There are 1 owner-reported engine complaints for the 2025 Rivian R1Sin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
On November 16, 2024, while trying to use the vehicle's heating system, only cold air would come out of the vents and an error message, “thermal system fault” appeared on the screen. 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. Also, periodically only cold air comes out of all vents (even though the screen shows heat) if the defog is selected with temperature and fan speed regulated. The safety and performance of the battery has been impacted by the faulty thermal management system.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
