Mercedes-Benz 300E Problems
Interior Wood Trim Cracks Due to Age and Sun Exposure
Due to age and sun exposure, the interior wood trim cracks and the finish gets a cloudy haze. Replacement if the trim would be the most common solution to the problem.
Check Belt Tensioner When Replacing Water Pump
A coolant leak may develop from the water pump. When replacing the water pump, the drive belt tensioner should be inspected and most likely replaced as well.
High Usage Vehicles May Experience Ignition Lock and Tumbler Failures
Due to wear, high usage vehicles can experience ignition lock and tumbler failures. The ignition lock cylinder will generally require replacement to correct this concern.
Sunroof Components May Fail Due to Age and Wear
The sunroof may not work correctly due to failed components as a result of age and wear. Repairing a sunroof can be labor intensive and very costly.
Rough Running Engine Due to Misfire
A rough running motor or lack of power can be caused by a failed distributor cap or rotor, ignition wires (or their resistors), or valve cover gasket leaks. If the valve cover gasket leaks, oil can pool where the ignition wire resistor connects to the spark plug. The resistor can fail and the spark plug may not fire because of a short circuit through the oil.

Mercedes-Benz 300E Reviews
I have this Mercedes-Benz 1990 3000E all of sudden out of no were, the car was on park went to put in reverse the park car would not move! Had no signs of tranny problems at all! No leaks at all! car runs awesome until this! mileage is 168000! What could this be?
I've had my 92' 300E with the 3 liter engine for close to 15 years now and it now has 248,000 miles on it. I’ve only had the standard repairs to perform for a car of this age (radiator, alternator, belts) all self repaired/replaced. The only small annoyance is the need to add oil, about 2 quarts/month, but I've accepted it. The car still runs strong and rides well. It’s getting close to time for a replacement but it’s a tough car to replace what with its proven reliability through all the years. I'm looking at another E Class, just a bit newer. Mercedes did a good job with this class
Car is very dependable when it's running. Strong engine at 170K miles, but I do find that it has a problem with the air conditioner sometimes blowing and sometimes not. It happens quite frequently. I also have noticed that it leaks transmission fluid if it sits for more than a week or so. Those are the two problems that I have encountered with this vehicle at this juncture. I love the way it handles and its heavy enough to handle the road very well. I would buy another one with less miles if it came available.
