TBA	20V107	20P2197234
This is to notify you of a new Recall Campaign regarding the internal contacting high-voltage battery in 1 Model Year (“MY”) 2019 smart EQ (453 platform) vehicle. 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 March 2, 2020.
Background
Issue		Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on a certain Model Year (“MY”) 2019 Smart EQ fortwo electric drive vehicle (453 platform), the cell-internal welding of the main cell conductors (connecting the individual cells and cell modules) of the high-voltage battery might not meet current production specifications.In case of an insufficient welding of the main cell conductor, the welded joint might detach under thermomechanical loads or vibrations.  As a result, the electrical contact within a cell of the high-voltage battery could be interrupted, leading to immediate failure of the entire high-voltage battery.  This condition would lead to a loss of propulsion and therefore a stalling of the vehicle while driving. Depending on the characteristic of the detachment of the welded joint of the main cell conductor, an electric arc occurrence cannot be completely ruled out. In this case, neighboring cells could ignite thereby increasing the risk of fire.
What We’re Doing		MBUSA will conduct a voluntary recall.  An authorized Mercedes-Benz smart dealer will replace the high-voltage battery on the affected vehicle.
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		Smart EQ fortwo
Vehicle Populations
Total Recall Population		1
Total Vehicles in Dealer Inventory		0
Given this notice, it is a violation of Federal law for a dealer to sell or lease any new MY19 smart  EQ electric drive  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 smart  EQ electric drive vehicles covered by this notification until the vehicle has been repaired.
Next Steps/Notes
Customer Notification Timeline		Customer letter mailing timelines are pending.
AOMS/SOMS		AOMs – This recall may generate questions from your dealers. Please forward this notice to your dealers ASAP.

IMPORTANT SAFETY RECALL
This INTERIM notice applies to your vehicle, VIN:
Replace High-Voltage Battery
NHTSA Recall # 20V107

 

March, 2020

Dear smart Owner:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

Mercedes-Benz AG (“MBAG”), the manufacturer of smart vehicles, has decided that a defect which relates to motor vehicle safety exists in a certain Model Year (“MY”) 2019 smart EO fortwo vehicle. Our records indicate that your vehicle is the affected vehicle.

 

What is the Concern?

MBAG determined that on a certain MY 19 smart EO fortwo electric drive vehicle (453 platform), the cell-internal welding of the main cell conductors (connecting the individual cells and cell modules) of the high-voltage battery might not meet current production specifications. In case of an insufficient welding of the main cell conductor, the welded joint might detach under therrnornechanical loads or vibrations. As a result, the electrical contact within a cell of the high-voltage battery could be interrupted, leading to failure of the entire high-voltage battery. This condition would lead to a loss of propulsion and a stalling of the vehicle while driving, increasing the risk of a crash. In addition, depending on the characteristic of the detachment of the welded joint of the main cell conductor, an electric arc could possibly occur. In this case, neighboring cells could ignite thereby increasing the risk of fire.

An authorized Mercedes-Benz dealer smart dealer will replace the high-voltage battery on the affected vehicle.

Unfortunately, the parts to remedy this situation are not available. We are working to obtain the necessary parts as quickly as possible. As parts become available, we will send you another letter asking you to take your vehicle to an authorized Mercedes-Benz dealer to have the recall repair completed free of charge.

Should you have any concerns or questions regarding your vehicle before you receive the next recall letter when parts are available, please contact an authorized Mercedes-Benz dealer. If for any reason a dealer is unable to resolve your question or concern, we are always happy to hear from you. Please contact us at 1-800-367-6372. A new vehicle identification number (VIN)-based recall lookup tool, on our MEUSA.corn website, now offers a search function that will indicate whether a vehicle has been subject to a safety recall, and whether that vehicle has had the free remedy performed. Please visit www.MBUSA.com/recall.

If you are no longer the vehicle owner, or have a change of address, please complete the reverse side of this letter and return the complete letter in the enclosed envelope. If this is a leased vehicle and the lessor and registered owner receive this notice, please forward this information by first class mail to the lessee within 10 days to comply with federal regulations.
