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.

This NCU replaces the prior NCU issued on May 15, 2025, and contains additional MY 2023 and MY 2024 vehicles which are highlighted below. In our continuing efforts to ensure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA, LLC (“MBUSA”) is extending the warranty coverage on the Diagnostic Module for Tank Leakage detection (DMTL) in certain Model Year (“MY”) vehicles listed below from the original New Vehicle Limited Warranty of 4 years/50,000 miles to 10 years/120,000 miles (vehicles certified as LEV II) and 15 years/150,000 miles (vehicles certified as LEV III), whichever occurs first, for the following condition: •Under certain circumstances, the DMTL may trigger erroneous Diagnostic Trouble Code (DTC) entries that may result in the illumination of the Check Engine Malfunction Indicator Lamp (‘MIL’).

Complaint Check Engine Light ON with DTC P012800 "The Coolant Temperature is Below the Specified Temperature" active and/or stored in the ME (N3/10). There are no drivability concerns related to this complaint. Cause Root cause varies Remedy Prior to performing any repairs for this complaint: With a cold engine, pressurize the high temp coolant circuit and while it's under pressure, release the cap on the low temp coolant circuit and check if the pressure drops right away or not. If the pressure drops, the lower coolant hoses are swapped. Correct this, fill, bleed and test drive the vehicle. If the complaint returns, then continue with the steps below. IMPORTANT: Use VMI to check for the following emission extended warranty –> Engine Thermostat (incl. software update) MY19-23, Various Models and Platforms (167, 190, 205, 213, 217, 222, 223, 232, 253, 290, 463) If the vehicle is covered under the above emission extended warranty, please perform steps outlined in the accompanying NCU prior to those outlined in this document. If vehicle is not covered under the above emission extended warranty or the complaint continues to occur, then proceed as follows: Check for available software updates to the ME (N3/10). If updated software is available, perform the update, clear the DTC and the perform each of the "WARM START" and "COLD START" test drives listed below twice. If the code does not re-appear then release the vehicle. If there is no new software available OR the DTC returns after the test drives then perform the following steps: • Drain the coolant through a fine mesh sieve and check for signs of debris. Additionally, inspect the coolant reservoir for debris. If any debris is found take pictures of the reservoir and the mesh filter and "flush" the system at least 2-3 times to clear as much of the debris as possible • Replace the thermostat and bleed the system as outlined in AR20.00-P-1142-04A, evacuate the system for 20-30 minutes instead of the 5 minutes specified in step 22 • NOTE: Please use all the tools specified in the AR document. The DTC will continue to populate if the circuit is not properly bled • NOTE: There are two valid thermostats to choose from in the parts section of this LI. Please verify which PN is applicable for the vehicle being worked on via XENTRY Parts Information • After bleeding the system clear the DTC and perform each of the "WARM START" and "COLD START" test drives listed below twice. If the DTC does not reappear after the tests, release the vehicle If the ME (N3/10) software is up to date, the thermostat has already been replaced, and the complaint persists open a TIPS case and attach the following documents: • Initial quick test • ME (N3/10) control unit log • The results of an R48 test from a “yes” response and from a “no” response • Pictures of the coolant reservoir and mesh sieve (mentioned above) WARM START · Begin with the engine coolant temperature at approximately 50 degrees C · Activate the AC system, if defrost is not in use open the windows · Drive the car normally until a coolant temperature of 75 degrees C is achieved · Depress the accelerator pedal 50% for ~5 seconds (partial acceleration) · Let off the accelerator pedal and let the car coast for ~10 seconds · Continue to drive the car normally COLD START · Drive for ~7 miles (normal driving) · Shut off the engine in a parking lot (or similar), wait 30 seconds, then restart and continue driving · Depress the accelerator pedal 50% for ~5 seconds (partial acceleration) · Let off the accelerator pedal and let the car coast for ~10 seconds · Continue to drive the car normally

Complaint Complaints of a harsh 3to4 upshift Cause Lost torque adaptation values and negative fill times of clutch K27. Remedy Short-term measure: Note: All steps—including resetting the learned values and performing the stationary adaptation—must be completed to resolve the concern. 1. Perform IPR and follow the provided instructions. 2. Perform software update if available (IPR will automatically check for status of software availability) 3. Perform Special Function "Resetting of learned values 'Deceleration Mode'" (VGS > Special Procedures > Special procedure > Resetting learned values Deceleration mode) 4. Complete the standstill adaptation Long-term measure: A software resolution has been released for several model years with software levels 22A.3 (n3g222aa03ub) and 22A.4 (n3g222aa04ub). - Check VGS control unit log or eeprom .txt file for "Program Status" to determine your vehicle. Software is in the approval process for MY23 with 22A.3. Once the software is released, an update on availability will be added in IPR and in this LI document. As of 6/8, software released for the following model years: MY26 with 22A.4 A001 902 25 21 >> A001 902 96 21 MY24+MY25 with 22A.3 A000 902 26 99 >> A001 902 97 21 If the vehicle software level is not 22A.3 or 22A.4: A software resolution will not be created for these vehicles, please follow the short term solution to alleviate the concern.

Complaint Crackling and cracking noise from the outer wheel on the front axle when cornering Cause The noise is generated by a micromovement on the contact surface between the rim and the brake disk (wheel bolt group) and may be intensified by potential soiling. The more lightweight rim (AMG forged rim) transmits the noise louder; in the case of cast rims, the noise is generally not perceptible. This is not a technical defect, but rather a complaint concerning comfort. Safe operation of the vehicle is ensured at all times. Remedy Important note: The operations described below do not represent a permanent remedy in every case. The noise may reoccur again after an indefinite period of time; sanding the rims with abrasive media multiple times is not permissible. Only cleaning using the Hazet tool 4960-160 (recommendation) can be performed without any concerns each time the wheel is changed or if the complaint reoccurs. Replacing the parts (rim, wheel bolts, wheel bearings, wheel hub, brake disk) is not expedient in the event of this complaint. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Clean the components of the wheel bolt connection according to the WIS instructions Sand down the rim and brake disk bowl by performing the following steps: • Manually sand rim (old design only) in area of water drain bores (Figure 1; item A), approx. 1.5 cm left and right of water drain bore (Figure 2) Note: Use abrasive paper with grit size 80. The grooving in this area should no longer be visible (sand down approx. 0.1-0.2mm) • Also sand brake disk bowl using emery cloth or abrasive paper with a grain size of 120 • For vehicles equipped with the AMG ceramic brake system (B07), abrasive paper may not be used for cleaning on the brake disk side Note: Do not use any cleaning agent when cleaning on the rim side. Cleaning using abrasive paper with a grain size of 80 will suffice. Do not apply any grease, lubricant or paste after cleaning The brake disk bowl should be "bare metal" in the area of the imprints made by the hole (Figure 3)

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).

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 Do not replace parts. Please open a TIPS case to the Body/Chassis/Entertainment inbox but read the below carefully: • The vehicle must be exhibiting the concern as shown in the attachment videos. • The vehicle DOES NOT need to be at the dealer, nor does it need to be brought into the dealership. • If the geographic location is known, it is very important that it is provided. • Provide any pictures or videos, if available. A new software for the head unit is scheduled for tentative release in Q3 2026.
