When I got gas the estimated range indicated 308 Miles. We traveled approximately 134 Miles the estimated range was at 86 Miles it was dropping rapidly but average miles indicated 26.5 MPG. The next day we added fuel again and we were at 382 Miles. Then we drove 70 miles and the fuel indicator was showing that our range only decreased 15 Miles. During the trip the range increased multiple times and between the two days we traveled we did not know how much fuel was left in the car. The first trip it showed that we burned half a tank and the second day it showed we hardly burned any gas. This particular model has Open Recall for fuel pump system issues and display software. We were afraid that we were running out out of gas and would not be able to complete our trip or run out of gas in the middle of the highway.

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.

A safefy recall was issued December 2023 for my vehicle. I received a recall notification letter dated February 2024. The letter stated that the fuel pump impeller mighe deform contacting the fuel pump housing causing the fuel pump to stop operating. As a result the vehicle could lose drive power and increase the risk of a crash or injury. As a result I am reluctant to drive my vehicle far from home. I'm told after nearly five months there is no remedy. Someone at the local dealership said the remedy is available but had not reach the area where I live. As a customer I am totally dissatisfied with the handling of this safety 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.

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.
