| This is to notify you of a new Recall Campaign to replace the fuel tank on 3 Model Year (“MY”) 2019 G-Class (463 platform) vehicles. The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs will be flagged in VMI as “PENDING” on July 30, 2021. | ||||
| Background | ||||
| Issue | Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that based on information provided by the fuel tank supplier, the fuel tank on certain Model Year (“MY”) 2019 G-Class (463 platform) vehicles might not meet current production specifications. In this case, the welding seam where the two halves of the fuel tank are joined might not meet the fatigue strength requirements. As a result, the leak tightness of the tank cannot be ensured over the vehicle’s service life. The supplier has assessed that in the event of a fuel leak, the risk of a fire hazard due to an ignition source could increase. When the issue occurs, the customer might be made aware of the complaint by the smell of fuel and by a flashing check engine indicator light in the instrument cluster. | |||
| What We’re Doing | MBUSA is conducting a voluntary recall based on the Defect Information Report submitted by the supplier. An authorized Mercedes-Benz dealer will replace the fuel tank on the affected vehicles. | |||
| Parts | Remedy is not available at this time. An additional notification will be sent once the remedy is available. | |||

| Given this notice, it is a violation of Federal law for a dealer to sell or lease any new MY19 G-Class vehicles in dealer inventory covered by this notification until the vehicle has been repaired. Once the remedy is available, the vehicles will be flagged as “OPEN” and Work Instructions will be available in Star TekInfo. Once the repair is complete, the vehicle may be sold or leased.
Loaner and demonstrator vehicles may continue to be driven, but must not be retailed until repaired. As a matter of normal service process, please check for other repair measures which might be applicable to the vehicle(s)
