Top issues to watch for
The most serious Mercedes Benz Sprinter problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Structural corrosion at mounting points
Commercial Sprinter vans develop severe structural corrosion at body mounting points, subframe attachment areas, and chassis rails. This affects the fundamental structural integrity of the vehicle and presents a serious safety risk. The MOT data shows this model fails structural rigidity tests at 95.6 times the national fleet average, indicating a widespread and severe problem across all generations. Salt exposure from winter road treatment and high-mileage commercial use accelerate the corrosion process.
What happens if ignoredStructural corrosion can lead to complete failure of mounting points, potentially causing loss of control or body separation from the chassis. The vehicle becomes unsafe to drive and will fail MOT tests. Repair typically requires welding new sections or complete chassis replacement, often costing more than the vehicle's value.

Dangerous
Brake system deterioration
Sprinter brake systems show multiple failure modes including flexible brake hose deterioration (75.3x fleet average failure rate) and overall brake efficiency problems (83.4x fleet average). The demanding commercial duty cycle with heavy loads and frequent stop-start driving accelerates brake component wear. Brake hose failure is particularly dangerous as it can cause complete loss of braking on affected wheels.
What happens if ignoredBrake hose failure can cause complete loss of braking on one or more wheels, creating an extreme safety hazard especially when the vehicle is loaded. The vehicle should not be driven if brake system integrity is compromised. Emergency repairs may be required to make the vehicle roadworthy.

Major
Body panel corrosion and damage
Sprinter vans suffer extensive body panel corrosion that creates sharp edges and poses injury risk during loading and unloading. The MOT data shows failures for dangerous body panel condition at 424.8 times the national fleet average. Rear doors, side panels, and wheel arches are particularly affected. This is exacerbated by the commercial nature of these vehicles which often operate in harsh conditions with minimal body protection.
What happens if ignoredSharp corroded edges present injury risk during commercial use. Extensive corrosion leads to MOT failure and can compromise weatherproofing of the load area. Repair costs escalate quickly as corrosion spreads, often requiring panel replacement rather than patching.

Major
Suspension component wear
Commercial Sprinter vans experience accelerated wear of suspension bushes, joints, and pins due to heavy loading and commercial use patterns. MOT data shows suspension component failures at 102.5 times the national fleet average. Front anti-roll bar drop links, rear leaf spring bushes, and shock absorber mounts are particularly affected. The high failure rate reflects the demanding commercial duty cycle these vehicles endure.
What happens if ignoredWorn suspension affects vehicle stability, increases tyre wear, and can lead to loss of control when heavily loaded. MOT failure is likely if wear becomes excessive. Commercial insurance may be affected if the vehicle is deemed unsafe for load carrying.
