Campaign No. :	NHTSA ID	Campaign Desc. :		Transmission Wiring Harness Mounting
TBA	20V047	20P2197222
This is to notify you of a new Recall Campaign regarding the mounting of a fixing clip on a wiring harness of the automatic transmission in 28 Model Year (“MY”) 2019 GT-Class (290 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 February 3, 2020.
Background
Issue		Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY19 GT-Class vehicles (290 platform), the mounting of a fixing clip on a wiring harness of the automatic transmission might not meet current production specifications. If the wiring harness fixation clip is not mounted according to current production specification, the wiring harness might chafe against the drive shaft and become damaged over time. This could lead to an interruption of the electrical wires and then a loss of propulsion, resulting in a stalling of the vehicle and an increased crash risk. In addition, if a specific wire within the harness is damaged, the manual and automatic Park “P”-selection might not be available. However, the vehicle is still secured against unintended rolling with the electric parking brake.
What We’re Doing		MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will check the mounting of the fixing clip and the wiring harness on the affected vehicles and correct or replace them, if necessary.
Parts		A remedy is not yet available. An additional notification will be sent once a remedy is available.
Vehicles Affected
Vehicle Model Year(s)		2019
Vehicle Model		GT-Class
Vehicle Populations
Total Recall Population		28

Given this notice, it is a violation of Federal law for a dealer to sell or lease any new MY19 GT-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. Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent MY19 GT-Class vehicles covered by this notification until the vehicle has been repaired.
Next Steps/Notes
Customer Notification Timeline			Customer letter will be mailed approximately one week after the remedy becomes available.
AOMS/SOMS			AOMs – This recall may generate questions from your dealers. Please forward this notice to your dealers ASAP.

What is the CONCERN?	MBAG determined that on certain MY 19 GT-Class vehicles (290 platform), the mounting of a fixing clip on a wiring harness of the automatic transmission might not meet current production specifications. If the wiring harness fixation clip is not mounted according to current production specifications, the wiring harness might chafe against the drive shaft and become damaged over time. This could lead to an interruption of the electrical wires and then a loss of propulsion, resulting in a stalling of the vehicle and an increased crash risk. In addition, if a specific wire within the harness is damaged, the manual and automatic Park “P”-selection might not be available. However, the vehicle is still secured against unintended rolling with the electric parking brake. The driver will not receive an advance warning of incorrect mounting of the wiring harness fixation clips.   However, if the wiring harness is damaged and the vehicle cannot be shifted into Park, there will be a message displayed in the instrument cluster.
What will your DEALER DO?	An authorized Mercedes-Benz dealer willl check the mounting of the fixing clip and the wiring harness on the affected vehicles and correct or replace them, if necessary. This service will be provided free of charge. We are dedicated to always delivering the best customer experience, and respect for your time is a top priority. While the minimum repair time can be less than 2 hours, your dealer can provide you with a better estimate of the overall time for this service visit.  As a matter of normal service process, an authorized Mercedes-Benz dealer will also check for other repair measures which might be applicable to your vehicle which may increase the required working time.
What should YOU DO?	For additional information and to schedule an appointment, please contact your preferred authorized MercedesBenz dealer at your earliest convenience.  To locate authorized dealers see  www.MBUSA.com/recall. Please mention you are scheduling an appointment to have the mounting of a fixing clip on a wiring harness of the automatic transmission checked under Recall Campaign # 2020020016.
