2023 Rivian R1T Electrical System Problems

I Was driving down highway and receive a fe messages in quick order -front sensors off, front camera off, collision detection off, regenerative braking off - started moving toward right shoulder prior to pulling off - car lost speed at high rate putting me in jeopardy of being rear ended. 2025.06.012 code was loaded into truck the day before - this was first real drive after new code loaded into truck - early in the morning the warning for front sensors off, collision detection off, regenerative braking off did come and I pulled off and rebooted system. Everything seemed to be fine - made into office and again on return the loss of speed at high rate was a safety issue.

The vehicle caught fire and was completely destroyed. The fire was due to an electrical or battery system defect.

The contact owns a 2023 Rivian R1T. The contact stated while driving at approximately 70 MPH with the cruise control activated while overtaking another vehicle, the vehicle independently activated the brake. The contact had not turned off the cruise control and there were no other vehicles nearby. The contact stated no warning light was illuminated. The contact stated that when the other vehicle had passed the contact’s vehicle, the brakes disengaged, and the cruise control resumed and accelerated the vehicle back to the pre-set cruising speed. The contact stated that the failure was intermittent but had become a recurring failure. The contact had taken the vehicle to a service center; however, the failure could not be duplicated. The vehicle was not repaired. Additionally, the contact stated that when the vehicle fully charged the battery, the indicator showed that the vehicle was at 100 percent charge with a range of 369 miles. The contact was only able to drive a range of 260 miles on a full charged battery before needing to recharge the battery. The manufacturer was informed of the failure. The failure mileage was approximately 7,000.

I picked up this vehicle brand new from a Rivian service center. On the way home after approximately 90 miles, the screens lit up with a message saying Critical Battery Issue: Service Vehicle Immediately. In addition to the warnings on the console, there was a very loud beeping sound that did not stop. My understanding of the issue from speaking to Service and reading forums is that there is a software issue interacting with the battery which can cause this issue and eventually the vehicle to brick. It could cause a safety issue because in my case, it happened out of nowhere and forced me to pull over to the side of the road to protect myself and my family and the vehicle. In attempts to tow it to the service center, we also discovered that it was not possible to place the car in neutral which made it difficult to place on the tow truck. Had the car shut down entirely, I am not sure what the option would have been. To the best of my knowledge, Service has not officially diagnosed or determined the issue with my vehicle. Some of the information I have provided comes from research in online forums where others were encountering this problem at least back in 2022. It concerns me that there is still an issue especially as this was a brand new car and this manufacturer is attempting to ramp up production. It seems plausible there could be many more cars on the road soon and many/all contain this issue. There were no indications whatsoever before the message and noise began and I was driving down the highway at a normal and constant rate of speed.
