The software program Over-the-Air (OTA) repair has already been put in on 85%, and counting, of the affected 7800 early Rivian R1T and R1S automobiles. It’ll save the automaker from requiring house owners to go to service facilities or deploy cell service items. On the similar time, it can fulfill the NHTSA recall, although Rivian will provide house owners a {hardware} substitute accelerator if desired.

In these early Rivian automobiles produced from June 10, 2021, to October thirty first, 2022, in excessive warmth, the sure accelerator pedal half can be activated to slowly transfer the car ahead very similar to an idling ICE car. The NHTSA describes it:

Drawback Description:
Rivian Automotive, LLC (Rivian) is recalling sure 2022 R1T and R1S automobiles. The accelerator pedal could not detect when the motive force releases the pedal, failing to activate “auto-hold” or “park” as meant.
Consequence:
Failure to activate “auto-hold” or “park” may end up in unintended car motion, growing the danger of a crash.
Treatment:
Rivian has launched an over-the-air (OTA) software program replace. Rivian will even exchange the accelerator pedals, freed from cost. Proprietor notification letters are anticipated to be mailed in February.

No accidents or accidents associated to the issue have been reported and certainly many house owners gained’t remember that the car isn’t behaving appropriately, particularly if they’re coming from an ICE car that does this naturally.

Rivian laid out the next bullet factors:

  • The recall contains 7,873 R1T and R1S automobiles assembled within the Regular, IL plant between June 10, 2021, and October 31, 2022, with an early revision accelerator pedal that won’t conform to efficiency specs. 
  • When uncovered to very excessive inside cabin temperatures, affected automobiles could not mechanically go into auto-hold or park when the motive force lifts their foot off the pedal. In excessive circumstances, the situation could trigger the car to creep ahead very slowly, approximate to an analogous ICE car at idle.  
  • We had been in a position to affirm the difficulty via our cloud telemetry information, and fewer than per week after figuring out the difficulty, we developed and deployed an OTA software program replace to affected automobiles that eradicated the priority. We will even be changing the accelerator pedal in affected automobiles for free of charge to our clients.  
  • We aren’t conscious of any accidents or accidents because of this subject.

I spoke to Wassym Bensaid, Rivian’s head of Software program Engineering concerning the repair and he laid out the way it got here to Rivian’s consideration – via a buyer go to. Rivian then hung out isolating the difficulty with its fleet of automobiles and was in a position to establish the problematic half. Rivian then was in a position to construct and take a look at a repair, first domestically then OTA on take a look at automobiles.

He wasn’t in a position to share what temperature invoked the scenario however labeled it as excessive warmth.

He mentioned the repair was constructing a software program patch that acknowledges the habits and eliminates the acceleration. That repair has been deployed and at present virtually all (85%) of affected automobiles had been technically fastened earlier than the NHTSA issued the warning this morning. Wassym famous that NHTSA labored with Rivian to verify the repair glad the repair necessities.

Electrek’s Take:

This is among the most excessive examples of software program fixing a {hardware} drawback within the auto business I can recall. If it weren’t for Rivian’s totally built-in software program stack and OTA capabilities, one thing like this couldn’t even have been tried. House owners can be compelled to go to a service middle and Rivian would have incurred a a lot higher value.

Tesla, in fact, has had a management function on OTA/full software program stack possession and has seemingly fastened NHTSA remembers month-to-month with software program updates, together with its Autopilot nag just some weeks in the past. This has led legacy automakers like Ford and GM to scramble to get their automobiles on board with these capabilities.

However it gained’t be simple for Legacy Auto to catch up. Right here’s Ford CEO speaking about this drawback (on the 25-minute mark) and the way he’s needed to re-invent the entire firm to take action:

“They don’t discuss to one another. So despite the fact that it says ‘Ford’ on the entrance, I’ve to go to Bosch and get permission to vary their seat-control software program.”
