Is Your 2023 Rivian R1T Experiencing Repeated 12-Volt Battery Failures?

A vehicle can have a massive high-voltage battery pack and still become completely unusable because of a comparatively small 12-volt battery.

That can be a frustrating reality for electric-vehicle owners.

The 2023 Rivian R1T relies on its low-voltage electrical system to power and initialize critical vehicle electronics. When that system fails, an owner may discover that the truck will not properly wake up, unlock, initialize its computer systems, or become driveable.

At least one publicly reported 2023 R1T complaint describes multiple 12-volt battery failures, including a first battery replacement under warranty followed by another failure. The owner reported that the truck could not be driven when the battery failed because the vehicle’s electronic systems could not start normally.

That is an individual consumer report. It does not establish that every 2023 R1T has a defective 12-volt system or that all battery failures share the same cause.

But when the same Rivian repeatedly becomes disabled because of low-voltage battery problems, the repair history may raise important questions under Wyoming’s Lemon Law, Rivian’s written warranty, and the federal Magnuson-Moss Warranty Act.

Why Does an Electric Truck Even Need a 12-Volt Battery?

It may seem counterintuitive.

The R1T has a large high-voltage traction battery designed to propel a heavy electric pickup for hundreds of miles.

Why should a small 12-volt battery matter?

Modern EVs generally use a separate low-voltage electrical system to support functions such as computers, control modules, locks, communications systems, and the electronics necessary to bring the rest of the vehicle online.

The high-voltage pack may contain plenty of energy, but the truck still depends on its low-voltage architecture to start the systems that allow the vehicle to operate.

That means a low-voltage failure can potentially leave an R1T effectively immobilized even when the main battery has a substantial state of charge.

Rivian itself has warned owners of certain R1T and R1S vehicles in service communications that a 12-volt failure could leave a customer unable to access or drive the vehicle and could require a tow.

That particular communication should not be assumed to apply to every 2023 R1T. Applicability depends on the vehicle and the underlying service action.

But it illustrates the practical consequence of a failed low-voltage system in a Rivian.

What Can a Rivian 12V Failure Look Like?

Owners may describe the issue in different ways:

• The truck will not wake up.
• The vehicle will not unlock normally.
• A 12V battery warning appears.
• The R1T becomes completely unresponsive.
• The truck cannot be placed into Drive.
• The vehicle requires a jump or service intervention.
• The truck must be towed.
• The 12V battery is replaced, but another battery later fails.
• The problem appears after the vehicle has been parked.
• Rivian replaces the battery but cannot explain why it failed.

Those symptoms do not necessarily have one cause.

A low-voltage problem could potentially involve the battery itself, charging circuitry, software, electrical loads, wiring, battery management, or another component.

Consumers should avoid trying to diagnose the issue themselves.

For warranty purposes, it is often more important to document what occurred, what Rivian diagnosed, what Rivian repaired, and whether the same condition returned.

One Dead Battery Is Different From Repeated Battery Failure

A single battery replacement does not automatically make an R1T a lemon.

Automotive batteries can fail.

The more significant question is what happens after Rivian replaces the battery.

Consider these two situations.

In the first, an R1T experiences one 12V failure, Rivian replaces a defective battery under warranty, and the problem never returns.

In the second:

Visit 1: R1T is completely unresponsive. Rivian replaces the 12V battery.

Visit 2: The truck becomes undriveable again several months later. Another battery is installed.

Visit 3: A low-voltage warning returns. Rivian performs diagnostic work.

Visit 4: The truck again requires towing because the low-voltage system will not initialize the vehicle.

Those histories are very different.

Repeated battery replacement without identifying why the batteries keep failing may warrant closer scrutiny.

Make Sure the Rivian Repair Records Describe the Actual Problem

The wording of a service record can matter.

A vague description such as:

“Battery issue”

does not tell the whole story.

A more useful description might be:

“Customer states vehicle became completely unresponsive and could not be placed into Drive despite high-voltage battery showing charge. 12V battery warning appeared before vehicle became inoperable.”

Only report what actually occurred.

Also make sure the paperwork indicates whether:

• The truck required towing;
• Mobile service responded;
• The 12V battery was replaced;
• Diagnostic trouble codes were stored;
• Software was updated;
• The vehicle remained at a service center; or
• The condition had occurred previously.

Rivian Has Addressed 12V Battery Issues on Other R1 Vehicles

Rivian has issued service actions concerning 12-volt battery problems on certain later R1T and R1S vehicles.

For example, a 2025 customer-satisfaction campaign addressed certain model-year 2025 R1T and R1S vehicles whose 12V battery brackets could potentially damage the battery. Rivian’s campaign stated that an affected vehicle might display a 12V warning or become unable to power up or drive, and the repair included replacing the battery and associated brackets.

That campaign concerns 2025 vehicles, not the 2023 R1T discussed in this article.

It should therefore not be represented as evidence that a 2023 R1T has the same problem.

However, it provides useful context: Rivian recognizes that low-voltage battery conditions can render an R1 vehicle inoperable.

For a 2023 owner, the diagnosis must still come from the actual vehicle’s service records.

Wyoming Has Its Own Lemon Law

Wyoming’s Lemon Law is contained primarily in Wyo. Stat. § 40-17-101. The Wyoming Attorney General identifies that statute as the state’s Lemon Law.

The statute applies to qualifying motor vehicles under 10,000 pounds unladen weight that are sold or registered in Wyoming. It protects certain purchasers and other consumers entitled to enforce the manufacturer’s express warranty.

For a qualifying new vehicle, the consumer must report the warranty nonconformity to the manufacturer, its agent, or an authorized dealer within one year after original delivery. If it is timely reported, the statute requires the necessary warranty repair even if the repair itself occurs after that one-year period.

That first-year requirement makes the earliest repair records especially important.

Wyoming Requires a Substantial Impairment

Not every defect entitles a consumer to a refund or replacement.

Wyoming law focuses on a defect or condition that substantially impairs both the use and fair market value of the vehicle to the consumer and that the manufacturer cannot correct after a reasonable number of attempts.

A recurring 12V failure could potentially be significant because it may leave the R1T completely unusable.

But the legal standard still has to be established based on the facts.

A momentary warning that is permanently corrected may not have the same significance as a truck that repeatedly:

• Will not power up;
• Cannot be driven;
• Requires towing;
• Leaves the owner stranded;
• Needs repeated low-voltage battery replacement; or
• Remains unavailable for extended repairs.

Wyoming’s Repair-Attempt Presumption Is More Than Three Attempts

The wording of Wyoming’s statute is important.

The state presumes that a manufacturer received a reasonable number of repair attempts when the same nonconformity has been subject to repair more than three times within one year following original delivery and continues to exist.

“More than three” means the statutory presumption is tied to at least four repair attempts.

This is worth stating accurately because online summaries sometimes describe Wyoming as simply having a “three repair” Lemon Law.

The statutory language is more precise.

Consider this hypothetical:

Repair 1 — 2,300 miles: R1T will not power up. Low-voltage battery replaced.

Repair 2 — 4,100 miles: 12V warning returns. Rivian performs diagnostic work.

Repair 3 — 5,600 miles: Truck again becomes undriveable and requires mobile service.

Repair 4 — 7,000 miles: Same low-voltage condition returns.

If the nonconformity continues, that history could potentially implicate Wyoming’s statutory presumption, assuming the other requirements are satisfied.

Wyoming Also Has a 30-Business-Day Rule

Repeated repairs are not the only way to establish the statutory presumption.

Wyoming law also provides a presumption when the vehicle has been out of service because of repair for a cumulative total of 30 business days within the applicable one-year period.

The statute says business days, which is an important distinction from states that use calendar days.

Imagine an R1T that spends:

8 business days awaiting diagnostic work;

7 business days waiting for a battery or component;

9 business days during a later electrical repair; and

7 additional business days after the condition returns.

That totals 31 business days.

The vehicle does not necessarily need to be at the service center for all 30 days during one visit.

Keep records showing precisely when the truck became unavailable and when it was returned.

Rivian’s Mobile-Service Model Makes Documentation Especially Important

Rivian’s service model can differ from that of a traditional manufacturer.

Some work may occur through mobile service.

Other repairs may require transport to a Rivian service center.

That can make documentation especially important.

For every incident, preserve:

• Mobile-service records;
• Service-center invoices;
• Tow records;
• Roadside-assistance records;
• App messages;
• Rivian support chats;
• Emails;
• Repair estimates;
• Battery replacement paperwork; and
• Dates when the truck could not be used.

Do not assume an interaction is irrelevant simply because a technician came to your home rather than the truck going to a conventional dealership.

Wyoming Requires Direct Written Notice Before the Presumption Applies

Wyoming has another significant procedural requirement.

The statutory repair presumptions generally do not apply against the manufacturer unless the manufacturer has received prior direct written notification from or on behalf of the consumer and has had a reasonable opportunity to cure the alleged defect.

This means app chats and service appointments should not automatically be assumed to satisfy the direct-written-notification requirement.

If a repeated defect is becoming a potential Wyoming Lemon Law matter, written notice directly to Rivian can be important.

Preserve:

• A copy of the notice;
• Date sent;
• Delivery confirmation;
• Rivian’s response; and
• The repair opportunity Rivian provides afterward.

What Should Written Notice to Rivian Include?

A notice should be factual and specific.

For example:

My 2023 Rivian R1T has repeatedly experienced failure of the 12-volt electrical system, causing the vehicle to become unable to power up or drive. The vehicle has been presented for repair on multiple occasions, including replacement of the 12-volt battery, but the condition continues.

It can also identify:

• VIN;
• Original delivery date;
• Current mileage;
• Dates of previous repairs;
• Number of 12V replacements;
• Tow incidents; and
• Number of days the vehicle was out of service.

Do not exaggerate the history.

Precise documentation is more useful than dramatic language.

What Remedies Can Wyoming Lemon Law Provide?

If Rivian cannot bring a qualifying vehicle into conformity with its express warranty after a reasonable number of attempts, Wyoming law requires the manufacturer to provide one of two principal remedies.

The manufacturer must either:

Replace the vehicle with a new or comparable vehicle of the same type and similarly equipped, or

Accept return of the vehicle and refund the full purchase price and collateral charges, less a reasonable allowance for the consumer’s use.

The reasonable-use deduction is generally tied to use before the consumer first reported the nonconformity and certain subsequent use while the vehicle was not out of service for repair.

Wyoming Lemon Law Also Allows Attorney’s Fees

Wyoming’s statute provides another important consumer protection.

A consumer injured by a violation may bring a civil action to enforce the Lemon Law and may recover reasonable attorney’s fees from the manufacturer that issued the express warranty.

Fee-shifting can be significant because warranty litigation can otherwise become expensive relative to the amount an individual consumer could reasonably spend pursuing a manufacturer.

Rivian’s Informal Dispute Procedure May Matter

Wyoming’s law also provides that the statutory refund-or-replacement remedy may not apply where a consumer fails to exhaust a manufacturer’s qualifying informal dispute-settlement procedure, if one exists and complies with applicable federal requirements.

Consumers should therefore review Rivian’s warranty materials to determine whether a qualifying dispute procedure applies to their particular claim.

Do not assume that simply opening a Rivian support ticket is the same as completing a legally required dispute-settlement process.

Abuse, Neglect, and Unauthorized Modifications Can Affect a Claim

Wyoming also gives manufacturers specific defenses.

The statute permits a manufacturer to argue that:

• The alleged condition does not substantially impair the vehicle’s use and fair market value; or
• The problem resulted from abuse, neglect, or an unauthorized modification or alteration by the consumer.

That can matter with an electric truck that owners sometimes modify with aftermarket electrical accessories.

If Rivian claims an aftermarket device caused the 12V problem, ask that conclusion and its technical basis be documented.

The mere existence of an aftermarket component does not by itself establish causation, but the specific facts matter.

What If Rivian Replaces the 12V Battery More Than Once?

This can become one of the central questions in the case.

Replacing a dead battery may correct the immediate symptom.

It does not necessarily identify why the battery failed.

Suppose Rivian replaces the first battery.

Six months later the second battery fails.

Rivian installs another.

Three months afterward, the low-voltage warning returns again.

At that point, questions may include:

Is the battery itself the problem?

Is something failing to maintain its charge?

Is an electrical load draining it?

Is a software or control-system condition involved?

Has Rivian actually repaired the underlying nonconformity?

A Lemon Law case does not require the owner to personally answer those engineering questions.

It does require a clear repair history.

What If the Truck Becomes Completely Inaccessible?

Low-voltage failures can be particularly inconvenient in an EV because so many ordinary vehicle functions depend on electronics.

If your R1T:

• Cannot unlock normally;
• Cannot initialize;
• Cannot enter Drive;
• Requires emergency access;
• Has to be transported rather than driven; or
• Requires roadside intervention,

make sure those consequences are documented.

Rivian has acknowledged in service communications concerning certain R1 vehicles that a 12V failure can leave a vehicle unable to be accessed or driven and may necessitate towing.

Again, the specific service communication must not be assumed to apply to every 2023 truck, but the operational consequence is important.

What If Rivian Says the Battery Is a Wear Item?

Ask Rivian to identify the applicable warranty provision.

A 12-volt battery may be subject to specific warranty terms or limitations.

Do not rely solely on a verbal statement from a service representative.

Request documentation showing:

• Why coverage was denied;
• Which warranty provision applies;
• Whether Rivian believes the failure resulted from normal wear;
• Whether a diagnostic test was performed; and
• Whether a separate component caused the battery failure.

This becomes particularly important after repeated failures.

What If Your 2023 R1T Is Now Outside Wyoming’s One-Year Lemon Law Period?

For many 2023 vehicles, this is now the most important issue.

Wyoming requires the nonconformity to be reported within one year following original delivery for its statutory new-vehicle repair obligation.

That means a brand-new Wyoming Lemon Law claim based on a problem first appearing in 2026 would present a very different situation from a 12V problem first reported during the truck’s first year.

But do not look only at the truck’s age today.

Ask:

When was the first low-voltage problem reported?

A 2023 R1T may now be three years old, but perhaps its first battery failed just six months after delivery.

Those original records could still be very important.

Wyoming’s Statute Does Not Eliminate Other Remedies

Wyoming’s Lemon Law expressly says that it does not limit a consumer’s rights or remedies under other statutes.

That matters considerably for older R1Ts.

Even when the state Lemon Law does not provide relief, other warranty theories may deserve consideration.

These may include:

• Breach of Rivian’s written warranty;
• Applicable implied warranties;
• The federal Magnuson-Moss Warranty Act; and
• Other available consumer-law remedies depending on the circumstances.

Breach of Rivian’s Written Warranty

The central breach-of-warranty question is often straightforward:

Did Rivian provide the repair performance promised in its written warranty?

Relevant facts might include:

• When the first 12V failure occurred;
• Whether Rivian replaced the battery under warranty;
• How many additional failures occurred;
• Whether the truck was still covered;
• Whether Rivian diagnosed an underlying cause;
• Whether service was mobile or at a service center;
• Whether Rivian later denied coverage; and
• Whether the same condition continued after repair.

A vehicle can potentially fall outside the technical requirements of a state Lemon Law while still presenting a warranty dispute.

The Magnuson-Moss Warranty Act

The federal Magnuson-Moss Warranty Act can also provide remedies for qualifying breaches of written and implied warranties.

Magnuson-Moss is not a nationwide Lemon Law with a fixed number of required repairs.

Instead, it generally operates together with the manufacturer’s warranty and applicable state warranty law.

One important feature is that a successful consumer may potentially recover reasonable attorneys’ fees and costs in a qualifying case.

That can make enforcement of warranty rights more practical for consumers facing repeated expensive or unsuccessful repairs.

Keep Screenshots From the Rivian App

With a connected vehicle like an R1T, not all useful evidence arrives on paper.

Preserve screenshots showing:

• 12V warnings;
• Vehicle-unavailable messages;
• Service requests;
• Roadside-assistance communications;
• Tow arrangements;
• Appointment dates;
• Rivian support responses; and
• Confirmation that repairs were completed.

Electronic communications can help reconstruct the chronology if paper invoices are incomplete.

Build a 12V Failure Timeline

For example:

May 8, 2023 — 2,100 miles: 12V warning appears.

May 10 — 2,130 miles: Vehicle becomes unresponsive and is towed.

May 15 — 2,130 miles: Rivian replaces 12V battery.

September 22 — 6,800 miles: Low-voltage warning returns.

September 24 — 6,820 miles: Mobile service performs diagnostic work.

November 17 — 8,500 miles: Vehicle again will not power up.

November 20 — 8,500 miles: Second battery replacement.

January 2024 — 10,100 miles: Same condition returns.

A timeline like this makes the pattern immediately apparent.

Could Your 2023 Rivian R1T Qualify Under Wyoming Lemon Law?

Important questions include:

Is the vehicle within Wyoming’s statutory definition of a covered motor vehicle? Wyoming generally covers qualifying vehicles under 10,000 pounds unladen weight that are sold or registered in the state.

Was the nonconformity reported within one year following original delivery?

Does the defect substantially impair both the use and fair market value of the R1T?

Has the same nonconformity been subject to repair more than three times and continued to exist?

Was the R1T out of service for 30 or more business days?

Did Rivian receive prior direct written notice and a reasonable opportunity to cure?

Does Rivian have a qualifying informal dispute-settlement procedure that must first be exhausted?

And if Wyoming Lemon Law does not apply:

Did Rivian nevertheless breach an applicable written or implied warranty?

Contact Ginsburg Law Group About Rivian R1T 12V Battery Problems

If your 2023 Rivian R1T has experienced repeated 12-volt battery failures, become unresponsive, required towing, or needed multiple battery replacements, preserve your complete service history.

At least one publicly reported 2023 R1T complaint describes repeated 12V battery failure and a vehicle that becomes undriveable when the low-voltage system fails. That report does not establish a defect in every R1T, but repeated failures in an individual vehicle can warrant closer examination.

Wyoming’s Lemon Law is unusually concise, but its requirements are specific: the condition generally needs to be reported within the first year, substantially impair use and fair market value, and remain unresolved after the statutory repair opportunities. Direct written notice to the manufacturer can also be critical.

Ginsburg Law Group represents consumers in Lemon Law and breach-of-warranty matters. Keep every Rivian service record, mobile-service invoice, app communication, tow record, warranty document, and battery replacement record.

Those documents can help establish when the defect began, how often Rivian attempted to repair it, how long the truck was unavailable, and whether Wyoming Lemon Law, breach-of-warranty law, or the Magnuson-Moss Warranty Act may provide a remedy.

This article is for general informational purposes only and does not constitute legal advice. Wyoming Lemon Law and warranty claims are fact-specific and depend upon the vehicle, transaction, warranty terms, repair history, notice, timing, and other circumstances.
