Recalls
4 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Engine & cooling Vehicle recall #15V662000 · 2015 · 857 vehicles
What's wrong: The affected vehicles have intake or exhaust camshafts whose welds May fail and possibly cause engine damage.
Why it matters: Engine damage May result in a stall, increasing the risk of a crash.
The fix: Mercedes-benz will notify owners, and dealers will replace the affected camshafts, free of charge. Interim notices were mailed to owners on December 9, 2015. The recall began on December 23, 2015.
Electrical Vehicle recall #16V211000 · 2016 · 223 vehicles
What's wrong: The backup power supply for the ignition switch in the affected vehicles May not have been properly connected. As a result, if the vehicle is being driven and there is a loss of power from the main vehicle battery, the transmission cannot be shifted to "park" nor can the electric parking brake be applied.
Why it matters: In this situation, without the backup power supply, the only way to keep the vehicle from moving is to press the brake pedal. As soon as the driver attempts to exit the vehicle, the vehicle May roll, increasing the risk of injury.
The fix: Mbusa will notify owners, and dealers will correct the ignition switch wiring and perform a software update, free of charge. The recall began on May 9, 2016.
Suspension Vehicle recall #16V306000 · 2016 · 327 vehicles
What's wrong: In the affected vehicles, improperly manufactured lock nuts May have been used on the rear wheel tie rod connection, and as a result, the rear wheel alignment May change and the rear axle May steer independently.
Why it matters: A change of the rear wheel alignment and independent steering of the rear axle May increase the risk of a crash.
The fix: Mbusa will notify owners, and dealers will replace the lock nuts on the rear tie rods, free of charge. The recall began on June 24, 2016.
Communication Vehicle recall #19V787000 · 2019 · 24,226 vehicles
What's wrong: Mercedes-benz USA, LLC. (mbusa) is recalling certain 2013-2017 vehicles due to a software fault that May cause the date and time for the emergency call system (ecall) to differ from the actual date and time, potentially relaying an inaccurate vehicle location.
