2016 Mercedes-Benz S550 4MATIC

I got this certified car from Mercedes Benz dealer. I have driven it sparingly for less than 10K miles without really any hitting any bumps or potholes . After a recent service [XXX] 2024 at a MB dealer, I was told that 2 wheels were cracked 1 front & 1 back . I took it to another MB dealer (MB Morristown, NJ) to change the wheels & they advised that all 4 wheels were cracked, & one wheel had 3 cracks. These are premium AMG staggered wheels & without a doubt there is genuine design issue or defect to wheels which at high-speed could crack & crumble causing major injury & destruction to property. I have all the service records regarding this issue INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2016 MERCEDES CLS550... I BOUGHT THIS CAR USED AND I'VE HAD IT FOR ABOUT 6 MONTHS. I'VE ALREADY HAD A SEIZURE IN THE CAR AND WAS FOUND SLUMPED OVER BY FLORIDA HIGHWAY PATROL AT A DEAD STOP WITH THE CAR RUNNING AND THE AIR ON AND I WOKE UP IN THE HOSPITAL. SOMETHING IS WRONG WITH THE AIR CONDITIONER CAUSING CARBON MONOXIDE POISONING IS THE ONLY THING THAT I CAN PUT TOGETHER. THE HOSPITAL OBVIOUSLY WOULD NOT THINK THAT IT WAS BECAUSE OF MY AIR CONDITIONER. THEY DID A CAT SCAN EVERYTHING FINE . THEY DID A COVID TEST EVERYTHING AND I WAS CLEARED AND OUT THE DOOR IN 5 HOURS. I HAVE PUT THIS TOGETHER AND FIGURED IT OUT MYSELF. I'VE HAD NOTHING BUT A FOUL SOUR DISGUSTING ODOR COMING THROUGH MY AIR CONDITIONER AND I HAVE ALMOST PASSED OUT ON THREE OTHER OCCASIONS SAME EXACT FEELING UP UNTIL I HAD MY SEIZURE. SOMETHING IS DEFINITELY WRONG AND I WENT AHEAD AND REPLACED MY CABIN FILTER. I STILL HAVE THE ONE THAT WAS IN THE CAR. I WANT COMPENSATION FOR THE DAMAGE THAT HAS BECOME OF MY BODY BECAUSE OF THIS CAR. I HEARD THAT THERE HAS BEEN MANY LAWSUITS FOR THE AIR CONDITIONER ON THIS MODEL AND OTHER MODELS BUT NEVER ANYTHING THAT WOULD KILL SOMEONE. I'M AFRAID TO DRIVE THE CAR. I'VE HAD A TESTER USED IN MY CAR AND IT PICKED UP CARBON MONOXIDE. I AM GOING TO SUE THE BALLS OFF OF MERCEDES AND THE DEALERSHIP THAT SOLD ME THE CAR FOR NOT FIXING THIS PROBLEM OR ANY RECALLS THAT WERE PUT OUT. ANYWAYS I CAN ALMOST SMELL THE EXHAUST FUMES ON TOP OF A SOUR SMELL. GOOD THING I'M SMART ENOUGH TO PUT TWO AND TWO TOGETHER. I EXPECT SOMEBODY TO GET BACK TO ME ASAP AS I WILL BE SEEKING LEGAL REPRESENTATION AND I WILL BRING THIS PUBLIC.

FROM 2014 THROUGH 2016 THE INTELLIGENT DRIVE AND THE DRIVER ASSISTANCE PACKAGE DOES NOT WORK. I KEEP SAYING THE S550 THINKS 200 FEET IS 90 FEET AND 100 FEET IS 30 FEET. WHAT I MEAN TO SAY IS THE SYSTEMS THINK 90 FEET DISTANCE IS 200 FEET AWAY AND 30 FEET IS 100 FEET AWAY. IT DOES NOT MEASURE THE DISTANCE PROPERLY. IT COULD BE, AND MOST LIKELY, A PROGRAMING ISSUE. IT IS THE SAME ON ALL THE 2014 THROUGH 2016 S550'S I HAVE TRIED. THE OTHER THING IT DOES WITH THE DISTRONIC CRUISE CONTROL IS WHEN IT STARTS TO BRAKE, THE DISTANCE SET DECREASES AND THE CAR SPEEDS UP AND AGAIN THE DISTANCE SET DECREASES AND THE CAR SPEEDS UP AND SO ON. IT CHANGES THE DISTANCE ( YOU CAN SEE IT HAPPEN IN THE IN THE MENU SETTING ON THE SPEED AND TACHOMETER SCREEN) AS SOON AS THE CAR AUTONOMOUSLY BRAKES. SET IT AT 200 FEET AND IN REALITY IT IS 90 FEET AND AS SOON AS IT BRAKES THE DISTANCE TO KEEP INSTANTLY DROPS TO JUST UNDER WHAT IT IS SET AT SO THE CAR THINKS THE DANGER IS OVER AND SPEEDS UP AGAIN AND THEN BRAKES AGAIN. AND YOU KEEP GETTING CLOSER AND CLOSER TO THE CAR IN FRONT BECAUSE THE SET DISTANCED KEEPS CHANGING AND YOU HAVE TO BRAKE SO YOU DO NOT HIT THE CAR IN FRONT BECAUSE THE S550 WON'T. I HOPE THIS MAKES SENSE. IT IS EASIER TO SHOW WITH THE DISTANCE GRAPHIC UP ON THE SCREEN. THE WHOLE SYSTEM IS COMPLETELY SCREWED UP. AS IS THE LED LIGHTING SYSTEM IN THE SNOW AND FREEZING RAIN AND SLUSH. CANNOT DRIVE IT AT NIGHT IN A WINTER STORM. IT ALL HAPPENS AROUND TOWN TO HIGHWAY SPEEDS. I WAS ACTUALLY TOLD BY THE SERVICE MANAGER FOR THE DISTRONIC CRUISE TO WORK I HAVE TO BE DRIVING FASTER THAN 75 MPH. MY 2007 S550 4 MATIC'S DISTRONIC AND AUTONOMOUS BRAKING WORKED PERFECTLY.

Complaint Repeat workshop visit for vehicle vibration while braking from 60MPH. NOTE: Although the symptom is similar to a tire or wheel vibration, it is usually readily noticeable that it is distinctly different if it happens at all times or only while braking. Cause Although the cause of the vibration is most likely due to excessive lateral runout on the rotor or hub/wheel bearing, the system as a whole needs to be checked for other possible contributors. 1. Prior collision damage. 2. Excessive vehicle sitting times without rotating components. 3. Wheel bearing/hub lateral runout. 4. Wheel mating interface has been overtightened (did not follow WIS torque procedures). 5. Mating interfaces have been excessively modified (painted, gouged, bent, etc...). Remedy Read through the entire attached worksheet prior to performing. After performing, please review the final page and perform work accordingly. NOTE: This document is not pre‑authorization or otherwise dealing with warranty. This is intended for diagnostic purposes only. If there are any questions on how to proceed OR The work sheet has been performed and the vehicle has returned with the same concern. Please perform the measurements as seen in the worksheet again and open a TIPS case to the Body, Chassis, and Entertainment team.

Complaint Clanking noise from the area of the speakers in the doors. Cause Under analysis. Remedy To narrow down the cause, first of all remove the door trim. • If the noise continues to occur even with the door trim removed, then continue the diagnosis working towards the speaker and if necessary, create a TIPS case with an informative video as an attachment. Note: Please refer to this document in the warranty claim and, once diagnosis is completed, select the damage code depending on the component part that is causing the issue. • If the noise stops when the door trim is removed, please proceed in accordance with LI72.10‑P‑067691. Information: In this case, do not use a damage code for the speakers in the warranty claim!

Complaint Only vehicles with a variable transfer case are affected. This can be identified through control unit N45 or N15/7 in the quick test. When accelerating with light load, vibrations or jolting sensation may come from the drivetrain. It may be mistaken for a harsh shift. Cause Modified oil quality of the transfer case over time Remedy 1. Check initial quick test for faults in the following control units. N45 or N15/7 ‑ All‑wheel drive (ARS) N127 ‑ 'Drivetrain' (PTCU) control unit Y3/8 ‑ Transmission control for 9‑gear transmission (VGS) N3/10 ‑ Engine electronics for combustion engine If faults are present: Process them as per the guided test in Xentry. If no faults are present: 2. Check the transmission oil level If the oil level is correct: 3. Unplug the connector for the transfer cases control unit and reassess the vehicle on a subsequent test drive If the complaint no longer occurs with the control unit disconnected: 4. Perform an oil change of the transfer case according to WIS specifications ‑ Collect an oil sample of the original fluid 5. Complete all transfer case Tech‑in processes located under VG Control Unit > Adaptations ‑ Resetting the oil service data ‑ Calibration of N15/7 5. Perform road test of vehicle to bring transmission to operating temperature (>60C ) 6. Operate vehicle in full circle with steering at full lock ‑ 5x to the left ‑ 5x to the right Return the vehicle to the client and request they drive the vehicle for at least 200 miles and return if the concern is not resolved. The extended drive will ensure the clutches are properly conditioned with the new oil and should resolve the concern. If this LI has already been applied to the vehicle, please submit a TIPS case to the Powertrain inbox with the following information: ‑ Initial quick test with fault freeze frame data ‑ Initial transmission EEPROM data ‑ VGS and Transfer Case Control Unit Log (N45 or N15/7) ‑ Special Acquisition Data .txt file (Transfer Case Control Unit > Special Procedures > Procedures for support queries to market support > Special Data Acquisition) ‑ Photo of the original oil condition ‑ What color was the fluid drained from the transfer case before the oil change? ‑ Was an oil sample collected, and can you provide a photo of the original fluid? ‑ What color and part number fluid was used during the oil change? ‑ How far was the vehicle driven after?

Complaint During part of the steering movement, it feels heavier or more difficult to steer in the same spot every time. OR Rattling, humming, dry sliding/gravel noise from the electric steering system when steering (see attachment). Complaint does not impact the ability to safely steer or control the vehicle. Cause Ball screw drive (KGT) of electric steering damaged by: 1. External force due to: ‑ Hitting the curb/posts with the front wheels. ‑ Driving over obstacles (e.g. pothole/ threshold/ speed bump/ gully) at an inappropriate speed. 2. Corrosion/ water ingress through a damaged boot (see attachment). ‑ Cracks (1) ‑ High pressure cleaner (2) ‑ Animal bite (3) See various examples listed in the attachments for examples of outside influence. Remedy Remove boot clamps closest to steering gear housing on both left and right (as seen in "Steering Rack Boot Clamp Location"). Pull back boot and inspect for rust, broken end stops, water, or any other anomalies. Replace electric steering. Note: Steering gears replaced due to outside influence or damage must not be claimed under warranty!
