This vehicle has experienced two separate failures of the high-voltage (HV) battery pack, each resulting in a different drive unit being damaged and total loss of electrical systems while driving. First incident (July 28, 2025): While driving, all warning lights illuminated and the vehicle indicated a possible electrical hazard. The vehicle lost power completely. It was taken to a Rivian service center on July 29, 2025, and was not returned until August 15, 2025 — a total of 17 days out of service. Rivian’s technicians found multiple faults in the HV battery pack and replaced it. Rivian’s own repair notes state that its engineering team requested the front drive unit also be replaced “due to the nature of the failure with the HV battery pack” — i.e., Rivian attributed the drive unit damage to the battery pack failure, not to an independent defect. Both the HV battery pack and front drive unit were replaced under warranty. Second incident (June 29, 2026, approx. 16,256 miles): After charging at a Tesla Supercharger, the vehicle displayed a “Rivian thermal system fault” warning, which indicated driving could continue. While subsequently driving on the highway, the vehicle displayed a “reduced performance” warning, followed by an “all-wheel drive system fault” warning. A loud popping sound was then heard from the rear drive unit, accompanied by visible and smell of smoke in the vehicle. The driver safely pulled over. All electrical systems malfunctioned in the same manner as the first incident. The vehicle is currently undergoing diagnosis; based on the symptoms (identical to the first incident) and Rivian’s own causal link between battery failure and drive unit damage in the first incident, it is possible the HV battery pack is again involved, this time in connection with the rear drive unit.

The contact owns a 2025 Rivian R1T. The contact stated that while driving approximately 50 MPH on a local road, the driver’s side charging port door detached from the vehicle. No warning light was illuminated. The vehicle was taken to a local service center but was not repaired. The manufacturer was notified of the failure. The failure mileage was 800.

AXM module failure, Driver+ and cameras disengaged during drive. No accidents occurred, driver quickly took control.

While scheduling service for NHTSA recall No. 25V-387/FSAM-1693 (Front Turn Signal Lamps malfunction that leads to no fulfillment of FMVSS 108 requirements) I was refused correction of the recall by the Rivian Miami Service Center rep (Service Advisor Joel). I was informed that Rivian has informed the Service Advisors that this recall will only be performed on already malfunctioning lamps or in cold weather areas (car is in Miami). However, none of this is defined in the recall notice sent, nor in the Rivian and NHTSA recall database. Requested written confirmation by Rivian of this directive to both the Service Advisor and Service Representative but neither had one. The advisor mentioned he had seen one in the past but does not recall where. Meanwhile, Rivian is refusing addressing the recall on my vehicle.

The half shaft axel on My Rivian R1T broke in under 6000K miles. Rivian tried hard to deny it, but did finally concede and fix it. But upon return there is still something wrong with the drive train.
