almost hit another-??s car. There were no warning lights. I am taking to a dealer next.

- Molino, FL, USA

Windshield wipers when turned on will work and after a few seconds begin to slow, then go to working intermittently and then go to swiping like once every 5-8 seconds. When I reset the wiper it will do it all over again.

High speed wiper setting runs fast and then becomes extremely slow requiring driver to twist down and back up to reset to high. This is a safety hazard
