A driver on I-15 southbound near Primm sees the Rivian Highway Assist icon on the cluster and assumes the system covers roadside rescue. It doesn’t. Highway Assist is a hands-on driver-aid feature. It steers, brakes, and accelerates within a lane. It does not charge the car, jump the 12V, or arrange a tow. A Rivian that runs out of charge on a valley freeway still needs a local operator quote.
What Rivian Highway Assist actually is
Rivian Highway Assist is a Level 2 driver-aid feature available on the R1T and R1S with the Driver+ package. It uses the camera array, radar, and the car’s mapping to:
- Keep the vehicle centered in its lane on a mapped highway
- Match speed with the car ahead
- Slow and stop in traffic
- Resume from a stop in traffic
- Suggest lane changes when the turn signal is engaged
Highway Assist is not autonomous driving. The driver’s hands must stay on the wheel. The driver’s eyes must stay on the road. The system disengages if the driver doesn’t respond to warnings. The system is also limited to mapped highways, which in the Las Vegas Valley means I-15, US-95, I-11, and parts of the 215 beltway.
Highway Assist does not cover:
- Towing
- Battery jump start
- Mobile charging
- Tire changes
- Lockout assistance
- Accident response
A Rivian that runs out of charge while Highway Assist is engaged will still need a tow or a mobile charge. Highway Assist doesn’t help once the pack is flat. The system shuts down at low state of charge to preserve range for the safety systems.
What the Rivian roadside program covers
Rivian roadside assistance is a separate service, included with the new-vehicle warranty and the Rivian membership. It is administered through a third-party dispatch network. The program covers towing, battery jump start, flat-tire change, lockout assistance, and winching for off-road recovery in approved locations.
The Rivian program does not include a mobile Level 2 charge to a flat traction pack. It does not include a CCS adapter for non-Rivian EVs. It covers towing and basic 12V help, not energy delivery.
The Rivian app also includes Rivian Adventure, which covers off-road recovery for Rivian-owned trails. A Rivian stuck on a designated trail in the desert can call Adventure for a winch-out. Adventure does not cover a flat pack on a freeway shoulder.
Where the Rivian program falls short in the valley
The Las Vegas Valley is large, and Rivian’s contracted tow network is concentrated in the metro core. A driver in Summerlin, Henderson, or the Strip corridor will usually see a contracted tow within an hour. A driver in Primm, Jean, Boulder City, or Mesquite will see a much longer wait.
The official NWS Las Vegas record shows an average July high of 104.5F, with about 78 days a year at or above 100F. Sitting in that heat for two to four hours is a real safety problem for kids, pets, or older passengers.
A second gap is energy delivery. A Rivian can sit on a flat pack with the 12V still alive. Highway Assist is unavailable because the pack is below the threshold. The Rivian program covers a tow to a service center, not energy delivered to the parking stall.
When to skip the Rivian app and call a local operator
A local independent operator typically quotes the work and bills the driver directly. The operator carries portable Level 2 EVSEs with CCS1 and J1772 adapters, lithium-compatible smart boosters for the 12V, and a flatbed tow rated for EVs.
The cases where a local operator is faster than the Rivian program include a flat traction pack on a freeway shoulder, a dead 12V in a parking lot, a charge port stuck on a Rivian, and out-of-coverage stalls in Boulder City or Primm where the Rivian wait is long.
Mobile EV charging covers the energy delivery. Out of charge recovery is the umbrella for a flat traction pack. Rivian charge port stuck in valley heat walks through the cable-release workflow.
What Highway Assist can and can’t do for a stalled Rivian
Highway Assist does not work once the Rivian is parked. The system only operates while driving. A stalled Rivian sees the Highway Assist icon go gray and disappear from the cluster.
The Rivian’s other driver-aid features are also unavailable once the pack is flat. The camera array, the radar, and the lane-keeping system all need the traction pack’s 12V bus.
A driver who sees a Highway Assist icon on the cluster should not assume the system will rescue them. The icon is a driver-aid indicator, not a service contract.
How the Rivian program and a local operator work together
The Rivian app can be the right call when the Rivian is under warranty and the driver wants a service-center visit. The local operator is the right call when the driver needs to get the car moving now.
A typical workflow: the driver calls Rivian through the app and gets a dispatch window. The driver also calls (702) 935-4699 and gets a local operator quote. If the local operator is faster, the driver takes the local session and cancels the Rivian tow. The Rivian program may reimburse a non-Rivian tow in some cases. The owner should ask the Rivian service advisor before paying out of pocket.
What the Rivian app doesn’t show
The Rivian app shows the state of charge and lets the driver precondition the cabin. It does not show the health of the 12V auxiliary battery. It does not show the operator queue or the dispatch ETA. It does not show whether a nearby CCS fast charger is in service.
Drivers who depend on the app for charging visibility should also use a third-party charging app for stall status. ChargePoint, EVgo, and Electrify America all publish stall status in their apps. PlugShare shows driver reports of failed stalls. The driver who knows the local stall is broken before pulling in saves the day’s range.
For Rivian coverage across the valley, Rivian R1T R1S 12V in valley heat covers the related 12V failure mode. Rivian charge port stuck in valley heat walks through the cable-release workflow. The Rivian Support page on Driver+ covers what Highway Assist actually does. NDOT’s Freeway Service Patrol page describes what the patrol does and does not do on valley freeways.
Call (702) 935-4699 when the Rivian needs help now. Charge Pro LV connects drivers with operators who carry CCS1 and J1772 adapters, lithium-compatible smart boosters, and portable Level 2 sources. The operator quotes the work before it starts.

How long does the Rivian contracted tow take in the valley?

Will Rivian reimburse a non-Rivian tow?
In some cases. The details depend on the warranty terms and the failure type. Ask the Rivian service advisor before booking a non-Rivian tow and before paying out of pocket.
