Campaign No. :	NHTSA ID	Campaign Desc. :		Check Rear Spoiler
TBA	20V480	20P2197284
This is to notify you of a new Recall Campaign to check the rear spoiler in 10,644  Model Year (“MY”) 2020 GLB-Class (247 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 21, 2020.
Background
Issue		Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2020 GLB-Class vehicles (247 platform), the rear spoiler located above the tailgate might have been manufactured outside specifications. The upper surface of the rear spoiler might not have been welded correctly, or not welded at all to the base part.  In the event of missing welds, it is possible that the upper surface might not be sufficiently connected to the base part. Should the rear spoiler be incorrectly welded, parts of the rear spoiler could detach while driving which could increase the risk of a crash for other road users. In the event of insufficient welds on the spoiler, the customer might be made aware of the issue by a noise when opening the tailgate, by scratches in the surface coating of the roof in the area of the tailgate, or by an improperly-fitting rear spoiler.
What We’re Doing		MBUSA will conduct a voluntary recall.  An authorized Mercedes-Benz dealer will check the rear spoiler on the affected vehicles and replace if necessary.
Parts		Remedy is not available at this time. An additional notification will be sent once the remedy is available.
Vehicles Affected
Vehicle Model Year(s)		2020
Vehicle Model		GLB-Class

Given this notice, it is a violation of Federal law for a dealer to sell or lease any new  MY20 GLB-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  MY20 GLB-Class vehicles covered by this notification until the vehicle has been repaired.

Campaign No. 2020090006, October 2020
Revision A 8/23/2021

 

TO:	ALL MERCEDES-BENZ CENTERS
SUBJECT:	Model GLB-Class vehicles (247 platform) Model Year 2020 Check Rear Spoiler

 

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2020 GLB-Class vehicles (247 platform), the rear spoiler located above the tailgate might have been manufactured outside specifications. The upper surface of the rear spoiler might not have been welded correctly, or not welded at all to the base part. In the event of missing welds, it is possible that the upper surface might not be sufficiently connected to the base part. Should the rear spoiler be incorrectly welded, parts of the rear spoiler could detach while driving which could increase the risk of a crash for other road users. In the event of insufficient welds on the spoiler, the customer might be made aware of the issue by a noise when opening the tailgate, by scratches in the surface coating of the roof in the area of the tailgate, or by an improperly-fitting rear spoiler. An authorized Mercedes-Benz dealer will check the rear spoiler on the affected vehicles and replace if necessary.

 

Prior to performing this Recall Campaign:

• VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns, and perform accordingly.
• Please review the entire Recall Campaign bulletin and follow the repair procedure exactly as described.

 

Please note that Recall Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.

Check/test procedure 

 

1. Open tailgate and apply masking tape to roof edge between left and right roof railings. (Figure 1) The masking tape is applied to protect the paintwork.

Figure 1

 

2. Lay out gauge with 5 mm.

• g. feeler gauge (Figure 2)

 

Figure 2

 

3. Carefully attempt to slide the gauge between the outer shell and the spoiler lip.

• It must not be possible to slide the gauge between the spoiler lip and the outer shell of the center rear spoiler. (Figure 5, not OK)
• The test must be performed along the length shown (A, Figure 4), starting from the roof center and extending approx. 100 mm to the left and right roof railings.

 

Figure 3 (OK)

 

Figure 4

 

Figure 5 (not OK)

 

4. Open tailgate and carefully check at a distance of 30 mm to the left and right of the edge in the test area (B, Figure 6) whether the gauge can be slid between the outer skin and the spoiler lip.

• It must not be possible to slide the gauge between the spoiler lip and the outer shell of the center rear spoiler.

Figure 6

 

5. Carefully pull on the spoiler lip in the area of the hinges on the left and right of the tailgate. The spoiler lip must not detach from the outer shell of the center rear spoiler.

Figure 7

 

6. Open and close tailgate and check whether the spoiler lip brushes against the seam seal in the area of the roof edge (C, Figure 8).

Minimal brushing without the spoiler lip snapping is acceptable.

The test must be performed along the entire length of the seam seal.

Should the spoiler lip have been damaged by the collision the complete center rear spoiler must be replaced.

Figure 8

 

7. Check whether the retaining clip in the center of the center rear spoiler is engaged.

To do so, fully open the tailgate and then lower it by 25 cm. The test is meaningful only in this position.

While the tailgate is open, press against the center rear spoiler from the inside with your thumbs (force applied: approx.10 lbs.).

If the center rear spoiler can easily be pressed against the roof edge the center retaining clip is not engaged and possibly damaged.

Figure 9

 

a. The gauge can be inserted between the spoiler lip and the outer shell or the spoiler lip can be detached from the outer shell or is damaged: Carry out work procedure A. (includes work procedure B operation steps)

b. The spoiler lip brushes heavily against the sealing seam: Carry out work procedure B.

c. The center retaining clip is loose: Carry out work procedure C.

d. No fault on center rear spoiler: End measure.

 

 

Work procedure A

 

1. Replace center rear spoiler (AR72.20-P-4000MFD).

Also replace mounting screws, retaining clips, and adhesive strips.

For vehicles with bonded additional accessory roof spoiler at rear spoiler, this must also be replaced.

Parts table and operation item table must be observed.

For basic data for accessory roof spoiler at rear spoiler, see AZ88.30-P-0015MFX.

 

 

Work procedure B

 

1. Adjust gap dimension between tailgate and roof edge to 7 mm.

Figure 10

 

2. Check again whether the spoiler lip brushes against the seam seal in the area of the roof edge (C, Figure 8).

Minimal brushing without the spoiler lip snapping is acceptable.

The test must be performed along the entire length of the seam seal.

Should the spoiler lip still brush heavily against the seam seal, the seam seal must be removed or replaced in the collision area. (To do this, the tailgate must be removed)

The paintwork structure must then be applied in accordance with the Mercedes-Benz specifications.  Carry out work procedure D.

 

 

Work procedure C

 

1. Remove center rear spoiler and replace all retaining clips, screws, and adhesive strips. For basic data, see AR72.20-P-4000MFD.

1. Remove tailgate (AR72.20-P-1020MFX).

 

2. Rework or replace seam seal on roof edge.
