Mercedes-Benz 600SEL Problems
Coolant Leak/Overheating Due to Radiator Leak
A coolant leak may develop form the Radiator due to degradation of its plastic components. Replacement of the failed radiator will be necessary.
Erratic Engine Operation and Poor Fuel Economy Due to Faulty Mass Air Flow Sensor
A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.
Coolant Hoses May Fail Unexpectedly
The cooling system hoses may fail unexpectedly. The hoses can look good on the outside, but the rubber can degrade and erode on the inside. If not carefully checked, the hoses can burst at any time.
Squeaking/Worn Brake Pads May Require Rotor Replacement Also
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
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.

Mercedes-Benz 600SEL Stories
Mercedes = junk. The worst car I have ever seen. I can't believe someone actually paid 160000 for this piece of crap. I am going to chop and sell parts. The main engine harness killed the car. I think Mercedes should get out of the car industry. Mercedes Benz died when the W126 life cycle ended. Hello Lexus.
Very unique car but buyer beware- it's an expensive car to maintain. If you're on a budget and not looking to have a close relationship with your friendly mechanic, this is not the car for you. Major problems include evaporator ( $3,000.00 +) and wiring harness issues ( $5,000.00+). Every 600 made before '95 will have to have the wiring harness replaced since Mercedes used a biodegradable coating for the wiring-eventually exposing the wires causing major,MAJOR problems. You have to have "deep pockets" to keep this car on the road and there are no cheap short cuts to take!
Never had a aproblem
nice car
