This Problem Across All Years
Vehicle was flagged for software update 2025.34.01. Upon installation, the software produced an error. In response to initial support request, OEM pushed an unreleased and unpublished software update versioned 2025.34.20. The new update also produced the same errors, and additionally prevented the vehicle from being able to be shifted into the Drive position, rendering the vehicle immobile and unusable for a defined period of time.

Vehicle lurched to a stop in a parking lot, unable to shift into gear. Warnings: “motor fault detected”, “system fault detected”, “all wheel drive permanently engaged”, “replace 12v battery. “ Currently being repaired under manufacture warranty. Manufacturer confirmed drive unit needed to be replaced. This could have been a terrible accident if it happened on the freeway. My wife and dog were in the car with me. There were no warning signs leading up to this moment. We were stranded 400 miles from home and needed several tows to get home and to the service center.

Truck without warning, suddenly stopped and I was on one of the busiest streets in Los Angeles at an intersection, blocking a large amount of traffic and too dangerous to get out due to cars rapidly passing. Called Rivian support and they said it would take. two hours to get a tow truck to me even though AAA was only 20 min away, they would not call AAA. I was at risk of being rear ended. Fire department came and was able to move car to side of road. Rivian gave no assistance. Engine light came on and said call tow truck and do not drive, red lights, manual said it was dangerous.

The Driver+ (D+) feature on the Rivians have both adaptive cruise control and lane centering active at the same time. There is a function unknown to me that controls whether or not the D+ feature can turn on or remain on. In certain situations, the D+ features asks the driver the disable the system by pushing the right stalk upward with a red message on the gauge console screen. In other situations, the D+ feature forcibly disables with a similar red message on the gauge console screen. The messages themselves look very similar at first glance and require the driver to look down to discern between the two because the outcome for both scenarios is very different, particularly when D+ forcibly disables itself. When D+ disables itself (again the reasons are unknown to me at the time and not predictable other than maybe GPS location), there is a VERY brief warning to the driver then turns off and automatically brakes the vehicle. This D+ error is not as common as the other warning described above that asks the user to push the right stalk upward to turn it off. Once D+ forcibly turns itself off, the vehicle brakes aggressively. Due to muscle memory of the other similar-appearing error, it is normal to push the right stalk upward to disable it. Herein lies the issue: the vehicle is aggressively slowing down and pushing up on the right stalk (seemingly to disable D+) actually puts the vehicle into Reverse drive. This is because the vehicle does NOT require the brake pedal to be pressed to change into Reverse at low speeds (threshold unknown). This results in unpredictable and unexpected behavior of the vehicle within the matter of a few seconds. When the driver thinks they are disabling D+, they are unexpectedly putting the vehicle in reverse, so when accelerating from the stop caused by D+ the vehicle moves in reverse. This is most prevalent when using D+ in stop/go to light traffic and resulted in reversing on the freeway into another vehicle.
