Mercedes-Benz S550 Problems

Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

Brake Pads & Rotors May Wear After 20,000 Miles

As a way to increase braking performance, the brake pads and rotors are make of a softer material and may be in need of replacement after approximately 20,000 miles; owners should be vigilant about getting their brakes checked.

Mercedes-Benz S550 Recalls

Front Seatbelt Anchor

These vehicles are being recalled because the front seat belt anchors may not be installed correctly and can come loose in a crash, increasing the risk of personal injury. Dealers will inspect the affected front seat belt anchors and perform the necessary correction.

Potential Fuel Leak

Due to a manufacturing defect, a crack can develop on the fuel filter when the vehicle is operated in high temperatures. This crack can result in a fuel leak, increasing the risk of a fire. Dealers will replace the fuel filter to correct this concern.

Tire Pressure Monitoring System Malfunctions

The tire pressure monitoring system warning light may not come on or stay on for appropriate lengths of time. Dealers will reprogram the tire pressure monitoring unit free of charge to resolve the concern.

At 40,000 had to replace front rotors and brake pads. Very happy with cars performance but replacing tires every 10,000 miles and having to replace brakes at 40,000 is upsetting.
I paid almost 7K to add the monitors in the rear along with all the extras. I was told by the dealer I could use the screens for my laptop while using the built in WiFi in the car for internet. Turns out the internet is only 3G and HORRIBLY slow to the point I can barely send an email. The monitor connection is standard video only! Composite Video!! No HDMI or even VGA.

My first Mercedes. a 2012 S550. cars pulls bad to the right. Thought is would be a tire or alignment problem. Was told they all did that, and there was no adjustment to correct it.
