Gear lash. I suppose there is a less than perfect analogy to a traditional ICE vehicle where the play in a universal joint on the drive shaft increases as the universal joint ages and is about to fail. Visits to the SC and driving around with a tech in the R1T really did not show the severity of...

Living in Northern Arizona they use cinders on the roads in the winter time. The cinders sometimes get in the disk brakes and also dirt from the forest roads all of which results in load noises on occasion. A trip through the car wash has always solved it for me.

I live in Northern Arizona, cold winter temperatures and snow. I saw a definite correlation between cold/warm temperatures (trips to Phoenix and summer heat) and the gear lash. While not an automotive engineer my belief is the heat thins the lubricant and also expands the metal changing the gear...

Trouble began at 3,000 miles. At around 12,000 miles Rivian took it back.

Had a LE QM R1T and over months went through all the interim “repairs” (new lube, washers, bolts, tightening, sub frame, etc.) and finally a front drive unit replacement, all to no avail. The only thing that worked was to receive a new replacement DM R1T. Life is good now.

Yes. R1T DM. 5,500 miles. Home service appointment scheduled April 2 to replace the 12 V battery and check the hub bolts.

My first R1T was a LE QM. At 3,000 miles it started having all the front drive unit/half shaft problems and repairs (including front frame replacement) non of which helped. At 12,000 miles after much unpleasant “discussions” with Rivian they agreed to take the vehicle back and replace it but...

For this purpose is there a difference between an OBD2 adapter and an OBD3 adapter? I have seen references to both on postings.

The HVAC systems in the Rivians have been disasters from the beginning. My LE QM R1T malfunctioned continuously whether on AC or heat. I always had to run it on manual. The SC had no answers speculating it was a software and/or sensor issue. That vehicle was replaced by Rivian (drive unit/half...

I had the driver’s door sensor fail. After replace everything has been fine.

Had my R1T for about a year. The FM radio is haunted. When I park the vehicle in the garage at night with the FM radio on, as one would expect, it turns off along with the rest of the vehicle presumably to help limit vampire drain. In the morning when I pull out of the garage sometimes the radio...

Has anyone tried traditional heated automotive snowplow lights?

I have often wondered if in those situations where most Rivian owners have no problems with a given update and some do could the transmission process itself (cell tower/WIFI) be corrupting the code? My cell tower reception at home is not the best but my home WiFi is very reliable so I always use...

My first R1T was a Launch Edition with 20” AT’s. The first half of the first winter Rivian had not yet released “Snow Mode” and living at 7,000 feet with winter snow and ice it was a white knuckler to drive. The release of snow mode made it a real pleasure to drive. My second R1T is a DM with...

I added SXM radio to my R1T with the FM adapter and receiver. To my tired old ears the quality of sound is certainly acceptable and not needing to rely on cell tower coverage is a blessing. But I am not one to preload music on my cellphone in order to BT it to my truck. Something about “Old dogs...

I have had two R1T’s the first a LE QM and the second a DM. The LE’s HVAC was absolutely terrible. I usually ran it on manual, rather than auto, which helped. The DM has been an improvement but I still find manual less frustrating. While a pure guess on my part I think it has something to do...

Last time I checked there are only two ways to receive SXM in your Rivian, either through the SXM app on your cell phone with BT connection to the infotainment center or install an SXM receiver and antenna with a FM radio adapter. The Rivian infotainment center does not recognize nor pair with...

My first R1T was a LE QM. At around 3,000 miles the gear lash, marbles in a tin can noises started and notwithstanding numerous repairs (including front drive units) continued to get worse. At 12,000 miles I was finally able to get Rivian to replace it. I refused a QM replacement R1T. My...

Perhaps an out of balance fan? My R1T DM did this once after a few hours on a dusty forest road. Not sure if it fixed it but after a trip through a car wash it has not come back.
