Mercedes-Benz 300SE Problems

Transmission Oil Seals May Leak on High Mileage Vehicles

Drive Train -- Verified

High mileage vehicles may develop a transmission fluid leak from one or more of the oil seals.
 

Power Window May Fail Due to Window Regulator

Miscellaneous -- Verified

One or more door windows may stop working due to a failed window regulator. Replacement of the failed regulator will be necessary to correct this concern.

The Differential May Develop Leaks From the Seals or Cover

Drive Train -- Verified

Leaks may develop from the differential seals and/or cover on older or high mileage vehicles. Our technicians recommend a complete reseal of the differential unit when these leaks are addressed.

Squeaking/Worn Brake Pads May Require Rotor Replacement Also

Brakes -- Verified

The brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors.  The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).

ABS Modulator Failure Due to Dirty Brake Fluid

Brakes -- Verified

As brake fluid becomes dirty over time, it can cause a failure of the anti-lock brake system (ABS) modulator assembly. Our technicians recommend a complete brake system flush every two years to help prevent this issue.

Mr. Benz, 1990 Mercedes-Benz 300SE, Atlanta, GA

The driver's seat moves forward and the back of the seat reclines when the vehicle is started. It occurs about half of the time I start the vehicle. What could be the cause of this malfunctioning?

Mercedes-Benz 300SE Stories

the design is truly classic.Beautifully solid and quality car.

One of the best Mercedes ever made. This is my third Mercedes, the 1990 300 SE, and I am about to spent $4000 to get a paint job. Car runs great and I have only 160000 miles. The design is truly classic.
Elegant lines going to a great front end. Can't wait to see it like new and drive it for the next twenty years.

Beautifully solid and quality car. Every line on its body has purpose, nothing is clumsy or mediocre. Nice extras like all the little map lights, leather everywhere, everything that is wonderful about this car makes up for the things that take alittle extra money or time to maintain.
A well maintained 300SE will last a million miles, a neglected one will be a money pit. Make sure you buy one that wasnt mistreated.
This car has one of the best transmissions ever made.
Hundreds of safety features, windows roll down if car is submerged. They will never build this kind of quality again.

i love this type of cars its solid and relaiable

This is my first S-class Benz I love this car.
It is 16 yrs old and does need some minor repairs,which aren`t to expensive.I just sometimes have to sacrifice some thing,sometime to pay for them.
I would rather push an old Benz than drive a new Ford.
