I STOPPED FOR A RED LIGHT, I SAW A POP UP ON THE DASHBOARD THAT READ 'BRAKE ASSIST DISENGAGED'. AT THAT POINT THE CAR SHUT ITSELF OFF. I TRIED TO RESTART WITH NO SUCCESS, IT WOULDN'T EVEN TRY TO TURN OVER. AFTER SITTING IN TRAFFIC FOR ABOUT THREE MINUTES UNABLE TO RESTART THE CAR, I JUST KEPT HITTING THE START / STOP BUTTON AND IT FINALLY TURNED OVER AND STARTED. I REPORTED THIS INCIDENT TO THE DEALERSHIP AND WAS TOLD THEY WOULD WORK ON THE CAR IF IT HAPPENED AGAIN! IF IT HAPPENS AGAIN IT COULD RESULT IN A MUCH WORSE OUTCOME. I WAS DEAD IN TOWN TRAFFIC, HEADING STRAIGHT THRU A RED LIGHT AFTER A COMPLETE STOP.

I WAS JUST DRIVING HOME ON A CITY STREET (9/20/18) AT ABOUT 35 MPH WHEN UNEXPECTEDLY THE BRAKES ON MY E43 LOCKED UP LAUNCHING MYSELF AND MY PASSENGER FORWARD AGAINST OUR SEAT BELTS. THE ANTI-LOCK BRAKES ENGAGED; I HEARD THE REAR TIRES "CHATTER". THE CAR DID NOT COME TO A COMPLETE STOP; THE BRAKES DISENGAGED AND WE ROLLED FORWARD. UNTIL I REALIZED WHAT HAPPENED I THOUGH I HIT SOMETHING. THERE WAS NO ONE IN FRONT OF ME, BUT THERE WAS SOMEONE BEHIND AND BESIDE ME. I TOOK THE CAR INTO MERCEDES AND THEY UPDATED THE SOFTWARE AND CHECKED THE SENSORS AND REPORTED BACK THAT EVERYTHING IS WORKING PROPERLY. SINCE THEY DID NOT FIND ANYTHING SPECIFIC - I FEEL THAT THE CAR HAS A DEFECT THAT IS DANGEROUS TO THE PUBLIC AND SHOULD BE RECALLED UNTIL A SOLUTION CAN BE DEMONSTRATED. THE PUBLIC NEEDS TO KNOW ABOUT THIS. OTHERS HAVE REPORTED THIS EXACT OCCURENCE. THIS IS A DEFECT THAT WILL RESULT IN SERIOUS INJURY - OR WORSE. THE CAR HAS PREMIUM PACKAGE 3 WHICH INCLUDES THE ACTIVE BRAKE ASSIST PROGRAM. I SUSPECT THIS WAS THE PROBLEM. ANOTHER PERSON REPORTED THIS WHEN CROSSING ONTO A BRIDGE. THAT WAS MY SPECIFIC EVENT ALSO; THE CAR DIPPED SLIGHTLY AS I WENT FROM STREET PAVEMEN TO BRIDGE PAVEMENT. PLEASE COMPEL MERCEDES TO TAKE RESPONSIBLE ACTION AND TAKE STEPS NECESSARY TO PROTECT THE PUBLIC; REGARDLESS OF HOW RARE THE EVENT MAY BE.

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!

Complaint Tailgate opens unintentionally. Cause Accidental or unnoticed activation of the button to open the tailgate on the vehicle key. EXAMPLE: when stored in trouser pocket, handbag etc. Remedy As of the 6th generation, the vehicle key can be recoded so that the tailgate no longer opens as a result of a long press on the button, but by double‑clicking on the button instead. This reduces the likelihood of the button being activated accidentally or unintentionally. The recoding can be carried out as follows: 1. Add SA Code O19 into VeDoc (O for Oscar, not "zero") • an XSS ticket may be necessary to add the SA code 2. Perform SCN coding of EIS N73 control unit 3. Deactivate the vehicle key (a successful deactivation is indicated by the LED lighting up 2x briefly and then 1x for a long period). 4. Place the vehicle key in the storage compartment on the key symbol and turn on the ignition. IMPORTANT: all other vehicle keys must be outside the recognition range of the vehicle when doing this! Perform steps 3 and 4 successively for all vehicle keys. Notes: 6th, 7th and 8th generation keys can be deactivated as follows: Up to modification year 22/1 by double clicking the "Lock button" As of modification year 22/1, by press and holding the “Lock button", then double‑click the “Unlock button" at the same time. On model series 167, the storage compartment with the key symbol is located in the armrest. The SCN coding from the EZS is only transferred correctly to the vehicle key under the following conditions: Only one vehicle key is located in the vehicle, this key has been deactivated and it is positioned on the marking in the storage compartment for the data transfer. The costs for this adaptation are to be borne by the customer. For the newer BR 174, 178, 244, 248, 520, and 540, a software update must be initiated, as there is no way to perform SCN coding.

Complaint A popup is seen on the HU with the message "data connection temporarily not available". Potentially affected functionalities in NTG4.5, NTG5 1.Weather 2.Local Search 3.IP Radio 4.Send2Car 5.Speech Detection Service 6.Navigation 7.iHeartRadio 8.Traffic Cams Cause MB Apps is sundowned for all vehicles with NTG4.5 and NTG5 Head Unit Variant. Remedy No support available for NTG4.5 and NTG5 Head Unit Variants for MB App related topics. Note: Please do not create TIPS. Please do not replace any components. HU/Hermes SW update / SCN coding will not fix the issue.

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. Information: Please refer to this document in the warranty claim and, after completing diagnosis, select the damage code corresponding to the component part that caused the problem. • 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 This document is intended as a pre-case diagnostic reference for transmission related concerns. It will also ensure that if a case is necessary, all supporting documentation is available. This should not be used on its own as justification for creating a TIPS case. Cause The root cause will vary depending on the complaint. The goal of this document is to provide diagnostic checks and procedures that may help resolve customer complaints without opening a TIPS case. Remedy Before opening a transmission-related TIPS case, the following steps must be performed to ensure all relevant data has been collected and possible remedies (when applicable) have been performed. Please Note: At minimum, the documents below must be collected before proceeding to ensure the data in its original state when the vehicle arrived is captured. - Initial Quick Test w/ Freeze frame data - VGS Control Unit Log - Initial EEPROM data (.txt format) - IPR Result (if applicable. See LI27.00-P-073124 - Transmission diagnosis using the Intelligent Predictive Repair (IPR) tool) - Transmission Heath Page If the vehicle has previously been repaired for the same concern, note the date, mileage, and TIPS case or RO number, along with a brief description of the prior work performed. IPR Guidance: The IPR recommended repair should be completed prior to following any steps in this LI and prior to case creation. IPR repairs do not require additional warranty approvals or a TIPS case to validate/confirm the results. To ensure efficient case handling, please avoid opening TIPS cases for this reason. For further information regarding IPR please see the following documents: LI27.00-P-073124 - Transmission diagnosis using the Intelligent Predictive Repair (IPR) tool Oil Pan Condition Evaluation: In some situations, IPR will advise checking the oil pan condition and determining a repair based on the evaluation. Example photos in Xentry can be found in two ways: • Use the blue hyperlink in the IPR result, and it will take you to the Condition check of transmission oil • Navigate to Xentry Bluebook > Help for control unit > Condition check of transmission oil If a different repair that what is recommended by IPR is performed, attaching photo documentation of the complaint vehicle oil pan and the IPR example to the claim is required. Reproducing the Concern: Proper evaluation of transmission concerns generally requires the condition to be reproducible. It is recommended to compare the vehicle to a similar model, if available, to help determine whether the shift behavior is characteristic of the drivetrain or uncharacteristic for the vehicle. If the concern cannot be duplicated: • A test drive with the customer may assist in understanding and reproducing the complaint. • The vehicle shift quality should be compared to a known-good vehicle with identical drivetrain and model year. • Check Shift Quality History (VGS Control Unit > Adaptations > Shift Quality History) Shift Quality History will show the last 5 noticeable harsh shifts and some of the parameters in which it occurred. You can use this to attempt recreation of the operating conditions and increase likelihood of reproducing the complaint. Complaint A: Shift Quality Note: Certain AMG variants may exhibit more firm and noticeable shift behavior as a normal characteristic. Refer to LI27.60‑P‑075147 for additional information. 1. Perform Valve flushing procedure 2. Perform 5 Torque Converter adaptions in a row - Allow the vehicle to warm up naturally, DO NOT power brake as it will increase the temperature in the torque converter. - After the 5th adaptation, collect a screen shot showing all 5 on one page 3. Perform a standstill adaption - collect a screen shot Recheck vehicle operation. If the concern has not improved, driving adaptations should be performed to target specific gear shifts.

Complaint Mercedes-Benz USA is currently experiencing limited availability of transmission fluid specification ATF 236.17 due to a global supply constraint. 236.17 ATF 1L and 5L (PNs: A002989060312 and A002989060313) bottles are out of stock or in limited supply at Zep.
