Rivian R1T / R1S battery warning (2022–2025)
Rivian R1T / R1S · 2022–2025 · all trims
Reported symptoms
12V (the vehicle's low-voltage accessory battery system) battery repeatedly discharges or the vehicle fails to wake/start
Vehicle reports low-voltage, electrical, accessory-power, or charging warnings
Rivian app reports vehicle offline, incorrect status, or failed wake behavior
Door locks, handles, lighting, infotainment, or accessory systems behave inconsistently before a low-voltage event
Vehicle becomes disabled after sitting parked, after charging, or after an OTA (Over-the-Air software update) update
Rivian service references 12V battery, gateway, body-control, sleep/wake behavior, or software diagnostics
Questions to ask
Pose these to the service advisor at intake. Request answers in writing or via email.
Has Rivian reviewed vehicle-side logs for the 12V or low-voltage events?
Were stored, pending, or historical low-voltage, gateway, body-control, charging, or sleep/wake faults found?
Was parasitic draw or module wake/sleep behavior evaluated?
Was the issue diagnosed as 12V battery failure, software behavior, module fault, charging-control issue, or undetermined?
What software version was installed before and after service?
Will the app service record identify the root-cause assessment and final remedy?
Documents to request
Each item should be received in writing before authorizing repair work.
Rivian app service ticket with technician notes
Diagnostic summary of low-voltage, gateway, body-control, charging, and sleep/wake fault review
Written confirmation of software version before and after service
Written confirmation of parasitic draw or wake/sleep testing if performed
Parts invoice showing any 12V battery, module, or related component replacement
Closed Rivian service record showing warranty classification
Pre-service evidence
Capture before drop-off. Once the vehicle leaves your possession, proving prior condition becomes significantly harder.
Screenshot Rivian app offline status, low-voltage errors, and failed wake behavior
Photograph cluster or center-screen warnings
Note parking duration, plug-in status, state of charge, temperature, and whether an OTA update occurred recently
Save service messages and appointment updates in the Rivian app
Record odometer reading at service drop-off and pickup
Retain towing, jump-start, or roadside-assistance records
Service advisor interaction
Operational notes specific to the conversation at the service desk.
Use the Rivian app thread as the official written record.
Ask Rivian to document whether the 12V failure is the root cause or a symptom of software/module behavior.
A generic '12V battery replaced' note is incomplete if repeated depletion or app offline behavior was reported.
If no active fault exists, request written confirmation that historical logs or codes were reviewed.
If the remedy is software-only, request before-and-after software versions.
Repair authorization
Cautions before signing.
Do not authorize paid low-voltage diagnostic or repair work until warranty classification is clarified in writing
If Rivian proposes customer-pay 12V replacement, request written explanation of why the root cause is not warranty-covered
Separate unrelated work from the low-voltage concern before approval
Review app estimates carefully before approving
Post-service verification
Complete before leaving the service location. Issues that surface after departure are operationally harder to attribute to the visit.
Confirm the vehicle wakes, starts, locks, unlocks, and reports app status normally
Confirm no low-voltage or electrical warnings remain after a full drive cycle
Confirm the service record identifies whether testing went beyond simple battery replacement
Monitor wake/start and app status during the first week after service
Save the closed service record
If recurrence happens, document parking duration and plug-in state before opening a new case

Service inquiry — Rivian repeated 12V / low-voltage concern
Rivian Service,
I am scheduling my [YEAR] Rivian [MODEL], VIN [VIN], for a repeated 12V or low-voltage concern.
Observed symptoms:
[DESCRIBE LOW-VOLTAGE WARNINGS, FAILED WAKE/START, APP OFFLINE BEHAVIOR, PARKING DURATION, PLUG-IN STATUS, AND DATES]
Please confirm in writing:
1. Whether vehicle-side logs were reviewed.
2. Whether stored, pending, or historical low-voltage/gateway/body-control/charging/sleep-wake faults were found.
3. Whether parasitic draw or module wake/sleep behavior was evaluated.
4. Whether the root cause is 12V battery failure, software behavior, module fault, charging-control issue, or undetermined.
5. Software version before and after service.
6. Warranty, campaign, goodwill, or customer-pay classification.
Please include these findings in the Rivian app service record.
Thank you.
Warranty notes
Rivian low-voltage, software, gateway, and body-control components should be evaluated under Rivian's applicable warranty terms for VIN (Vehicle Identification Number) [VIN].
Software-only remedies do not extend warranty unless Rivian states otherwise in writing.
Goodwill repairs do not extend the warranty period. Confirm classification in writing.
Repeated 12V depletion should be documented as recurring service history if symptoms return.
Observational patterns
Low-voltage complaints should document parking duration, state of charge, whether the vehicle was plugged in, and whether the issue followed an OTA update.
If only the 12V battery is replaced, request written confirmation that module wake/sleep behavior and parasitic draw were evaluated.
App offline status and failed wake/start events should be preserved because they help establish timing.
