What the fix does
This page covers 6 recalls and 54 owner complaints for the 2014 Mercedes-Benz Sprinter 3500.
The dominant complaint pattern for the 2014 Mercedes-Benz Sprinter 3500 centers on the airbag system and cruise control. Airbag complaints make up the largest share of reports, with owners describing warning lights, system faults, and concerns about whether the airbags would deploy as intended. Wheel speed sensors draw consistent complaints as well, owners report them failing repeatedly, sometimes every few months, which triggers ABS warning lights and can cause the transmission to downshift unexpectedly at highway speeds. Cruise control and vehicle speed control also come up frequently, with owners describing sudden surges or unexpected speed changes while driving. A smaller cluster of brake complaints rounds out the picture. The wheel speed sensor issue stands out for its reported recurrence, multiple owners describe replacing the sensor only to have it fail again within a short period.

By System
The 2014 Mercedes-Benz Sprinter 3500 has 6 recalls, the most serious being defective airbag inflators on both the driver and passenger sides that can rupture in a crash and send metal fragments into the cabin, causing serious injury or death.
The airbag system has a third concern as well: certain vehicles were built without a reinforcement plate and protective bracket on the airbag control unit, which can prevent secondary airbags from deploying in a crash. On the engine side, oil can leak from the chain tensioner gasket area and drip onto hot engine surfaces, raising the risk of an engine fire, and the leaking oil can also create a hazard for other vehicles on the road. There is also a stability concern affecting vehicles that have been upfitted into campers or recreational vehicles: the electronic stability control module can become disabled, reducing the vehicle's ability to maintain control in certain driving situations. Finally, also on upfitted camper variants, the onboard fire extinguisher may fail to function properly in the event of a fire.
