2003 Mercedes-Benz S600 Problems

Suspension & Steering -- Verified

The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

Engine -- Verified

Engine misfires (rough running) and lack of power are commonly caused by ignition coil pack or ignition module faults. Proper diagnoses should isolate the cause and prevent unnecessary replacement of good parts.

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).

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.

Miscellaneous -- Verified

The door for the vanity mirror (or the frame for the door) can break; due to a redesign, the mirror "cassette" will need replacement.

2003 Mercedes-Benz S600 Reviews

I bought my 2000 S500 used about 2 years ago. It had on the clock then 115000 miles, now 160k. So far in cost, $35.00 dollars for a crank sensor. I know at least 15 to 20 other folks that have these and they report not a problem out the norm. One person has over 190k an still going strong. Yes I do agree, to have bought one of these brand new, I would not spend that kind of money. Here's a suggestion(s) if someone out there is looking to get one of these vehicles. Make SURE to get the CARFAX on it. If the vehicle has been checked regularly, recalls taken care of, you should be fine. DON'T go buy a extended warranty. First fine 2 to 3 RELIABLE foreign mechanics that know these vehicles inside out. I have 4 just in case. Oil changes every 5000 Mobil 1. You can push it to 7500, but try to stick to 5000. And lastly. If you do have issues with your car, buy the parts ONLINE!!! DO NOT GO TO MERCEDES!! There mark up is ungodly. If you take care of any car, it will last forever. If you don't stay on top of ANY luxury car and don't have money to fix it when things go wrong, it's not the car, it's you.

It's hard to believe how difficult this car has been to deal with -- Mercedes should be embarrassed. Even my mechanic has empathy for me as this car has been a lemon from day one. On the upside, it is absolutely gorgeous. It is in the shop every month for the past two years. Luckily, I have an aftermarket warranty. Most problematic areas: 1) ABS/suspension 2) center console cup holder (design flaw -- i've gone through 4) trunk motor 5) seat systems, etc.
