2023 Mercedes-Benz S 580

The tire (Pirelli 255/35R21) on my 2023 Mercedes Benz 580V4 developed a bubble on its sidewall. This tire was just replaced February 16, 2024, and has under 8,000 miles on it. This is the fourth tire I have replaced due to bubbles on the sidewalls.

On [XXX] I had a blowout on the passenger front side of my vehicle. The vehicle was towed to Sugarland MB and a new Pirelli 255/35 R21 purchased. The blowout happened after I hit a bump (not pothole) in the road on [XXX] at [XXX] . My 2023 MB 580V had 9701 miles on it and had just had it's first "A" service with no defects noted in any of the tires. On [XXX] I noticed a bulge on the front driver's side tire. I took it into Sewell MB and they notice additional defects on another tire. I had to purchase one front driver side 255/35 R21 and a rear passenger side 285/30R 21. After leaving the dealership I filed a complaint with the NHTSA file #11622692 and called Pirelli to report the failures and make a formal complaint. I also called MB customer service and opened case #[XXX]. A representative from Pirelli contacted me on 10/31/2024 @ 11:00am and basically stated the issue with multiple failures of these 21" tires across the US is a MB problem and not Pirelli's. As of this followup complaint I have not been contacted by any one else . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I had 9985 miles on my 2023 Mercedes S580V when the front passenger tire experienced a blowout earlier this year. The tire failed right after I had my first A service which did not show an issue with tires. Today is 10/30/2024 and I have 13978 miles on my vehicle. The driver side front tire Pirelli 255/35-R21/98Y has a bubble on the side wall. I took it to my dealership and they discovered that the rear passenger side Pirelli 285/30-R21/100Y has a bubble as well. I am having both tires replaced today.

The "distronic" cruise control is so abrupt in its acceleration and declaration that vehicles behind me tend to take evasive action. The car doesn't sense vehicles far enough ahead to take smooth action, resulting in a jarring, favorite, and fearful ride.

When in eco mode the vehicle will occasionally shut off at a stop light. The vehicle "jumps" and then all of the warning signals come on followed by the vehicle shutting down. It takes about 20-30 seconds for vehicle to be able to restart again. The dealership had the vehicle for nearly a month and the only solution they came up with was to turn eco mode off every time I start the vehicle. They said their will be a future recall to fix this issue. Also, the vehicle will occasionally move forward on its own and then quickly break. This phantom braking is quite painful and feels as if you were just hit from behind. A previous problem was the vehicle would move forward after being taken out of car wash mode even with the brake engaged. The dealership said this was solved by a software download. There is a current recall which includes the make and model of this vehicle but Mercedes insists this vehicle is not included in the recall. The vehicle was manufactured within the time frame listed in the documentation from NHTSA but nonetheless Mercedes does not include this vehicle amongst the cars qualifying for replacing the fuel pump. I believe this car is dangerous and will hurt somebody.

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 Traffic sign symbol for "Traffic Sign Assist" is blinking in instrument cluster without obvious cause usually with one of the following scenarios: • Flashing without a speed limit ("‑ ‑"). • Flashing when current vehicle speed is under speed limit. • Flashing between US speed limit symbol and European speed limit symbol. NOTE: • Verify that the concern falls under one of the attachment videos. If not, then it is outside of the scope of this LI. • This also does not cover "Traffic Sign Inoperative" messages on the instrument cluster. Cause There are two identified reasons for this concern: 1. Country code information stored incorrectly at a particular geographic latitude range. 2. Incorrect reference data when the vehicle is started and a GPS signal is not immediately available. Remedy Update head unit software to latest version and the re‑check function in the same location. If vehicle is still exhibiting one of the symptoms as described exactly as in the complaint section or as shown in the video attachments, open a TIPS case to the Body/Chassis/Entertainment inbox with the following: • Video of the concern. • Exact location (latitude and longitude is best)

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).
