Daimler Truck North America, LLC (DTNA) discovered that a 2022 Western Star truck does not meet certain safety standards for electronic stability control. They believe this is not a significant safety issue because the system is only turned off in off-road settings where it’s less effective. DTNA has requested that they not be penalized or required to notify owners about this noncompliance, as they argue that disabling the system is necessary for safe driving on uneven terrains. The National Highway Traffic Safety Administration (NHTSA) has received this petition and is considering DTNA’s request.
Simple Explanation
Daimler Truck found that one of their trucks doesn't meet a safety rule for keeping the truck steady on the road, but they think it's not a big deal because the feature is turned off when the truck is off-road. They asked a government group to agree with them so they don't have to warn owners.
