2022 Rivian R1T

When towing a trailer with my Rivian R1T on interstate 75 I set my cruise control while going with the speed of traffic at approximately 60 mph. Instead of cruise control setting at the speed I was traveling, it instead sets at the posted speed limit. In most conditions, this wouldn't create a hazard as adaptive cruise control would keep the vehicle from accelerating more than the speed the vehicle directly in front of me is going. But when towing a trailer, the R1T disables the adaptive part of cruise control as well as emergency braking. Setting cruise control in this circumstance nearly cased me to rear end the car in front of my as I wasn't expecting the cruise control to set at nearly 10 mph faster than I was traveling when I set it. To be clear. This is not "resuming" a previous cruise control speed I had been set to, this sets at the posted speed limit.

What component or system failed or malfunctioned, and is it available for inspection upon request? MANY components of the vehicle that run on software are completely unuseable. This includes ALL sensors, safety features, ADAS, ability to adjust suspension, regen braking, HVAC, Audio, etc. How was your safety or the safety of others put at risk? I do not know what is working and what is not working. Zero sensors are working. Are the regen brakes working? I do not know. Are my turn signals working or headlights on? I have no way of telling. Not having the ability to adjust suspension, drive mode, etc. is also concerning. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, confirmed by Rivian support and confirmed that it is VERY widespread. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. Happened after a failed OTA software update.

Front passenger seat does not always recognize that a passenger (my wife who weighs about 110 lbs) is sitting in the seat. The airbag off light will be on during various parts of a trip when my wife is clearly sitting normal in the seat with her belt buckled. I’ve brought the vehicle in twice to the manufacturer for them to fix the issue and both times they have stated that they can’t find a problem. I have video and shared with them both times. I feel uncomfortable allowing my wife to sit as a passenger knowing she isn’t being fully protected with airbags ready to deploy. Please help fix this problem. Thanks

On 9/23/23 at approximately 4:10pm, my Rivian R1T suffered a catastrophic failure of the left rear brake. After exiting the freeway, I was slowing for a traffic signal primarily using the regenerative brake feature. I applied light pressure to the brake pedal which initiated a left rear brake failure. I attempted to move the truck out of the traffic lane. The left rear wheel was locked and would not roll. Upon removing the aero cover from the wheel, I observed the brake caliper in an abnormal position. The wheel had a sizeable hole in the middle of it. I surmised that the brake caliper shifted position during braking and damaged the wheel. The vehicle was towed to the Rivian Service Center in Phoenix, Az. A representative at the Service Center has told me that the wheel would not roll because the brake caliper shifted into the center of the wheel preventing it from turning. They have withheld further information about the root cause until they can investigate further. Had this event occurred at higher speeds, I have no doubt it would have caused a loss of control of the vehicle when the wheel locked or perhaps as a result of an inability to slow the vehicle. Rivian is still investigating the root cause of the brake failure. The only warnings received occurred after the event. I was presented with a Parking Brake Service Needed warning, and an indicator that no drive modes could be selected.

Loses sight of vehicle ahead and will accelerate to set speed ignoring vehicle in front when in bends. It only seems to track vehicles in a straight line of sight ahead and not accommodate for steering. It’s most obvious on curves in highways and can easily be reproduced on cloverleaf on ramps or off ramps or even at low speeds when going around an obstacle.

ACC phantom brakes on highways causing dangerous situations with vehicles following behind and also causing driver panic events particularly when phantom braking occurs most commonly on bends of highways or on single lane highways where it reacts to oncoming traffic. The most common way phantom braking triggers is while traveling on single lane highways with shoulders where there are objects on the side of the highway (either parked cars, trailers, or large structures) particularly when coming around a curve or bend (most unreliable on mountain highways). It will quickly react and cause the Rivian to rapidly brake/decelerate. When occuring on highways with bends it can cause unexpected reactions from cars following behind not expecting sudden braking of the vehicle ahead mid bend. The best way to mitigate is to apply pressure to the accelerator pedal to override the braking. It has happened numerous times since our ownership started 2 months ago. It’s received 3 over the air updates in that time and it continues to have phantom braking with update 2023.34.0.

Was driving through an intersection in traffic when I heard a loud explosion/metal-on-metal sound from the front drivers side of the vehicle. Instantly received two warnings in the IP; one for "Performance Limited" and the other for "Service Suspension Soon". The IP also stated speed was limited to 80MPH. I didn't notice any difference in driving but decided to pull over and check. Upon checking I identified a hydraulic suspension line completely disconnected and leaking hydraulic fluid in the front driver side wheel well. The wheel well also appeared to be covered in hydraulic fluid. Over the next 10-15 minutes the suspension became uneven/lopsided and the passenger side wheels were touching the wheel well. I called Rivian service and they said it was not safe to drive and had it towed to the Rivian service center. Rivian service is backlogged and will not be able to inspect and assess the damage until 9/21. Ultimately, I don't think the warnings accurately conveyed the severity of the issue and don't understand why the vehicle would let you drive up to 80mph when rivian service said it was not safe to drive.

Recent interaction with a driver alongside my vehicle. Driver begin merging into my lane. Used horn as well as decelerating to prevent collision. It appears horn was unheard by other driver. Believe the fact the horn is mounted very low on my vehicle and ducted in a way that it is not sufficiently loud to alert other drivers and prevent accidents Other posts on the Rivian forum note other Rivian drivers experiencing same issue with horn volume.

Critical battery issue, made the truck inoperable and stuck in my garage. Rivian replaced the main battery pack and the drained 12v batteries. One day after getting the truck back while I was driving, the truck motors stopped in a jarring fashion in the middle of dark one lane road. Error message said motor failure. Then got the same critical battery issue. Once the main battery dies it drains the 12v batteries; thereby, turning off the emergency lights. There is a major issue with the battery packs. It is incredibly dangerous that the motors shut down not allowing me to coast and move the truck to a safe spot. The 12v draining when there is a main battery pack failure; thereby, shutting off the emergency lights in a design flaw.

We purchased our Rivian two weeks ago today from a private seller, and Rivian will not transfer ownership of the truck to us despite multiple calls, emails, and online chats. This is a safety, security, and privacy issue. There is a major recall that I cannot get fixed because Rivian will not transfer ownership of the vehicle from the previous owner to us. The previous owners have access to the vehicle, being able to disable our keys, and could access our vehicle at any point should they so desire. They can view all recordings from the truck, which means they are accessing private conversations and communications occurring in my own private garage. We've made it abundantly clear to Rivian that this is a security and safety issue, but they will not remedy the matter by transferring ownership (the truck is currently registered in the state of Florida, and the taxes, title, and tags have all been processed.
