Campaign No. : NHTSA ID Campaign Desc. : Spark Plug Replacement
TBA 21V124 21P2197360
This is to notify you of a new Recall Campaign launch regarding spark plug replacements on 7 MY 2020 118 (CLA-Class) 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 March 5, 2021.

Background

Issue Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2020 CLA-Class (118 platform) vehicles with a 4-cylinder gasoline engine (M139), an incorrect variant of the spark plug might have been installed. In this case, an increased mechanical wear of the spark plug from thermal overload could occur over time. This may cause parts of the spark plug to possibly detach within the combustion chamber, potentially leading to engine damage. In this case, stalling of the vehicle cannot be ruled out, which could increase the risk of a crash.
What We’re Doing MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will replace the affected spark plugs on the affected vehicles.
Parts An additional notification will be sent when the remedy is available.
