Karma Automotive is recalling 2018 Revero models and has issued a stop-sale for the car after discovering that the vehicle’s rollover sensors haven’t been enabled, which is indeed a serious problem.

A notice from the National Highway Traffic Safety Administration (NHTSA) states that, in the event of a rollover crash, the side curtain/head protection airbags may not deploy because the rollover sensors haven’t been enabled. It is also reported that the Revero lacks a warning light to inform drivers that the sensors aren’t enabled and that no description of the rollover sensors are provided in the owner’s manual.

The car manufacturer discovered that the rollover sensors on 2018 Revero models hadn’t been enabled during compliance testing of the forthcoming 2020 Karma Revero on April 4, 2019. It was also determined on that date that the rollover sensors on 2020 models also hadn’t been enabled.

Karma says it hasn’t received any reports of injuries or deaths relating to the issue, nor has it been notified about any warranty claims relating to it.

The recall impacts 231 examples of the 2018 Revero which were built on or after September 1, 2017. Revero models built before this date won’t be recalled, as these vehicles have a small-volume manufacturer federal exemption.

Karma intends on informing owners about a fix to the issue by July. The remedy consists of replacing the current airbag control unit with one that has enabled rollover sensors. An indicator will also be added to monitor the readiness of the system, while an update will be made to the owner’s manual.
