About Mercedes-Benz S420
The first-generation Mercedes-Benz S420 was produced from 1994 to 1998 when the S-Class was in its third generation. It was offered in two body styles, 4-door sedan (W140) and 2-door coupe (C140) and came in only one trim level. During this generation, S420 was powered by a 4.2 L V8 rated at 275 horsepower and 295 lb-ft of torque and power was sent through a 5-speed 5G-Tronic automatic transmission to the rear wheels. The more recent S420 (W220) was introduced in July 1998 for the 1999 model year. It offered more interior space than the predecessor and brought many innovations in. Back then, S420 was equipped with Airmatic air suspension, Active Ventilated Seats (which used miniature fans in the seats to move air through perforations), a navigation system with center console-mounted screen display, the COMAND input control system, keyless entry and ignition, a radar-controlled Distronic cruise control system, a cylinder shut-off system called Active Cylinder Control and others. At that time, S420 still got power from the 4.2 L V8.
Mercedes-Benz S420 Common Problems & Maintenance Tips
First, poor idle quality is what Mercedes-Benz S420 drivers complain most about their driving. This is obviously an engine problem if you know something about the working principles of the automobiles. Because the working condition of the engine decides the vehicle performance, you had better get it solved as soon as possible since experienced S420 drivers also complained about the cooling system failure, which often deteriorates the engine failure. Normally, when coolants leak and the engine keeps overheating, you need to keep alert. Soon, you will notice the engine running roughly, misfiring, stalling and even suffering from starting issues such as hard starting or inability to start. In case your vehicle breaks down since now, you need to inspect the S420 water pump, intake manifold gasket, fuel pump, coolant reservoir, cooling hose, oil filter, air filter, engine control module and valve cover gasket immediately once the Low Coolant Light and Check Engine Light come on.
Second, another common and horrible problem on Mercedes-Benz S420 is the suspension failure according to the car repair statistics site repairpal.com. This problem is not more than a culprit of an uncomfortable and unsteady ride like most S420 drivers thought, under certain circumstance, you could lead to fatal accidents. When the clunking or grinding noises coming from underneath the vehicle try to distract your driving attention, you need to know you are in trouble. In the end, you will find hard to control the vehicle due to intense car vibration, tilting vehicle caused by uneven and excessive tire wear, unintentional steering and poorly operated steering wheel. All these symptoms could be attributed to the S420 shock absorber, wheel bearing, sway bar bushing, control arm bushing, coil springs, air suspension and coil spring insulator.
Never underestimate the role of routine maintenance on vulnerable auto parts of Mercedes-Benz S420 since preventative measures are always more effective than reactive ones. Parts such as S420 seat belt, windshield wiper, wiper blade, antenna, cabin air filter, fog light and headlight need to be maintained routinely as they play important roles in creating a safe and comfortable driving environment under harsh working conditions.
