Engine

3.0L V6

• Cylinder Head Corrosion: Premature corrosion of the cylinder heads can cause coolant leaks, overheating, and engine damage.
• Intake Manifold Gaskets: Leaking intake manifold gaskets can lead to rough idling, reduced power, and increased emissions.
• Timing Chain Failure: In some cases, the timing chain can stretch or break, causing catastrophic engine failure.

Transmission

5-Speed Automatic

• Torque Converter Shudder: Vibration or shuddering during acceleration can indicate a faulty torque converter.
• Shift Solenoid Failure: Malfunctioning shift solenoids can cause delayed or harsh shifting, slipping gears, and transmission overheating.
• Transmission Fluid Leaks: Worn or damaged seals or gaskets can lead to transmission fluid leaks, which can affect performance and cause damage to the transmission.

Suspension

• Air Suspension Compressor Failure: The air suspension compressor may fail, causing the vehicle to drop to the ground.
• Lower Control Arm Bushing Wear: Worn or torn lower control arm bushings can lead to a rattling or knocking sound when driving over bumps.
• Rear Shock Mount Corrosion: Corrosion of the rear shock mounts can affect ride comfort and handling.

Electrical

• Alternator Failure: A faulty alternator may not provide sufficient charging power, leading to battery discharge and engine starting issues.
• Wiring Harness Faults: Electrical problems, such as flickering lights or malfunctioning electronics, can be caused by wiring harness faults.
• Brake Light Switch Failure: A defective brake light switch may prevent the brake lights from illuminating, posing a safety hazard.

Exterior

• Sunroof Drain Plugs: Clogged sunroof drain plugs can cause water to accumulate and leak into the cabin.
• Rear Window Regulator Failure: The rear window regulator can fail, preventing the window from being raised or lowered.
• Mirror Cover Detachment: The mirror covers may detach from the mirrors due to weak adhesive.

Interior

• Climate Control Panel Malfunction: The climate control panel may become unresponsive or display incorrect information.
• Dashboard Rattles: Loose or poorly fitted components in the dashboard may produce rattling noises.
• Navigation System Lag: The navigation system may experience lag or freezing, affecting its functionality.

Summary:

The 2008 Mercedes-Benz E280 has experienced a range of issues that vary in severity and cost to fix. Some issues, such as cylinder head corrosion, can lead to major engine problems and expensive repairs.
