2007, 2008, 2009, 2010, 2014 Mercedes-Benz Recall 22V168: ECU

Recall 22V168 covers 22 Mercedes-Benz vehicles from 2007, 2008, 2009, 2010, and 2014 for incorrect control-unit software. Repair is free at any franchised Mercedes-Benz dealer.

What's wrong?

On 2007, 2008, 2009, 2010, and 2014 Mercedes-Benz E350, G550, SLK280, CLK550, SL550, SLK350, C300, and C350 vehicles, the affected parts are control units. These are small computers that manage engine operation, exterior lighting, stability control, traction control, and related vehicle functions. Each control unit needs the correct software configuration so it knows how to command the system it controls.

The problem began during a service repair, when a workshop diagnostic system wrote incorrect configuration data into one or more control units. That wrong configuration means the unit no longer matches Mercedes-Benz production specifications. Depending on which unit was changed, the vehicle can lose drive power, have reduced exterior lighting, or lose dynamic control functions, including stability and traction control.

The driver will not receive a dashboard warning before this software deviation causes a failure. There is no warning sign before failure, so a vehicle that seems normal still needs the recall repair if its VIN is included.

Who's affected?

The scope spans passenger cars plus the G550 SUV across the 2007, 2008, 2009, 2010, and 2014 model years, with engine, stability control, and lighting software listed separately.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.

What's the safety risk?

A loss of drive power, reduced exterior lighting, or loss of stability and traction control raises crash risk. There is no warning sign before the failure, so schedule the software update soon if your VIN is included. Repair is free at any franchised Mercedes-Benz dealer.

What should I do?

1. Check your VIN to confirm this recall applies to your Mercedes-Benz E350, G550, SLK280, CLK550, SL550, SLK350, C300, or C350 from 2007, 2008, 2009, 2010, or 2014.
2. Contact your nearest franchised Mercedes-Benz dealer to schedule the free control-unit software update that corrects system failures tied to incorrect service software.
3. Bring the recall notice if you have it. If not, reference recall number 22V168 when you call.
4. Drive cautiously until the repair is complete. Watch for loss of drive power, reduced exterior lighting, or stability and traction-control problems.

What happens at the repair

At the dealer, a Mercedes-Benz technician updates the software configuration on the affected control units. The recall repair is free, and parts and labor are covered. This update corrects control-unit settings that were changed incorrectly during a prior service repair. If you already paid out of pocket for this same condition before the recall notice, MBUSA's standard reimbursement plan covers documented expenses. Bring repair paperwork and payment records to the service desk when you arrive.
