“In late May 2025, I took delivery of a new leased 2025 Rivian R1S equipped with the MaxPack battery. Since delivery, the vehicle has had intermittent electrical issues with the USB-C ports that I reported on June 12th (approx 3 weeks from taking delivery), but on July 28, 2025, it experienced a sudden and complete electrical system failure while parked. Both the high-voltage and low-voltage systems shut down, leaving the vehicle entirely inoperable. …”
NHTSA complaint #11679876, filed 2025-08“On January 9, I was driving my new 2025 Rivian R1S (approx. 2,400 miles) when it suddenly displayed “Drive stalk not working.” The vehicle jolted, made a loud noise from the front axle, and then fully stopped in the middle of a busy road with the battery still at 55%.

After several attempts to reboot, the screen showed “Critical battery error” before shutting down completely. I was unable to move the vehicle or alert other drivers with flashing lights, creating a major safety hazard. …”

The service center instructed to not drive it and eventually picked it up via tow truck and made repairs. The vehicle was returned and hot air successfully comes out of the vents but it is often accompanied by extremely loud noises (like a jet engine) as well as some pulsating and odd noises. …”
