Rivian is dropping a Ghostbusters-themed over-the-air update tomorrow, October 9, turning every R1T, R1S, and R2 in the field into a rolling tribute to the 1984 franchise. The company also built six physical R1S “Ecto-R1” customs modeled after the famous Ecto-1 Cadillac, because apparently software alone wasn’t enough.
This is the third year Rivian has shipped a Halloween “car costume” to its customers. Knight Rider and Back to the Future came first. The Ghostbusters tie-in pushes the formula further with more licensed content, more interactive features, and a full-blown in-car game.
Install version 2026.36.0 on an R1 or 2026.36.40 on an R2 and the infotainment screen asks if you want to “hunt some ghosts.” Accept, and a 1980s-style Ecto-1 control panel takes over the display. A big red switch powers the whole thing up and blasts Ray Parker Jr.’s theme song through the speakers.
From there, the rabbit hole gets deep. Eight movie sound effects, four interior and exterior light shows, an Ecto-1 siren that plays both inside and out, a themed game, and a Trick or Treat mode that Rivian says is more elaborate than previous versions. Easter egg hints are scattered throughout the interface.
The entire color scheme across the infotainment and instrument cluster flips to Slimer green on black. Navigation goes green. The drive mode screen replaces pastoral nature scenes with the Ecto-R1 parked in front of 550 Central Park West, dimensional gate looming overhead.
Open the 360-degree camera and Slimer is flying around your car. Rivian’s Yeti mascot becomes a ghost. Pedestrians on the Autonomy screen become zombies and interior ambient lighting turns green.
Gen 2 R1s and R2s get more exterior sound options than Gen 1 vehicles. Owners can swap their lock sound for the Ecto-1 siren, a proton pack firing, or the “Ghostbusters!” yell from the chorus. Gen 1 models are limited to just the siren.
All of it vanishes November 2. Licensing agreements dictate the expiration date, same as in previous years. Rivian has never been able to keep these themed updates permanently installed, which creates artificial scarcity and a ticking clock that drives engagement.
No other automaker is doing this at this scale. Tesla has its light show feature, and Dodge put demonic Easter eggs in the old Challenger. But nobody else is shipping fully licensed, franchise-integrated software experiences to an entire fleet and then yanking them back a few weeks later.
The six physical Ecto-R1 builds are a different matter entirely. Rivian showed them off at a press preview but hasn’t said whether they’ll appear at public events or anywhere owners might actually see them. They exist mostly as content generators, visual proof that the brand takes its pop culture partnerships seriously.
Rivian keeps doubling down on this strategy because it costs relatively little compared to traditional marketing and generates outsized social media attention. The software is temporary. The brand impression is not.
Whether this kind of thing sells trucks is a question Rivian still has to answer with quarterly delivery numbers. But three years in, the Halloween OTA update has become the company’s most reliable cultural moment, a tradition built on code that self-destructs. The Ghostbusters licensing window closes in 25 days.
