Top issues to watch for

The most serious Mercedes Benz E Class problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Major
Transmission shaft flexible coupling failure
W211, W2122002–201620k–150k miles
The flexible coupling (flex disc or giubo) connects the transmission output to the propshaft on rear-wheel-drive E-Class models. This rubber and steel component deteriorates due to heat cycles and torque stress, causing vibration and eventual complete failure. Mercedes E-Class models show MOT failure rates 188.7 times higher than the fleet average for this specific defect, with failures documented across all mileage ranges from 20,000 miles upward. The coupling is a safety-critical component - complete failure results in loss of drive and potential propshaft damage.
What happens if ignoredComplete coupling failure results in immediate loss of drive and potential damage to the propshaft universal joints or transmission output shaft. The propshaft may drop and cause dangerous handling or underfloor damage. Repair requires replacement of the complete flex disc assembly and inspection of adjacent driveline components.

Major
Excessive steering play
W2101995–200380k–150k miles
W210 generation E-Class models develop excessive free play in the steering system, typically due to worn track rod ends or steering damper failure. MOT data shows failure rates 134.9 times higher than the fleet average, concentrated in higher-mileage examples. The issue affects driving precision and can progress to dangerous levels where steering input does not translate to wheel movement, particularly problematic at motorway speeds.
What happens if ignoredExcessive steering play creates unpredictable handling and requires constant driver correction. In severe cases, steering response becomes dangerously delayed, particularly hazardous during emergency manoeuvres or at high speeds. Complete track rod end failure can result in loss of steering control on the affected side.

Wheel bearing wear
W210, W211, W2121995–201620k–150k miles
E-Class models show wheel bearing failure rates 55.2 times higher than the fleet average, with over 69,000 documented MOT failures. The issue affects both front and rear bearings across all generations, with some failures occurring as early as 20,000 miles. Mercedes uses sealed hub bearings that cannot be repacked with grease, requiring complete hub assembly replacement when they fail. Early failure may be linked to the heavier weight of E-Class models and their performance-oriented suspension geometry.
What happens if ignoredWorn wheel bearings cause noise, vibration, and reduced fuel economy. Severe wear can lead to wheel wobble and eventual bearing collapse, which would cause loss of the wheel and potentially catastrophic accident. Early replacement prevents more expensive damage to the hub assembly and brake components.

Major
Brake hose deterioration
W210, W211, W2121995–201640k–150k miles
Flexible brake hoses on E-Class models deteriorate at rates 26.8 times higher than the fleet average, with over 11,000 documented MOT failures. The rubber brake hoses connecting the rigid brake lines to the calipers are subject to heat cycles from the braking system and movement stress from suspension travel. Age-related deterioration causes internal rubber lining to break down, potentially blocking brake fluid flow or causing external leaks.
What happens if ignoredDeteriorated brake hoses can fail suddenly causing complete brake loss on the affected corner, or gradual deterioration causing reduced braking efficiency. Internal rubber breakdown can block brake fluid flow leading to brake fade or pedal loss. External leaks cause environmental contamination and progressive brake system failure.
