2019 Mercedes-Benz AMG GLC43

On January 8, 2021, after ongoing review with Mercedes Benz, the National Highway Traffic Safety Administration (NHTSA) Office of Defects Investigation (ODI) opened PE21-001 to assess allegations of front roof panel detachments while driving at highway speeds in certain 2015 Mercedes-Benz (Mercedes) C-Class vehicles.The subject front roof panel is a stationary panel composed of polycarbonate and is attached to the vehicle via adhesive at the time of manufacture. The panel is found on subject vehicles equipped with panoramic sunroofs. Over time, the subject panels may exhibit cosmetic degradation leading to replacement of the panel, a procedure which entails: removal of the old panel and adhesive, site preparation, and installation of a replacement panel with new adhesive.The consumer complaints that prompted the opening of PE21-001 all described detachments of front roof panels that had been replaced after the vehicle was put into service.Mercedes' internal investigation identified a broader scope of affected vehicles (2014-2020 CLA, GLA, C, S, GLC, and GLE class) and found the following potential service procedure- related causes of front roof panel detachments:- Improper surface pretreatments such as the use of the wrong primer or cleaner or scoring of the surface; or - Use of the incorrect adhesive.These conditions lead to a front roof panel bond that, even if sound at the time of repair, cannot maintain its strength over time and environmental exposure.Mercedes updated its service and parts ordering systems to reinforce the proper use of specified kits and procedures via webinars, shop foreman meetings, and explicit reference to the risks incurred by diverging from the repair procedures. Mercedes is also furnishing parts ordering assistance, and will hold dealerships accountable for improper repairs.ODI's analysis of the ten complaints it has received from the public (VOQ's) and MBUSA's complaint data submitted in response to the information request letter for PE21-001 identified a total of 57 non-duplicative reports alleging incidents in which the front roof panel detached from the vehicle while in motion. Included within the 57 reports are incidents where consumers state the panel detached ...and flew off into traffic.On March 19, 2021, Mercedes notified NHTSA that it would recall subject vehicles with front roof panels known to have been replaced after the original sale of the vehicle. In total, the recall (designated as Recall 21V197) covers 15,099 vehicles that were ever registered in the United States. Based on Recall 21V197 and the remedy implemented by Mercedes, further investigation does not appear to be warranted at this time.Accordingly, this investigation is closed.The ODI complaints cited above can be viewed at www.nhtsa.gov under the following ODI identification numbers: 11376425, 11352686, 11351629, 11349158, 11341541, 11337594, 11324100, 11311591, 11222127, 11404183

The suspension has malfunctioned on a car with only 89,000 miles. Upon starting the car, the vehicle says to please wait while it is rising. However, when I drive it, a red alert says to stop driving because it's too low to drive, and the car looks very low and lopsided. This is a safety concern when driving on the highway and around town. This appears to be an issue on other Mercedes models, such as the 2020 model; please consider 2019 as a year of concern as well.

Whenever I turn my wheels at an angle, there’s a juddering and knocking sound. It feels as if the axle will eventually break. This can pose a safety concern.

A FEW TIMES MY KEY WILL NOT FUNCTION TO START THE CAR. THEY TOLD ME IT WAS THE BATTERY. BUT THE DISPLAY ON MY LCD ALSO OFTEN DOES NOT FUNCTION WHEN ON CAR PLAY. THE STEERING IS JERKED WHEN I TURN THE WHEELS AS THEY SEEM TO GET STUCK ON THE PAVEMENT. OFTEN HAPPENS WHEN I AM BACKING OUT OF A PARKING SPACE AND SOUNDS AS IF I AM HITTING SOMEONE. FEELS LIKE IT TOO

I PURCHASED A 2019 GLC AMG 43 AS A XMAS GIFT FOR MY WIFE. IT WAS BLACK WITH A VIBRANT BROWN INTERIOR. I WAS CONCERNED THAT THE ELECTRONICS(BACKUP CAMERA, BLUETOOTH, MUSIC, ENTERTAINMENT CONSOLE) WERE NONFUNCTIONAL. HOWEVER, THE EXPLANATION THE SALES REPRESENTATIVE GAVE ME WAS SUFFICIENT AT THE TIME. HE SAID MERCEDES WAS UPDATING THEIR COMPUTER SOFTWARE AND WE SHOULD BE GETTING AN UPDATE ON JANUARY 2, 2019. NEEDLESS TO SAY, IT WAS NOT TRUE! THE SERVICE MANAGER EXPLAINED THAT THIS VEHICLE WAS MISSING THE "BRAIN." THE COMPUTER SYSTEM THAT COMMUNICATES WITH THE ENTIRE VEHICLE WAS NOT IN OUR VEHICLE?YES! WE WERE SOLD A VEHICLE THAT WAS NOT READY FOR PRODUCTION. IT'S UNSAFE, AND RATHER THAN BEING OFFERED ANOTHER COMPARABLE VEHICLE FOR BEING SO NEGLIGENT AND INCONVENIENCING ME AND FAMILY, THE GENERAL MANAGER HAS AVOIDED SPEAKING WITH US ALL TOGETHER. I HAVE BEEN COMMUNICATING WITH MERCEDES USA TO RESOLVE THIS ISSUE. AT ONE POINT OF THE TRANSACTION WE WERE ASKED TO POSSIBLY CONSIDER TAKING THE REFURBISHED VEHICLE BACK AFTER ITS REPAIRS. NONE OF THESE GUYS MAKING THE RECOMMENDATION WOULD TAKE A VEHICLE THAT THEY BOUGHT BRAND NEW AFTER IT HAS HAD MAJOR SAFETY AND ELECTRICAL ISSUES. THIS IS MERCEDES LONG BEACH SICK IDEA OF WORLD CLASS SERVICE! TO ADD SALT TO THE WOUND, IT'S NOW BEEN OVER 3 WEEKS AND WE MUST MAKE A CAR PAYMENT ON A VEHICLE THAT SITS IDLE WAITING FOR MISSING COMPONENTS. UNFORTUNATELY, WE ARE STILL WAITING FOR MERCEDES TO DO THE RIGHT THING. THIS WILL BE THE LAST MERCEDES MY FAMILY AND I WILL PURCHASE

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.

Dear Mercedes-Benz Owner: In our continuing efforts to ensure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA is extending the warranty coverage for the Diagnostic Module for Tank Leakage Detection ("DMTL") on your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 15 years/150,000 miles (whichever occurs first).
