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.

Complaint Noise from front end thought to be from steering gear. Cause During diagnostics of a front end noise, workshop is under the impression the noise is coming from the steering gear. Remedy If the root cause of the noise cannot be found and is seemingly from the steering rack, perform the below LI's and diagnostics. If they have been performed and the root cause still cannot be determined, a TIPS case must be opened to the Body/Chassis/Entertainment team prior to replacing the steering rack. • LI46.35‑P‑067339 ‑ "Rattling, Humming, Dry Sliding/Gravel 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"" • 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. Keep the boot clamps in case the rack is returned. • If the noise is described as "clacking" or "knocking" when moving the wheel back and forth in quick oscillations 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. • Remove sway bar links and see if noise persists. • Perform NVH time‑domain noise diagnosis pointing to the steering rack as the root cause. The TIPS case must contain the following: • Video underneath the vehicle with clearly audible noise while engine is running. • Video inside the vehicle with clearly audible noise while engine is running. • Vehicle checked for history of collisions. • Vehicle history checked for other noise complaints in the area. • List of other checked components (suspension, drive line components, wheel bearings, etc...). • 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.

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)
