WHEELS
Both rear wheels on this vehicle have developed cracks which leads to tire pressure loss. Apparently, this is a common issue with Mercedes' heavier vehicles like the GLS and S series sedans. To be clear, I did not hit anything. I did not do any unusual driving. Both rear tires are fine. While you expect that certain components on a vehicle will have problems, it is also reasonable to expect that wheels will not crack prematuraly. Mercedes is aware of the problems. They were named in a class action lawsuit that was dismissed because cars were out of warranty. Warranty or no warranty, this is a major safety issue as a loss in tire pressure can be catastrophic.

Fire
ELECTRICAL SYSTEMSEATS
On [XXX], I was heading home from work traveling [XXX] on [XXX] through Atlanta's usual heavy traffic. I smelled smoke inside my car and saw fire flames coming from under my passenger seat. My initial reaction was to try to put the fire out with my hat without burning myself. Also, I had to try to navigate across multiple lanes of traffic without hitting anyone and avoiding anyone hitting me. Safely, i reached the side of the interstate and exited the vehicle. As I stood from afar watching my vehicle burn; the reality sat it that a few minutes earlier that could have been me trapped burning inside, injured or even death because something had failed in my vehicle. Later, when I finally arrived home, I started researching on the internet to see if anyone else had experienced problems with their MB 450 GLS catching fire. Surprisingly, I found that recalls had been issued in April 2022 and March 2024 for a possible fire risk from a 48volt loose ground wire issue under the passenger seat. At that time supposedly there were no reported injuries or crashes related to this issue until now. If I am the first to witness this issue, then so be it because I saw the fire burning from inside under my passenger seat before it FULLY torched my vehicle I reported this issue first to Progressive Insurance and Mercedes-Benz Corporate. Progressive has provided my transportation according to policy for my first 30 days. As I approached the end of my rental period, I spoke with MB Corporate to see if there was anything that they could do as far as providing me transportation. I was told that there was nothing that they could do because they were not a dealership with cars to loan. The joint vehicle fire investigation was schelduled for 29 April 2025. On 25 April 2025, Progressive informed me that MB Corporate had moved the fire investigation date to 29 May 2025. NOW, what am I suppose to do? It has been almost two months that I have been without a vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

ELECTRICAL SYSTEM
Vehicle has just over 31k miles. ON multiple occasions, the vehicle randomly shuts off and displays a 48 volt battery error on the screen followed by a check engine light. This has happened in the middle of a busy intersection and at 75mph on the interstate. Each time it does this, I have taken it to a Mercedes dealer for repair/troubleshooting. THey perform the Mercedes required steps to repair the known issue and each time the issue persists. The car has been at a dealership for almost a combined 30 days now with no end in sight. I do not feel safe knowing that Mercedes cant seem to solve the problem and instead puts me back on the road knowing the car is not right and risks injury to my family as the issue has happened at low speed and high speed resulting in extremely dangerous situations for my family. I have 2 open PTSS cases with Mercedes USA (246121906 and 246113294). Researching this issue has revealed this is a known issue with their "mild hybrid" SUVS and many consumers have the same or similar experience to mine.

I was driving only 30mph through my suburban neighborhood bringing my kids to school in the morning when a loud shotgun sound hit my car causing me to be distracted and distraught. My entire sunroof had exploded on me for no reason. Mercedes is currently undergoing a class action lawsuit for this. But since it is not completely yet, I’m being told I need to pay $3700 out of pocket for the default damages and servals days without a vehicle.

Vehicle was purchased pre-owned. Mercedes Me is still associated with previous owner. Mercedes unable to remove association at dealership or on the phone. I can provide bill of sale and identification. Previous owner can remote start, track and control the vehicle I own. This presents a clear and obvious security and safety issue. I am not prepared to drive to *another* dealership and ask *again* to get this done. I own the car and the previous owner can do whatever they like with it. Unacceptable.
