Rivian was not the only electric vehicle startup to feature in my weekly recall email from the National Highway Traffic Safety Administration this morning. Electra Mecchanica and Lordstown are recalling a small number of EVs, but, more significantly, Tesla has issued yet another recall, and this time there's no software patch that can remedy the problem; affected cars have to be physically inspected.

Tesla is recalling 3,470 Model Y crossovers built between May 2022 and February 2023 to check that the bolts that secure the frame of the second-row seats are properly torqued. Those that aren't could potentially increase the risk of injury to occupants of the second row during a crash.

For owners worried their cars may be affected, Tesla says that a "second-row seat back frame that has this condition may not fold properly or may be loose and rattle during normal vehicle operation."

Rivian is in the process of recalling nearly 13,000 R1T trucks and R1S SUVs due to a potential seatbelt problem. It believes that in some vehicles, a sensor within the seatbelt system is missized or "dimensionally out of tolerance," which could prevent the automatic locking retractor from working properly. That, in turn, could lead the front passenger airbag to believe the seat was unoccupied during a crash and fail to trigger.

Last July, Rivian and its supplier were investigating a vehicle displaying a message that the front passenger airbag was off despite having a passenger in that seat. Rivian and its supplier, Autoliv, worked on the problem until January, collecting more potentially suspect parts from other Rivian EVs. In February, the startup determined that vehicles with the suspect parts would not be compliant with federal safety regulations and initiated the recall.

Unlike many problems we see on new EVs, this one is not the sort that can just be fixed with a software patch. Although Rivian thinks that only 1 percent of the 12,716 affected cars have a defective part, it will inspect and, if necessary, replace the passenger seatbelt components in those affected vehicles.

Volkswagen is the latest OEM to issue a recall for some of its electric vehicles. This time the problem afflicts the MY2021 ID.4, VW's EV crossover. The problem concerns the battery management control module, as well as the pulse inverter control module. This version of the battery management control unit software can be too sensitive and reset itself in some circumstances, and the pulse inverter control module can, under rare conditions, deactivate if there's a software failure.

VW first had an inkling there was a problem in July 2021 when reports started coming in of potential problems with the high-voltage battery management software. By September 2021, VW had concluded there was no unreasonable risk to drivers but continued studying the problem. By January 2022, VW's supplier told it that the pulse inverter software had problems, too.

Last summer VW went through feedback questionnaires from ID.4 owners and found that "some reports from the US market indicated that the battery management software issue could have led to stalling allegations."
