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.

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.

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.
