Lot 6501: 2014 Mercedes-Benz E350

The 2014 Mercedes-Benz E350 is generally a solid car, but there are some common issues to be aware of—especially since this is a cabriolet with low miles (about 19K).

Engine & Timing (M276 V6)

The M276 engine is pretty reliable, but has a few weak spots:

• Camshaft adjuster/timing chain tensioner – Can cause a rattle on cold starts. If you hear ticking when first starting, that’s your culprit. Check for service history on this.
• Valve cover gasket seepage – Age-related, not mileage-related. Worth checking for oil residue around the engine.
• Direct injection carbon buildup – Actually less of a concern on low-mile cars like this one.

Since this car’s only seen ~19K miles, the timing chain and internal wear items are likely in great shape. The facelifted 2014s also got some updates that improved reliability over early W212s.

Convertible-Specific Issues

Being a cabriolet, pay attention to:

• Hydraulic convertible top cylinders – The hydraulic seals can dry out from age, even with low use. Cycle the top a few times during inspection and watch for slow operation or fluid seepage.
• Drain tubes and seals – Check for water stains in the footwells. The drain tubes can clog and cause leaks during rain.
• Top latch mechanisms – Make sure they operate smoothly.

Other Common Spots

• Rust – Mercedes of this era are prone to rust behind the license plate and trunk areas. Worth a close look.
• Blower motor/HVAC – Heater fan issues occasionally crop up.
• Water intrusion – Check carpets for dampness around door seals and convertible top edges.

Age vs. Mileage

With only ~19,300 miles, this car avoided the typical wear items—but age becomes the enemy:

• Tires are likely original (check dates, they may need replacement due to age)
• Brake fluid and hoses should be checked/replaced
• Battery condition
• Rubber seals and gaskets throughout
