RE: Recall Campaign 2015100007 2015100008 2015100009 – Engine Camshaft Replacement, Model 117/156/172 (CLA-Class, GLA-Class, and SLK-Class) Model Years 2015-2016
DATE: December 16, 2015
IMPORTANT RECALL LAUNCH INFORMATION
This Recall Campaign is being launched today and the 857 affected vehicles will be flagged in VMI. Three separate campaigns have been created to clearly define the proper camshaft repair for each VIN: - 2015100007 (intake) - 2015100008 (intake and exhaust) - 2015100009 (exhaust) Parts: Dealers may order parts as required. Repair Time is approx. 8-9 hours. Currently, parts are available for the 117(CLA) and 156(GLA). The 172 (SLK) does not have all parts available yet. Information will be provided when they become available. Special Tools: All necessary tools specified in the Work Instructions must be on-hand before starting the repairs. Owner Notification: Owner notifications will be sent approximately late December, 2015. What Should Customers Do: Customers may continue to drive their vehicles until the recall is completed. Given this notice, it is a violation of Federal law for a dealer to sell or lease any new Model Years 2015-2016 CLA-Class, GLA-Class, SLK-Class vehicles covered by this notification in dealer inventory until the vehicle has been repaired. This notice provides the information for Dealers to start repairing vehicles. Once the repair is completed, the vehicle may be sold. Dealers are encouraged to check inventory vehicles for recall campaign applicability in VMI, and repair immediately. What’s the Issue: Daimler AG (DAG) has decided that on approximately 857 Model Years 2015-2016 CLA-Class, GLA-Class, and SLK-Class vehicles, the camshaft weld might have been manufactured outside of specfications, where the weld on certain camshafts may not have been placed at the intended position. In the affected vehicles, one or both camshafts could break and damage the engine, leading to a loss of power and causing the engine to stall. If this situation occurs, the engine cannot be restarted.
What We’re Doing: MBUSA has initiated a voluntary recall of all potentially affected vehicles described above. An authorized Mercedes-Benz dealer will replace the engine camshaft on the affected vehicles.
When scheduling customers for an appointment please ensure that you are aware of any open campaigns in VMI so that the customer is advised about the time necessary to complete all campaigns.
MERCEDES-BENZ USA, LLC 303 Perimeter Center North, Suite 202 Atlanta, GA, 30346 Phone: (770) 705-0600 Fax: (770) 705-0117 MBUSA.com
Note: VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle.
Dealers may also identify vehicles subject to a campaign through NetStar by selecting “Campaign” under the Controlling tab. Only vehicles that have been retailed by the respective dealer will be displayed within this program.
While we regret any inconvenience this may cause, MBUSA is determined to maintain a high level of vehicle quality and customer satisfaction.
Please refer all customer inquiries to the Customer Assistance Center at 1-800-FOR-MERCedes (1-800-367-6372).
Campaign No. 2015100007, December 2015
TO: ALL MERCEDES-BENZ CENTERS
SUBJECT: Models 117 (CLA) and 156 (GLA) with Engine 270, Model 172 (SLK) with Engine
274, Model Years 2015 - 2016
Replace Intake Camshaft
This Recall campaign has been initiated because Daimler AG (DAG), the manufacturer of Mercedes-
Benz vehicles, has determined that on certain Model Year 2015-2016 CLA, GLA, SLK vehicles equipped
with four-cylinder gasoline engines, a camshaft weld might have been manufactured outside of
specifications. Due to a production deviation at a supplier, the weld on certain camshafts may not be
placed at the intended position. The subject four-cylinder gasoline engines are designed with two
camshafts, one intake camshaft and one exhaust camshaft. In the affected vehicles the intake camshaft
could break and damage the engine until it stalls. If this situation occurs, the engine cannot be restarted.
An authorized Mercedes-Benz dealer will replace the intake camshaft on the affected vehicles.
Prior to performing this Recall Campaign:
Please check VMI to determine if the vehicle is involved in the Campaign and if it has been
previously repaired.
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.
Approximately 372 vehicles are involved. Order No. P-RC-2015100007 This bulletin has been created and maintained in accordance with MBUSA-SLP S423QH001, Document and Data Control, and MBUSA-SLP S424HH001, Control of Quality Records.

Campaign No. 2015100008, December 2015
TO: ALL MERCEDES-BENZ CENTERS
SUBJECT: Model 172 (SLK) with Engine 274, Model Year 2016
Replace Intake and Exhaust Camshafts
This Recall campaign has been initiated because Daimler AG (DAG), the manufacturer of Mercedes-
Benz vehicles, has determined that on certain Model Year 2016 SLK vehicles equipped with four-
cylinder gasoline engines, a camshaft weld might have been manufactured outside of specifications. Due
to a production deviation at a supplier, the weld on certain camshafts may not be placed at the intended
position. The subject four-cylinder gasoline engines are designed with two camshafts, one intake
camshaft and one exhaust camshaft. In the affected vehicles one or both camshafts could break and
damage the engine until it stalls. If this situation occurs, the engine cannot be restarted. An authorized
Mercedes-Benz dealer will replace the relevant camshaft on the affected vehicles.
Prior to performing this Recall Campaign:
Please check VMI to determine if the vehicle is involved in the Campaign and if it has been
previously repaired.
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.
Approximately 2 vehicles are involved. Order No. P-RC-2015100008 This bulletin has been created and maintained in accordance with MBUSA-SLP S423QH001, Document and Data Control, and MBUSA-SLP S424HH001, Control of Quality Records.
