Wheels
Filed Nov 24, 2025SC
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.

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.

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 and all of a sudden. The car felt like it was swirling left and right and I was trying my best to straighten the steering wheel, but it felt like I had no control of the car. I eventually hit the median on the road and while all this was happen my dashboard was flashing with all the lights, but my eyes were on the road trying to fix the steering wheel so I don’t know exactly what light was on. When I hit the median, I was finally able to regain full control of the car. It kind of felt like my car was accelerating and swerving at the same time and I was not even stepping on the pedal. I am not sure what caused this, but my car was recently in the shop for some battery issue.

On four occasions my car has stalled while in traffic very early in my ownership and then it happened again today with my family in the car and nearly caused an accident. The entire dash lights up with every warning when it happens. Sometimes the check engine light comes on after I shut the car off and restart it. My Mercedes dealer has had it in multiple times for this reason. The last time it was in for this (May of 2022) they "reprogrammed" the entire car. It happening again today has really made me lose a lot of faith in the vehicle, especially since we purchased it for the safety factors. I read online that there are many others who have experienced this. Some say it is related to the 48V battery. I don't care what Make or Model or how expensive it is, a new car should NOT stall in traffic and should be looked into. Thank You.

I was driving down the interstate and heard a loud ‘pop’. Very confused, my daughter and I saw a couple pieces of glass fall from the sunroof. Looked up to see the sky and hear the wind. Luckily, I had the shade closed. I pulled over right away to see a big hole in our sunroof. It seems as though this is a problem with Mercedes and they’ve had a recall in the past. When I took it to the dealership, I was told something had to have hit it. That that haven’t had any recalled sunroofs at their location. I definitely would have seen something fly over my car big enough to make a big hole in the sunroof. I’m very thankful no one was injured. But this needs to be addressed! They are taking no responsibility at all!! People need to be warned that this could happen! Others may not have the outcome we did.

As the contact attempted to steer around the pedestrian or object in the lane of traffic, the safety feature independently jerked the vehicle back into the lane and into the pedestrian or object he attempted to avoid. The contact stated that a RED icon alert would appear on the instrument panel that the vehicle was encroaching the opposite lane of traffic, which caused the safety feature to be activated. The contact stated that the safety feature could cause more harm than good because he nearly hit other pedestrians because of this feature. The dealer nor the manufacturer were notified of the failure. The vehicle had yet to be repaired. The failure mileage was unknown.

The car would not start and could not be jumped. I'm told it's the 48V battery has to be replaced. I have seen on the internet numerous people have the same problem and that a large batch of these 48V batteries are the problem. Error message displays stop the vehicle and more details advises battery is malfunctioning and do not continue driving.

No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
