It’s an unsettling moment for any EV owner, especially when you drive a premium adventure vehicle like a Rivian R1T or R1S. You press the brake, the accelerator, or just try to wake it up, and nothing happens. Your Rivian won’t start, the screens are blank, or it just feels completely unresponsive. Before you panic and call a tow truck, there are some common issues and troubleshooting steps you can try right here in San Diego.

Common reasons a Rivian becomes unresponsive

Rivian vehicles, like all advanced EVs, are sophisticated machines. They rely heavily on complex software and multiple battery systems to operate. When your R1T or R1S seems unresponsive, it usually points to one of a few common culprits. The most frequent issues aren’t always what you’d expect. Often, it’s not a catastrophic failure of the main high-voltage battery. Instead, minor glitches in the vehicle’s computer systems or a depleted 12V auxiliary battery are usually to blame.

Software can sometimes freeze or encounter a bug, leading to blank screens or unresponsive controls. Think of it like a computer needing a reboot. Another common reason is a depleted 12V battery. While your Rivian’s large battery powers the motor, the smaller 12V battery powers all the vehicle’s low-voltage electronics. This includes the infotainment system, door locks, headlights, and the crucial relays that allow the main battery to engage. If the 12V battery is dead, your Rivian becomes a very expensive paperweight, even if the main battery is full. Key fob or phone key communication issues can also prevent the vehicle from waking up, making it seem like the Rivian won’t start at all. We’ll walk you through how to address these scenarios methodically.

How to perform a soft and hard reset

Many “won’t start” issues with a Rivian R1T or R1S can be resolved with a simple reset, similar to restarting your phone or computer. There are two main types of resets you can perform: a soft reset of the infotainment system and a hard reset of the entire vehicle. Starting with the soft reset is always a good idea, as it’s less intrusive and often fixes minor software glitches.

Performing a soft reset (infotainment system)

A soft reset focuses on the center display and typically resolves issues like unresponsive screens, app freezes, or minor system lags. To perform a soft reset:

  1. Locate the two scroll wheels on your steering wheel.
  2. Press and hold the left scroll wheel and the right scroll wheel simultaneously.
  3. Continue holding for about 15-20 seconds until the center display goes black.
  4. Release the buttons. The Rivian logo should reappear, and the system will boot back up.

Performing a hard reset (full vehicle system)

If a soft reset doesn’t work, or if your Rivian is completely unresponsive with no lights or sounds, you might need a hard reset. This reboots the vehicle’s entire computer system. To perform a hard reset:

  1. Locate the hazard light button (usually near the gear tunnel) and the right scroll wheel on the steering wheel.
  2. Press and hold both the hazard light button and the right scroll wheel simultaneously.
  3. Keep holding them down for at least 20-30 seconds. The screens will go black, and you might hear some clicking noises or see other lights briefly flicker.
  4. Once the screens are completely dark and the vehicle seems dormant, release the buttons.
  5. Wait a few moments. The Rivian logo should reappear on the center display, and the system will begin its full boot-up sequence. This can take a minute or two.

These resets are safe and can often bring your Rivian back to life. If your vehicle still won’t start after trying both resets, it’s time to investigate further, particularly the 12V battery.

Locating and checking the 12V battery status

Even though your Rivian is an EV, it still relies on a traditional 12V battery. This often-overlooked component is crucial for powering all the vehicle’s auxiliary systems: the main computer, door locks, lights, infotainment, and the contactors that connect the high-voltage battery to the motor. If this 12V battery dies, your Rivian becomes unresponsive, regardless of the charge level of your main propulsion battery. Symptoms of a failing 12V battery include a completely black infotainment screen, unresponsive key fobs, dim lights, or strange error messages.

The 12V battery in your Rivian R1T or R1S is located under the frunk. To access it, you’ll need to:

  1. Open the frunk. This might require using the manual frunk release if the electronic one isn’t working due to the dead 12V. Consult your owner’s manual for its exact location and procedure.
  2. Once the frunk is open, you’ll typically find a plastic cover that needs to be removed to expose the battery.
  3. Visually inspect the battery terminals for corrosion or loose connections. While a visual check won’t tell you the battery’s charge, obvious damage can be a clue.
  4. If you have a multimeter and know how to use it, you can check the voltage. A healthy 12V battery should read around 12.6V when fully charged. Anything significantly below 12V indicates a problem.
  5. Do not attempt to jump-start the 12V battery yourself unless you are familiar with the correct procedure and safety precautions outlined in your Rivian owner’s manual. Incorrect jump-starting can damage sensitive EV electronics. If you suspect a dead 12V battery in San Diego, calling a specialized EV roadside rescue service like Charge Pro SD is your safest bet. We offer expert non-Tesla EV rescue services, including safe 12V battery jump-starts and replacements for Rivians.

What to do if your key fob or phone key isn’t working

Modern vehicles like the Rivian R1T and R1S rely heavily on electronic communication between the vehicle and your key. If your Rivian won’t start, and you’ve ruled out software glitches and the 12V battery, the next logical step is to check your key fob or phone key. A communication breakdown here can prevent the vehicle from waking up or registering your presence, making it seem like the car is completely dead.

Key fob troubleshooting

First, consider the key fob’s battery. If the fob battery is low or dead, it won’t transmit a strong enough signal. Most Rivian key fobs use standard coin-cell batteries (e.g., CR2032) that are easy to replace. Check your owner’s manual for specific instructions on how to open the fob and swap the battery. Even with a dead key fob battery, Rivians usually have a passive entry method. You might need to hold the key fob directly against a specific NFC (Near Field Communication) spot on the vehicle, often on the door pillar or in the center console. This allows the vehicle to read the fob’s embedded chip even without battery power. Try this if your fob seems unresponsive.

Phone key troubleshooting

If you primarily use your phone as a key, check a few things:

  1. Bluetooth: Ensure your phone’s Bluetooth is enabled and working correctly. The Rivian app relies on Bluetooth to communicate with the vehicle.
  2. Rivian App: Open the Rivian app. Is it updated to the latest version? Sometimes, a pending app update can cause issues. Force close the app and restart it, or even try reinstalling it. Check its permissions to ensure it has access to Bluetooth and location services.
  3. Phone Battery: Make sure your phone isn’t dead. A low phone battery can sometimes cause connectivity issues.
  4. Signal Interference: In dense urban areas of San Diego, or near strong radio signals, interference can sometimes temporarily disrupt key communication. Try moving the vehicle or yourself to a different spot if possible.

Always keep your physical key card handy as a backup. This card uses NFC technology and usually works by tapping it against a designated spot on the door pillar, allowing you to unlock and start the vehicle even if both your key fob and phone key fail.
