Mercedes-Benz ML55 AMG Problems

Brakes Pad life varies and is dependent upon driving style and terrain. One common problem our technicians report is that motorists will drive with the parking brake applied; this burns up the parking brake lining and wears out the brake rotors.
Engine
  • Oil leaks from the PCV vent housings on the valve covers and inspection plates on the front of the engine are common.
  • Motor mounts fail, causing engine vibrations to transfer to the body. The motor mounts should be replaced or the transmission mount may fail.
  • The rubber bond in the harmonic balancer can decay, which can allow the balancer to move and work its way into the timing chain cover.  If the harmonic balancer contacts the timing cover while the engine is running, it will fracture and damage the timing case and potentially other surrounding parts.  The harmonic balancer should be inspected at every service.
  • Oil leaks from the oil level sensor are common.
  • The crankshaft position sensors tend to fail.
Exhaust & Emissions
  • The welds tend to crack on the front catalytic converter. Replacement of the catalyst is required; re-welding of the catalyst is discouraged because it is an emissions device.
  • The mass air flow (MAF) sensor tends to fail. The engine air filter should be replaced when the mass air flow sensor is replaced; a dirty filter can allow debris to damage the new sensor.
  • As the spark plug wires age and are exposed to heat cycling, they start to develop micro cracks in the insulation around the resistors, which causes misfires and poor fuel economy.
Suspension & Steering
  • These vehicles have torsion bar-type springs for the front suspension. If the vehicle appears to be lower on one side (in front), the hard plastic insulator for the torsion bar may have cracked and split. There may also be a squeaking noise (when driving over bumps) from below the front seats if this insulator has broken.
  • The power steering return hose leaks at the radiator cooler fitting. If the clamp is not properly tightened, the hose can blow off, causing high steering effort and a mess under the hood.
  • The power steering rack develops fluid leaks.
Drive Train
  • High mileage or older vehicles develop leaks at the differential seals and cover; the whole unit needs to be resealed to repair the leaks.
  • The wire connector on the transmission leaks fluid into the wiring harness. If not repaired, the oil will migrate through the wiring harness and damage the transmission control module. A new harness and control module are required to fix the problem.
  • Due to slipping clutches in the transfer case, a shudder or rumbling from the center of the vehicle may occur, especially when turning at slow speeds. If the clutches are not too badly worn, changing the fluid will fix this problem. Otherwise, the transfer case will need to be disassembled to change the clutches.
Electrical & Lights
  • Brake light switch failure can cause the ESP and BAS warnings to illuminate.
  • The power window switches tend to fail and the windows will not raise. The main switch at the front center console should be replaced.
  • Drive authorization fails to recognize the keys, causing a "no start" condition. A new module and keys will be needed.
  • The "all activity module" can cause multiple electrical malfunctions.
Heating & Air Conditioning
  • The heater blower motor can become abnormally noisy.
  • AC system leaks and bad evaporator temperature sensors can cause poor AC cooling. The bad sensors can prevent the AC compressor from coming on and leaks cause a low refrigerant level, which lowers the ability to cool.
