2022 Mercedes-Benz AMG GLE53

The panoramic sunroof exploded upwards and outwards while driving under normal conditions. It created an extremely loud and startling sound that left the driver and passenger stunned. We were fortunate there was not an immediate oncoming vehicle as we likely would have struck head on. Shortly after the explosion, tiny shards of glass began to fall into the passenger area. We were also fortunate to be able to get the vehicle safely off the road. The vehicle was brought to the dealership and the manufacturer was called. They are all pretending they have never heard of something like that happening when a quick search reveals this is a known manufacturing defect with a class action lawsuit filed. The named plaintiff is actually a customer from the very dealership we brought the vehicle to for service. There is no chance they are not aware of the problem.

Vehicle has issues maintaining power and attempts to stall in traffic. It also shakes violently at idle. It was diagnosed by the dealership and determined that the cylinder head was damaged and needed to be replaced for $7200.00 since there was no warranty. Vehicle was purchased used and the Issue was noticed 6 months after purchase at 70-80 thousand miles. After researching the issue, this appears to be a known problem with the 4 cylinder Mercedes vehicles, but only specific models were covered under the extended warranty for replacement.

Nov. 7, 2025 - After returning home around 4pm, I parked the car in my garage, and entered my home. Due to the sound of the fan motor which stays on after you shut off the car, it is possible that the engine was still running when I thought it was off. Please note that my garage is attached to my home. Around 1am I awoke and went into the bedroom on the far side of my home which sits directly above my garage. When I entered this room I heard a noise, like some kind of motor but at the time I had no idea what this was. As I walked through my home, went downstairs and neared the doorway to my garage when I realized the loud noise was coming from my garage. It was not only frightening but extremely concerning and come to find out my Mercedes was running, in fact it had been running since I got home earlier in the afternoon. Please note that one of the most critical things that happened is that upon opening the door to the garage I was exposed to severe carbon monoxide fumes. I discovered the car sitting there, running, for no reason at all, the outside was very hot to the touch and I panicked. I was breathing in fumes that could affect my life! I ran to the kitchen, grabbed a fan, opened the garage doors and immediately went upstairs to see if my daughter was okay. As you know carbon monoxide can kill you and I did not know why in HECK this was happening. - This car is still relatively new with low miles. - This vehicle is also supposed to be equipped with significant safety features and it is difficult to exit the car without alarms sounding and appearing on the dash telling you the car is still on. - Mercedes, however, already made me take this car in twice to address multiple recalls affecting safety! I also had it serviced not less than 3 weeks ago. - Mercedes is completely skirting/ignoring the critical issues with this vehicle and has sent me a FORM letter denying assistance. There could have been 2 fatalities and I have been ill since this happened.

On March 30, 2023, my 2022 AMG GLE 53 check engine warning light came on. I immediately called Capitaleurocars the Mercedes Benz dealer. On May 1, 2023, according to the Capitaleurocars service order, the technician noted the following: "found the check engine light on" then performed "a guided test for fault code (P146264) and found fuel pressure and temp sensor passing test." The technician wrote "Checked PTSS cases and checked for related LI documents. Found LI-47.50-p-070263 which states that software is under development for this issue. no software available at this time. Cleared code and released back to customer." Capitaleurocars service department could not tell me when the software update would be issued, but I would be notified as soon as it was released. I was also told that on September 6, 2022, a temperature sensor was replaced on the vehicle due to the check engine warning light being on. I asked if the issue on September 6, 2022, was the same issue I was having and I was told yes, it was the same fault code. So, approximately a month before I purchased the car on October 1, 2022, the check engine warning light was on and a temperature sensor was replaced. The Capitaleurocars service department suggested I call MBUSA Customer Service to get more information about the software update. I researched the LI document number and found that NHTSA had received a complaint on 06/25.2020, with same the LI 47.50-p-070263 document number and fault code P146264. The complaint to NHTSA was on a GLE and noted as follows: Complaint: Check engine light active and FC P146264 Temp. and pressure sensor B4/7 is stored in engine control unit and tank control unit. Cause: Software parameter in Fuel pump control unit Remedy: Update SW in FSCU control unit Capitaleurocars Service Department did confirmed that the fault code found on my car on May 1, 2023, was the same as the one reported to NHTSA on 06/25/2020.

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 CEL light on with no drivability concerns. Cause Signal timing error. Remedy 167, 465: SW has been released. Update the FSAM to the latest SW version. 290, 118, 243, 247: Software is still in development. This fault code does not cause a drivability concern and will clear itself within 2-3 key cycles. The vehicle can be released back to the customer.

Complaint Noise from front end attributable to steering gear. Cause During diagnostics of a front end noise, workshop is under the impression the noise is coming from the steering gear. Remedy Workshop diagnostics point to the steering gear as the root cause of the noise and the below LI's and items have been ruled out. • LI46.35-P-067339 - "Rattling or Humming Noise When Steering" • LI46.35-P-071461 - "Check Tie Rod Outer Joint of Steering Gear" • LI46.10-P-077391 - "Knocking Noise In The Area Of The Steering Gear or Steering Column Tube When Braking Or Moving Off; The Steering Wheel Can Also Be Felt To "Crack"" • If the noise is described as "clacking" or "knocking" and the thrust element in the steering rack has NOT been checked yet, please perform a check and subsequent adjustment, if necessary, as detailed in AR46.20-P-0601ME. If the above has been completed and the noise is still present, please continue with the below: • Video underneath the vehicle with clearly audible noise. • Video inside the vehicle with clearly audible noise. • Vehicle checked for history of collisions. • List of other checked components (suspension, drive line components, wheel bearings, etc...). • Check integrity of dust boots and dust boot clamps. Ensure no water has entered into the steering rack. • Along with the audible noise, does the feel/noise change through only a certain part of the steering arc sweep? • Provide the thrust element before and after readings. If the above is completed and no findings are noted, please open a TIPS case to the Body/Chassis/Entertainment inbox.

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.
