NHTSA complaint #11565165

Owner complaint summary

Tesla vehicles have an automatic wiper mode that is supposed to clear the windshield, without driver intervention, when it becomes obscured due to rain, snow, or water buildup. While driving on December 19, 2023, our Model 3 was passed by a large truck, throwing a large amount of water across the windshield. When this happened, the forward visibility was completely obscured momentarily. The automatic wipers did not clear the windshield as expected. The vision was obscured until the driver was able to manually enable the wipers. Obviously, driving at highway speeds on the freeway, without being able to see forwards, even momentarily, is a safety concern. Thinking the car had a failure, we tried to arrange for a repair from Tesla service. Their response was: "This issue has been identified as a known firmware issue, to be resolved on a future firmware release. For now, we recommend using the manual wipers as needed when auto wipers are not detecting rain. When a fix is available it will be sent to your vehicle automatically over the air. Unless you had any other questions, I will go ahead and close out this service request. Thanks!" Looking through Tesla owner forums, this appears to be a much discussed issue for the last 4-5 years. Many owners are having issues with functionality of the automatic wipers. We don't have any photos of the incident, but I recreated a similar situation in a local touchless car wash. With the car being completely deluged in water and soap, the automatic wipers never came on. The included pictures show the touchscreen with the Auto wiper mode and the windshield completely obscured, but no wiper activation. The last photo is a screenshot of part of the conversation with Tesla support about the repair request.
