My 2022 Mercedes GLE450 had water intrusion from the an AC vent hose that was not 'fixed' properly by Mercedes after they issues a recall for ALL 2020 and 2021 GLE450's. It took 9 months, endless gaslighting from Mercedes that I flooded the vehicle myself, a failed state-sponsored arbitration hearing only to find out Mercedes did NOT properly diagnose the vehicle from the start. I had officially 'given up' after almost a year of fighting this was not my fault, only to drive disassembled passenger seat and floor area down to Mercedes... to see the vehicle dripping water right into where nearly $20,000 of electronics were compromised. Mercedes has since fixed the vehicle, under warranty, yet they did NOT tel lme anything until the day the vehicle was fixed that it would be covered under warranty. They keep this away from the local dealer and had a traveling technician work on the vehicle to keep it entirely under wraps. I genuinely hope Mercedes is held accountable for taking full advantage of their customers while admitting (at least locally) that the 'fix' for the previously recalled vehicles is inadequate. Water intrusion, causing shorting of electronics and potential fire is a MASSIVE safety concern and they need to not only be held responsible yet held responsible for the pain and suffering caused by gaslighting customers and KNOWINGLY committing insurance fraud by forcing their customers to file insurance claims after not properly addressing the recall.

Vehicle fails to accelerate when the accelerator is pushed all the way to the floor. Maximum acceleration is 20-25 mph. The vehicle is available for inspection upon request. My safety is greatly put at risk in normal traffic conditions due to the inability to accelerate. I am also unable to drive on the highway or anywhere requiring higher rates of speed. I am also unable to quickly remove myself from a dangerous traffic situation where acceleration is required. The dealer confirmed the problem but has been dishonest about the source of the problem and whether it has truly been repaired. First they said it was a software problem that they could not fix. Then they said it was a hardware problem. They replaced the hardware, but have never confirmed that it was not also a software problem. The vehicle has been inspected by the dealership. The engine light came on. This first appeared about 3 days before the problem started.

Complaint Customer concern of Air Conditioning not cooling. *NOTE ‑ Use of tracer DYE for leak checks is not approved. Only approved leak check procedures as per WIS are approved. Cause Possible refrigerant leak. Remedy Perform the following measures : *Important* ‑ Photo documentation requirement is no longer in effect as of 10/1/2025. Remedy 1: Replace Evaporator (Only applies to vehicles produced PRIOR to April 15, 2022 and has NOT had the evaporator replaced previously) 1. Ensure that the rest of the AC system has been thoroughly checked for leaks with forming gas as per WIS before condemning the evaporator. 2. If no other leaks are found, replace the evaporator 3. *Important* ‑ when you get the new evaporator, check the expansion valve bracket to see if there are any bends (see attachment "Bent Bracket"). a. If bent, remove the expansion valve and bracket and check for damage to the flange (see attachment "Flange Damage"). i. If damage is found, order another evaporator and claim the part under parts warranty. The warranty claim MUST include a photo of the damage found. ii. If no damage is found, flip the bracket and torque to 7Nm. Check the evaporator for proper sealing before fully installing. b. If no bends are found, the evaporator should be installed in the vehicle. Note ‑ *If the evaporator housing has been opened or the evaporator or housing has been tampered with, the claim will be debited. Remedy 2: (Applies to all vehicles produced on or AFTER April 15, 2022 up to August 1, 2025) 1. Ensure that the entire AC system has been thoroughly checked for leaks with forming gas as per WIS . 2. If no leaks were found AND the system came in with no cooling/low charge, OR the evaporator is suspected of leaking: 3. Replace ONLY the expansion valve bracket, seals, and bolts as supplied in kit A 167 832 47 00, in accordance with the procedure outlined in WIS document AR83.30‑P‑5520ME. 4. IF THE PRODUCTION DATE IS BETWEEN JUNE 1, 2023 AND JULY 1, 2024, REPLACE THE DRYER AS WELL. (NOT THE CONDENSER) 5. After, charge the system and perform a few drive cycles. 6. Recheck the vehicle for leaks. 7. If no leaks are found, the vehicle can be released. 8. If a minor leak is detected that is less than 50ppm, then perform the following steps: • If a leak is detected, fill the system with forming gas • Close all doors and windows for 10 minutes. • Vehicle off with no blower activation. • Open the driver's door and measure ppm detection as soon as the door is open and the sniffer goes into the vehicle. • If no leaks are measured, fill the system and release. • If you still feel the evaporator is needed/leaks are still detected, a TIPS case is required for replacement. Provide all documentation listed in Remedy 3. Remedy 3: (Only applies to vehicles produced AFTER August 1, 2025) Ensure that the entire AC system has been thoroughly checked for leaks with forming gas as per WIS . If no leaks are found or the expansion valve has been found to be leaking, remove the expansion valve and check the bracket. If the bracket is bent, replace the expansion valve bracket, seals, and bolts as supplied in kit A 167 832 47 00. In the warranty submission, include photos of both sides of the bracket and a side profile so it can be seen that the bracket is bent. If the bracket is NOT bent or leaks from other locations are found, then open a TIPS case with the following: 1. Initial Quick Test 2. Create a short video of the actual pressures via AC machine, showing the engine running, and hold a copy of the VIN/RO in view as well. 3. OBS recording of XENTRY AC actual values of compressor request to be on and current value. (Instructions in Attachments) 4. Video recording of the leak being found via sniffer at the R/F AC drain after removing the under dash panel if the evaporator is suspected. (see attached videos) 5. If the evaporator is found to be leaking via sniffer, another video needs to be uploaded (or a continuation if only making the video after checks

Complaint Customer complaints relating to automatic transmission 725.0 (NAG3 Classic /9G‑TRONIC automatic transmission) and 725.1 (NAG3 facelift/9G‑TRONIC automatic transmission facelift) For faster, more effective and more targeted diagnosis, Intelligent Predictive Repair (IPR) has been developed and integrated into XENTRY Diagnosis. This ensures an automated diagnosis process. Cause As part of the on‑going quality monitoring process and associated quality and damaged part appraisals, a high number of ineffective repairs have been discovered. Such ineffective repairs have a negative impact on all those involved. For the customer, it means high costs and long repair times and for the dealer, it may result in the warranty claim being rejected. Remedy General note: IPR is available for: ‑ NAG3 Classic (automatic transmission 725.0) ‑ NAG3 Classic ‑ AMG sport model (AMG 43 and AMG 53 with converter, automatic transmission 725.0) ‑ NAG3 Classic ‑ Hybrid (automatic transmission 725.0) ‑ NAG3 Classic ‑ AMG 63 (automatic transmission 725.0) ‑ NAG3 MOPF ISG2 (automatic transmission 725.1) ‑ NAG3 MOPF Hybrid (automatic transmission 725.1) ‑ NAG3 MOPF AMG sport model (AMG 53/AMG 53e with ISG48V2 & converter /hybrid, automatic transmission 725.1) ‑ NAG3 MOPF AMG 43/63 with engine 139/177 (automatic transmission 725.1) Steps for the Service Advisor: Important: The more information and detail that can be given to the workshop about the complaint, then the more effective the subsequent diagnosis with IPR can be. To this end, a detailed service reception questionnaire has been provided to help the Service Advisor ask the right questions about the complaint. ‑ Ask precise details about the customer complaint and the conditions and context. ‑ Fill out the service reception questionnaire (please see WIS document: OF27.00‑P‑3000‑05A) for customer complaints in detail and forward it to the workshop. Operation steps for the workshop employee: 1. Perform quick test 2. Access the transmission control unit via XENTRY Diagnosis 3. Select "A customer complaint has been received" and carry out all subsequent operation steps (IPR diagnosis path). 4. The IPR repair instructions are displayed, Carry out the IPR repair instructions without performing any further diagnostic or repair steps. ‑ Important: The IPR repair instructions are binding and must be carried out. Differing repairs are possible; such repairs must be documented in XENTRY in free text. Please observe the information regarding the IPR diagnosis process in XENTRY. Conventional diagnosis and subsequent appropriate repairs are only permitted if IPR does not specify any repair instructions. Invoicing for the guided IPR steps: Operation item 27‑0640 and 0.1 hours Notice regarding warranty: The use of IPR in association with warranty claims is mandatory! If the IPR repair instructions are disregarded without justification, the warranty claims may be rejected and/or are subject to debit. IPR will provide a measure to repair the vehicle based on various data sources (EEPROM, fault codes, etc). Please consider the vehicle maintenance record of the vehicle. For warranty and goodwill repairs, the transmission ECU test log and/or IPR test result must be uploaded into Paperless XENTRY Diagnosis (pXD) . If repair is being determined based of oil pan condition pictures of oil pan MUST be provided to warranty as justification. ·Tamper‑proof documentation: The IPR repair instructions are stored in the control unit log.

If fault code reoccurs during road test: Install new directional control valve.

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.
