What's wrong?
The intake and exhaust camshafts in these 2015-2016 Mercedes-Benz Gla 250, SLK300, and CLA250 vehicles are rotating engine shafts that control when the engine valves open and close. Those valves let air in, route exhaust out, and keep the engine breathing in the right rhythm while it runs.
On the recalled vehicles, the weld on certain camshafts was not placed in the intended position. Mercedes-Benz traced the problem to a supplier welding laser fixture that was not secured correctly after maintenance. If the weld fails, the camshaft can lose its correct alignment or strength, and the engine can be damaged.
There is no warning sign before failure. An owner should not count on a warning light, noise, or change in engine feel to appear before the camshaft weld gives way.
Who's affected?
Spans the Gla 250, SLK300, and CLA250 across the 2015 and 2016 model years, all tied to the same engine component.

Mercedes-Benz uses its general reimbursement plan on file for owners who already paid for related camshaft or engine damage repairs before the recall repair. Bring repair orders, payment records, and any diagnosis paperwork to the service desk so the dealer can help route the claim.
