2025 Rivian R1S

Safety defect involving exterior rearview mirrors on Rivian R1S I am reporting a recurring and worsening safety issue involving the exterior rearview mirrors on my Rivian R1S Gen 2. Both side mirrors repeatedly lose their saved positions without driver input. More concerningly, on multiple occasions the mirrors have changed position while the vehicle was being driven, including at highway speeds. When this occurs, my rearward and side visibility is unexpectedly altered while driving, requiring me to readjust the mirrors and creating a significant safety concern. This problem has persisted across multiple Rivian software versions and has become progressively worse. I have already reported the issue to Rivian Service more than once. I have attempted to re-save the mirror positions, disable and re-enable Auto Tilt in Reverse, perform software resets, and recalibrate the system, without resolving the problem. The issue is not caused by Automatic Ride Height Adjustment, as it has occurred while that feature was disabled. I have requested that Rivian escalate the issue to its Engineering team and review vehicle logs, which should document the repeated changes in mirror position. Because the exterior mirrors can change position without driver input while the vehicle is moving, I believe this may constitute a safety-related defect affecting driver visibility. I am requesting that NHTSA review this issue and determine whether similar complaints exist involving Rivian R1S vehicles.

This complaint is associated with Complaint #11717398. My 3rd windshield has cracked after a tiny 1/8" impact point. The result was spidering all the way around the middle sensor housing area and propagating 6" down. It also spidered to the top of the windshield. This tiny impact shouldn't have caused a huge spidering effect. Whether from incorrect installation, car frame issues or defective windshield quality, this is my third heavily cracked windshield in my first 10 months of vehicle ownership. I'm heavily concerned about the safety issue from seemingly anything that strikes the windshield and the $2400 cost to replace each windshield. Thank you

Component/System: Visibility – Windshield. Was replaced in January 2026, not available for inspection. Pictures attached, doesn't include largest/spider crack on bottom of windshield that was 16" Summary of the Problem: I have experienced six separate windshield failures (cracks and chips) within the first eight months of owning my 2025 Rivian R1S. The most recent windshield was replaced by Rivian, and within five days the new glass developed an 7‑inch crack from an impact. The frequency and severity of these failures are far beyond normal road‑debris damage and strongly suggest a systemic defect in the windshield glass, installation method, or vehicle structure. Detailed Description of the Incidents: • Six cracks or chips occurred on the original windshield between the delivery date of May 20, 2025 and six months of ownership. • The first and 2nd chip was repaired by Safelite, the 3rd chip unable to be fixed at same time due to location at edge of glass. • Several cracks originated without any visible impact point. • The replacement windshield, installed by Rivian Service on January 21, 2026, developed a long crack within five days of installation. • Original windshield replaced and I submitted claim through insurance. I have appointment to replace second windshield on 2/16/26. Service representative at Seattle service center stated “to be transparent with you, windshields are customer pay as they crack due to outside influence”. This is after detailing the previous five separate incidents with original windshield and that the new windshield developed a large crack within five days of install on 1/21/2026. • All cracks/chips appeared during normal driving conditions. • The pattern of failures indicates excessive fragility, potential stress cracking, or improper windshield seating/alignment. • Numerous other Rivian R1S and R1T owners have reported similar issues, suggesting a broader quality or design problem.

After three (3) repairs, our 2025 Rivian R1S continues to leak all of its windshield wiper fluid when activated. This could be a safety issue if a driver's view is obstructed due to being soiled while driving. The washer function is necessary in these circumstances especially if drivers can no longer see what is in front of them. Someone could meet with an accident if his or her visibility is obstructed with no ability to clean their windows while driving. We have noticed several comments from other Rivian drivers who have experienced the same issue, leading us to believe that this could be a design flaw.

Winter weather led to snow buildup on the headlamps which made them useless. Fortunately this was during the day so there was plenty of sunlight. If this was at night, I would not have had any visibility and would have needed to stop every few miles to clean the headlamps. My BMW uses washer fluid to clean my headlamps and the xenon's are hot enough to melt snow. Neither of these are in the Rivian
