| This is to notify you of a new Recall Campaign to update the software for the seat belt warning in the instrument cluster in 56 Model Year (“MY”) 2017-2019 C-Class (205 platform), E-Class (213 platform), S-Class (222 platform), E-Class Coupe/Convertible (238 platform) and CLSClass (257 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 August 7, 2020. | ||||
| Background | ||||
| Issue | Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY17-19 C-Class (205 platform), E-Class (213 platform), S-Class (222 platform), EClass Coupe/Convertible (238 platform) and CLS-Class (257 platform) vehicles, the seat belt warning system does not meet current production specifications. If the driver or passenger seat belt is not fastened, the seat belt warning would not warn the driver as intended by means of a blinking warning lamp in the instrument cluster and an audible warning tone, but only with a permanently activated warning lamp. Thus, the driver would not receive the full scope of intended warnings in the event of an unfastened seatbelt. An unfastened seatbelt increases the risk of injury in the event of a crash. The customer may be made aware of the issue by the absence of the blinking warning lamp and the audible warning tone if the vehicle is driven without the seat belt fastened. | |||
| What We’re Doing | MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will update the (SCN) -Coding of the instrument cluster on the affected vehicles. | |||
