EV manufacturer Rivian is facing a software glitch that has left some owners of second-generation R1T and R1S vehicles unable to charge at full speed on Level 2 home chargers.
Customer complaints on social media over the past several days indicate the issue caps charging at 8 amps following last week’s rollout of the 2025.46 over-the-air update — one of the company’s most significant releases this year.
Prior Charging Issues
Besides major updates on autonomy, new features and the digital key integration, the update was also intended to address an AC charging problem Rivian had identified earlier this month.
As reported by EV, the company emailed customers warning that the issue “prevents certain R1 vehicles from AC charging at home or with Level 2 chargers when in colder weather.” DC fast charging was not affected.
The notification came nearly a month after a separate battery display issue affected several vehicle owners.
New Bug Emerges
The 2025.46 update appears to have introduced a new problem while attempting to fix the cold-weather failures.
The bug drastically reduces power intake to approximately 1.9 kW on a 240V circuit.
Multiple owners reported that their vehicles automatically reverted to an 8-amp charging limit on Level 2 setups after installing the update, regardless of attempts to adjust settings.
The limitation represents a significant downgrade from typical rates of 32 amps or higher, extending charging times from hours to days for a full battery.
The issue appears isolated to certain Gen 2 models, with Gen 1 vehicles largely unaffected based on user feedback.
Owner Reports and Impact
Discussions on Reddit’s r/Rivian community reveal a pattern of complaints starting within days of the update’s installation.
One Gen 2 R1S owner reported their charging rate dropped from 48 amps to 24 amps on a Tesla home charger immediately after updating. Another described the system persistently resetting to 8 amps, rendering overnight charges ineffective.
The glitch has been particularly disruptive for owners relying on home Level 2 charging, forcing some to seek alternatives such as public DC fast chargers, which remain unaffected.
Rivian’s Acknowledgment and Response
Rivian has acknowledged the issue through customer service interactions and forum engagements, confirming the company is aware of the AC charging limitations and actively developing a software patch.
As of Tuesday, no official timeline for the fix has been publicly announced. Service tickets remain open for affected owners, with roadside assistance providing limited immediate support.
New Features in Update
The 2025.46 update also delivered several new features alongside the charging fixes.
The release includes a Customizable Driver Display and the Kick Turn feature for second-generation Quad vehicles, which Rivian first teased in July.
Digital key support for Apple and Android devices is also rolling out to Gen 2 vehicles after being delayed in September.
Temporary Workarounds
Users have shared makeshift solutions with varying success.
A common recommendation involves performing a hard reset by holding both steering wheel scroll wheels until the vehicle reboots, which has temporarily restored normal charging rates for some owners.
Soft resets and manual charger adjustments have also been attempted, though the system often reverts to the lower limit.
Consumer Reports Ranking
The charging issues come despite Rivian ranking first for the third consecutive year in Consumer Reports’ Owner Satisfaction ratings, which evaluates vehicles based on performance, comfort, and usability.
Consumer Reports surveys “tens of thousands” of vehicle owners annually through its Annual Auto Surveys, which covered approximately 380,000 vehicles in 2025.
However, despite its high satisfaction score, consumers rated Rivian as the least reliable brand in 2025.
