The Problem: Rear taillights in certain Mercedes-Benz C-Class models can dim or totally shut off as a result of bad electrical connections. The ground pin connector can oxidize over time and cause the malfunction, impairing the taillight and rear turn signal’s effectiveness.
The Fix: Once parts are available, Mercedes-Benz dealers will replace corroded connectors at no cost to the customer. Owners should get an initial notification in June, to be followed by another notification once parts are available in August or September.
Number of Vehicles Potentially Affected: 252,867 Mercedes-Benz C-Class vehicles from 2008-2011.

The Problem: The four aluminum bolts for the variable camshaft timing adjustment assembly on the intake and exhaust camshafts can loosen or break over time due to a quality fault. In the event of such an incident, engine power would be reduced and a stall is possible. A check-engine light or check-control message would appear, and Limp-Home mode would activate. BMW says drivers might not be able to restart the engines after this problem occurs.
The Fix: Beginning in May, BMW dealers will inspect and if necessary replace the aluminum camshaft housing bolts for free. Although 2010-2012 BMW vehicles with inline-six engines were not recalled, these vehicles will be granted an extended warranty in acknowledgement of the issue. Only about two percent of cars included in the recall are believed to actually have the problem, but all will be inspected.
Number of Vehicles Potentially Affected: 156,137 BMW vehicles across the 1-, 3-, 5-, Z-, and X-Series.
