Rivian R1S Problems by year

without touching or activating the harness-release button. The shoulder straps lengthened relatively easily, while the front tightening strap retracted back into the car seat. This demonstrates that the harness can lose tension without the release mechanism being intentionally activated. I also own an older Nuna RAVA car seat used by my daughter, and I have observed similar harness-loosening behavior with that seat. I am particularly concerned because my son's car seat was manufactured after the October 25, 2023, cutoff associated with Nuna's previous RAVA harness-adjuster recall. My son's seat has the newer fabric-covered harness-adjustment design, yet it exhibits similar symptoms. This creates a potentially serious safety risk because a child can unintentionally or intentionally loosen the harness while riding, leaving excessive slack that could compromise the restraint system's ability to protect the child during a collision. I have video documentation demonstrating the harness loosening without pressing the release button, as well as photographs of the adjustment mechanism and manufacturing label. I am requesting that NHTSA investigate whether the harness-adjuster defect identified in the earlier Nuna RAVA recall may also affect newer car seats manufactured after the recall cutoff. I believe this warrants investigation because the issue is reproducible, occurs during ordinary child behavior, and involves a critical safety component.

also detached while tightening the bolt with a standard hand wrench. The bolt initially turned normally before encountering resistance. No torque measurement was available. Two separate captive nuts have now failed, leaving the passenger seat improperly secured to the vehicle floor and creating a significant occupant safety concern, particularly during a collision. I am concerned about the integrity of the captive nut attachments and whether this represents a manufacturing or assembly defect. The cause has not yet been determined. I request that NHTSA investigate whether similar seat anchorage failures affect other Rivian R1S vehicles. I am also requesting a manufacturer-approved structural repair and engineering evaluation from Rivian.

replaced the 12-volt battery, and updated the firmware. The repair invoice does not identify a root cause. This failure happened while the vehicle was parked. If the same low-voltage failure occurs while driving, the driver may lose the ability to select or maintain a drive gear and may lose warning and status information, with no prior warning. That creates a risk of a stall or loss of propulsion in traffic. The electrical, software, and display problems began much earlier. On [redacted], the center display screens went blank and would not power on; a soft restart helped only temporarily. On [redacted], the Rivian app stopped communicating with the vehicle and the vehicle's software would not update. Rivian confirmed a service appointment on [redacted], and in [redacted] (36,778 miles) found the vehicle had been offline for about two months; the repair required disabling 12-volt power and updating firmware. In [redacted] (44,779 miles) the screens again would not power on. Rivian logged an infotainment control module (XMM) board over-temperature fault (DTC B21014B), found the coolant well below the minimum line with air in the thermal system, and drained and refilled the coolant. The displays show gear selection, speed, warnings, and camera views, so blank screens remove information the driver needs. I am concerned that the root cause of the electrical failure has not been found and that it may recur while driving.

repeatedly. Even after I manually dismiss the advertisement, it returns when I reenter the vehicle. Rivian is effectively forcing me to clear an unsolicited commercial promotion to access a camera display essential to safely backing up. This is an entirely unacceptable design and safety failure. Rivian should be particularly sensitive to this issue given its recent federal safety recall, NHTSA Recall 26V-597, involving software notifications obstructing rearview-camera images. That recall specifically addresses compliance with Federal Motor Vehicle Safety Standard No. 111, which governs rear visibility. While the Ghostbusters promotion may involve a different software condition, the safety concern is substantially similar: a driver shifts into reverse and cannot see the required rearview-camera image because an on-screen notification is obstructing it. The fact that this obstruction involves a commercial entertainment promotion rather than an essential vehicle notification makes the situation even more troubling.

vehicle in Park; after a vehicle reboot, we were able to shut it down. After stopping, we discovered that the accelerator pedal had become physically lodged beneath the driver's all-weather floor mat, holding the accelerator down. The mat supplied for the vehicle was a previous-generation mat rather than the mat intended for the 2025 Gen 2 R1S. Rivian warns that 2022-2024 floor mats can potentially interfere with the accelerator pedal when installed in a 2025 or newer vehicle. Immediately after the incident, I used the vehicle's native Rivian AI functionality twice to request diagnostic evaluations. Since the incident, the conventional brake pedal feels weaker/spongier than I recall previously. Rivian is scheduled to inspect the vehicle October 12, 2026 under Work Order 000002609847. I provided Rivian photographs identifying the incorrect mat and photographs showing smoke from the wheel areas. Original in-cabin smartphone video recorded during the incident has been preserved. No collision or physical injuries occurred. I am reporting this because a manufacturer-supplied incompatible floor mat physically trapped the accelerator during highway operation, creating a risk of sustained unintended acceleration that could affect other 2025+ Rivian R1 owners.
