What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This recall involves loss of critical safety systems (anti-lock brakes and electronic stability control) that increase crash risk. No injuries or crashes have been reported, and the hazard is potential rather than confirmed, placing this at the high end of non-severe recalls.

Plain-English summary

Mercedes-Benz USA, LLC is recalling certain 2019–2021 G550 and AMG G63 vehicles. According to the recall notice, the front axle wiring harness may chafe against an oil cooler and become damaged.
