Rivian to replace faulty onboard chargers on R1T and R1S

Rivian has launched a customer satisfaction campaign after becoming aware of an issue with the onboard charger on the R1T and R1S. In affected electric vehicles (EVs), owners are unable to charge on alternating current (AC), or in other words on Level 1 or Level 2 chargers.

According to the campaign document posted to the National Highway Traffic Safety Administration (NHTSA) website, first spotted by a member of the RivianForums, the issue affects both R1T and R1S with an approximate build between December 2022 and March 2023. These EVs were built with faulty components from a parts supplier and while AC charging is disabled, DC fast charging still works.

If your Rivian EV is part of the affected population, the company will replace the onboard charger for free.

With the uncertain build dates, and no mention of the number of EVs affected, it appears as though Rivian is unsure of the exact extent of the problem. Based on comments on the RivianForums, not a lot of owners have been impacted, but those that have said a workaround is to lower the amperage of the onboard charger from the max 48 amps to 40 or 32 amps.

We have reached out to Rivian to see if the issue also affects Canadian vehicles (no such notice has been posted by Transport Canada), and we will update this article when we get a response.
